Randomized Controlled Trial Comparative Study
An evaluation of two tourniquet systems for the control of prehospital lower limb hemorrhage.
Hemorrhage remains the main cause of preventable death on the modern battlefield. As Improvised Explosive Devices in Afghanistan become increasingly powerful, more proximal limb injuries occur. Significant concerns now exist about the ability of the windlass tourniquet to control distal hemorrhage after mid-thigh application. To evaluate the efficacy of the Combat Application Tourniquet (CAT) windlass tourniquet in comparison to the newer Emergency and Military Tourniquet (EMT) pneumatic tourniquet. ⋯ This study demonstrates that the CAT tourniquet is ineffective in controlling arterial blood flow when applied at mid-thigh level. The EMT was successful in a significantly larger number of participants.

Randomized Controlled Trial Multicenter Study
Fluid lavage of open wounds (FLOW): a multicenter, blinded, factorial pilot trial comparing alternative irrigating solutions and pressures in patients with open fractures.
Open fractures are an important source of morbidity and are associated with delayed union, nonunion, and infection. Preventing infection through meticulous irrigation and debridement is an important goal in management, and different lavage fluids and irrigation techniques (e.g., high- or low-pressure lavage) have been described for this purpose. However, there are a limited number of randomized trials comparing irrigating solutions or irrigating technique. We compared the use of castile soap versus normal saline and high- versus low-pressure pulsatile lavage on the rates of reoperations and complications in patients with open fracture wounds. ⋯ The fluid lavage of open wounds pilot randomized controlled trial demonstrated the possibility that the use of low pressure may decrease the reoperation rate for infection, wound healing problems, or nonunion. We have demonstrated the desirability and feasibility of a definitive trial examining the effects of alternative irrigation approaches.
