Early semi-automatic defibrillation Pediatric Basic Life Support - Early Defibrillation

PBLSD course

31


Semi-automatic external defibrillator (AED) Rational: • Primary cardiac arrest in children is less common than in adults • Ventricular fibrillation is rare, but under diagnosed in children compared to adults (7-15% of cases of cardiopulmonary arrest) • Among the most frequent causes of shockable rhythms: congenital heart disease, long QT syndrome, drug intoxication, hypothermia, trauma • Early defibrillation improves the outcome of these children

PBLSD course

32


Semi-automatic external defibrillator (AED) Rational: • In pediatric studies, shockable cardiac arrest treated with early defibrillation demonstrates good survival • The AEDs tested in adult and pediatric arrhythmia studies have shown high accuracy in rhythm analysis (near 100% specificity)

PBLSD course

33

Duration of resuscitation maneuvers Consider suspending CPR after 15-20 minutes of resuscitation with no clinical response Assess: • • • •

Reasons for arrest Pre-existing clinical conditions Untreated duration arrest (“no flow time”) Rescue intervention times (basic/advanced) and CPR effectiveness (“low flow time”) • Availability of specific treatment for particular causes (eg. toxics) Decision manager: team leader Important: operator debriefing immediately after the event PBLSD course

46


Parental presence during CPR Parents want to be present during CPR For the parents: • Allows them to see that everything possible has been done In case of decease: • Improves grieving process • Reduces anxiety and depression For the health personnel: • Stimulates appropriate professional behavior • Helps to see the child as a whole

2010 guidelines PEDIATRIC BLS • Prevention of arrest in childhood • ABC or CAB? • CPR quality

PBLSD course

56


Prevention of arrest FIRST LINK TO THE SURVIVAL CHAIN: unchanged since 2005 Main causes of death in childhood: •

In infants: congenital malformations, complications of prematurity, SIDS

In children > 1 years: traumas

Prevention: • • •

prevention of trauma and violence against children information campaigns on SIDS recognition and early treatment of the child’s hemodynamic instability

PBLSD course

57


ABC or CAB? The CAB sequence is also recommended for infants and children (except newborns) to streamline CPR training with the hope that more cardiac arrest victims will receive cardiopulmonary resuscitation

Motivations: •

Positioning the head and having to initiate ventilations delays the onset of compressions

It is not known whether starting ventilations or compressions makes a difference in survival

Starting with compressions (CAB) instead of ventilations (ABC) leads to a delay in ventilations of only about 18 seconds (if 1 rescuer only) or even less (if 2 rescuers)

PBLSD course

58


CPR quality

PBLSD course

Further deemphasis on wrist relief

High quality chest compressions

Depth of compressions

Frequency

Complete chest relaxation after each compression

Minimize interruptions in compressions

Avoid hyperventilation

59


Chest compressions

• • • • •

PBLSD course

Compress the chest “hard and fast” at the rate of at least 100/m’ Lower the chest at least 1/3 of the anteroposterior diameter (4 cm in infants and 5 cm in children) Allow the chest to rise completely Minimize interruptions in compressions Avoid hyperventilation!

60


Ventilations during CPR

• • •

Avoid hyperventialtion Deliver 1 breath over 1 second, controlling chest rise The routine use of cricoid pressure is no longer recommended

• • • •

PBLSD course

1 rescuer: 30:2 2 rescuers: 15:2 Respiratory arrest: 12-20 ventilations/m’ Intubated child: 8-10 ventilations/m’ (1 ogni 6-8”)

61


Defibrillation with AED even in infants

PBLSD course

Prefer a manual defibrillator if possible

If not available, use pediatric or attenuator AEDs

If neither pediatric AEDs nor attenuator paddles are available, use adult AEDs and adult paddles

62


Cardiac arrest algorithm

PBLSD course

63


The novelties of the cardiac arrest algorithm

PBLSD course

Defibrillation energies

ROSC: • Pulse • Pressure wave on intra-arterial monitoring • Elevation of PETCO2 on capnography/capnometry

Different algorithm for neonatal resuscitation

Advanced airway: intubation or supraglottic garrison

Nothing new compared to 2005 regarding the sequence

64


Defibrillation

• • • • •

PBLSD course

Dimensions of the plates Interface Position Energy Automatic defibrillators

65


Dimensions of the plates

• Adults (8-10 cm for b > 10 kg) • Infant size (< 10 kg) • Located below the adult ones in the manual defs • There are also “hands free” stickers • Same effectiveness • If possible, leave 3 cm between the plates or electrodes Unchanged since 2005

PBLSD course

66


Defibrillation energy

• The minimum effective dose and the upper safe limit for infants and children are not known • Biphasic shock as effective as mono-phasic and less harmful • It is acceptable to use an initial dose between 2 and 4 J/Kg (Class IIa. LOE C). For educational purposes it can be simplified to an initial dose of 2 J/Kg (Class IIb, LOE C). In refractory VF, a dose of 4 J/Kg (Class IIa, LOE C) which in subsequent shocks can be further increased without however exceeding 10J/Kg or the maximum adult dose (Class IIb, LOE C)

PBLSD course

67


Airway management: bag-mask ventilation •

Ventilation as effective and safe as intubation for short periods during pre-hospital resuscitation (class IIa, LOE B)

Use sufficient volume to give visible chest lift (class I, LOE C), avoid hyperventilation during arrest (class III, LOE C)

Cricoid pressure if a third rescuer is present, avoid excessive pressure on the trachea (class III,LOE B)

PBLSD course

68


Airway management •

Pediatric oropharyngeal and nasopharyngeal cannula: assicurarsi di avere scelto la misura corretta

AML: “when bag-mask ventilation is not effective and when tracheal intubation is not possible, AML is acceptable when used by experienced providers, to ensure a patent airway and ventilate” (class IIa, LOE C)

However, AML is associated with a higher incidence of complications in young children than in older children or adults

There are insufficient clinical studies to recommend other supraglottic devices in children other than AML
