To prospectively evaluate a method for management of abdominal stab wounds that allows for immediate emergency room discharge. ⋯ Abdominal stab wound patients that are hemodynamically stable can be safely sent home from the emergency room when DPL counts are less than 1000 RBCs/mm3. Observation of hemodynamically stable patients allows for low laparotomy rates with minimal morbidity.

To determine the utility of routine serial head computed tomography (H-CT) for predicting need for invasive neurosurgical intervention in patients with blunt intracranial injuries (BICI). ⋯ In patients with an unchanged or normal neurologic exam, a routine serial H-CT did not influence subsequent invasive neurosurgical intervention.

Comparative Study
The role of dead space ventilation in predicting outcome of successful weaning from mechanical ventilation.
The exact mechanism by which tracheostomy results in clinical improvement in respiratory function and liberation from mechanical ventilation remains unknown. Physiologic dead space, which includes both normal and abnormal components of non-gas exchange tidal volume, is a clinical measure of the efficiency of ventilation. Theoretically, tracheostomy should reduce dead space ventilation and improve pulmonary mechanics, thereby facilitating weaning from mechanical ventilation. ⋯ There is minimal improvement in pulmonary mechanics after tracheostomy. The change in physiologic dead space posttracheostomy does not predict the outcome of weaning from mechanical ventilation. Tracheostomy does allow better pulmonary toilet, and easier initiation and removal of mechanical ventilation and control of the upper airway.

The nontherapeutic laparotomy rate in penetrating abdominal trauma remains high and the morbidity rate in these cases is approximately 40%. Selective management, rather than mandatory laparotomy, has become a popular approach in both stab wounds and gunshot wounds. The advent of spiral technology has stimulated a reassessment of the role of computed tomography (CT) in many aspects of trauma care. We prospectively investigated the current utility of triple-contrast CT as a diagnostic tool to facilitate initial therapeutic management decisions in penetrating torso trauma. ⋯ In penetrating torso trauma, triple-contrast abdominopelvic CT can accurately predict need for laparotomy, exclude peritoneal violation, and facilitate nonoperative management of hepatic injury. Adjunctive angiography and investigation for diaphragm injury may be prudent.

Multiple organ failure (OF/MOF) was found to be the major complication after blunt multiple trauma during the last 25 years and was correlated with a high mortality rate. Recently, several publications reported a decreased ARDS-related mortality, but there is little information about mortality rates from posttraumatic MOF. The purpose of this study was to describe the development of MOF-related death after blunt multiple trauma during the last 25 years. ⋯ Although MOF incidence remains unchanged, there is a significant fall in MOF-related mortality in patients with severe trauma, and death from single organ failure is virtually absent. Severe brain injury is now the leading cause of death in patients with severe multiple injuries admitted to the ICU.
