Colloids are used clinically to minimize edema yet may have detrimental consequences on glomerular filtration. The purpose of this study is to assess the renal and hormonal effects of colloid supplementation in the fluid resuscitation of burn victims. ⋯ These findings illustrate that despite substantially increasing plasma volume, colloid infusions reduce glomerular filtration and may limit any associated diuresis. Furthermore, this study demonstrates that hormonal regulation of blood volume remains intact after moderate burn injury.

To determine the end result of patients who underwent delayed fasciotomy, i.e., more than 35 hours for an established lower limb compartment syndrome. ⋯ One patient died of multiorgan failure and septicemia. The remaining four patients required lower limb amputation, because of local infection and septicemia. The one late amputation was performed 6 months after the injury, because the patient was left with a functionless insensate foot. Where recognition of an established compartment syndrome is delayed for more than 8 to 10 hours, we propose that the traditional inevitable fasciotomy be reassessed.

We hypothesize that during severe normothermic hemorrhagic shock (HS), induction of profound hypothermic circulatory arrest (PHCA) of 60 minutes to allow repair of otherwise lethal injuries in a bloodless field, can be survived without brain damage. In previous dog studies, normothermic HS with mean arterial pressure (MAP) of 40 mm Hg for 30 minutes, followed by PHCA of 2 hours at brain (tympanic membrane) temperature of 5 to 10 degrees C and core temperature of 10 degrees C, induced and reversed with cardiopulmonary bypass, resulted in survival with mild histopathologic brain damage. This study was designed to determine the severity of HS that can safely allow 1 hour of PHCA. In pilot studies with HS at MAP 30 mm Hg for 90 minutes with or without subsequent PHCA of 60 minutes there were no survivors. ⋯ The critical level of hypotension during 60 minutes normothermic HS that is compatible with survival in dogs is a MAP of between 30 and 40 mm Hg. After otherwise survivable severe normothermic HS of 60 minutes, PHCA of 60 minutes does not add brain damage or mortality, and may allow survival from injuries that would otherwise be irreparable.

To evaluate te feasibility of retrospectively creating a data base useful in trauma systems evaluations. ⋯ Linking records to create the study data base was arduous and could not be practically accomplished on a large scale or on a continuing basis. Because of the growing emphases on trauma system evaluations and outcomes beyond survival at acute care discharge, we recommend the routine inclusion of rehabilitation data in hospital-based trauma registries.
