Abstract
AIM: Emergency resuscitative thoracotomy is a potentially lifesaving procedure for patients with cardiac pulmonary arrest and profound circulatory failure resulting from a severe injury. However, survival rate post-emergency resuscitative thoracotomy shows considerable variation, with many studies constrained by limited sample sizes and ambiguous criteria for inclusion. Herein, we assessed the outcomes of emergency resuscitative thoracotomy and identified predictors of futility using Japan Trauma Data Bank data. METHODS: Data of patients aged ≥18 years between 2004 and 2019 were analyzed. The primary outcome measure was survival at discharge. Descriptive statistics were used to compare the survivor and nonsurvivor groups. A multivariable logistic regression analysis was conducted to identify predictors of survival in patients undergoing emergency resuscitative thoracotomy while adjusting for confounding factors. RESULTS: Among patients who underwent emergency resuscitative thoracotomy, 684/5062 (13.5%) survived. Age <65 years (adjusted odds ratio, 1.351; 95% confidence interval, 1.130-1.615; p < 0.001), absence of cardiac pulmonary arrest on emergency department arrival (adjusted odds ratio, 1.694; 95% confidence interval, 1.280-2.243; p < 0.01), Injury Severity Score <16 (adjusted odds ratio, 2.195; 95% confidence interval, 1.611-2.992; p < 0.01), and penetrating injury (adjusted odds ratio, 1.834; 95% confidence interval, 1.384-2.431; p < 0.01) were identified as factors associated with survival at discharge. CONCLUSION: The survival rate for emergency resuscitative thoracotomy in Japan stands at approximately 13.5%. Factors contributing to survival include younger age, absence of cardiopulmonary arrest at emergency department arrival, lack of severe trauma, and sustaining penetrating injuries.
