Randomized Controlled Trial Clinical Trial
High-dose antithrombin III treatment of severely injured patients: results of a prospective study.
Antithrombin III (AT III) treatment has been shown to reduce disseminated intravascular coagulation and to inhibit thrombin, which plays a central role in the activation of platelets and other inflammatory systems in conditions with severe inflammation. The objective of this study was to evaluate the influence of early and high-dose administration of AT III to patients with severe multiple injuries on the inflammatory response and outcome. ⋯ The early and high-dose administration of AT III to patients with severe blunt trauma appears not to attenuate the posttraumatic inflammatory response or to significantly improve outcome.

The gastric intramucosal pH (pHi) and gastric mucosal-arterial CO2 gap (GAP) estimate visceral perfusion and predict outcome. Threshold values of these variables for use during resuscitation, however, remain poorly defined. The purpose of this study was to develop clinically derived cutoffs for both pHi and GAP for predicting death and multiple organ failure (MOF) in trauma patients. ⋯ In trauma patients, the ability to predict death and MOF is maximized at values of pHi less than 7.25 and GAP greater than 18 mm Hg. These values represent clinically derived cutoffs that should be useful for evaluating the adequacy of intestinal perfusion during resuscitation.

Comparative Study
Lactated ringer's is superior to normal saline in a model of massive hemorrhage and resuscitation.
Previous models comparing normal saline (NS) with lactated Ringer's solution (LR) for resuscitation use only mild or moderate hemorrhage and do not address the clinical situation of massive hemorrhage and resuscitation (MHR). This work compares NS and LR by using a new rat model of MHR. ⋯ With moderate hemorrhage, NS and LR are equivalent, but in the setting of massive hemorrhage and resuscitation, significantly more physiologic derangement and mortality occurs with NS than LR. LR is superior to NS for use in massive resuscitation.
