Life-threatening bleeding requires prompt reversal of the anticoagulant effects of factor Xa inhibitors. This study investigated the effectiveness of four-factor prothrombin complex concentrate in treating trauma-related hemorrhage with rivaroxaban-anticoagulation in a pig polytrauma model. This study also tested the hypothesis that the combined use of a low dose of prothrombin complex concentrate plus tranexamic acid and fibrinogen concentrate could improve its subtherapeutic effects. ⋯ Prothrombin complex concentrate effectively reduced blood loss, restored hemostasis, and balanced thrombin generation. A multimodal hemostatic approach using tranexamic acid plus fibrinogen concentrate enhanced the effect of low doses of prothrombin complex concentrate, potentially reducing the prothrombin complex concentrate doses required for effective bleeding control.

The Solubility of Halothane in Blood and Tissue Homogenates. By Larson CP, Eger EI, Severinghaus JW. Anesthesiology 1962; 23:349-55. ⋯ Calculated partition coefficients ranged from 0.7 for water to 2.3 for blood and from 3.5 for human or bovine kidney to 6 for human whole brain or liver and 8 for human muscle. Human peritoneal fat had a value of 138. The human blood-gas partition coefficient of 2.3 as determined by this equilibration method was well below the previously published value of 3.6.
