Double Jeopardy Injuries: Improved Clinical Outcomes With FAST Imaging and Subxiphoid Pericardial Window for Combined Cardiac and Abdominal Stab Wounds.

Abstract

This study reviews our experience with combined cardiac and abdominal stab wounds over 12years and reviews how changes in technology and clinical approaches have impacted our management of these patients. A retrospective cohort study was conducted from January 2008 to January 2020 at a major trauma centre in South Africa. All patients with concurrent SWs to the chest and the abdomen and required both a thoracotomy for cardiac injury and a laparotomy for an intra-abdominal injury at the same setting were included. Twenty-two cases were identified (100% male, mean age: 27years). Mean values of admission physiology: systolic blood pressure (SBP): 85mmHg, pH: 7.2, base excess: -10.2mmol/L and serum lactate 6.7mmol/L. Thirty-two percent (7/22) of cases underwent a Focused Assessment with Sonography in Trauma (FAST) scan (5 positive and 2 negative). All 7 cases had intraoperatively confirmed cardiac injuries. The thoracotomy first approach was used in 18 cases (82%), and the laparotomy first approach was used in the remaining 4 cases (18%). Nineteen (86%) of the 22 laparotomies were positive. A total of 6 patients (27%) experienced one or more complications. The mean length of hospital stay was 9days. The overall mortality was 18% (4/22) and all mortality occurred prior to 2013. Double jeopardy is still associated with an increased risk of mortality. The use of FAST and Subxiphoid Pericardial Windows (SPWs) have reduced clinical uncertainty, decreasing the need for concomitant thoracotomy and laparotomy to be performed.
