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

The significance of new vaccines is obvious. New vaccines allow humans to be made resistant to more potential killers. The Army currently has three new vaccines in its sights, one each for malaria, norovirus, and dengue.

A proposed malaria vaccine would have cut down on the 198 million cases and 500,000 deaths in 2013. Average people will get norovirus five times in their life without a vaccine, causing diarrhea and vomiting. Dengue is mosquito-borne and starts off as a mild fever but can become severe, sometimes leading to death.

8. Better skull implants

Following brain trauma or damage to the skull, some patients have to have a portion of skull removed and later replaced by an implant made of titanium or polymers. Currently, these implants are prone to infection.

The Navy is looking to reduce the number of infections after implantation by developing new surface materials that have different textures and nano particle coatings that release chemicals to prevent infection. This would reduce the number of follow-up surgeries a patient would need and lower recovery time.
