In patients with inferior vena cava (IVC) injuries, predictors of survival are investigated. From 1987 to 1995, 27 IVC injuries were identified among 514 patients with vascular trauma. The ability of clinical determinants to predict survival were retrospectively assessed. ⋯ Four complications [venous hypertension (n = 2), IVC thrombosis (n = 1), and pulmonary embolus (n = 1)] occurred in the 14 survivors (28.6%). Blunt injury, revised trauma score, free perforation, injury location, intraoperative hypotension, and blood loss were predictive of mortality. IVC injuries remain extremely lethal, and improved survival is associated with infrarenal penetrating injuries and a contained hematoma.

Since 1990, a selective management algorithm has been used in our Trauma Center to treat 91 patients with penetrating neck injuries. Group A (n = 37) sustained zone I, zone III, or multiple-zone injuries; Group B (n = 54) sustained zone II injuries [most (55, 66.4%) from gunshot or shotgun wounds]. Nineteen Group A and 21 Group B patients required mandatory neck exploration. ⋯ Unnecessary exploration was avoided in 52 per cent of cases regardless of the location of the wound. Mortality and morbidity rates were acceptable. Patients with penetrating neck injuries could be safely managed selectively regardless of the injury zone.

Primary repair of 58 consecutive penetrating injuries of the colon: should colostomy be abandoned?
Although primary repair of penetrating colon injuries in patients with low injury severity is now widely accepted, several "risk factors" continue to be viewed as relative contraindications to this method of management. The purpose of this study was to evaluate the septic complications and leak rate in a series of consecutive penetrating colon injuries managed exclusively with primary repair. The records of 58 consecutive patients with penetrating intra-abdominal colon injuries managed at an urban Level I trauma center from July 1991 to December 1995 were reviewed. ⋯ The presence of "risk factors" appeared to identify more severely injured patients as indicated by a higher mean PATI score and a higher incidence of intra-abdominal abscess, when compared to patients in whom the "risk factor" was absent. Primary repair can safely be used for virtually all penetrating colon injuries, as clinical leaks are rare, even in patients with "risk factors". Intra-abdominal abscess and other septic complications are dependent on the overall severity of the intra-abdominal injuries and probably result from contamination occurring at the time of injury rather than from postoperative leak from the primary repair.

Comparative StudyRandomized blinded study of aprotinin infusion for liver crush injuries in the pig model.
Repeat exploratory laparotomies for intra-abdominal bleeding in patients who sustain severe blunt intra-abdominal trauma are common. Reexploration usually reveals no single site of bleeding and the abdomen is closed with laparotomy pad packing, with a presumed diagnosis of coagulopathy. ⋯ The liver plays a major role in the balance of hemostatic systems, and this balance is disrupted by liver trauma. This study investigates the use of intravenous aprotinin, a naturally occurring serine protease inhibitor, in a pig liver crush model to evaluate its effectiveness in reducing intra-abdominal bleeding in experimentally induced shock and non-shock states.

The purpose of this review is to investigate the utility of autotransfusion in trauma patients in the past 3 years. A retrospective review was conducted of the charts for whom the Haemonetics Cell Saver autotransfusion device (Haemonetics Corp., Natick, MA) was utilized between January 1, 1993, and December 31, 1995. The estimated blood loss and quantity of blood transfused were noted for abdominal trauma patients. ⋯ The use of salvaged autologous blood comprised 45 per cent of total blood transfused. On a case-by-case basis, 75 per cent of cases were cost-effective compared to blood bank costs for an equivalent transfusion. Transfusion of intraoperatively salvaged autologous blood (autotransfusion) is a cost-effective, efficient way to provide blood products to operative trauma patients.
