Welcome

Welcome to our autumn/winter edition of Clinical Connections, the NAS Medical Directorates clinical magazine. We have really positive feedback from our first two editions, so a big thanks for all the feedback and suggestions. It’s so important that we get your input and cases to continue to make this publishing relevant to you the frontline practitioner. So if you are interested in contributing please drop us an email to medicaldirector. nas@hse.ie. We will be happy to support you in developing the concept and structure for your chosen subject or case. On the other hand if you think you have it roughly nailed, then don’t doubt yourself…. just send it on and we can work through the fine details between editions.

I would also like to take the opportunity to thank all the contributors. In this edition we have a broad mix of subjects, two great cases, one on pain management of the non-verbal patient and another on Autonomic Dysreflexia. We have articles on paediatric trauma care, human factors in resuscitation, the introduction of the Electronic Patient Care Report (ePCR), Penthrox and some excellent learning from the tele-medical support line. Once again we have some great pics from around the country. We hope you enjoy our next edition.

This publication was made possible with the kind support of

News from the Medical Directorate Over the past few years the use of prehospital Ketamine for analgesia and sedation has increased by our international EMS counterparts. The 2016 PHECC Clinical Practice Guidelines introduce IV Ketamine as an analgesic option for use by Advanced Paramedics. The rollout will commence with the release of the CPG’s and associated upskilling in 2017. In advance of this development the NAS Medical Directorate is trialling the use of Ketamine by

Emergency Aeromedical Service Advanced Paramedics. The trial allows EAS APs to use Ketamine for both analgesia and sedation where required. This is a significant step forward in patient care and in Advanced Paramedic practice. As we go to print we have had seven successful cases recorded, five analgesic doses and two sedations. We are looking forward to providing a detailed article on our progress in the next issue of Clinical Connections.

Ask The MEDICAL DIRECTOR

Q

Brian Hassett Paramedic, South East

I wish to query the reason why we cannot administer Midazolam through the intranasal route as in the PHECC guidelines for Adult Seizure 5/6.4.23 Version 3,02/14 page 46 as well as the paediatric seizure 5/6.7.33 version 3,02/14 page 87 it clearly states that for paramedics it can be either the buccal or IN route? I also wish to ask are there any plans to introduce any other medications that paramedics could administer intranasally as with the ability to cannulate been just an AP skill the intranasal route presents a safe and effective route that is proven and evidence based. Regards Brian Hassett.

A

Dr Cathal O’Donnell Medical Director

Brian thanks for your question. When the CPGs you reference were published we analysed the implications of authorising both routes of administration or just one, based on both being equally effective. The main consideration was that midazolam is a controlled drug as per the Misuse of Drugs Act, which puts certain requirements on us regarding its storage and use, as well as record keeping and drug reconciliation. Had we introduced intranasal midazolam, because it is supplied in an ampoule, we would need to replicate existing procedures for Advanced Paramedic use of midazolam ampoules, including putting in a second drug safe in every station. Because the two routes of administration are equally effective, we chose to implement the buccal route only – the medicines management requirements of the buccal midazolam are more straightforward.

CLINICAL CASE REVIEW

Pain management in the non-verbal patient

As practitioners, we need to increase our awareness of pain in the non-verbal or dementia patient and be strong advocates for those patients We were dispatched to a heath care facility requesting to transfer a patient who had dislodged his urinary catheter. On arrival to the bedroom, we found a large elderly man with cognitive impairment trying to remove a Foley catheter, physically being prevented to do so by multiple nursing staff. The patient was non-verbal but obviously distressed, agitated and grimacing. The handover included a report of a non flowing urinary catheter with haematuria in the previous hours, a full bladder and a recent CVA without any other significant comorbidity. In consultation with the referring doctor, we administered Fentanyl 50mcg Intra-Nasally. Within a couple of minutes the patient was relaxed enough to be safely transferred onto the ambulance stretcher, have his vital signs obtained and an IV access gained. A gram of paracetamol IV was administered on route to the receiving hospital with urology surgery capabilities. The patient remained comfortable and haemodynamically

stable during the transport. The patient remained comfortable the next few hours in the Emergency Department without the addition of any other analgesia. A Suprapubic catheter was inserted in the ED by urology surgeons with infiltration of local anaesthetic. LEARNING POINTS Analgesia in the nonverbal patients (dementia, paediatric and special needs) is being reported as suboptimal in prehospital systems, Emergency Departments and other health care settings around the world. The barriers to administration of analgesic agents to this population are still not well understood. Some suggestions that have been put forward are educational (lack of pain management education in medical schools, reliance by heath care professionals to Numerical Rating Scale and Verbal Descriptors Scales for determination of analgesia needs), and psychological factors (dismissal of patient’s pain rating based on own experience, fear to overdose and fear of being seen to over use opioids). Irish prehospital care is one of the very few worldwide to have a pain management strategy beyond chest pain, we,

as practitioners, need to increase our awareness of pain in the non-verbal or dementia patient, be strong advocates for those patients and improve our education around understanding pain, pain management options and analgesic agents. Titration of opioid analgesic agents is very important in the elderly population due to the change in their renal and hepatic function, particularly when it comes to repeating the agent. The literature is suggesting a titration between 25% and 50% of the loading dose until desired effect are reached. Using medical oversight consultation to maximise the patient outcome; in this case the refereeing and treating physician was still on location, was able to confirm the indication, lack of contraindication, and appropriateness of the analgesia plan with an alternate route of administration (IV paracetamol).

