August 27, 2026:
World War II was the first war for Americans where most of the casualties were from combat wounds and injuries rather than disease picked up while in the combat zone. World War II was medically revolutionary for two things. Antibiotics, like penicillin, and the quick availability of blood for badly wounded soldiers.
British doctors discovered antibiotics in the 1920s, but the United States could mass-produce these life-saving drugs. As for emergency blood supplies, Charles Drew, an African American MD, developed the techniques and practices that made it possible to get freeze-dried blood powder in sterile packets for civilian and military casualties. The powder was reconstituted with sterile water to make whole blood. This saved tens of thousands of lives during World War II and continues to do so in the 21st century. During and after the war, this powder was shipped long distances by ship, plane, and truck. Dr. Drew also organized nationwide blood collection and distribution networks, with the help of like-minded medical professionals.
Another 21st-century development was advances in emergency medicine, administered by civilian EMTs (Emergency Medical Technicians) or military combat medics, which have made huge strides. Now, new medical tech is coming in the form of band-aids or bandages for people with minor bleeding injuries like cuts or scrapes. Some people do not heal as quickly, and these minor injuries can take a long time to heal. The solution is the self-monitoring polymer band-aids or bandages. This smart bandage tech has completed animal testing and now faces up to a decade of human tests and development of larger bandages before it is generally available.
This smart bandage is worn for a week or two until the chronic bleeding is healed. The smart bandage consists of two parts. The most obvious part appears to be a disposable band-aid or bandage containing biosensors, electrodes, and hydrogel with medications, along with a device that delivers low-level electrical stimulation to speed healing. The second component is a flexible, reusable electronic patch that monitors the healing process by tracking temperature, pH, and other factors, allowing a doctor or medical technician to monitor healing. Each year, millions of people have slow-healing wounds, and the smart bandage is designed to speed healing.
The smart bandage builds on two decades of major advances in emergency and combat medicine. These new techs and procedures led to a reduction of combat deaths by more than half since 2003. This resulted from new treatments for wounds that previously had no battlefield treatment. That meant the victim would die before more extensive treatment could be applied. Chief among these were deep (abdominal or thigh) wounds where large arteries (like the abdominal aorta) were opened. When that happens, the victim bleeds to death in minutes.
There have been several new battlefield treatments for catastrophic injuries like this. The first appeared in 2013 as a belt placed on the abdomen and activated. A bladder inflates, which puts sufficient pressure on the abdominal aorta to stop the bleeding or reduce it enough to make it possible to get the casualty to a surgeon. The belt does not always work. This led, in 2014, to the introduction of another more thorough solution. This was XStat, a syringe-like device that injected nearly a hundred small cellulose sponges into deep wounds. The tiny sponges were infused with anti-bacterial and clotting chemicals that stop the most severe bleeding in 20 seconds or less. The latest version of XStat sponges also contains a material that can be detected by X-rays, allowing a surgeon to be sure all the tiny sponges are removed later.
While tourniquets have been around for thousands of years, these devices work only on limbs and not well enough when major arteries are extensively damaged. Preventing death from most other rapid blood loss situations was achieved with the development and widespread use of powders and granules that could quickly stop the bleeding. First (in 2004) came special bandages like the Chitosan Hemostatic Dressing (more commonly called HemCon). This freeze-dried substance caused rapid blood clotting and was incorporated into what otherwise looked like a typical battlefield bandage. This bandage greatly reduced bleeding, which had become the most common cause of death among wounded American troops. This device was a major breakthrough in bandage technology. Over 95 percent of the time, the HemCon bandages stopped bleeding, especially in areas where a tourniquet could not be applied. It did not work in extreme cases, especially when the abdominal aorta was involved. Medics followed HemCon with WoundStat powder to control bleeding that HemCon could not control. While medics and troops prefer the bandage-type device, there are situations where WoundStat (a fine granular substance) is a better solution (especially in the hands of a medic). Only the medics got packets (usually two) of WoundStat powder. That's because this is only needed for deep wounds and has a theoretical risk of causing fatal clots if it gets into the bloodstream.
WoundStat was one of many new medical tools for battlefield medicine that greatly increased the effectiveness of immediate medical care for troops, within minutes or seconds after they were hit. This effort consisted of three programs. First, they developed new medical tools and treatments that troops could be taught to use quickly and safely. This included stuff like HemCon. Then came the equipping of medics (about one for every 30 or so combat troops) with more powerful tools, so that troops were less likely to bleed to death or suffocate from certain types of wounds that are not fatal if treated quickly enough. Finally, the Combat Lifesaver program more than tripled the number of "medics" by putting selected soldiers through a 40-hour CLS (Combat Lifesaver) course in the most common medical procedures soldiers can perform to treat the most dangerous wounds they usually encounter. These CLS-trained soldiers were not medics, but they did make true emergency medical treatment more widely available in combat. In other words, CLS-qualified troops are sort of "medics lite," which is close enough if you are badly wounded and in need of some prompt medical treatment.
Over the last two centuries, major wars have produced significant improvements in medical care. This is what has happened since 2001, but at a much faster pace. For example, since September 11, 2001, over two million American troops went off to war and about two percent of them were killed or wounded. Only 12 percent of the 57,000 combat zone wounds were fatal, the lowest percentage in military history. This was largely due to major improvements in dealing with rapid blood loss from a major artery being severed and the increased speed with which complex medical care could be delivered to wounded troops. New medical technologies also made it possible to detect injuries (like brain trauma) that, in the past, were very difficult to detect and treat.
The Combat Lifesaver course teaches troops how to do things like insert breathing tubes and perform other emergency surgical procedures to restore breathing. The CLS troops have skills most likely to be needed in life-saving situations when a medic is not available. The additional emergency medical training and new emergency first aid gear (the "CLS bag") have saved hundreds of lives and reduced the severity of even more wounds. Enough troops have taken CLS training so that there is one for every 10-15 combat troops and one for every 20 or so support troops on convoy or security duty.
These developments also appealed to civilian emergency medical services, and many experienced combat medics left the military to work as EMTs, improving care for civilian accident victims. This was similar to what happened to the EMT field after the Vietnam War, when ambulance crews rapidly evolved from simply transporting accident victims with basic first aid to EMTs who could administer procedures previously handled only by doctors. This followed World War II, when wartime demands drove the mass production of newly developed antibiotics, sparking a revolution in surgical techniques.
