The use of delayed computerized tomography in the evaluation of blunt abdominal trauma: a preliminary report.
This purpose of this study was to analyze the use of abdominal computed tomography (CT) imaging in patients with possible blunt abdominal trauma. A retrospective analysis of all trauma patients over a 1-year period (1993-1994) was conducted, with prospective study protocol in 52 patients using serial abdominal exam and hematocrits (Hcts) instead of abdominal CT for evaluation of blunt abdominal trauma. Urgent abdominal CT was used as the initial diagnostic test for evaluation of blunt abdominal trauma in 813 patients over this 1-year period. ⋯ These patients were followed with serial abdominal examinations and Hcts every 6 hours for 24 hours, and delayed CT, when applicable. CT was obtained in seven patients (13.5%) for evaluation of fall in Hct or abnormal abdominal examination; all were negative for abdominal injury. A protocol using serial abdominal exams, Hcts, and delayed abdominal CT imaging may be useful in select patients to decrease the high number of negative routine abdominal CTs that are obtained in the evaluation of blunt abdominal trauma.

Hypothermia does not result in more complications after colon surgery.
Our objective was to determine the incidence of complications in postoperative patients who were either normothermic or hypothermic. A recent, widely publicized paper concluded that the maintenance of normothermia could reduce the incidence of infectious complications and shorten hospitalization in patients undergoing colorectal surgery. However, some controversy arose regarding the methods of this paper. ⋯ Despite finding that one-third of our patients were hypothermic during elective colon resection, hypothermia had no effect on outcome variables. In contrast to the previous study, the incidence of infectious complications was identical in our patients. Before ascribing postoperative complications and increased resource utilization as adverse effects of hypothermia, further studies are indicated.
