The need for simultaneous diagnosis and treatment of life-threatening intracranial mass lesions and intra-abdominal injury results in controversy over the appropriate triage of unconscious blunt trauma patients with stable vital signs. To aid in early decisions for these patients, a retrospective analysis of 290 patients with Glasgow Coma Scale (GCS) scores < or = 8 and systolic blood pressures (SBP) > 90 mm Hg was undertaken. The hypothesis of this study was that life-threatening abdominal injury frequently occurs in these patients and injuries cannot be consistently identified from vital signs alone. ⋯ Patients with concurrent injuries were more likely to come from motor vehicle crashes than falls (p < 0.001). Although severe abdominal injuries (A-AIS > or = 3) were frequently identified based on SBP and HR, the use of clinical signs alone resulted in more missed injuries than did using the results diagnostic peritoneal lavage (DPL). This study suggests that all unconscious normotensive blunt trauma patients undergo immediate DPL to prevent missing life-threatening injuries.

Penetrating thoracoabdominal trauma presents a difficult diagnostic dilemma. Violation of the diaphragm may be very difficult to establish. Conventional diagnostic procedures such as chest radiography, computed tomography, and diagnostic peritoneal lavage have been shown to be unreliable. ⋯ There were no procedure-related complications. Thoracoscopy is a safe, accurate, reliable diagnostic technique for evaluating thoracoabdominal penetrating trauma. It is less invasive than celiotomy and has the added benefit of diagnosis and therapy of the intrathoracic injuries.

Quality assurance/quality improvement (QA-QI) is a priority for maintaining the highest standards of care in trauma systems. To be an effective tool for system review, the QA-QI indicators should identify patients with higher rates of morbidity and mortality from injury. While the American College of Surgeons (ACS) and the Joint Commission on Accreditation of Health Care Operations have identified certain audit filters within the trauma system, there are few data to substantiate the value of these audit filters for trauma care. ⋯ This study demonstrates that several ACS clinical indicators, as currently written, are not useful in identifying patients at higher risk for poor outcome. The indicators need further definition to be of value in the quality review process. Specifically, the study suggests that audit filters should be data driven and based upon analyses of large populations of injured patients and their outcomes to be valid QA-QI tools.

The relative impact of inhalation injury, burn size, and age on overall outcome following burn injury was examined in 1447 consecutive burn patients over a five and a half year period. The overall mortality for all patients was 9.5% (138 of 1447). The presence of inhalation injury, increasing burn size, and advancing age were all associated with an increased mortality (p < 0.01). ⋯ Using multivariate analysis inhalation injury was found to be an important variable in determining outcome, but the most important factor in predicting mortality was %TBSA burn (accuracy = 92.8%) or a combination of %TBSA burn and patient age (accuracy = 93.0%). Adding inhalation injury only slightly improved the ability to predict mortality (accuracy = 93.3%). The presence of inhalation injury is significantly associated with mortality after thermal injury but adds little to the prediction of mortality using %TBSA and age alone.

Comparative Study
A prospective comparison of two multiple organ dysfunction/failure scoring systems for prediction of mortality in critical surgical illness.
Multiple organ failure (MOF) is the primary cause of death in surgical intensive care units (SICU). Mortality increases with an increasing number of failed organs, but it has been recognized that lesser degrees of organ dysfunction occur commonly. Such gradations of the multiple organ dysfunction syndrome (MODS) are postulated to provide more descriptive and predictive power. ⋯ Death was equally likely for comparable degrees of organ dysfunction and failure. Mortality increased (p < 0.01, ANOVA) with higher scores in both systems. In patients with 9-12 organ dysfunction points, the number of failed organs was 1.5 +/- 0.2 in 34 survivors, versus 2.9 +/- 0.3 in the 14 nonsurvivors (p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