CLINICAL CASE REVIEW AUTONOMIC DYSREFLEXIA

INTRODUCTION: At approximately four o’clock in the morning we were dispatched to a private residence for 70 year old man with a severe headache. The location was 18 km from the receiving hospital. On arrival we were presented with a tetraplegic patient in a nursing bed, complaining of an acute onset of headache starting approximately an hour prior to call. For once the patient’s home was well laid out with purpose built double doors leading to an open plan interior. The patient’s bed, with hoist, was positioned in the middle of a large living room with all necessities and modern conveniences such as phones and controls to hand. Our assessment revealed a blood pressure (BP) of 210 mmHg systolic with a regular pulse of 90bpm, apyrexic, GCS 15/15, capillary blood glucose 14.2 mmol/L, respiratory rate of 20bmp unlaboured, 96% oxygen saturations, pale in colour. The patient was overweight but not obese. Previous medical history: stroke 14 months earlier, tetraplegia from RTC 30 years previously (car versus pedestrian). Medications: GTN, Warfarin, atenolol, paracetamol. Also had recently finished an antibiotic course for a respiratory tract infection. No known allergies. The patient’s full time carer stated that there was a reduced outflow from the urinary catheter in the previous 8 hours. She was very aware of the complications and dangers of a blockage or compromise of a catheter in a tetraplegic patient and therefore called for the emergency services on first noticing the associated symptoms.

Autonomic dysreflexia The patient was moved to ambulance stretcher and ambulance. En route the patient’s BP decreased to 190mmHg systolic while in a sitting position on the stretcher. Patient was relaxed and talkative but the headache remained. A FAST assessment was of limited use at this stage but there was no noticeable deficit to speech or GCS according to the carer. Concern was heightened due to the fact that the patent was bed bound, Tetraplegic and had history of previous stroke. The transport until the handover to the Emergency Department was uneventful. The nursing staff were cognisant of Autonomic Dysreflexia symptoms and attended promptly to the patient.

PATHOPHYSIOLOGY: Autonomic dysreflexia is a potentially life-threatening episodic hypertension that develops in 50-90% of people with tetraplegia or high paraplegia. Autonomic dysreflexia occurs after spinal cord injury at or above the T6. Because injury at this level leaves the sympathetic nerve branch of the extensive abdominal circulation isolated from the brain stem, spinal reflexes are left unrestricted. Stimulus or pain releases substances such as noradrenaline and dopamine which cause severe vasoconstriction with skin pallor, goose pimples and sudden rise of blood pressure below the spinal injury. The rise in blood pressure is detected by baroreceptors in the aortic arch and the carotid bodies, triggering a parasympathetic response via the vagus nerve in form of compensatory bradycardia and vasodilatation. However both of these mechanisms are insufficient to control extensive vasoconstriction in the relatively larger body area below the spinal cord injury. If unrecognised or untreated promptly the patient can develop intracranial haemorrhage, seizures and coma, or cardiac arrhythmia such as atrial fibrillation, other re-entrant type of arrhythmia or myocardial infraction, and death. Signs and symptoms includes: »» Rapidly increasing headaches. »» Rapidly rising blood pressure. »» Bradycardia, new onset of atrial fibrillation or other arrhythmia. »» Flushing and sweating above the spinal cord injury and, below the SCI, pallor, gooses pimples. »» Some patient may have other warning signs specific to them. Blood pressure is deemed elevated if at least 20 -40 mmHg above the normal resting systolic reading. It is important to remember that a BP for individuals with paraplegia or tetraplegia may usually be low, around 90 -100 systolic lying

down and possibly lower in a seating position. Be sure to inquire about the patient’s baseline reading, as they may become symptomatic with “normal range reading”. Common triggers include: »» Bladder (distended or severely spastic bladder, urinary tract infection, bladder or kidney stones). »» Bowel (constipation, faecal impaction, rectal irrigation, haemorrhoids). »» Skin (tight clothing, pressure area, ingrown toenail, burns). »» Others (any irritating stimulus below the level of SCI including fractures, testicular inflammation, distended stomach, labour or severe menstrual cramping). Women with SCI, who are pregnant, may experience autonomic dysreflexia as the first sign of the commencement of labour. »» Iatrogenic (inserting, clamping or kinking a catheter, or other urological procedure). Prehospital treatment: »» Ask patient or carer if they suspect the cause. »» Monitor BP every 2-5 minutes. »» Elevate the patient’s head and lower the legs (may help to lower the BP) »» Loosen any constrictive clothing, belts, and supports. »» Check bladder drainage equipment for kinks or other obstructions to flow. »» Avoid pressing on the bladder. »» Initiate rapid transport with Advanced Paramedic intercept (Medical Oversight may give advice on using GTN and analgesia). »» Pre-alert Emergency Department. CONCLUSION: Autonomic Dysreflexia is a rare occurrence in the prehospital area and may be more prevalent during routine transfers. Just like in the case illustrated above, the patient and carers are usually aware of the condition; they have been trained and advised by the Spinal Injury Rehabilitation staff to frequently monitor the blood pressure and the urinary catheter flow. We, as practitioners, need to understand the danger of this condition and recognise the need for prompt transport, treatment and ED pre-alert. REFERENCES: Middleton, J. Ramakrishnan, K. Cameron, I.

