Clinical Trial
Oral contrast is not necessary in the evaluation of blunt abdominal trauma by computed tomography.
The administration of oral contrast (OC) is widely recommended for computed tomography (CT) of the abdomen in patients with blunt trauma. The purpose of this study was to determine whether routine abdominal CT scans performed without OC were associated with diagnostic error in patients with blunt trauma. Four hundred ninety-two patients were identified from our Trauma Registry who had CT scans for the evaluation of blunt abdominal trauma between January 1988 and December 1991. ⋯ There were 5 bowel injuries among the 42 patients who underwent an abdominal operation; in none would the use of OC have ensured the preoperative diagnosis. We found that the omission of OC did not represent a disadvantage to patients with blunt trauma undergoing a routine abdominal CT scan. Potential time delays and the hazards associated with the use of OC were minimized.

Inhalation injury predisposes burn patients to pneumonia, respiratory failure, and death, but the incidence and consequences of respiratory failure in the absence of inhalation injury are not well known. In a review of 529 burn patients admitted over a 4-year period, patients with inhalation injury had a 73% incidence of respiratory failure (hypoxemia, multiple pulmonary infections, or prolonged ventilator support) and a 20% incidence of adult respiratory distress syndrome (ARDS). In patients without inhalation injury, respiratory failure developed in 5% of patients and ARDS in 2% (both p < 0.001). ⋯ All patients who died had multiple organ failure. This review demonstrates that respiratory failure, regardless of its cause, frequently leads to multiple organ failure and death. Inhalation injury, in the absence of respiratory failure, does not appear to contribute to mortality.

Recent studies have shown that selective gut decontamination can reduce the incidence of pneumonia, but this does not decrease multiple organ failure (MOF) or mortality. These findings have prompted the hypothesis that pneumonia is an inconsequential symptom of MOF. To test this, we prospectively evaluated 123 high-risk trauma patients (mean Injury Severity Score = 36.2 +/- 1.5). ⋯ Of note, 10 (71%) of these patients died. Among the remaining 14 patients with MOF, 10 developed pneumonia, but this was associated with a minimal increase (less than or equal to 2) in MOF scoring (3 patients died). These data, by temporal association with MOF scoring, implicate pneumonia in precipitating or significantly worsening organ failure in 50% of the patients who developed MOF.

Clinical Trial
Preliminary report on videothoracoscopy in the evaluation and treatment of thoracic injury.
A prospective trial of videothoracoscopy was conducted at an urban trauma center between February 1992 and February 1993 to determine the efficiency of this less invasive method of evaluation and treatment. Twenty-four consecutive patients with chest trauma (penetrating, n = 22; blunt, n = 2) were examined thoracoscopically for clotted hemothorax that otherwise would have been treated with thoracotomy (n = 9), suspected diaphragmatic injury (n = 10), and continued bleeding (n = 5). To ensure maximal exposure, general anesthesia with a double-lumen endotracheal tube was used in each patient. ⋯ Intercostal artery injury was confirmed in all patients, and diathermy provided hemostasis in three patients without thoracotomy. No complications occurred. These data suggest the following: (1) Videothoracoscopy is an accurate, safe, and minimally invasive method for the assessment of diaphragmatic injuries, control of continued chest wall bleeding, and early evacuation of clotted hemothorax. (2) This technique should be used more frequently in patients with thoracic trauma. (3) Technical advances may expand the therapeutic role of thoracoscopy.

The year 1992 marked the 50th anniversary of one of the worst civilian disasters in American history. On November 28, 1942, fire destroyed Boston's Cocoanut Grove nightclub, killing 491 people and sending hundreds more to area hospitals. ⋯ In addition, the fire stimulated organization of burn care facilities, public safety legislation, and burn prevention. The history of the fire is reviewed, emphasizing its role in stimulating advances that formed some of the foundations of modern burn treatment.
