The association between chest compression (CC) pause duration and pediatric in-hospital cardiac arrest survival outcomes is unknown. The American Heart Association has recommended minimizing pauses in CC in children to <10 seconds, without supportive evidence. We hypothesized that longer maximum CC pause durations are associated with worse survival and neurologicalal outcomes.
METHODS
In this cohort study of index pediatric in-hospital cardiac arrests reported in pediRES-Q (Quality of Pediatric Resuscitation in a Multicenter Collaborative) from July of 2015 through December of 2021, we analyzed the association in 5-second increments of the longest CC pause duration for each event with survival and favorable neurological outcome (Pediatric Cerebral Performance Category ≤3 or no change from baseline). Secondary exposures included having any pause >10 seconds or >20 seconds and number of pauses >10 seconds and >20 seconds per 2 minutes.
RESULTS
We identified 562 index in-hospital cardiac arrests (median [Q1, Q3] age 2.9 years [0.6, 10.0], 43% female, 13% shockable rhythm). Median length of the longest CC pause for each event was 29.8 seconds (11.5, 63.1). After adjustment for confounders, each 5-second increment in the longest CC pause duration was associated with a 3% lower relative risk of survival with favorable neurological outcome (absolute risk reduction, 0.97 [95% CI, 0.95-0.99]; P=0.02). Longest CC pause duration was also associated with survival to hospital discharge (absolute risk reduction, 0.98 [95% CI, 0.96-0.99]; P=0.01) and return of spontaneous circulation (absolute risk reduction, 0.93 [95% CI, 0.91-0.94]; P<0.001). Secondary outcomes of any pause >10 seconds or >20 seconds and number of CC pauses >10 seconds and >20 seconds were each significantly associated with lower absolute risk reduction of return of spontaneous circulation, but not survival or neurological outcomes.
CONCLUSIONS
Each 5-second increment in longest CC pause duration during pediatric in-hospital cardiac arrest was associated with lower chance of survival with favorable neurological outcome, survival to hospital discharge, and return of spontaneous circulation. Any CC pause >10 seconds or >20 seconds and number of pauses >10 seconds and >20 seconds were significantly associated with lower adjusted probability of return of spontaneous circulation, but not survival or neurological outcomes.
