FTCH is a recently developed material which consists of a collagen fleece containing fibrinogen, thrombin, and aprotinin integrated into its surface. FTCH is highly effective in sealing of tissues and in establishing hemostasis. We evaluated FTCH in experimentally produced liver (n = 6) and splenic (n = 12) injuries in 18 adult mongrel dogs. ⋯ We conclude the following: FTCH provides adequate hemostatic control of experimental liver and splenic injuries. FTCH has excellent tissue compatibility and can be applied easily and safely to hemorrhaging parenchymal wounds. It will not replace adequate surgical techniques, but could be useful as a quickly available and easily applicable hemostatic means in diffuse or acute bleeding of liver and spleen.

Three hundred eighty-eight of 7,283 (5.3%) admitted trauma patients underwent urgent thoracotomy. In 61 patients (15.7%), pulmonary or tracheobronchial injury prompted thoracotomy (11, blunt; 50, penetrating). Pulmonary hemorrhage necessitated thoracotomy in 54 patients (88.5%); tracheobronchial injury in five patients (8.2%). ⋯ Thirty-six patients (59.0%) underwent pneumonorrhaphy: one died of concomitant injuries. Five (8.2%) patients underwent tracheobronchial repair: one died of concomitant injuries. Pneumonectomy was uniformly fatal and should be a procedure of last resort in the treatment of pulmonary injury, as lobectomy and pneumonorraphy are better tolerated by these critically ill patients.

Comparative Study
Fat embolism in patients with an isolated fracture of the femoral shaft.
Analysis of basic pathophysiologic variables in fat embolism patients is often restricted by the complexity of the different injuries present in each individual patient. To avoid this problem we investigated the presence of the fat embolism syndrome in patients with an 'isolated' fracture of the femoral shaft. ⋯ They showed significantly higher initial temperatures, lower pulse rates, a progressive hemoglobin decrease, and a fracture localization more proximal (p less than 0.025) than the other patients in the nondecompressed group; they also showed significantly different pathophysiologic patterns from the patients in the decompressed group. Although the pathophysiologic mechanism of the onset of clinical fat embolism remains unclear, initial temperature elevations in combination with 'typical' fracture localization and fracture type appear to have a predictive value.

From 1981 through 1985, 220 consecutive patients with presumed vascular injuries in the lower extremities underwent operation at the Ben Taub General Hospital. More than 81% of injuries were due to penetrating wounds, and blunt and iatrogenic injuries accounted for the remainder. A preoperative emergency center arteriogram was performed in 63.2% of patients, and physical examination alone prompted operation in 36.8%. ⋯ Venous repair was most commonly accomplished by lateral venorrhaphy (48.8%), ligation (19.7%), or insertion of a conduit (18.1%). Postoperative infection in closed wounds, in wounds left open because of the magnitude of injury, and in adjacent fractured bone occurred in 13% of patients. Late amputations were necessary in only four patients, three of whom had infection as the cause.

We reviewed 144 consecutive patients with flail chest and/or pulmonary contusion between 1979 and 1984. The purpose was to analyze the factors adversely affecting morbidity and mortality. There were 97 males and 47 females, with an average age of 40 years +/- 18 S. ⋯ However, the mortality more than doubled when there was a combined pulmonary contusion and flail chest (42%). More than half of all deaths were directly attributed to central nervous system injuries with another third due to massive hemorrhage. Factors that were associated with a higher morbidity and mortality included severe associated thoracic injuries, a high ISS, the presence of shock, falls from heights, and the combination of pulmonary contusion and flail chest.
