To assess the need for a trauma system in San Diego County, a concurrent audit of trauma care was performed by an independent consultant in 1982. During the study period from 15 March through 15 June 1982, 591 consecutive major trauma victims (MTV) were collected by the 30 participating hospitals. All medical records, including autopsy reports, were audited for the timeliness and appropriateness of diagnosis and definitive care. ⋯ The care of MTV was considered suboptimal in 32% of patients before regionalization, compared to 4.2% after regionalization (p less than 0.01). Preventable deaths occurred in 13.6% of fatalities occurring before implementation of a trauma system, compared to 2.7% after implementation (p less than 0.01). Regionalization of trauma care significantly reduced delays, inadequate care, and preventable deaths due to trauma.

Performance of surgery for trauma is an important part of residency training, yet what constitutes an adequate exposure to trauma surgery is ill defined. A retrospective review of records at a metropolitan receiving hospital was carried out for the academic year 1981-1982. Of the 50,902 patients treated in the Emergency Room more than one third were seen by a surgical resident. ⋯ An adequate education in trauma must be based on a large experience in the nonoperative resuscitation, diagnosis, and treatment of trauma victims. Nevertheless, the number of cases performed as operating surgeon provides a useful means of evaluation experience in trauma. Thirty cases are suggested as an appropriate level of exposure to the surgery of trauma, yet only one third of applicants to the American Board of Surgery attained this level.

The quantity of fluid retained during the first 48 hours of resuscitation has been suggested as an indicator of burn severity and mortality (13). In this study of 82 adult burned patients with more than 20% total body surface burns we found that the net fluid retention during the first 48 hours of resuscitation was a predictor of burn mortality and additionally 230 cc of retained fluid per kilogram of lean body mass in the initial 48 hours postburn was an excellent means for separating survivors from nonsurvivors. Fluid retention as an indicator of burn severity and mortality was compared to other methods of predicting burned patient mortality. ⋯ A comparison was made between fluid retention data, per cent body surface area burned, and the calculated Abbreviated Burn Severity Index and patient mortality. The power of each variable to predict mortality was evaluated by stepwise regression analysis. From this analysis net fluid retention during the first 48 hours of resuscitation was as accurate as the Abbreviated Burn Severity Index and was a better predictor of mortality than individual components of that Index.

Previous studies have emphasized injury mechanism, wound site, and presenting vital signs as critical determinants for survival following penetrating cardiac injury. Our experience suggests pericardial tamponade is another crucial factor and is the basis for this study. Prognostic features were reviewed in 100 consecutive, unselected patients with acute cardiac injuries. ⋯ Patients with tamponade had a survival of 73% (24/33) compared to 11% (5/44) in those without its protective effect. The presence of tamponade improved survival (p less than 0.05) following stab injuries (77% vs. 29%), gunshot wounds (57% vs. none), right heart wounds (79% vs. 28%), left heart injuries (71% vs. 12%), and overall in patients arriving with vital signs (96% vs. 50%). Multivariant discriminant analysis by logistic regression demonstrated cardiac tamponade was a critical independent factor in patient survival, and suggested that it may be more influential than presenting vital signs in determining outcome.

Burn injury cases were identified from a population-based sample of trauma visits to hospital emergency departments in northeastern Ohio during 1977. The 199 cases represented 2.4% of all trauma incidence visits by residents of the five-county study region. Ninety-five per cent of the burn cases were released from the emergency department directly after treatment. ⋯ Most burns occurred at home or the workplace. The youngest employed age group sustained the highest rate of work-related burns. Hot or corrosive substances caused two thirds of all burns; fire and flames caused one fourth.