EVERY ACTION COUNTS

Understanding Human Factors in Cardiac Arrest The skills of chest compressions, defibrillation, intravenous cannulation and rhythm recognition are considered typically to be the most important factors in managing a cardiac arrest. These are all technical skills that are learnt from books, lectures, courses and peers. Although they are important for the successful resuscitation of a patient, there is another group of skills that is becoming increasingly recognised in resuscitation - human factors or non-technical skills. Nontechnical skills can be defined as the cognitive, social and personal resource skills that complement technical skills and contribute to safe and efficient task performance. The 2015 ILCOR guidelines now recommend leadership training in ALS and ACLS courses, to support the leadership role in OHCA Management the National Ambulance Service is restructuring its Cardiac Arrest Management Module to support the principles of High Performance Resuscitation and Team Leadership. Crew Resource Management (CRM) encompass expertise, experience and research from the aviation industry to improve the safety and efficiency of organizations involved in risky work. CRM teaches us about human limitations and involves participants in assessments of their own behaviour and the behaviour of peers. CRM encompasses a wide range of knowledge, skills and attitudes including;

»» »» »»

Situational awareness (SA) Decision-making. Teamwork, including team leadership and communications

Additionally, participants in CRM training learn to understand how cognitive errors occur and are how external stressors such as fatigue, crisis management and work overload can contribute to human error. Training in Human Factors and nontechnical skills, such as teamwork, communication and leadership, have been identified as important contributory factors influencing CPR performance. SITUATIONAL AWARENESS. This can be described as an individual’s awareness of the environment at the moment of an event and the analysis of this to understand how an individual’s actions may impact on future events. This becomes particularly important when many events are happening simultaneously, e.g. at a cardiac arrest. High information input with poor situational awareness may lead to poor decision making and serious consequences. At a cardiac arrest, all those participating will have varying degrees of situational awareness. In a well-functioning team, all members will have a common understanding of current events, or shared situational awareness. It is important that only the relevant information is shared otherwise there is too much distraction or noise. At a cardiac arrest, important situational awareness factors include:


Clinical Connections 11

Decision Making

Leadership

Team Work

»» »» »» »» »» »» »» »» »»

Consideration of the location of the arrest, which can give clues to the cause; Obtaining information from bystanders/ family about the events leading up to the arrest; Confirmation of the diagnosis; Determining who is present - including names, roles, and who is leading; Noting the actions already initiated, e.g medications administered; Communicating with the team, gathering information; Implementing any immediate action necessary, treating reversible causes; Consideration of the likely impact of interventions; Determining the immediate needs.

DECISION MAKING This is defined as the cognitive process of choosing a specific course of action from several alternatives. At a cardiac arrest, the many decisions to be made usually fall to the team leader. The leader will assimilate information from the team members and from personal observation and will use this to determine appropriate interventions. Typical decisions made at a cardiac arrest include: »» »» »»

Diagnosis of the cardiac arrest rhythm; Likely reversible causes of the cardiac arrest; How long to continue resuscitation.

Once a decision has been made, clear unambiguous communication with the team members is essential to ensure that it is implemented. TEAM WORKING, INCLUDING TEAM LEADERSHIP This is one of the most important non-technical skills that contribute to successful management of critical situations. A team is a group of individuals working together with a common goal or purpose. In a team, the members usually have complementary skills and, through coordination of effort, work synergistically. Teams work best when everyone knows each other’s name, when they are doing something they perceive to be important, and when their role is within their experience and competence.

THERE ARE SEVERAL CHARACTERISTICS OF A GOOD RESUSCITATION TEAM MEMBER: »» Competence – has the skills required at a cardiac arrest and performs them to the best of their ability. »» Commitment – strives to achieve the best outcome for the patient. »» Communicates – openly, indicating their findings and actions taken, and be prepared to raise concerns about clinical or safety issues, but also by listening to briefings and instructions from the team leader. »» Supportive – allows others to achieve their best. »» Accountable – for their own and the team’s actions. »» Prepared to admit when help is needed. »» Creative – suggests different ways of interpreting the situation. »» Participates in providing feedback. A team leader provides guidance, direction and instruction to the team members to enable successful completion of their stated objective. They lead by example and integrity. Team leaders need experience not simply seniority. Team leadership can be considered a process; thereby it can become available to everyone with training and not restricted to those with leadership traits. There are several attributes recognisable in good team leaders: »» »» »» »» »» »» »» »»

Knows everyone in the team by name and knows their capability. Accepts the leadership role and is able to delegate tasks appropriately. Is knowledgeable and has sufficient credibility to influence the team through role modelling and professionalism. Stays calm and keeps everyone else focused and controls distractions. Is a good communicator – not just good at giving instructions, but also a good listener and decisive in action. Is empathic towards the whole team. Is assertive and authoritative when appropriate. Shows tolerance towards hesitancy or nervousness in the emergency setting. Has good situational awareness; has the ability to constantly monitor the situation, with an up to date overview, listening and deciding on a course of action.


12 Clinical Connections

During a cardiac arrest, the role of team leader is not always immediately obvious. The leader should state early on that they are assuming the role of team leader. Cardiac Arrest Team leader should: »»

Follow current resuscitation guidelines or explain a reason for any significant deviation from standard protocols.

»»

If they are unsure, he or she should consult with the team or contact Tele medical Support advice and assistance if appropriate.

»»

Play to the strengths of team members and allow them some autonomy if their skills are adequate.

»»

Allocate roles and tasks throughout the resuscitation and be specific. This avoids several people or nobody attempting the task!

»»

Use the two-minute periods of chest compressions to plan tasks and safety aspects of the resuscitation attempt with the team.

»»

At the end of the resuscitation attempt, thank the team and ensure that staff and relatives are being supported. Complete all documentation and ensure an adequate handover.

»»

Debrief the team.

