(HealthDay News) — Delay in epinephrine administration is associated with worse outcomes for children with in-hospital cardiac arrest with an initial nonshockable rhythm, according to a study published in the August 25 issue of the Journal of the American Medical Association.
Lars W. Andersen, MD, from the Beth Israel Deaconess Medical Center in Boston, and colleagues analyzed data from the Get With the Guidelines-Resuscitation registry for pediatric patients with an in-hospital cardiac arrest and an initial nonshockable rhythm who received one or more doses of epinephrine. The final cohort included 1,558 patients (median age, 9 months).
The researchers found that 31.3% of patients survived to hospital discharge. In multivariable analysis, longer time to epinephrine administration correlated with lower risk of survival to discharge; decreased risk of return of spontaneous circulation (ROSC); reduced survival at 24 hours; and reduced risk of survival with favorable neurologic outcome (multivariable-adjusted risk ratio per minute delay, 0.95, 0.97, 0.97, and 0.95, respectively). The risk of in-hospital survival to discharge was significantly lower for patients with time to epinephrine administration of more than five minutes vs. five minutes or less (multivariable-adjusted risk ratio, 0.75).
“Among children with in-hospital cardiac arrest with an initial nonshockable rhythm who received epinephrine, delay in administration of epinephrine was associated with decreased chance of survival to hospital discharge, ROSC, 24-hour survival, and survival to hospital discharge with a favorable neurological outcome,” the authors write.
