Multicenter Study Clinical Trial
The clinical utility of computed tomographic scanning and neurologic examination in the management of patients with minor head injuries.
The evaluation and management of patients with minor head injury (MHI: history of loss of consciousness or posttraumatic amnesia and a GCS score greater than 12) remain controversial. Recommendations vary from routine admission without computed tomographic (CT) scanning to mandatory CT scanning and admission to CT scanning without admission for selected patients. Previous reports examining this issue have included patients with associated non-CNS injuries who confound the interpretation of the data and affect outcome. ⋯ The sensitivity of the CT scan was 100%, with positive predictive value of 10%, negative predictive value of 100%, and specificity of 51%. The use of CT alone as a diagnostic modality would have saved 3924 hospital days, including 814 ICU days, and $1,509,012 in hospital charges. Based on these data, we believe that CT scanning is essential in the management of patients with MHI and that if the neurologic examination is normal and the scan is negative patients can be safely discharged from the emergency room.

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.

The management of acute cervical spine injuries has traditionally used bed-based skeletal traction until all non-neurologic injuries have been evaluated. This treatment method substantially hinders the ability to transport patients and to perform imaging studies and surgical procedures. In contrast, early application of a halo/vest apparatus provides immediate cervical stabilization and facilitates the diagnostic work-up and treatment of the patients with multiple injuries. ⋯ There were 35 neurosurgical procedures on 32 patients and 41 non-neurosurgical surgical procedures on 24 patients. Over the past year, 20 of 21 patients (95%) had their halo/vest placed in the emergency department. The data demonstrate that many diagnostic and surgical procedures need to be performed on patients with unstable cervical spine injuries.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Clinical Trial
Prospective evaluation of preoperative fluid resuscitation in hypotensive patients with penetrating truncal injury: a preliminary report.
Although intravenous (IV) fluid therapy is routinely prescribed for hypotensive injury victims, there are concerns that elevating the blood pressure before hemorrhage is controlled may be detrimental. This is a preliminary report of an ongoing randomized study designed to evaluate the effect fluid resuscitation, delayed until surgical intervention, has on the outcome for hypotensive victims of penetrating truncal injury. In the first year, 300 consecutive patients with gunshot or stab wounds to the trunk who had a systolic blood pressure of 90 mm Hg or less were entered into the study. ⋯ There were no significant differences in the rate of survival to hospital discharge (immediate resuscitation group, 56%; delayed resuscitation group, 69%). There were no significant differences in the rate of postoperative complications. Further study is necessary to determine if it is advantageous to delay fluid resuscitation until surgical intervention.

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.
