Wound management in open pelvic fractures has used fecal diversion, debridement, and closure by secondary intention to prevent pelvic sepsis. Colostomy care and takedown adds to the morbidity and resource utilization of this approach. We reviewed our experience to determine if a selective approach to fecal diversion based on wound location was possible. ⋯ No patients with anterior wounds and an intact fecal stream developed pelvic sepsis. Colostomy may not be necessary in all patients with open pelvic fracture. Protocols using fecal diversion based on wound location appear to be safe and may decrease resource utilization and subsequent morbidity related to colostomy closure.

Some patients who survived severe hemorrhagic shock (HS) seem to exhibit persistent subtle neurobehavioral deficits. This finding is of concern if limited hypotensive fluid resuscitation is applied in hypotensive victims with penetrating trauma. This study was designed to determine whether subtle brain damage would occur in rats after severe prolonged HS. We hypothesized that rats surviving HS with mean arterial pressure (MAP) controlled at 40 mm Hg for 60 minutes would recover with slight permanent brain damage in terms of cognitive function without morphologic loss of neurons and that rats surviving HS with MAP at 30 mm Hg for 45 minutes (60 minutes were not tolerated) would have grossly abnormal brain function and loss of neurons. ⋯ HS at MAP 40 mm Hg for 60 minutes or MAP 30 mm Hg for 45 minutes does not cause subtle functional or histologic brain damage in surviving rats. Controlling MAP at 30 mm Hg carries a risk of sudden cardiac arrest. These data suggest that limited fluid resuscitation, to maintain MAP at about 40 mm Hg, as recommended for victims of penetrating trauma with uncontrolled HS, is safe for the brain.

Although several retrospective studies have been published concerning nonoperative management of minor liver and spleen injuries, few studies have prospectively analyzed the results of nonoperative management for higher-grade liver and spleen injuries. Is it possible to manage extensive hepatic or splenic injuries with hemoperitoneum nonoperatively? The current study was conducted to evaluate the safety of nonoperative management of blunt hepatic and splenic trauma with significant hemoperitoneum in hemodynamically stable patients regardless of injury severity. ⋯ We suggest that nonoperative management may be undertaken successfully in appropriately designed areas with close observation for the hemodynamic stable patient.

To evaluate the functional outcome and return to work after suture of upper extremity nerves after low-velocity missile injury. ⋯ Nerve suture between the wrist and axilla and supplemental techniques achieve functional recovery in the majority of patients after missile injury with good expectations for return to work, except in combined median and ulnar nerve injuries.

To evaluate functional recovery after suture of the sciatic nerve after missile injury. ⋯ We advocate exploration of the sciatic nerve at any level within 3 months if no spontaneous recovery occurs after a missile injury. We do not advocate exploration of the sciatic nerve at the buttock level if only peroneal function is lost except in children.
