The performance of life-saving procedures by prehospital care personnel was reviewed in the cases of 114 pulseless, nonbreathing pediatric patients. Children 18 months to 18 years of age had a significantly greater chance of having prehospital endotracheal intubation and vascular access established compared to children younger than 18 months of age. For all patients, witnessed arrest and initial rhythm of ventricular fibrillation were significantly associated with survival. In the younger children, endotracheal intubation also was associated significantly with survival. Nine (8%) patients survived, and only three of the survivors were without neurologic sequelae. The number of neurologically intact survivors was too small to show a statistically significant association with these factors. © 1987.
