Abstract

Introduction:

The concept of compressions only cardiopulmonary resuscitation (CO-CPR) evolved from a perception that lay rescuers may be less likely to perform mouth-to-mouth ventilations during an emergency. This study hopes to describe the efficacy of bystander compressions and ventilations cardiopulmonary resuscitation (CV-CPR) in cardiac arrest following drowning.

Hypothesis/Problem:

The aim of this investigation is to test the hypothesis that bystander cardiopulmonary resuscitation (CPR) utilizing compressions and ventilations results in improved survival for cases of cardiac arrest following drowning compared to CPR involving compressions only.

Methods:

The Cardiac Arrest Registry for Enhanced Survival (CARES) was queried for patients who suffered cardiac arrest following drowning from January 1, 2013 through December 31, 2017, and in whom data were available on type of bystander CPR delivered (ie, CV-CPR CO-CPR). The primary outcome of interest was neurologically favorable survival, as defined by cerebral performance category (CPC).

Results:

Neurologically favorable survival was statistically significantly associated with CV-CPR in pediatric patients aged five to 15 years (aOR = 2.68; 95% CI, 1.10–6.77; P = .03), as well as all age group survival to hospital discharge (aOR = 1.54; 95% CI, 1.01–2.36; P = .046). There was a trend with CV-CPR toward neurologically favorable survival in all age groups (aOR = 1.35; 95% CI, 0.86–2.10; P = .19) and all age group survival to hospital admission (aOR = 1.29; 95% CI, 0.91–1.84; P = .157).

Conclusion:

In cases of cardiac arrest following drowning, bystander CV-CPR was statistically significantly associated with neurologically favorable survival in children aged five to 15 years and survival to hospital discharge.
