Injury of the brachial artery is a rare (5-13%) but serious complication after closed elbow dislocation without associated fractures. ⋯ Primary repair of vascular injury after closed elbow dislocation with vein graft and immediate reconstruction of ligamentous injuries results in good long-term functional outcome.

The purpose of this study was to identify factors that would aid in the diagnosis of small-bowel and mesentery injuries (SBMI) in blunt trauma patients. ⋯ The diagnosis of SBMI is often made in the presence of associated intra-abdominal injuries. Isolated SBMI are common, however, and special attention to the mechanism of injury, abdominal examination, presence of hematuria, and significant base deficit should raise suspicion to the possibility of SBMI. Findings on abdominal computed tomography that may suggest SBMI and should prompt further evaluation include free fluid, thickened bowel, and extraluminal air. Because delay in diagnosis does not seem to affect morbidity or mortality, dedication to observation and serial physical examinations will aid in the proper identification of elusive SBMI. Mortality, however, does appear to be related to the presence of hypotension on admission and associated injuries.

Comparative Study Clinical Trial
Esophageal Doppler ultrasound monitor versus pulmonary artery catheter in the hemodynamic management of critically ill surgical patients.
The pulmonary artery (PA) catheter has been used to determine hemodynamic indices; however, it has recently been criticized. This study was undertaken to evaluate an esophageal Doppler monitor (EDM) as a possible replacement for PA catheter in critically ill, mechanically ventilated patients. ⋯ Corrected flow time is a better indicator of preload than pulmonary capillary wedge pressures. EDM seems to be at least as useful as PA catheter in managing the hemodynamic status of critically ill surgical patients.

To present a series of 30 adult trauma patients who received extracorporeal life support (ECLS) for pulmonary failure and to retrospectively review variables related to their outcome. ⋯ ECLS has been safely used in adult trauma patients with multiple injuries and severe pulmonary failure. In our series, early implementation of ECLS was associated with improved survival. Although this may represent selection bias for less intractable forms of acute respiratory distress syndrome, it is our experience that early institution of ECLS may lead to improved oxygen delivery, diminished ventilator-induced lung injury, and improved survival.
