AbstractIn hypotensive blunt trauma patients with a diminished level of consciousness, it may be difficult to decide whether to proceed with immediate head CT scanning or urgent laparotomy or thoracotomy. The purpose of this study was to determine the frequency of emergency craniotomy and urgent laparotomy or thoracotomy in a group of 734 blunt trauma patients with initial hypotension (BP < 90 mm Hg systolic) admitted to the eight level I and II trauma centers in North Carolina. The mean initial systolic blood pressure was 64 +/- 26 mm Hg, and the mean Trauma Score was 8 +/- 5.8. Serious head injury (AIS head > or = 3) was present in 40% (293 of 734). Of 734 patients studied, 9.4% (69 of 734) died in the emergency department. Head CT scanning was performed on 47% (344 of 734) and produced positive results for 26% (202 of 734). Emergency craniotomy for intracranial hemorrhage was performed on 2.5% (18 of 734) (ten subdurals, three epidurals, and five other intracranial hemorrhages). Twenty-one percent (154 of 734) underwent urgent laparotomy, thoracotomy, or both. Overall hospital mortality for hypotensive blunt trauma patients was 36% (263 of 734). Although serious head injury occurs commonly (40%) in hypotensive blunt trauma patients, frequency of urgent laparotomy (21%) is 8.5 times greater than emergency craniotomy for intracranial hemorrhage (2.5%). This information may be used by trauma teams in prioritizing care for hypotensive blunt trauma patients.
