Studies have shown decreased mortality after improvements in combat casualty care, including increased fresh frozen plasma (FFP):red blood cell (RBC) ratios. The objective was to evaluate the evolution and impact of improved combat casualty care at different time periods of combat operations. ⋯ The combination of improved prehospital care, trauma systems approach, performance improvement projects, and improved transfusion or resuscitation practices have led to a 50% decrease in mortality for this critically injured population. We are now transfusing blood products in a ratio more consistent with 1 FFP to 1 RBC. Simultaneously, crystalloid use has decreased by 61%, all of which is consistent with hemostatic resuscitation principles.

Comparative Study
Carbachol alleviates rat cytokine release and organ dysfunction induced by lipopolysaccharide.
To observe the influence of carbachol on inflammatory cytokine release and its protective role on organ function in rat endotoxemia model, and, furthermore, to investigate its receptor mechanism in rat peritoneal macrophages in vitro. ⋯ The results suggested that both carbachol and nicotine play a role in the anti-inflammatory process and organ function protection through the α7 subunit of nicotinic cholinergic receptor.

Noncompressible hemorrhage from central vascular injuries remains the leading cause of preventable death in modern combat. This report introduces a large animal model of noncompressible torso hemorrhage, which permits assessment of the various approaches to this problem. ⋯ This study presents a large animal model of class IV hemorrhagic shock from noncompressible hemorrhage, which permits comparison of various vascular control methods to address this challenging problem. Future studies using this model as the standard will allow further development of strategies for the management of noncompressible hemorrhage.
