Blunt SBI is infrequent and its diagnosis may be difficult, especially in the face of confounding variables. The purpose of this study was to evaluate methods for making the diagnosis of blunt SBI. ⋯ Alone or in combination, current diagnostic approaches lack sensitivity in the diagnosis of perforated SBI. Improvements in diagnostic methods and approaches are needed to ensure the prompt diagnosis of this uncommon but potentially devastating injury.

Clinical Trial
Influence of low tidal volumes on gas exchange in acute respiratory distress syndrome and the role of recruitment maneuvers.
BACKGROUND Use of a low tidal volume (V(T)) strategy in the treatment of acute respiratory distress syndrome can lead to a decrease in oxygenation. This study evaluated the safety and efficacy of a recruitment maneuver (RM) in this setting. ⋯ An RM transiently improves gas exchange during low V(T)ventilation. RMs are well tolerated and no hemodynamic consequences were seen.

The utility of diagnostic peritoneal lavage (DPL) as a diagnostic tool specifically for shotgun wound to the abdomen (SGWA) is unknown. This prospective study was undertaken to determine the sensitivity, specificity, and accuracy of DPL for the detection of intra-abdominal injuries following SGWA. ⋯ For patients presenting with SGWA who do not present with indications for immediate laparotomy, DPL is a reliable indicator of intra-abdominal injury and need for operative intervention.

The purpose of this study was to identify and analyze factors contributing to both airbag deployment and resulting head injuries (HIs) and to quantify the effect of airbag deployment on head injuries, in terms of odds of head injury and severity, in severe motor vehicle collisions (MVCs). ⋯ Airbag deployment did not significantly lower a driver's odds of head injury in a severe MVC, but it did significantly lower the severity of head injury. This is a significant finding, given that 72% of our study population sustained a head injury and the importance of lowering the severity of these head injuries in terms of patients' ultimate outcome. The most important factor associated with head injuries was ejection, which nearly doubled a driver's odds of head injury (odds ratio, 1.759; 95% confidence interval, 1.201-2.577). This reinforces the supplementary protective effect of an airbag and that "buckling up" and keeping occupants in the vehicle is of primary importance in the prevention of head injuries.

Blunt hollow viscus injury (HVI) is uncommon. No sufficiently large series has studied the prevalence of these injuries in blunt trauma patients. This study defines the prevalence of blunt HVI, in addition to the associated morbidity and mortality rates for this diagnosis on the basis of a series of over 275,000 trauma admissions. ⋯ HVI is a rare but deadly phenomenon. The high mortality rates reflect the severity of the HVI and associated injuries. HVI patients should be carefully monitored for related injuries and complications.
