Medical Emergency/Rapid Response Team/Early Warning Scores ILCOR Pediatric RRT or MET systems may be beneficial to reduce the risk of respiratory and/or cardiac arrest in hospitalized pediatric patients ARC and NZRC All institutions should have a system which enables staff at the bedside to quickly summon expert help to assist in the management of serious-illness. Examples of such systems are medical emergency team (MET) or rapid response team (RRT) systems

STARTING CPR If the victim is unresponsive and not breathing normally (ILCOR and there are no signs of life) and if cannot palpate a pulse within 10 seconds with certainty, start CPR
PULSE PALPATION ( 2009; 80: 61. 2010; 81: 671) Accuracy 78% - all doctors and nurses Sensitivity 86% (diagnose CA correctly BUT fail to diagnose CA 14%) Specificity 64% (exclude CA correctly BUT diagnose CA incorrectly 36%) Average 15 seconds to exclude CA when truly absent Average 30 seconds to confirm CA when truly present Experienced doctors correctly diagnose CA within 10 seconds

COMPRESSION : VENTILATION RATIO 15:2 Why not 30:2 ratio for infants and children? JT 2011
Why not 30:2 for paediatrics? No human evidence Consensus with adult scientists NOT achieved. (Paediatricians not persuaded by animal cardiac arrest studies, mannekin studies and computer simulations) Rationale conjecture: Paediatric ventilation requirement greater than adult Hypoxic arrest, not sudden arrhythmia arrest, more common in paediatric practice In out-of-hospital paediatric cardiac arrest (Kitamura et al., Lancet 2010; 375: 1347) Survival from asphyxial cause better (7.2%) with standard CPR (7.2%) vs compression-only CPR (1.6%) vs no CPR (1.5%) Survival from cardiac cause same with standard CPR (9.9%) vs compression-only CPR (8.9%) vs no CPR (4.1%) 15:2 previously used for children (one-person rescue) JT 2011
Compression-ventilation ratios for infants JT 2011
Compression : ventilation ratio for infants (Term infants out of delivery area within first month) At birth 3:1 ILCOR In non-neonatal setting (eg ED, PICU, prehospital) or with cardiac aetiology regardless of location: No ETT prefer 15:2 over 3:1 ETT continuous compressions no pauses for ventilations (15:2) For use of training use what is commonly used in your environment ARC & NZRC In ED, PICU, wards, prehospital setting use 15:2 With exception of newborns, with cardiac aetiology regardless of location: No ETT - 15:2 ETT - continuous compressions no pauses for ventilation 10/min
Ventilations after intubation ILCOR reduce 2010 AHA 8-10/min (no circ) 12-20/min (circ) ARC & NZRC 10/min ERC 10-12/min JT 2011
Compression : Ventilation ratio after intubation 10:1 JT 2011

Monitoring exhaled CO 2 JT 2011
1. To detect non-tracheal intubation (standard of care) 2. Assess effectiveness of CPR JT 2011
Monitoring end-tidal CO2 (PetCO 2 ) ILCOR May guide effectiveness of chest compressions. If PetCO 2 is < 15 mmhg, improve chest compression and reduce ventilation ARC & NZRC Low PetCO 2 may be due to excessive positive pressure ventilation or inadequate chest compressions or both Cannot yet identify threshold to stop CPR
Quantifying the effectiveness of CCs End tidal C02 will rise as pulmonary blood flow and overall cardiac output rises, assuming that the amount of ventilation (tidal volume and rate) does not change Jin, CCM, 2000
Assessing effectiveness of CPR No ROSC low end-tidal CO 2 ROSC normal end-tidal CO 2 Krep H, Mamier M, Breil M, et al.. 2007;73(1):86. JT 2011
Partial pressure of end-tidal carbon dioxide successfully predicts cardiopulmonary resuscitation in the field: a prospective observational study. Kolar et al., Crit Care 2008;!2: R115 737 intubated cases out-of-hospital cardiac arrest After 20 minutes of CPR: 402 cases of ROSC when PetCO 2 mean 33+/-9 mmhg 335 cases of non-rosc when PetCO 2 mean 7+/-2 mmhg PetCO 2 <14 mmhg reliably predicts (100%) non-rosc PetCO 2 >14 mmhg reliably predicts (100%) ROSC
Oxygen ILCOR Cannot specify oxygen concentration during resuscitation After resuscitation, titrate oxygen concentration to limit hyperoxemia ARC & NZRC Use 100% oxygen initially for resuscitation After resuscitation reduce to yield PaO2 80-100 mmhg
Hypothermia ILCOR Hypothermia (32-34 degrees) may be considered for those remaining comatose after resuscitation ARC & NZRC It is acceptable to induce hypothermia (32-34 degrees) within 6 hours and maintain up to 72 hours in those remaining comatose after resuscitation

... the debate will continue, especially when data is lacking, after all It s not necessary to understand things in order to argue about them Il n est pas nécessaire de tenir les choses pour en raisonner (Pierre Beaumarchais. Le Barbier de Séville)