CHALLENGE & RESPONSE CHECKLISTS IN CARDIAC ARREST Effective communication and teamwork is essential for the delivery of high quality, safe patient care at the scene of an OHCA. The complexity of managing an OHCA, coupled with the inherent limitations of human performance, make it critically important that NAS Practitioners have standardised communication tools. Using these tools create an environment in which individuals can speak up and express concerns, and share common ‘‘critical language’’ to alert team members to unsafe situations. Understanding the limitations of the human brain in these stressful environments has led to the development of Challenge & Response Checklists. Originally a concept unique to aviation, they are used to ensure simple cognitive errors do not occur during pre and post flight checks and in the high stress environment of emergency situations. Prehospital emergency care has seen the development of similar checklists for use during the management of Cardiac Arrest, Return of Spontaneous Circulation (ROSC), Post Intubation Care, and the management of major haemorrhage. It is with this in mind that the office of the Medical Directorate has developed a Cardiac Arrest checklist to support practitioners in the care of the OHCA patient. POST RETURN OF SPONTANEOUS CIRCULATION (ROSC) CARE Prehospital return of spontaneous circulation (ROSC) is considered to be one of the strongest predictors of survival to hospital discharge. Upon achieving ROSC in the prehospital setting it is imperative that practitioners provide specific targeted interventions to this highly unstable sub group. The following headings outline the areas that NAS practitioners should focus their care for the Post ROSC Patient. Interventions which address one or more of these components may improve survival and neurological outcome.

TARGETED CARE INTERVENTIONS: Optimization of Ventilation Post ROSC Optimization of Oxygenation Post ROSC Optimization of Hemodynamic Status Post ROSC Optimization of Temperature Post ROSC Control of Seizures Control of Blood Glucose Level Acute Coronary Syndrome (ACS) Management post ROSC Optimisation of Ventilation Post ROSC Patients with decreased level of consciousness, persistent hypoxia or agonal respiratory pattern following ROSC should have their airway managed and positive pressure ventilation instituted. There is a well-documented association between hypocarbia and cerebral ischaemia after cardiac arrest. Ventilation to a ETCO2 of 35-40mmHg is appropriate and should be documented on the PCR. Excessive ventilation should also be avoided because of the potential for reduced cerebral blood flow and the risk of high intrathoracic pressures which can lead to adverse hemodynamic effects during the post arrest phase. Quantitative waveform capnography can be used to regulate and titrate ventilation rates during the post-arrest phase.

Optimisation of Oxygenation Post ROSC

Control of seizures

During the post-cardiac arrest phase inspired oxygen should be titrated to maintain an SpO2 of ≥ 94%. This reduces the risk of oxygen toxicity. The ILCOR guidelines recommend titrating Fi02 down to give oxygen saturations > 94%. Oxygen saturations throughout transport should be documented on the PCR.

There is an increased risk of seizure in patients post cardiac arrest. Any suspected or diagnosed seizures should be treated immediately as per CPG.

Optimisation of Hemodynamic Status Post ROSC Survivors of cardiac arrest frequently experience haemodynamic instability which may persist several hours after ROSC. It is important to maintain myocardial, cerebral and end-organ perfusion during this time. Hypotension, a systolic blood pressure < 90 mmHg should be treated aggressively post ROSC; It has been shown that the administration of fluids and/or vasoactive medications can be used to optimize the patients hemodynamic status. While the optimal blood pressure during the postcardiac arrest phase is not known, the primary objective is adequate systemic perfusion, and a mean arterial pressure of ≥ 65 mmHg should accomplish this Systolic BP >90-100mmhg). Post cardiac arrest ventricular arrhythmias that are symptomatic should be managed with an infusion of the anti-arrhythmic drug that successfully restored a stable rhythm during resuscitation although prophylactic antiarrhythmic drugs have not shown to improve survival.

Optimisation of Temperature Post ROSC Targeted Temperature Management is another key component of Post ROSC care. 2015 ILCOR Guidelines has moved away from aggressive cooling of the patient to a system of targeted temperature management, this process involves maintaining temperature at 32-36 degrees Celsius and avoiding Hyperthermia post arrest. This is achieved in the prehospital setting by passive environmental management.

Control of blood glucose level Hyperglycaemia is common following cardiac arrest. Although there is no proven survival benefit to tight glycaemic control, there is an association between high glucose and poor neurological outcome after cardiac arrest. Check the blood sugar level, and consider treating Hyperglycaemia or Hypoglycaemia.

Acute Coronary Syndrome (ACS) Management Post ROSC Post ROSC patients from undifferentiated cardiac arrests with suspected underlying cardiac aetiology may benefit from being transported directly to a PPCI capable facility. In this cohort of patients the practitioner must also consider the risks associated with potential increased transport times and bypassing non PPCI capable facilities. If a patient requires advanced airway support, continued sedation or management of non-cardiac and traumatic issues they should initially be transported to an appropriate receiving ED for stabilisation prior to Primary Percutaneous coronary Intervention (PPCI) referral. For Post ROSC patients from undifferentiated cardiac arrests with suspected underlying cardiac aetiology or diagnostic ECG identifying a STEMI or new LBBB, the practitioner should contact their regional PPCI Physician on 1800 742222 to discuss appropriate facility decisions.

MEDICO CORK Tales From the Telemedical Support Unit Telemedicine as an Enabler - Dr Jason Van De Velde aggression. Remember our data represents a unique subset of practitioner-patient interactions where the existing CPGs have not fully addressed the needs of either party. If we look at our preliminary data by perceived aetiology, it is very clear that you can’t simply write a CPG for agitation, but rather need to approach agitation from within existing CPGs. We always start with the premise that agitation or aggression is secondary to pain, hypoxia, circulatory compromise, hypoglycaemia or head injury. For example, the head injury CPG might offer an agitated pathway that begins at pain management.

