Emergency thoracotomies in the largest trauma center in Denmark: 10years' experience.

Abstract

The aim of our study was to investigate the outcome in terms of 30-day survival and to determine whether preoperative factors could predict the outcome. All patients who underwent an emergency thoracotomy (ET) during the period 2000 to 2009 were included. The patients were divided into two groups: emergency department thoracotomy and operating room thoracotomy. Data on demographics, mechanism of injury, intraoperative data, Injury Severity Scores (ISS), probability of survival, signs of life, transportation time, indications, and outcome were collected. Forty-four ETs were performed. The mechanisms of injury were penetrating in 28 (64%) and blunt in 16 (36%) cases. In the emergency department thoracotomy group, the survival was 45 versus 20% for penetrating and blunt trauma, respectively. The total survival was 33%. In the operating room thoracotomy group, the survival was 83%. The survivors had a significantly lower ISS and a higher calculated probability of survival. The calculated mean probability of survival was 44 and 84% in the emergency department thoracotomy and operating room thoracotomy groups, respectively. The actual survival was similar, with 33% in the emergency department thoracotomy group and 83% in the operating room thoracotomy group. The probability of survival and ISS are good predictors of survival in these patients and should be included in the future in order to make upcoming studies easier to compare. Patients with very high ISS or low probability of survival survived, justifying the procedure in our center.
