Allison G. McNickle, Douglas R. Fraser, Paul J. Chestovich, Deborah A. Kuhls, and John J.  Fildes (all Medicine) evaluated if prehospital tourniquet application altered the initial transfusion needs in arterial injuries when compared with a non-tourniquet control group. The results of their study were published in the BMJ, one of the world's oldest peer-reviewed medical journals. Working at University Medical Center, the UNLV School of Medicine trauma surgeons looked at 192 patients with extremity arterial injuries at UMC from 2013-2017 and compared how patients who received prehospital tourniquets fared compared to those who did not, in terms of transfusions, morbidity, length of hospital stay, and mortality.
