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.

Case Reports
Limb salvage versus traumatic amputation. A decision based on a seven-part predictive index.
In severe traumatic injuries to the lower extremity, it is often a difficult decision to attempt heroic efforts aimed at limb salvage or to amputate primarily. To answer this question, the authors performed a 5-year review of 70 limbs in 67 patients. Patients were identified as presenting with major lower extremity trauma and an associated arterial injury. ⋯ All 51 patients with an LSI score of less than 6 had successful limb salvage (p less than 0.001). All 19 patients with an LSI score of 6 or greater had amputations (p less than 0.001). Although statistics cannot replace clinical judgment, this index can be a valuable objective tool in the evaluation of the patient with a severely traumatized extremity.

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.
