Abstract

PURPOSE: Debate remains about the threshold cardiopulmonary resuscitation (CPR) duration associated with futile emergency department thoracotomy (EDT). To validate the CPR duration associated with favorable outcomes, we investigated the relationship between CPR duration and return of spontaneous circulation (ROSC) after EDT in blunt trauma.

METHODS: A retrospective observational study was conducted at three tertiary centers over the last 7 years. We included bluntly injured adults who were pulseless and required EDT at presentation, but excluded those with devastating head injuries. After multivariate logistic regression identified the CRP duration as an independent predictor of ROSC, receiver operating characteristic curves were used to determine the threshold CPR duration. Patient data were divided into short- and long-duration CPR groups based on this threshold, and we developed a propensity score to estimate assignment to the short-duration CPR group. The ROSC rates were compared between groups after matching.

RESULTS: Forty patients were eligible for this study and ROSC was obtained in 12. The CPR duration was independently associated with the achievement of ROSC [odds ratio 1.18; 95% confidence interval (CI) 1.01-1.37, P = 0.04], and the threshold CPR duration was 17 min. Among the 14 patients with a short CPR duration, 13 matched with the patients with a long CPR duration, and a short CPR duration was significantly associated with higher rates of ROSC (odds ratio 8.80; 95% CI 1.35-57.43, P = 0.02).

CONCLUSIONS: A CPR duration < 17 min is independently associated with higher ROSC rates in patients suffering blunt trauma.
