Comparative Study
Abdominal packing for surgically uncontrollable hemorrhage.
Planned intra-abdominal packing for surgically uncontrollable hemorrhage from liver and retroperitoneal injuries exacerbated by hypothermia, acidosis, and coagulopathy regained popularity over the past decade. The authors reviewed 39 patients injured between August 1985 and September 1990; 31 packed for liver injuries, eight for nonliver injuries. The overall mortality rate was 44% (17/39); 9 (23%) exsanguinated, 3 (8%) died of head injuries, 3 (8%) of multisystem organ failure, 2 (5%) of late complications. ⋯ Intra-abdominal packing will not stop all bleeding; 23% of the patients exsanguinated. In 77%, packing helped achieve hemostasis we believed was not otherwise possible. Packing may be done to prevent the development of acidosis, hypothermia, and coagulopathy or may be done early in the treatment of cold, acidotic patients rather than massive transfusion in the face of surgically uncorrectable bleeding.

Several significant advances in the treatment of hepatic injuries have evolved over the past decade. These trends have been incorporated into the overall treatment strategy of hepatic injuries and are reflected in experiences with 411 consecutive patients. Two hundred fifty-eight patients (63%) with minor injuries (grades I to II) were treated by simple suture or hemostatic agents with a mortality rate of 6%. ⋯ Juxtahepatic venous injuries continue to carry a prohibitive mortality rate, but nonshunting approaches seem to result in the lowest cumulative mortality rate. Packing and planned reexploration has a definitive life-saving role when used adjunctively in the presence of a coagulopathy. Nonoperative management of select hemodynamically stable adult patients, identified by serial computed tomography scans after sustaining blunt trauma is highly successful (95-97%).

The triad of hypothermia, acidosis, and coagulopathy in critically injured patients is a vicious cycle that, if uninterrupted, is rapidly fatal. During the past 7.5 years, 200 patients were treated with unorthodox techniques to abruptly terminate the laparotomy and break the cycle. One hundred seventy patients (85%) suffered penetrating injuries and 30 (15%) were victims of blunt trauma. ⋯ Of 102 patients who died before reoperation 68 (67%) did so within 2 hours of the initial procedure. Logistic regression showed that red cell transfusion rate and pH may be helpful in determining when to consider abbreviated laparotomy. The authors conclude that patients with hypothermia, acidosis, and coagulopathy are at high risk for imminent death, and that prompt termination of laparotomy with the use of the above techniques is a rational approach to an apparently hopeless situation.

Recently there has been increasing concern over transfusion-related diseases, especially acquired immune deficiency syndrome (AIDS). The authors therefore investigated the efficacy of lactated Ringer's solution (LRS) alone as compared with blood plus LRS resuscitation on body weight change and mortality rate after severe trauma-hemorrhagic shock. Rats, 250 to 310 g (n = 85), had a midline laparotomy performed (i.e., trauma induced), the incision was closed, and a carotid artery, jugular vein, and femoral artery were cannulated. ⋯ Body weight gain was greater in group 2 compared with either of the other groups (p less than 0.05) on day 1 after hemorrhage because of edema, but no differences were seen on subsequent days. There were no differences in the survival of animals in the different groups. These results suggest that there should perhaps be a higher threshold for blood transfusion in the management of severe trauma-hemorrhagic shock than is currently practiced.

Comparison of amputation with limb-sparing operations for adult soft tissue sarcoma of the extremity.
The use of amputation in extremity soft tissue sarcoma has been decreasing at Memorial Sloan-Kettering Cancer Center (MSKCC) over the last 15 years. In an attempt to define the efficacy and future role of amputation in extremity soft tissue sarcoma, a prospective sarcoma database compiled at MSKCC from July 1982 to January 1990, consisting of 649 patients, was analyzed in a retrospective fashion. Ninety-two patients underwent amputation, and 557 had a limb-sparing procedure. ⋯ The prognosis of patients most likely to undergo an amputation for extremity soft tissue sarcoma (those with high-grade, large tumors) is not related to their local disease, but rather to the risk of distant metastases. Therefore, amputation in this cohort of patients can be recommended only when a limb-sparing procedure cannot achieve gross resection of tumor while still preserving a useful extremity, because amputation improves only local control and does not address distant disease. Further improvement in survival in this group of patients will be dependent on better systemic treatment for extremity soft tissue sarcoma, and not on more radical surgery.
