Outcomes After In-Hospital Pediatric Recurrent Cardiac Arrests.

OBJECTIVES

The objective of this study is to determine outcomes of recurrent cardiac arrest events in the general pediatric inpatient population.

DESIGN

Retrospective cohort study of inpatients in a single institution.

SETTING

A tertiary care free-standing children's hospital.

PATIENTS

All patients less than 18 years old at Seattle Children's Hospital with recurrent cardiac arrest events occurring from January 1, 2010, to March 1, 2018, were included.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Overall survival to hospital discharge was 50% and all survivors had a good neurologic outcome, defined as Pediatric Cerebral Performance Category of 3 or less, or unchanged from baseline. Survival among patients who received extracorporeal life support was 43% and among those who received extracorporeal cardiopulmonary resuscitation, 33%. Initial arrest factors associated with survival included initial rhythm of ventricular tachycardia or ventricular fibrillation, shorter duration of cardiopulmonary resuscitation, and absence of multiple organ dysfunction. Additionally, nonsurvivors had more severe metabolic acidosis in the prearrest and postarrest period.

CONCLUSIONS

Survival after pediatric in-hospital recurrent cardiac arrest is higher than previously reported. There is also evidence that initial rhythm other than ventricular tachycardia/ventricular fibrillation and longer duration of cardiopulmonary resuscitation as well as multiple organ dysfunction and more severe lactic acidosis in the peri-arrest period are associated with poor outcomes.
