Probability of survival based on etiology of cardiopulmonary arrest in pediatric patients.

OBJECTIVE To aggregate data across institutions to identify, characterize, and differentiate potential survivors from nonsurvivors based on etiology of event. AIM To evaluate the association of the cardiopulmonary resuscitation (CPR) duration and probability of survival (Ps), stratified by etiology of arrest. BACKGROUND In-hospital cardiac arrests occur in 2-6% of pediatric patients with poor survival rates resulting in significant expenditures of time and resources. METHODS Retrospective data from six pediatric hospitals on patients suffering from pulseless cardiac arrests receiving CPR for over one minute were analyzed. Data included demographics, reason for code, precardiac arrest diagnosis, devices and treatment, management strategies during cardiac arrest, compression duration, outcome at hospital discharge, and neurologic outcome of survivors at hospital discharge. Results of logistic regression analysis generated predicated probabilities of survival for duration of compression. Patients were stratified by cardiac-induced cardiac arrests (CICA) and respiratory-induced cardiac arrest (RICA). RESULTS A total of 257 patients were included, and 27% of CICA and 35% of RICA patients survived to hospital discharge. Ps was initially lower for the CICA patients (Ps at 1 min = 29%) and remained constant (Ps at 60 min = 25%). RICA patients'Ps was higher initially (Ps at 1 min = 62%) but demonstrated a dramatic drop within the first 60 min of CPR (Ps at 60 min = 0.2%). CONCLUSIONS Probability of survival curves based on duration of CPR was statistically significantly different for CICA patients compared to RICA patients.
