Compared to previous American conflicts U.S. military medicine drastically reduced the number deaths due to injury during the wars in Iraq and Afghanistan. But that success doesn’t mean the profession is done innovating. Here are eight ways military medicine is trying to improve the ability to save lives:
1. Wound-stabilizing foam that reduces bleeding
Bleeding out is still the number one killer on the battlefield, according to the U.S. Army Institute of Surgical Research. So, DARPA has worked multiple programs to treat this major killer in combat.
One program success is ClotFoam. The foam works by seeking out damaged tissue, especially cut tissue fibers, and binding to it. It forms a scaffold that the body’s natural clotting agents can then latch to as they would with a cotton bandage. Different formulations of ClotFoam have been tested with the best reducing blood loss in mice by 66 percent when compared to a control group. DARPA is now looking to test delivery mechanisms for ClotFoam.
Another DARPA project was originally aimed at studying and accelerating the clotting process, but a project participant created foam that could treat abdominal injuries on its own. Now, DARPA is seeking help testing the Wound Stasis System device and foam in FDA trials so it can be sent to combat medics as well as civilian EMTs. As seen in the video above, the foam fills the abdominal cavity, stops the internal bleeding, and can be quickly removed by surgeons when the patient arrives at the hospital.
2. Remote trauma care
Telemedicine is not a new concept. The civilian medical sector has been working on remote patient care since the late ’70s, and many patients can now see their doctor via the internet when they can’t come into the office. The Army is looking expand its remote medicine options, most notably in the area of medical evacuation.
The Army wants systems that can be mounted inside vehicles and hooked up to existing radios, allowing patient information to go directly to the doctor who will receive them at the hospital. The doctor will also be able to call to the medic, advising on treatment while the patient is evacuated off the battlefield. This could allow for better care for patients en route to the hospital as well as a smoother handoff between the medic and the doctor. Prototypes have already been tested.
3. A chair that monitors vitals
Of course, beaming the information from patients to doctors with telemedicine is great, but currently it would require a medic to speak or type the information into a computer. The Army is looking to take that task off medics’ hands by adapting the LifeBed into a chair for military air and ground ambulances. The chair would track patients’ respiratory and heart rates and alert a medic if they showed signs of trouble. The medic would be able to spend less time checking on already stable soldiers and more time treating new patients as they evacuate casualties.
