A triage system was established as the initiating mechanism for a trauma team response to assist the assessment and early management of patients presenting to an accident and emergency department. A checklist of triage criteria was used. During a 6-month period, 342 patients (29.7% of trauma admissions) satisfied the triage criteria, which should have resulted in an average of 1.9 trauma team calls per day. ⋯ Using data from 564 patients from both series, logistic regression analysis of the power of the triage criteria to predict serious injury contributed to a revision of the triage criteria. This trauma triage tool and trauma team response constitute a valid approach to the early hospital management of trauma patients. This system may be more appropriate or achievable in many hospitals than the construction of dedicated trauma reception units or permanent surgical staffing of general Accident and Emergency departments.

From January 1, 1985, to September 10, 1988, 210 consecutive patients with high-energy pelvic ring disruptions (exclusive of acetabular fractures) were admitted to a statewide referral center for adult multiple trauma. They were treated by one of four attending orthopaedic traumatologists per protocol as determined by their injury classification and hemodynamic status; the injury classification system was based on the vector of force involved and the quantification of disruption from that force, i.e., lateral compression, anteroposterior compression, vertical shear, and combined mechanical injury. Of the 210 patients, 162 had complete charts: 126 (78.0%) were admitted directly from the scene, 110 (67.9%) were injured in motor vehicle or motorcycle accidents, 25 (15.0%) were admitted in shock (blood pressure less than 90 mm Hg), the average Glasgow Coma Score was 13.2, and the average Injury Severity Score was 25.8. ⋯ Overall mortality was 8.6% (lateral compression, 7.0%; anteroposterior, 20.0%, vertical shear, 0%; combined mechanical, 18.0%). The cause of death was associated with the pelvic fracture in less than 50%; no patient with an isolated or vertical shear pelvic injury died. We conclude that the predictive value of our classification system (incorporating appreciation of the causative forces and resulting injury patterns) and our classification-based treatment protocols reduce the morbidity and mortality related to pelvic ring disruption.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of a hydrocolloid dressing and silver sulfadiazine cream in the outpatient management of second-degree burns.
The purpose of this prospective randomized study was to evaluate the use of an occlusive hydrocolloid dressing (Duoderm hydroactive, Squibb) and silver sulfadiazine (Silvadene, Marion) cream in the outpatient management of second-degree burns. The inclusion criteria consisted of burns less than 15% total body surface area that were evaluated within 24 hours of injury and did not require hospital admission. Fifty patients were randomly assigned after having been screened through a list of seven exclusion criteria. ⋯ Duoderm-treated burns had statistically significantly better wound healing, repigmentation, less pain, fewer dressing changes, less time for dressing changes, and less cost. Duoderm-treated patients had statistically significantly less limitation of activity, better patient compliance, greater patient comfort, better overall acceptance, and felt the treatment was more aesthetically pleasing. The results reveal that the Duoderm Hydroactive dressings are superior to Silvadene cream in the outpatient management of second-degree burns.

Comparative Study
A stepwise logistic regression analysis of factors affecting morbidity and mortality after thoracic trauma: effect of epidural analgesia.
Rib fractures and other chest wall injuries can lead to weak ventilation, atelectasis, and even death. Whereas such injuries in young patients are usually well tolerated, relatively minor chest wall trauma can be serious in elderly patients. Epidural analgesia, by improving pain control and ventilatory function, might improve morbidity and mortality rates compared to other forms of analgesia. ⋯ In spite of more severe thoracic trauma in epidural patients as measured by the Abbreviated Injury Score for the chest (epidural = 3.3 +/- 0.1, IV/IM = 2.8 +/- 0.1; p less than 0.05) the use of epidural analgesia was an independent predictor of both decreased mortality (p = 0.0035) and a decreased incidence of pulmonary complications (p = 0.0088). Epidural analgesia has a positive effect on outcome in elderly trauma victims with chest wall injury and is useful in high-risk patients. Increased costs associated with epidural analgesia are minimal and are justified by improvements in outcome.

Aortic crossclamping (AOXC) is performed frequently in hypotensive trauma patients who may have had a head injury. The effect of AOXC on the injured brain is unknown. We studied the effect of AOXC on mean arterial pressure (MAP), intracranial pressure (ICP), cerebral blood flow (CBF), cerebral perfusion pressure (CPP), and cerebral water content in a porcine model of focal cryogenic brain injury. ⋯ Cerebral water content at the site of the focal brain injury was greater than in nonlesioned cortex but there was no significant difference between groups despite a greater positive fluid balance in hemorrhaged animals. AOXC improved perfusion to the injured brain without a significant increase in ICP. Increased MAP induced by AOXC and large fluid resuscitation appeared to have no detrimental effect on ICP, CBF, cerebral water content, or CPP in this model of brain injury.
