Survival outcomes of emergency thoracotomy in severely injured patients performed by a general surgeon at a rural university hospital in Thailand

Abstract

Background: Emergency thoracotomy is a potentially life-saving maneuver for trauma patients in extremis. Since trauma scenarios, in rural locations, usually occur with a high incidence of a severe injury that leads to hemorrhagic shock or cardiopulmonary arrest. The objective of this study was to analyze the experience in emergency thoracotomy performed by a general surgeon in a rural area in Thailand. Methods: This retrospective study was conducted by analyzing the patient records including demographics, mechanisms of injuries, specific organ injury, surgical approach, life-saving surgical procedure, and postoperative outcome for all patients who underwent emergency thoracotomy in the Department of Surgery, Srinakharinwirot University hospital between January 2010 and December 2020. Results: Twelve patients underwent emergency thoracotomy within 1 hour after arrival and were equally divided between blunt and penetrating injuries with 6 (50%). A mean patient age of 34.8 ± 15.2 years (range 16–55), mean systolic blood pressure on arrival was 65.8 ± 35.2 mmHg (range 0–100 mmHg), and the mean injury severity score (ISS) was 54.6 ± 25.2 (range 26–75). Profound hemorrhagic shock is a major indication for emergency thoracotomy. The overall survival rate was 41.7% (5/12 patients) without survivors from cardiac injuries. Four patients (66.7%) in the penetrating and 1 patient (16.7%) in the blunt intrathoracic injury group were survived and discharged from the hospital. Conclusion: Emergency thoracotomy offers a chance for survival at 41.7% for trauma patients who present with extremes in this study. Rapid decision-making, good operative technique, and adequate patient selection are crucial for reasonable outcomes.
