The primary goal of triage is to identify the majority of field trauma victims at risk for life-threatening injuries. When triage criteria are made sufficiently sensitive to accomplish this goal, high rates of overtriage occur. Orange County's original physiologic criteria were associated with an overtriage rate of 18-40% depending on the definition of a major trauma victim. ⋯ Despite this apparent high rate of overtriage, only 5.5% of all paramedic transports were for patients judged to have met field triage criteria. Based on this experience, an approach is suggested for evaluating the balance between over- and undertriage that occurs for a given set of triage criteria. Once this balance has been defined, triage guidelines can be modified to meet regional triage objectives.

Physical examination is often unreliable in the evaluation of blunt abdominal trauma. The utility of computed tomography (CT) in the early management of abdominal trauma in the absence of definite signs is controversial. CT was prospectively evaluated as an adjunct to physical examination in the initial assessment of blunt abdominal trauma. ⋯ Patients with acute pancreatic injuries may have normal CT findings. Eighty-six per cent of laparotomies were therapeutic. In conjunction with close clinical monitoring, CT was reliable in evaluation of blunt abdominal trauma in a selected group of patients.

Comparative Study
A prospective study of 91 patients undergoing both computed tomography and peritoneal lavage following blunt abdominal trauma.
Recent reports comparing computed tomography of the abdomen (CTA) and diagnostic peritoneal lavage (DPL) following trauma have been contradictory. A 10-month prospective study was conducted at our trauma center comparing both methods. Criteria for entry into the study included suspected blunt abdominal trauma without indication for immediate laparotomy, with either equivocal abdominal examination, diminished sensorium, or neurologic deficit. ⋯ The results of CTA and DPL were compared to the findings at laparotomy or the clinical course of those not explored. The sensitivity, specificity, and accuracy for initial CTA were 60%, 100%, and 91%; for review CTA 85%, 100%, and 97%; for DPL 90%, 100%, and 98%. We conclude that: even with experienced examiners, CTA offers no diagnostic advantage over DPL in blunt trauma; because of relative costs, we do not recommend the routine application of CTA; CTA is a reliable alternative when circumstances prevent the performance of DPL.

Twenty-one children admitted between December 1981 and May 1985, with greater than 80% total body surface area burn (TBSAB), underwent total excision and grafting of all of their wounds within 72 hours of injury. Twelve survivors (with an average TBSAB of 89%, 82% third degree) were studied in detail describing the length of hospital stay (77 +/- 10 days), number of operative procedures (7.8 +/- 0.8), total blood loss (12 +/- 2 blood volumes), the number of patients who experienced septic episodes (three), the number of patients who required amputation (four), range of motion, degree of scarring, ability to perform daily activities, and psychological adjustment. ⋯ One third of the children had excessive fear, regression, and neurotic and somatic complaints, but all of them showed remarkable energy in adapting to their disabilities. We conclude that the final outcome, for these patients, can only be assessed as they achieve late adolescence and young adulthood.
