Comparative Study
Reliability of the Glasgow Coma Scale when used by emergency physicians and paramedics.
We sought to determine the reliability of the Glasgow Coma Scale (GCS) when used by emergency physicians and paramedics. We performed a prospective sequential trial in a classroom setting, with subjects blinded to others' scoring. Nineteen university-affiliated emergency physicians and 41 professional paramedics from an urban EMS system voluntarily participated. ⋯ Intrarater reliability (r1,2) for emergency physicians was 0.66 (p < 0.01) and for paramedics was 0.63 (p < 0.01). The GCS shows statistically significant reliability (i.e., significant agreement) between emergency physicians and emergency medical technician-paramedics. It also has a significant level of intrarater reliability.

Although scores and other prehospital triage schema effectively identify injured patients who will benefit from trauma center care, those tools are relatively nonspecific. One consequence is overtriage--transport of less severely injured patients to trauma centers--with resulting expenditure of scarce resources on patients who do not benefit from an emergent and intensive response. We developed a tool that, during the prehospital phase, can sort inner-city trauma victims into those who will require ICU/OR services and those who will not. ⋯ Based on our initial experience with the two-tier response, the sorting criteria were revised and refined. The sensitivity of the current version of the two-tier criteria for predicting which trauma patients will require ICU/OR services during the first 24 hours of hospitalization approaches 95% (excluding misapplications of the tool) while avoiding urgent trauma team mobilization in 57% of patients triaged to our trauma center. Two-tiered trauma responses appear to be safe and may represent an important strategy for more effective distribution of increasingly scarce and costly resources.

The purpose of this study was to evaluate the ability of abdominal ultrasound (US) to detect intra-abdominal injuries that required surgical repair. We therefore retrospectively reviewed 353 patients with nontrivial blunt abdominal trauma. ⋯ Accuracy was 99.4%, the positive predictive value was 100%, and the negative predictive value was 99.4% (prior probability of disease was 7.65%). We believe that abdominal US should be considered an important tool and an integral part in the work-up of major trauma victims.

The results of 111 acute below-knee amputations in war wounded were reviewed. The majority of the patients were wounded by exploding mines. The amputation stumps were not closed primarily but secondarily after an average of 6.4 days. ⋯ After delayed primary closure 84% of the stumps healed without problems. The best results were obtained when the stump closure was performed within 1 week after the amputation. No cases of gas gangrene or tetanus were encountered.

Comparative Study
Head CT scanning versus urgent exploration in the hypotensive blunt trauma patient.
In 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. ⋯ 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.