AGITATED PATIENT MANAGEMENT Agitated Patient Management accounts for a quarter of all calls to MEDICO Cork, the HSE’s National 24 hour Emergency Telemedical Support Unit. Agitated Patients present a significant logistical, emotional and resource challenge for prehospital practitioners. They are a subset of patients with a high, particularly in the case of Traumatic Brain Injury, mortality rate. Timely and appropriate intervention in this subset of patients can make a significant difference to long term functional outcome. A great deal of time and thought has gone into several iterations of a PHECC CPG aimed at better streamlining the prehospital practitioners’ approach to agitation. It is a challenging CPG to write, particularly as there are multiple aetiologies for agitation. On our last Audit of 1761 telemedical calls, we found a year-on-year, exponential increase in frequency in practitioners looking for support to manage agitation or

There has been considerable discussion on the telemedical support line around voluntary versus involuntary patients. We have frequently to clarify whether the patient has capacity or not. We are keen to emphasise the need for practitioners to keep themselves up-to-date with the legislation surrounding capacity; and when the Mental Health Act applies and just as importantly, when it does not and the patient is better served under common law. As per the Act, if the patient is deemed to lack capacity through mental illness, and they are refusing the offer of care, then we are advising Physician intervention, i.e. GP to scene or Garda detention under Section 12 of the Act and transport of the patient to an Emergency Department for further assessment of capacity. The “Other” category represents a significant plethora of presentations, including those in which no clear aetiology is evident. At 11% of all agitated patient management calls, it’s no wonder that these patients are so challenging to manage. We are currently undertaking a formal review of Agitated Patient telemedical interactions, with the support of UCC final year Medical Student Jennifer Bevan. This is a significant undertaking, which will see prehospital Irish data presented to further support the evidence based development of PHECC Clinical Practice Guidelines.

Research

Chance, bias andconfounding factors In the last edition we discussed tips on reading a research paper, creating an answerable question using the ‘PICOS’ format to focus our thinking, and the ‘hierarchical evidence pyramid’ that helps us know what types of studies are more reliable. At the top of the evidence pyramid sits systematic reviews and metaanalysis of randomised controlled trials (RCT). The reason these studies are most reliable is because they are designed to minimise the potential for chance, bias and confounding factors influencing the outcome. In this edition we are going to explore these three key concepts so when you are reading papers or thinking about a research project you can ask yourself, am I satisfied that the results I am reading are not influenced by this trifecta. Chance relates to random occurrences. When comparing two treatments, any differences in results may simply reflect the play of chance. The way to avoid being misled by the play of chance in treatment comparisons is to base conclusions on studying sufficiently large numbers of patients and use statistics to measure the potential for chance being the cause of the observed result (p values and confidence intervals are a measure of chance). For example, in a study of 20 patients, 4 out of 10 patients (40%) died after receiving Treatment A compared with 6 out of 10 (60%) similar patients who received Treatment B. Based on these small numbers, would it be reasonable to conclude that Treatment A was better than Treatment B? Probably not. Chance might be the reason that some people got better in one group rather than the other. Or by chance, they may not have been as sick, by chance they may have been a few younger patients in the experimental group, by chance they may have been treated more quickly, by chance they may have been treated by a paramedic who was having a good day etc. If the comparison was repeated in other small groups of patients, the numbers who died in each group might be reversed (6 against 4), or come out the same (5 against 5), or in some other ratio – just by chance. But what would you conclude if exactly the same proportion of patients in each treatment comparison group

(40% and 60%) died after 100 patients had received each of the treatments? Although the risk ratio is exactly the same (40%/60% =0.67) as in the earlier comparison, 40 deaths compared with 60 deaths is a more impressive difference than 4 compared with 6, and less likely to reflect the play of chance. Bias is the systematic distortion of the estimated intervention effect away from the “truth”, caused by inadequacies in the design, conduct, or analysis of a trial and cannot be reduced by sample size. Unlike

...the association between coffee drinking and lung cancer; without considering that often folks drink a coffee and smoke a cigarette the coffee may get blamed for the lung cancer rather than the 20 cigarettes a day smoked with the coffee, the cigarette being the confounding factor

random errors caused by chance, bias will tend to produce results that are consistently wrong in the same direction (i.e. overestimating or underestimating the true value). There are many types of bias – identifying the type of bias isn’t as important as recognising that the study outcomes may have been influenced by bias. For example, selection bias occurs when the selection of patients to enter a study is very different to those not selected. If we were to do a study on a pain killer for use in pre-hospital trauma pain but say the paramedics found it much easier to consent young men and women with certain

DR CONOR DEASY

long bone fractures because they were more articulate and veered away from consenting the elderly with fragility fractures such as neck of femur or distal radius this would represent a selection bias. You might get a hint of this in Figure 1 in the results section of the RCT known as the consort diagram; it describes who was screened for inclusion in a trial and why they were excluded as well as describing those included and the numbers who were lost to follow up. In comparing one treatment with another in a head to head trial, it is very important to figure out whether the patients receiving the experimental treatment were the same as those receiving the standard care – this is always reported in table 1 in the Results section of the RCT. This table demonstrates the patient demographics; their age, sex and key features that may influence the outcome or effect of a treatment. Confounding factors are an error of interpretation. The results of a study may be due to something unmeasured but wrongly attributed to the intervention. The example often quoted in this context is the association between coffee drinking and lung cancer; without considering that often folks drink a coffee and smoke a cigarette the coffee may get blamed for the lung cancer rather than the 20 cigarettes a day smoked with the coffee, the cigarette being the confounding factor. In our own pre-hospital context, again using the example of a study looking at the effect of a new painkiller for injury related pain, if we did not take into account the use of nonpharmacological approaches to pain relief such as kindness, reassurance, splintage in reducing the pain score then we would not get a fair appreciation of the effect of the new drug. That said, kindness and reassurance are extremely difficult to measure in a scientific way – that’s a topic for another day.

ePCR Update The National Ambulance Service (NAS) will be implementing an electronic patient care report (ePCR) nationally over a 12 month period which will commence early in 2017.

