Serum bicarbonate may replace the arterial base deficit in the trauma intensive care unit.
Arterial base deficit (BD) is a commonly used marker of injury severity and endpoint of resuscitation but requires an arterial puncture and blood gas analysis. Serum bicarbonate (HCO3) is routinely obtained as part of the chemistry panel on most admissions. We hypothesized that serum HCO3 strongly correlates with arterial BD and provides equivalent predictive information. ⋯ Serum HCO3 measurement shows a strong linear correlation and similar predictive ability compared with the arterial BD. Serum HCO3 may be safely and accurately substituted for arterial BD measurement in critically injured patients.

Patterns of injury and functional outcome after hanging: analysis of the National Trauma Data Bank.
Hanging has become the second most common method of attempted suicide among adolescents, but there is little relevant epidemiologic or outcome data in the trauma literature. Additionally, there are no studies examining the degree of functional disability among survivors of hanging injury. ⋯ Hanging injuries are associated with a high overall mortality rate, with the admission GCS being the best independent predictor of outcome. However, the majority of survivors have little to no functional disability. The presence of severe disability at discharge is mainly attributed to intracranial and thoracic injury.

Screening for blunt cerebrovascular injuries is cost-effective.
Recent reports have argued that screening for blunt carotid injury is futile and have called for a cost analysis. Our data previously supported screening asymptomatic trauma patients for blunt cerebrovascular injury (BCVI) to prevent associated neurologic sequelae. Our hypothesis is that aggressive angiographic screening for BCVI based on a patient's injury pattern and symptoms allows for early diagnosis and treatment and is cost-effective because it prevents ischemic neurological events (INEs). ⋯ The cost of long-term rehabilitation care and human life after BCVI-associated neurologic events is substantial. Surgeons caring for the multiply injured should screen for carotid and vertebral artery injuries in high-risk patients.

Are temporary inferior vena cava filters really temporary?
Despite significant risk for venous thromboembolism, severely injured trauma patients often are not candidates for prophylaxis or treatment with anticoagulation. Long-term inferior vena cava (IVC) filters are associated with increased risk of postphlebitic syndrome. Retrievable IVC filters potentially offer a better solution, but only if the filter is removed; our hypothesis is that the most of them are not. ⋯ Surgeons must critically evaluate indications for IVC filter insertion, develop standard criteria for placement, and implement protocols to ensure timely removal of temporary IVC filters.

Blast lung injury: clinical manifestations, treatment, and outcome.
Blast lung injury (BLI) is a major cause of morbidity after terrorist bomb attacks (TBAs) and is seen with increasing frequency worldwide. Yet, many surgeons and intensivists have little experience treating BLI. Jerusalem sustained 31 TBAs since 1983, resulting in a local expertise in treating BLI. ⋯ Most patients with significant BLI injury require mechanical ventilation. Late deterioration is rare. Death because of BLI in patients who survived the explosion is unusual. Timely diagnosis and correct treatment result in excellent outcome.
