The role of emergency department thoracotomy in patients with cranial gunshot wounds.

Background: Although several society guidelines exist regarding emergency department thoracotomy (EDT), there is a lack of data upon which to base guidance for multiple gunshot wound (GSW) patients whose injuries include a cranial GSW. We hypothesized that survival in these patients would be exceedingly low.
Methods: We used Pennsylvania Trauma Outcomes Study data, 2002 to 2021, and included EDTs for GSWs. We defined EDT by International Classification of Diseases codes for thoracotomy or procedures requiring one, with a location flagged as emergency department. We defined head injuries as any head Abbreviated Injury Scale (AIS) score of ≥1 and severe head injuries as head AIS score of ≥4. Head injuries were "isolated" if all other body regions have an AIS score of <2. Descriptive statistics were performed. Discharge functional status was measured in five domains.
Results: Over 20 years in Pennsylvania, 3,546 EDTs were performed; 2,771 (78.1%) were for penetrating injuries. Most penetrating EDTs (2,003 [72.3%]) had suffered GSWs. Survival among patients with isolated head wounds (n = 25) was 0%. Survival was 5.3% for the non-head injured (n = 94 of 1,787). In patients with combined head and other injuries, survival was driven by the severity of the head wound-0% (0 of 81) with a severe head injury ( p = 0.035 vs. no severe head injury) and 4.5% (5 of 110) with a nonsevere head injury. Of the five head-injured survivors, two were fully dependent for transfer mobility, and three were partially or fully dependent for locomotion. Of 211 patients with a cranial injury who expired, 2 (0.9%) went on to organ donation.
Conclusion: Although there is clearly no role for EDT in patients with isolated head GSWs, EDT may be considered in patients with combined injuries, as most of these patients have minor head injuries and survival is not different from the non-head injured. However, if a severe head injury is clinically apparent, even in the presence of other body cavity injuries, EDT should not be pursued.
