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.

Review
The 1991 Fraser Gurd Lecture: evolution of airway control in the management of injured patients.
The evolution of methods for airway control has been an important factor in improving overall trauma care. Many important advances have been made in technique, tubes, and timing. Current methods of airway control are listed in Table 2 and are categorized as emergency or elective. ⋯ The role of differential ventilators in the management of unilateral pulmonary parenchymal injury requires clinical validation. Intravascular membrane oxygenators have been proposed in advanced pulmonary insufficiency in a ventilated patient. Thus, while many important strides have been made in airway management following trauma, there remain great challenges in addressing the persistent problem of systemic hypoxemia after multiple injuries.

Review Case Reports
Appendiceal transection in a child associated with a lap belt restraint: case report.
The seatbelt syndrome refers to the spectrum of injuries associated with lap belt restraints and includes intestinal tears, perforations, and transections; mesenteric disruptions; and lumbar distractions, dislocations, and fractures. We report a case of appendiceal transection associated with a lap belt restraint in a small child.

The effect of alcohol intoxication at the time of injury on hospital outcome was evaluated in 520 adult patients diagnosed with brain injury who were admitted to the emergency department of Harborview Medical Center. Data were collected for each subject's status from field intervention through hospitalization. ⋯ Compared with subjects who were not intoxicated, intoxicated patients were more likely to be intubated in the field or emergency department (relative risk [RR] = 1.3, 95% confidence interval [CI] = 1.1-1.5), require placement of an intracranial pressure bolt (RR = 1.4, 95% CI = 1.1-1.8), develop respiratory distress requiring ventilatory assistance during hospitalization (RR = 1.8, 95% CI = 1.0-3.3), or develop pneumonia (RR = 1.4, 95% CI = 0.9-2.2). The similarities in the clinical presentation of patients with acute brain injury and those who are intoxicated appear to influence prehospital care and also suggest that a more objective assessment of cerebral injury than provided by clinical diagnostic measures alone is required, thus accounting for the elevated likelihood of intracranial pressure monitoring in intoxicated trauma patients.

We retrospectively reviewed the medical records, plain films, CT scans and complex-motion tomographic studies (TOMOS) of 216 consecutive patients with cervical injuries to determine the uses and limitations of CT in the evaluation of cervical trauma and the indications, if any, for the continued use of TOMOS in evaluating cervical trauma. There were 453 fractures and 104 subluxations or dislocations of the cervical spine in the 216 patients. Plain films detected 58% (262 of 453) of the fractures and 93% (97 of 104) of the subluxations and dislocations; and 94% (202 of 216) of the patients with abnormalities were identified. ⋯ In the 20 patients who underwent both CT scanning and TOMOS, TOMOS detected more fractures, subluxations, and dislocations than CT scanning. Complex-motion tomographic studies detected atlanto-occipital dislocation and subluxation of the vertebral bodies and fractures of the spinous processes, lateral masses, articular processes, vertebral bodies, and dens better than CT scanning. Although the more routine use of CT scanning in evaluating cervical trauma should increase the detection of cervical abnormalities to near 100%, TOMOS remain the gold standard of diagnosis for atlanto-occipital dislocation, subluxation of the vertebral bodies, and fractures of the lateral masses, articular processes, vertebral bodies, and dens.