Penthrox

(methoxyflurane) By Kieran Henry AP MSc Pain is the most common symptom in the emergency setting and alleviating this remains a challenge for pre-hospital emergency services. Through pharmacological and non-pharmacological methods we can enhance the patient experience by reducing and in some cases eliminating their pain. The greater the arsenal of analgesic options available to the practitioner the better, as some barriers may prevent certain medications being used for particular cases e.g. contraindications, challenges with administration routes etc. Penthrox (methoxyflurane) is an inhaled analgesic option that has just recently arrived in the Irish setting having been well established in the Southern Hemisphere with an estimated 5 million uses over the past 3 decades in Australia. It is a Patient Controlled Analgesia (PCA), which is lightweight, disposable and non-invasive. Penthrox (methoxyflurane) is indicated for the emergency relief of moderate to severe pain in conscious adult patients with trauma and associated pain. It is fast and effective, bringing onset of pain relief within 6-10 inhalations. It is easy to administer, maintenance free and disposable. The feedback so far from those already using it has been very good and we look forward to its roll out within the National Ambulance Service.

This is very positive development for NAS and gives us the ability to examine how well we care for our patients and thereby improve how we care for them. This is part of the NAS commitment to investment within the National Service Plan. It is also a result of a significant collaboration between NAS and the Office of the Chief Information Officer in technology and working together. The implementation of ePCR is dependent on the co-operation and enthusiasm of all NAS staff. This will inevitably present challenges for us all, but we are confident that, with your support and co-operation, this will change how NAS delivers patient care for the better. NAS will transition to an electronic patient record over the next 12 months. NAS practitioners will, once implemented, record patient data electronically using a ruggedized tablet onto an electronic record via a bespoke software platform. The existing paper PCRs that NAS staff are familiar with will no longer be used; instead patient data will be recorded electronically. This represents a significant change in how NAS conducts it’s business. The following information is designed to inform NAS colleagues about how ePCR will function. Why are NAS implementing an electronic patient care report? NAS have over 300,000 patient contacts annually. Our ability to do comprehensive data analysis or clinical audit from 300,000 paper records (including collection from 102 locations) is limited. A modern ambulance service must be able to analyse clinical performance – ePCR will give us the ability to do this. Patient data will be captured electronically in a standardised manner – the dataset significantly exceeds that which is currently collected on the paper form. NAS will capture much more accurate patient information such as presenting complaint, past history, medications, clinical signs, mechanism of injury, presumptive diagnosis and treatments administered prehospital. This will mean that a more complete picture of each individual

patient’s acute episode can be provided to the receiving ED by NAS. It also will allow NAS to have a very detailed overview of trends in patient demographics, patient presentations as well as how well NAS assesses and treats patients. How will ePCR work? Each NAS vehicle will have a Panasonic Toughbook with the ePCR software provided. The ePCR product is called Medusa Siren (see www.medusamedical.com). NAS practitioners will input clinical data to the ePCR application electronically (drop-down menus, tick-boxes and free text). This will create an electronic patient record for each patient. The information recorded will incorporate that currently recorded on the paper PCR and we are basing the data fields in the ePCR on the PHECC dataset. The patient demographics, dispatch code, allocation and mobile times etc will be prepopulated on the electronic record by an electronic push from CAD, so some information currently being recorded manually will be automatically entered on the ePCR record. The ePCR and the LIFEPAK® 15 monitor/defibrillator can communicate electronically via Bluetooth connection. This means that vital signs recorded on the LP15 and/or a 12 lead ECG can be added to the electronic record. Has there been any staff input into the ePCR project? Yes. The ePCR Project Team has had two NAS staff members, nominated by IARC, as team members. They have provided very valuable input into all aspects of the project design and proposed implementation. A number of other NAS staff members have also been involved in subgroups of the main project team, and NAS staff members in the first implementation area, the South, have also contributed. How will NAS benefit from ePCR? NAS will be able to do the following »»

Systematic clinical audit (eg STEMI care, pain management etc)

»»

Quality assurance (compliance with clinical practice guidelines, national standards etc)

How will practitioners benefit from ePCR? In many ways.

comes with a protective case with a glove like attachment that allows users to hold the unit comfortably while inputting patient information. The unit has a touchscreen which will allow input via screen interaction, a traditional keyboard to assist with freetext input, as well as a stylus. A rigorous process to identify the optimum positioning in the vehicle has been carried out. This process took note of considerations from staff representatives, tablet providers, vehicle manufacturers and others as well as an independent health and safety expert and an assessment by an ergonomist.

Practitioners will be able to access all records on which they are part of the attending crew. When Paramedic and Advanced Paramedic CPD come on stream from PHECC, this will be useful for individual practitioners in fulfilling their CPD requirements to PHECC. We are also exploring the opportunity of putting additional resources on the tablet – for example CPGs, medication formulary, and other clinical resources that may assist practitioners on calls. NAS will be able to analyse how the service delivers patient care which will allow us to identify clinical initiatives that should be implemented, clinical issues that need greater emphasis in training, upskilling opportunities, or patient pathways that can be improved upon or updated.

