Prehospital or admission hypotension doubles the mortality for patients with severe head injury (SHI = Glasgow Coma Scale score less than or equal to 8). To our knowledge no study to date has determined the effects of intraoperative hypotension [IH: systolic blood pressure (SBP) less than 90 mm Hg] on outcome in patients with SHI. This study examined 53 patients who had SHI and required early surgical intervention (surgery within 72 hours of injury). ⋯ The duration of IH was inversely correlated with Glasgow Outcome Scale using linear regression (R = -0.30; p = 0.02). Despite vigorous fluid resuscitation in the IH group, additional pharmacologic support was used in only 32%. These data suggest that IH is not uncommon after SHI (32%) and that it does have a significant effect on patient outcome.

To evaluate the usefulness of routine pelvic x-ray films in the resuscitation of blunt trauma victims, 1395 patients were prospectively evaluated over a 13-month period. Of these, 810 (58%) were awake with Glasgow Coma Scale scores greater than or equal to 13 and were enrolled into the study. A history, with directed questions regarding pelvic pain, a clinical examination of the pelvis, and an anterior-posterior pelvic x-ray film (APPX) were obtained for each patient. ⋯ These were minor fractures that did not affect the clinical course. Total charges incurred to diagnose pelvic fractures in this low-yield patient group were $88,028. We conclude that the practice of obtaining a screening APPX is not necessary or cost-effective in the management of awake blunt trauma patients who do not complain of pain and who have normal pelvic physical examination results.

Overtriage (i.e.; transport of patients with minimal injuries to a trauma center) has been accepted as necessary to avoid missing clinically significant injuries. We reviewed our experience with 344 patients (ISS less than or equal to 4) who were admitted to a level I trauma center during a 2-year period. The trauma team was activated for 209 patients (TA), and emergency department referrals accounted for 135 (ED). ⋯ Compliance with FTC yields an inherent overtriage of minimally injured patients; however, noncompliance with FTC compounds the overtriage rate. Failure to comply with FTC is costly, labor intensive, and may represent misuse of the trauma system. We propose continual re-education of prehospital personnel, increased responsibility of all hospitals in the trauma center catchment area, and protocols for "downstaging" trauma resuscitation in minimally injured patients.

Severe head injury is the leading cause of traumatic death. When a severe head injury is combined with hypotension the mortality doubles. The use of asanguineous salt solutions to maintain blood pressure, however, may contribute to cerebral swelling and intracranial hypertension. ⋯ We found a significant correlation between total Na and FLD balance (R2 = 0.54; p less than 0.05). However, we found no significant correlation between total FLD and maximum ICP (R2 = 0.081), ICP score (R2 = 0.01), or outcome (R2 = 0.066), no significant correlation between FLD balance and maximum ICP (R2 = 0.000), ICP score (R2 = 0.000), or outcome (R2 = 0.01), and no significant correlation between total Na and maximum ICP (R2 = 0.000), ICP score (R2 = 0.001), or outcome (R2 = 0.02). We conclude that Na and FLD administration are not independent determinants of ICP during the initial 72 hours after brain injury.

Recent animal studies have shown that aggressive saline infusion may produce significant mortality in models of moderately severe (20-30 mL/kg) uncontrolled hemorrhage. The postulated mechanism is an increase in hemorrhage that accompanies restoration of normal blood pressure. Although aggressive saline infusion and restoration of blood pressure appear indicated when hemorrhage is potentially lethal (40-45 mL/kg), we hypothesized that the attempt to restore blood pressure with aggressive saline infusion would not improve survival. ⋯ One-hour survival was 87.5%, 37.5%, and 12.5% for groups I, II, and III, respectively. Intraperitoneal hemorrhage for the three groups was 8.2 mL/kg, 39.9 mL/kg, and 6.7 mL/kg. The amount of saline infused was 55.8 mL/kg in group I and 90 mL/kg in group II.(ABSTRACT TRUNCATED AT 250 WORDS)
