McCarty JC, et al. - Researchers examined the efficacy of the Bleeding Control Basic course with respect to training individuals to apply commercial tourniquets other than the type illustrated in the course and to improvise a tourniquet. In this non-blinded, crossover, sequential, randomized clinical trial with internal control, the investigators evaluated a volunteer sample of laypeople (n=102) who attended a B-Con course at Gillette Stadium and the Longwood Medical Area in Boston, MA, on the application of five different tourniquets sequentially. Participants less frequently applied any 1 of the 3 commercial tourniquets correctly, or improvised a tourniquet, compared with the tourniquet taught in the course. These findings suggested the insufficient translatability of the Bleeding Control Basic principles for correct Combat Application Tourniquet application to other commercial or improvised tourniquet types.