Will ED staff still get a paper record at patient handover?

How will ePCR work in practice?

NAS will be able to provide much more comprehensive data to EDs – for example patterns of ambulance borne patient attendance, data on particular clinical issues of interest, quicker and more detailed responses to queries on individual patient issues that may arise.

The ePCR unit is a tablet which has a detachable keyboard. A docking unit (which also charges the unit) will be placed in the back of the vehicle, and the unit will stay in this docking unit while not in use (allowing the battery to remain charged). The unit also

Yes. As part of the project implementation NAS will install printers in each ambulance, allowing the crew to print the electronic record for the purposes of patient handover prior to entering the ED. For some patients, clinical care will preclude ePCR completion prior to arrival at ED – in this instance clinical handover will happen, and the ePCR can be completed and handed over afterwards. Patient care will always be the priority. There will also be a web - viewer installed on PCs in each ED, allowing staff to view the record electronically. How will EDs benefit from this?

Will there be challenges or issues with this change? Inevitably. This is a major change in how NAS does its business, and there will naturally be issues that arise as we implement the product. Each area will have designated ambulance managers and supervisors as points of contact for staff with questions or suggestions on the roll-out as it happens. We also hope to identify ePCR “champions” in stations that are implementing the ePCR, who will provide peer assistance if required. Where will the ePCR be implemented first? ePCR will be implemented first in Cork city and then to the greater SouthWest, followed by the South – East. ePCR will then be phased in nationally over approximately 12 months. The roll-out is linked to the Mobile Data Terminal roll-out, as the two systems are linked. Will we still get the old paper PCR? The intention is that ePCR will be the default clinical record for NAS from 2017 onwards. We will still carry paper PCRs as a resilience measure (eg technical issue where ePCR solution fails), but use of paper PCRs should be very small. In advance of the implementation, we are happy to be contacted with any queries or observations.

‘Not Just Little Adults’ The Paediatric Trauma Patient

DAVID HENNELLY, AP MSc Clinical Development Manager

Ask any medic to describe their top three “Out of their comfort zone moments” and I can pretty much guarantee at least one will involve a paediatric patient. As paediatric trauma is relatively uncommon (thankfully), contributing to circa 6% of all TARN eligible major trauma patients, it requires regular case reflection and training to ensure that when the call comes that we are adequately prepared to manage the unique needs of the paediatric trauma patient. This article describes how a paediatric physiology differs from that of the adult patient. We will review unique aspects of paediatric trauma patients including airway, respiratory and cardiovascular response to haemorrhage, spinal injuries, traumatic brain injuries, thoracic injuries and blunt abdominal trauma. Understanding the many differences between adult and paediatric trauma patient and having a systematic approach is critical to providing excellent care, preventing secondary insult and avoiding oversight of potentially significant injuries.

A

Airway

Airway compromise, respiratory reserves, hypoxia and inadequate ventilation are the most common causes of paediatric cardiopulmonary arrest following trauma, therefore, efficient and effective airway management is a critical aspect for paediatric trauma. The unique features of infant and paediatric airway anatomy and respiratory physiology make airway management one of the most challenging components of paediatric trauma care.

Infants are nose breathers »»

Trachea is more cartilaginous and soft »»

The cartilaginous nature of the paediatric airway makes it more prone to collapse and obstruction than the adult airway if the child is not positioned appropriately.

»»

The tonsils in toddlers and young children may be enlarged, contributing to airway obstruction and making insertion of an endotracheal tube difficult.

Paediatric airway is smaller »»

In the small airway, there is greater risk of airway obstruction from small foreign bodies.

»»

Children with loose deciduous teeth may have one dislodged into the airway.

»»

Small amounts of swelling of the smaller paediatric airway will result in a relatively greater reduction in airway diameter than would occur in the larger airway of the adult.

Larynx is higher and more anterior and the epiglottis is larger »»

The larynx sits at the level of the 2nd 3rd cervical vertebrae in the young child, compared with the 6th -7th cervical vertebrae in the adult.

»»

The positioning of the larynx makes its visualisation in the paediatric airway more difficult than in the adult.

»»

The epiglottis of the young child larger and less rigid than that in an adult. This makes the technique of tracheal intubation more difficult.

Relatively larger tongue and smaller oral cavity »»

The relatively larger tongue and smaller oral cavity means that, in the child, the tongue is more likely to obstruct the airway than in the adult. This makes it essential that there is correct positioning of the head jaw to open the airway.

Infants have a relatively larger occiput »»

»»

The large occiput of the infant flexes the head forward when he/ she is placed prone on a flat surface. This is important in airwayopening manoeuvres and cervical spine immobilisation. Simple procedures such as positioning a small blanket roll on the spinal board / vacuum mattress in line with the scapula prior to moving the patient can greatly assist with ongoing airway management. Care must be taken not to hyper-extend the neck, as this may result in airway obstruction or spinal cord damage in the event of a cervical spine fracture.

In the first 4-6 months of age infants breathe exclusively through the nose, and will experience respiratory distress if the nose is blocked. Care must be taken to ensure that the nares are patent in cases of infant trauma.

Cricoid ring is the narrowest point in the airway and the trachea is short »»

This also has implications for endotracheal intubation.

»»

The clinician is not able to confirm endotracheal tube size by viewing the tube pass through the narrowest section of the airway, as in adult intubation.

