Abstract
OBJECTIVE: Emergency resuscitative thoracotomy (ERT) is a crucial intervention employed in prehospital settings to address life-threatening conditions, such as cardiac tamponade, hemorrhage, and air embolism. Despite its critical nature, the efficacy of prehospital ERT in enhancing survival rates compared with in-hospital procedures remains controversial. METHODS: This retrospective analysis was conducted using data from the Japanese Society for Aeromedical Services Registry between January 2020 and December 2022. After excluding nontraumatic cases, non-ERT cases, and records with missing data, 143 prehospital ERT cases were identified. The cohort was categorized into survivors (n = 3) and nonsurvivors (n = 140) based on patient outcomes. Comparative analyses were conducted on variables such as age, injury severity, time intervals, and transportation modalities using the Wilcoxon rank-sum test and Pearson's chi-square test, with the statistical significance set at P < .05. RESULTS: The overall survival rate after prehospital ERT was 2.1% (3 of 143). Only a few variables, such as hospital length of stay, showed statistically significant differences between the groups; most patient characteristics and prehospital time intervals did not. The patients who experienced cardiac arrest at the time of contact with the emergency medical service (EMS) contact had a survival rate of 0%, whereas those who arrived at the hospital with vital signs had the highest survival rate (11.1%). The presence of vital signs upon hospital arrival and the rapid initiation of intervention were identified as key factors influencing survival. CONCLUSION: These findings suggest that prehospital ERT provides limited survival benefits, with a 0% survival rate in cases of cardiac arrest at EMS contact. Therefore, further research is essential to refine the patient selection criteria and optimize ERT deployment to improve prehospital patient outcomes.
