Martial arts move could be a life-saver for trauma victims
SEATTLE, Wash. — A new University of Washington pilot-study is suggesting that a jiu-jitsu move could be an effective tool to stop blood loss in trauma victims.
The study, fronted by associate professor of emergency medicine at University of Washington School of Medicine Dr. Nathan White, says that the use of a maneuver called the “knee-mount” can be used for an average 70 percent blood flow reduction in the groin, shoulder or abdomen.
The move would put the body weight of the first-responder onto the injury site to restrict blood flow, using the knee.
White and his cohorts cite in their paper that a pre-hospital civilian can experience a 14 minute time lapse before a tourniquet is applied by trained paramedics. A traditional tourniquet generally takes 60 to 87 seconds to administer, and the research suggests that 1 liter of blood can be lost per minute from the femoral artery.
He says the knee-mount may be a solution to quicker response time to slow blood-loss. However, White says the study has limitations as well as next steps to explore for follow-up.
The study used healthy, uninjured subjects to demonstrate blood-flow restriction, and the study did not focus on iliac or axillary arteries. White also says that the maneuver should also be studied in comparison to traditionally compressing a wound using your hands, which outside studies have said can cause fatigue in the first-responder.
