Gunshot Injuries to the Extremity: Is Immediate General Surgery Presence Needed?

Abstract

Gunshot wounds (GSW) are becoming increasingly prevalent in urban settings. GSW to the trunk mandate full trauma activation and immediate surgeon response because of the high likelihood of operative intervention. Extremity GSW proximal to the knee/elbow also require full trauma activation based on American College of Surgeons Committee on trauma standards. However, whether isolated extremity GSW require frequent operative intervention is unclear. We evaluated GSW at our Level I trauma center from January 2012 to December 2016. Demographic data and injury patterns were abstracted from the trauma registry and charts. The number of GSW increased yearly but the age, gender, Injury Severity Score and injury pattern did not change (P = ns, not shown). There were 504 GSW that included an extremity and 194 (38%) involved multiple body regions. There were 310 GSW (62%) isolated to an extremity and 176 were proximal to the elbow/knee. If proximal GSW had an Emergency Department systolic blood pressure <90 mm Hg, 53 per cent underwent vascular repair, 12 per cent had soft tissue repair, and 29 per cent required no operation. If proximal GSW had an Emergency Department blood pressure >90 mm Hg, 57 per cent underwent orthopedic repair, 22 per cent required no surgery, and only 13 per cent required vascular repair (P < 0.01). In the absence of other criteria for full trauma activation such as shock, the need for the immediate presence of a general surgeon to perform emergency surgery for a GSW isolated to the extremity is low.
