The purpose of this study was to evaluate the ability of abdominal ultrasound (US) to detect intra-abdominal injuries that required surgical repair. We therefore retrospectively reviewed 353 patients with nontrivial blunt abdominal trauma. ⋯ Accuracy was 99.4%, the positive predictive value was 100%, and the negative predictive value was 99.4% (prior probability of disease was 7.65%). We believe that abdominal US should be considered an important tool and an integral part in the work-up of major trauma victims.

Fifty-eight lower limb salvage attempts over a 10-year period were retrospectively scored using the Mangled Extremity Syndrome Index (MESI), Mangled Extremity Severity Score (MESS), Predictive Salvage Index (PSI), and the Limb Salvage Index (LSI). Primary amputations were excluded. ⋯ Although most failed limb salvage attempts could be identified early in the course of management, a significant percentage of our patients suffered prolonged reconstructive efforts. We conclude that efforts must be directed at more precisely determining the factors that aid in the decisions to terminate futile salvage efforts.

Comparative Study
Immediate positive pressure ventilation with positive end-expiratory pressure (PEEP) improves survival in ovine smoke inhalation injury.
The purpose of this study was to compare the effects of immediate initiation of positive pressure ventilation (PPV) with positive end-expiratory pressure (PEEP) versus the initiation of PPV with PEEP only after hypoxemia ensued following severe smoke inhalation injury. ⋯ Immediate PPV + PEEP did not prevent the development of hypoxia and was associated with increased pleural fluid formation. Death within 96 hours in the delayed group was the result of respiratory failure aggravated by bronchial cast formation despite vigorous pulmonary toilet. Early positive pressure ventilation with PEEP, preferably initiated immediately after the inhalation insult, significantly increases short-term survival and is associated with decreased tracheobronchial cast formation in this ovine model of severe smoke inhalation injury.

Case Reports
Spontaneous endobronchial erosion and expectoration of a retained intrathoracic bullet: case report.
In all four previously reported cases of endobronchial erosion from retained intrathoracic foreign objects, the object eventually required surgical removal. We report the case of a patient with a bullet in the left hemithorax who developed bronchial erosion and hemoptysis 3 months after the injury, with subsequent expectoration of the bullet. Although most foreign bodies within the thorax pose no special problems, migration of the object or the development of symptoms warrants investigation and possibly subsequent surgical removal of the object.

Comparative Study
The effects of hypothermia and injury severity on blood loss during trauma laparotomy.
To assess the relationships between core temperature (T) and other factors relating to operating room (OR) blood loss and mortality following abdominal injury, the records of 122 patients undergoing laparotomy for trauma at Detroit Receiving Hospital over a 1-year period (1989) were reviewed. Most injuries were penetrating (86%) and the mortality rate was 8.2%. Overall, 57 of 122 (47%) had hypothermia (T < or = 35 degrees C) upon arrival in the OR. ⋯ Trauma scores and the presence of shock preoperatively correlate with the development of intraoperative hypothermia. Hypothermic patients with similar injury severity have greater blood loss. Prevention and rapid correction of hypothermia during resuscitation and surgery appear to be extremely important in reducing blood loss in this patient population.