»»

The paediatric trachea is comparatively shorter than that of the adult, which increases the risk of dislodgement of the endotracheal tube.

Breathing

often see nasogastric tubes inserted in the ED to decompress the stomach, to stop it impinging on diaphragmatic excursion.

Thoracic Injuries are the second leading traumatic cause of death in children; Chest wall more compliant. »»

The ribs and sternum are not fully ossified until late in adolescence so the chest wall provides less protection to underlying vital structures, thus a significant amount of energy is transferred to the lungs, heart and great vessels.

Increased mobility of the mediastinal structure. »»

The increased mobility of the mediastinum increases the likelihood that the injured child may develop a tension pneumothorax from a simple pneumothorax, or transect a small mediastinal vessel as the mediastinum shifts.

Diaphragmatic breathing »»

In infancy, the diaphragm is the most significant respiratory muscle. This is why we

»»

The greater compliance of the chest wall in infants and young children also explains the significant intercostal retraction that occurs in children when the airway is obstructed, or there is a decrease in lung compliance.

Respiratory and heart rates varies with age and physiological insult »»

Young children have significantly higher metabolic rates than adults, and therefore have a higher oxygen demand, which in turn results in higher respiratory rates. Respiratory rates will often be the first significant sign of a change in the paediatric patient’s condition.

»»

Heart rate will be influenced by respiratory insufficiency. Infants become bradycardic when hypoxic.

C

Circulation

D

Disability

Blood volume is relatively larger, but absolute volume is smaller 80-90ml/kg in the paediatric patient vs 65-70ml/kg in the adult patient. Relatively small volumes of blood will constitute significant blood loss in small children, ie: a 100ml haemorrhage experienced by a 5 kg child represents the loss of approximately 10% of their total blood volume. Monitor and record all blood loss, including amounts that would be insignificant in the adult patient.

Expose & Examine

»»

Furthermore, infants and small children must increase their heart rates to increase stroke volume and improve cardiac output. Therefore, any interventions or medications that decrease heart rate may cause a rapid and detrimental loss of perfusion.

Fluid Replacement

»»

Fluids should be administered at 10ml/kg as per CPG but Practitioners should remain cautious to avoid clot disruption in patients with active internal hemorrhage.

Cardiovascular Response to Haemorrhage Children are better able to maintain relatively normal blood pressure despite significant blood loss, compared to adults. Studies have shown that paediatric patients can maintain a

Traumatic brain injury is the leading cause of death in paediatric trauma patients. While the best management is prevention, once the injury has occurred, it is critical to prevent secondary insult to the brain from hypoxemia and hypotension.

»»

The cranial sutures do not fuse until the head has reached adult size, providing some limited protection to the brain tissue by allowing limited expansion.

Open sutures, presence of fontanelle

Thinner cranial bones and head relatively larger

»»

»»

The thinner cranial bones of children do not afford as much protection to the brain tissue as the thicker bones of the adult skull.

»»

The proportions of head to body in the infant and small child are significantly larger than in the adult. This will result in greater heat loss from the surface of the exposed head.

»»

The size of the head relative to the body also results in a higher centre of gravity, which in turn contributes to a higher incidence of head trauma in children.

The anterior fontanelle can be palpated in most children up to the age of 12 - 18 months before it closes permanently, and the posterior fontanelle may be palpated in some children up to the age of 2 months. It is important to recognise a bulging or sunken fontanelle and the relevance of these findings. In the trauma setting, the bulging fontanelle will suggest a rise in intracranial pressure, which may be a result of intracranial bleeding. The sunken fontanelle may suggest significant intravascular losses.

The smaller the child, the greater the likelihood that a single impact will injure multiple organ systems. It is vital to expose and assess the patient appropriately to assess for occult injuries. Blunt abdominal trauma is the third most common cause of paediatric trauma deaths, but is the most common unrecognized fatal injury. Many serious abdominal injuries have non-specific or subtle external signs, so a systematic approach is important to avoid a missed diagnosis. Splenic and hepatic injuries are the most common followed by renal, small bowel and pancreatic injuries. Children have very compliant chest and abdominal walls, and a relatively larger volume of viscera with less fat within a smaller diameter. As a result, the liver and spleen are less protected by the rib cage, placing them at increased risk of injury during blunt trauma. Concerning exam findings include abdominal wall abrasions or bruising, seat-belt marks, tenderness or rigidity, distension, referred

shoulder pain from diaphragmatic irritation, and emesis. Abdominal wall bruising is a significant finding as one study of restrained children in RTC’s found that those with a “seatbelt sign” were 232 times more likely to have intra-abdominal injuries than those without. Spinal injuries are relatively uncommon in the paediatric trauma patient, and make up <2% of all paediatric trauma patients. About one half of patients with vertebral fractures have no neurologic findings. Conversely, some patients have spinal cord injuries without radiographic abnormality (SCIWORA), where the normal laxity of the soft tissues of the child’s spinal column leads to damage of the spinal cord without fracture or ligamentous injury. In contrast to adults who are more likely to suffer lower c-spine injuries, most spinal injuries in young children involve the upper c-spine due to their relatively larger heads that create a fulcrum-like effect on the upper c-spine region.

Due to the lack of subcutaneous fatty tissue and larger surface-area to body-mass ratio paediatric patients are prone to becoming rapidly hypothermic, although thorough assessment is vital, it is imperative that

Infants have relatively small glycogen stores when compared with those of an adult. For this reason, it is essential to monitor blood sugar levels in sick and injured infants.
