Few, if any, complications have been reported with the nonoperative management of selected hepatic injuries diagnosed by computed tomographic (CT) scan in hemodynamically stable patients. This retrospective study was designed to evaluate complications associated with this form of management. Twenty-six patients (21%) of 128 patients with blunt hepatic injuries were treated nonoperatively over a 3-year period. ⋯ There were no deaths in our study population with nonoperative therapy. The complications of hepatic injuries initially managed by expectant observation were treated operatively or by percutaneous CT-guided drainage. Repeated CT evaluation to follow the progress of liver fracture and the occasional use of hepatobiliary scans for the identification of biliary leaks have proven useful in our experience.

Comparative Study
Continuous arteriovenous rewarming: rapid reversal of hypothermia in critically ill patients.
Hypothermia in critically ill patients can be difficult to treat with standard rewarming (SR) techniques. We developed a rewarming method that is significantly faster than SR. Percutaneously placed femoral arterial and venous catheters were connected to the inflow and outflow side of a countercurrent fluid warmer to create a fistula through the heating mechanism (CAVR). ⋯ Both groups were similar in APACHE II, Injury Severity, and Acute Physiology scores, prewarming blood and fluid requirements, and incidence of coagulopathy. Hypothermia resolved in 39 minutes with CAVR vs. 3.23 hours with SR (p less than 0.001). This was associated with an improved survival after moderately severe injury (p = 0.04), and a significant reduction in blood and fluid requirements, organ failures, and length of ICU stay.

During 1987 and 1988, the trauma service at Hahnemann University Hospital, a level I trauma center, evaluated 1,875 consecutive patients. Four hundred ninety-seven consecutive computed tomographic (CT) scans were performed to evaluate intracranial trauma in the emergency department. These patients' records were reviewed to determine the adequacy of loss of consciousness, amnesia, Glasgow Coma Scale (GCS) score, and mechanism of injury in predicting intracranial findings. ⋯ Mechanism of injury directly influenced the incidence of neurosurgical intervention. Current bedside methods to evaluate patients for possible intracranial injury in our trauma patient population are inadequate. Emergency department CT scans should be performed on all patients referred to the trauma service with previously classified mild- or low-risk criteria for intracranial trauma, regardless of GCS score.

Multicenter Study Comparative Study Clinical Trial Controlled Clinical Trial
A field comparison of the pharyngeotracheal lumen airway and the endotracheal tube.
A prospective, sequential study compared ease of use and bag-valve ventilation delivered by an endotracheal tube (ET) with that of the pharyngeotracheal lumen airway (PtL) for 111 victims of cardiac arrest in the pre-hospital setting. The PtL airway was found to be significantly easier to use as measured by the time required to intubate the patient and the number of attempts to place the device. Arterial blood gas determinations were made on arrival at the hospital and repeated 15 minutes later. ⋯ No adverse effects were reported. We conclude that the ability of the PtL to deliver effective ventilation is comparable with that of the ET as measured by arterial PCO2. When the ET method of airway control cannot be achieved, the PtL airway offers an effective alternative.

The Abdominal Trauma Index (ATI) was designed to stratify patients with penetrating injuries, and has been used to classify patients with blunt trauma. The Injury Severity Score (ISS) was originally designed to stratify victims of blunt trauma, and it has also been used for victims of penetrating trauma. We attempted to validate the use of ISS and ATI for both penetrating and blunt trauma. ⋯ The ASC rate for gunshots was higher than that for stab wounds (11% vs. 2%; p less than 0.001). In the blunt group, an ATI value greater than 15 and an ATI value greater than 25 were associated with ASCs (p less than 0.01 and p less than 0.001, respectively). The association of ASCs and ISS was linear with increasing ISS in patients with blunt abdominal trauma.(ABSTRACT TRUNCATED AT 250 WORDS)
