This article presents a series of patients with traumatic retrobulbar hematoma and orbital trauma, treated with extended pterional orbital decompression. ⋯ The presented pterional orbital decompression represents an effective alternative approach for patients with sight-threatening retrobulbar hematoma or orbital trauma, especially in cases that require direct access to damaged structures and maximal decompression of the orbit. Immediate detection and treatment of orbital hematomas is mandatory for acceptable outcome of eye function.

The purpose of this study was to describe differences in demographics, injury pattern, transfusion needs, and outcome of pelvic fractures in older versus younger patients. ⋯ In older patients, pelvic fractures are more likely to produce hemorrhage and require angiography. Fracture patterns differ in older patients, with LC fractures occurring more frequently, and commonly causing significant blood loss. The outcome of older patients with pelvic fractures is significantly worse than younger patients, particularly with higher injury severity. Recognition of these differences should help clinicians to identify patients at high risk for bleeding and death early, and to refine diagnostic and resuscitation strategies.

The purpose of this study was to determine patterns of spinal injury and clinical outcomes resulting from motorcycle crashes. ⋯ The thoracic spine is the most commonly injured spinal region in motorcycle crashes. Multiple level injuries are common. Protocols concentrating on the radiographic clearance of the cervical region may miss a significant number of spinal injuries. Vigilance is required in assessing these patients, who often have multiple injuries.

The purpose of this study was to investigate the effects of temperature on oxidative stress in brain stem tissue induced by hemorrhagic shock. We researched the hemorrhagic oxidative stress at various core temperatures using reduced glutathione (GSH) levels and thiobarbituric acid-reactive substances (TBARS) as markers of lipid peroxidation in brain stem homogenate. ⋯ Moderate systemic hypothermia (28 degrees C) appears to protect brain stem tissue from oxidative stress during severe hemorrhagic shock in rats, as indicated by insignificant change in tissue TBARS and GSH concentrations. These results suggest antioxidant protective effects of moderate systemic hypothermia in metabolically active brain stem tissue during hemorrhagic shock. Similar effects in humans remain to be studied.
