Introduction: To describe the epidemiology of paediatric out-of-hospital cardiac arrest in Madrid and survival to hospital arrival.

Methods: Retrospective observational study between January2002 and December 2003, of 582 CPR attempts.

Results: There were 18 paediatric cases (3.1% of total cardiacarrests). Six (33.3%) had ROSC on hospital arrival. 66.7% were male.76.5% had bradycardia or asystole and 23.5% VF/pulseless VT. Sur-vival was 75% for VF/pulseless VT and 23.1% for bradycardia orasystole. In 22.2% of case clinical staff were present and in 33.3%there were no witnesses. The survival when sanitary staff witnessedthe cardiac arrest was 50%, and for the group in which not-sanitarypersons were present were less than 25% and when there was nowitness was 33%. Survival if resuscitation started before the arrivalof the emergency unit was 38.5% compared with 0% if this did notoccur. Most cardiac arrests in our series were caused by trauma.

Conclusion: Out-of-hospital cardiac arrest is less common inchildren compared to adults. The overall survival rate is betterin children than adults. When CPR was not started before thearrival of the emergency services there were no survivors. If cardiacarrest occurred in the presence of the emergency service, survivalimproved. Survival was best in trauma patients.

Introduction: The current guidelines on neonatal and paedi-atric resuscitation recommend a compression depth of 1/3 to 1/2of the anterior—posterior chest diameter (APD). However, therehas been little evidence supporting such manoeuvre. This studywas conducted to assess the actual depth of chest compressions inneonatal and paediatric populations if current guidelines are strictlyfollowed.

Methods: Chest computerised tomography (CT) of 12 neonatal(<1 year of age) and 11 paediatric (1—8 years of age) patients werereviewed. Measurements of AP diameter of chest CT scans (APD)were taken from the skin anteriorly perpendicularly to the skinon the posterior thorax at either the inter-nipple line (INL) or themiddle of the lower half of sternum (LS).

Results: In the neonatal group, there were 10 male infants withthe mean age was 0.39 years. In the paediatric group, there were7 male children with a mean age of 4.36 years. Our measurementsshowed that compression depth would be equal to or greater thanthe recommended depth for adult chest compression (3.8—5.1 cm)if current guidelines are followed. No difference in compressiondepth was found whether distance was measured at INL or LS (seeTable 1).

Conclusions: Measurements made from radiological assessmentsf the neonatal and paediatric chest indicate similar or higherepths of compression for neonatal and paediatric populations whenompared with the adult populations according to current guide-ines. More evidence is needed to provide a more realistic guideo the depth of chest compression in the neonatal and paediatricopulations.

Introduction: Approximately 80% of survivors of cardiac arrestre comatose following return of spontaneous circulation and maye eligible for ICU admission. This study sought to establish long-erm outcomes (and predictors of outcome) in comatose survivorsf cardiac arrest admitted to ICU.

Methods: Adult patients, admitted to ICU between 1996 and004, who had CPR within 24 h prior to ICU admission, were identi-ed from the ICU database (ICNARC). Demographic and physiologicalarameters within 24 h of admission were collected. Organ failureas defined by SOFA score. Short-term (survival) and long-termutcomes (Karnofsky Performance Scores (KPS)) were recorded.ultiple logistic regression was used to identify factors associatedith poor outcome.

Results: 424 cardiac arrest survivors were admitted to ICU outf 5298 total admissions (8%). ICU and hospital survival rates was1% (n = 174) and 25% (n = 107), respectively, compared to survivalates of 73% and 64% in all patients (p < 0.001). Organ failure wasommon after admission (respiratory 54%; CVS 39%; renal 16%).5% had hyperglycaemia (BM > 11.1). Patients with ≥2 organ fail-re had a sixfold increase in hospital mortality (OR 6.8; 95% CI.4—10). APACHE 2, age; gender did not predict outcome. Mostatients discharged from hospital were alive at 1 (80%) and 2 years69%). The working age group (<65 years) comprised 18 patients,edian age 44.5 years (IQR 30—51). 1/3 were unable to return toork. Median KPS was 75. The non-working age group, (≥65 years)

ncluded 16 patients, median age 69 years (IQR 65—76). Median KPSas 95.

Discussion: Patients who develop multi-organ failure within 24 hf admission to ICU are at increased risk of death. Most patientshat survive to hospital discharge are alive at 1 year. There is highorbidity in young survivors and a third were unable to return toork.
