Randomized Controlled Trial Multicenter Study Clinical Trial
Prehospital hypertonic saline/dextran infusion for post-traumatic hypotension. The U.S.A. Multicenter Trial.
The safety and efficacy of 7.5% sodium chloride in 6% dextran 70 (HSD) in posttraumatic hypotension was evaluated in Houston, Denver, and Milwaukee. Multicentered, blinded, prospective randomized studies were developed comparing 250 mL of HSD versus 250 mL of normal crystalloid solution administered before routine prehospital and emergency center resuscitation. During a 13-month period, 422 patients were enrolled, 211 of whom subsequently underwent operative procedures. ⋯ No anaphylactoid nor Dextran-related coagulopathies occurred in the HSD group. Although this trial demonstrated trends supportive of HSD in hypotensive hemorrhagic shock patients requiring surgery, a larger sample size will be required to establish which subgroups of trauma patients might maximally benefit from the prehospital use of a small volume of hyperosmolar solution. This study demonstrates the safety of administering 250 mL 7.5% HDS to this group of patients.

Randomized Controlled Trial Clinical Trial
Management of penetrating colon injuries. A prospective randomized trial.
Fifty-six patients with penetrating colon injuries were entered into a randomized prospective study. Management of the colon injury was not dependent on the number of associated injuries, amount of fecal contamination, shock, or blood requirements. Twenty-eight patients were treated with primary repair or resection and anastomosis and 28 patients were treated by diversion (24 colostomy, 3 ileostomy, 1 jejunostomy). ⋯ This included one wound infection, two positive blood cultures, and three intra-abdominal abscesses. There were no episodes of suture line failure in the primary repair/anastomosis group. The authors conclude that, independent of associated risk factors, primary repair or resection and anastomosis should be considered for treatment of all patients in the civilian population with penetrating colon wounds.

Randomized Controlled Trial Clinical Trial
Cholangiocarcinoma complicating primary sclerosing cholangitis.
Cholangiocarcinoma is more likely to develop in patients with primary sclerosing cholangitis. Our aims were to describe the clinical presentation, course, and management of patients afflicted with both cholangiocarcinoma and primary sclerosing cholangitis and to estimate the prevalence of cholangiocarcinoma in patients with primary sclerosing cholangitis. A retrospective analysis was conducted of 30 patients with both primary sclerosing cholangitis and cholangiocarcinoma managed at our institution during an 8-year period. ⋯ Seventy patients with primary sclerosing cholangitis were followed prospectively in a clinical trial of medical therapy for an average of 30 months. Twelve patients died and five were found at autopsy to have cholangiocarcinoma. The potential for cholangiocarcinoma to develop in patients with primary sclerosing cholangitis may indicate that liver transplantation should be considered earlier in the course of the disease.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of conservative versus early excision. Therapies in severely burned patients.
Early excision and grafting of small burn wounds is a generally accepted treatment. Early excision of burn injuries greater than 30% total body surface area (TBSA) in adults, however, has not been universally accepted. In this study, 85 patients whose ages ranged from 17 to 55 years with greater than 30% total body surface area (TBSA) burns were randomly assigned to either early excision or topical antimicrobial therapy and skin grafting after spontaneous eschar separation. ⋯ No differences in mortality could be demonstrated between therapies in adult patients older than 30 years of age or with a concomitant inhalation injury. Children (n = 259) with similar large burns treated by early excision showed a significant increase in mortality with increasing burn size and with concomitant inhalation injury (p less than 0.05). The mean length of hospital stay of survivors was less than one day per per cent of TBSA burn in both children and adults.

Hemodynamic and oxygen transport effects of pentastarch in burn resuscitation.
If nonprotein colloid plasma expanders could be demonstrated to be safe and efficacious in burn resuscitation, a significant cost benefit would result. This study was a randomized cross-over comparison of 500 ml of 5% albumin and 500 ml of 10% pentastarch, a new hydroxyethyl starch, in acute burn resuscitation. ⋯ Pentastarch is a promising plasma substitute for burn resuscitation; the effects of a 500 ml infusion are equal or superior to those of albumin. Further study is necessary to assess the safety of larger infusion volumes.
