C-17 Medevac mission, BaladAB, Iraq

Medevac mission, Balad Air Base, Iraq

US Air Force Expeditionary Aeromedical Evacuation Squadron members monitor patients during a C-17 aero-medical evacuation mission from Balad Air Base, Iraq, to Ramstein Air Base, Germany. The Boeing (formerly McDonnell Douglas) C-17 Globemaster III is a large American airlifter manufactured by Boeing Integrated Defense Systems, and operated by the United States Air Force, British Royal Air Force, the Royal Australian Air Force, and the Canadian Forces.[3] NATO and Qatar will also acquire the airlifter.
The C-17 Globemaster III is capable of rapid strategic delivery of troops and all types of cargo to main operating bases or directly to forward bases in the deployment area. It is also capable of performing tactical airlift, medical evacuation and airdrop missions. The C-17 takes its name from two previous United States cargo aircraft, the C-74 Globemaster and the C-124 Globemaster II.

As with many innovations in Emergency Medical Services (EMS), the concept of transporting the injured by aircraft has its origins in the military and the concept of using aircraft as ambulances is almost as old as powered flight itself.
The first written record of the term "air ambulance" is in Jules Verne's Robur le Conquérant (1866), which describes the rescue of shipwrecked sailors by an airship (balloon) named the Albatross. The first documented use of an air ambulance occurred during the Siege of Paris in 1870. when balloons were used to evacuate more than 160 soldiers from the besieged city.


During the Great War, the first true Air Ambulance flight was made when a Serbian officer was flown from the battlefield to hospital by a plane of the French Air Service. Records kept by the French at the time indicated that, if casualties could be evacuated by air within six hours of injury, the mortality rate among the wounded would fall from 60 per cent to less than 10 per cent - a staggering reduction!
During the First World War air ambulances were tested by various military organizations. Aircraft were still primitive at the time, with limited capabilities, and the effort received mixed reviews. The exploration of the idea continued, however, and by 1936 an organized military air ambulance service was evacuating wounded from the Spanish Civil War for medical treatment in Nazi Germany.
The first recorded British ambulance flight took place in 1917 in Turkey when a soldier in the Camel Corps, who had been shot in the ankle, was flown to a hospital in a de Havilland DHH within 45 minutes. The same journey by land would have taken 3 days to complete. In Britain, sick passengers were ferried by air from the Western Isles of Scotland to the mainland in the early 1930s. The first such flight to be recorded was on May 14, 1933 when a fisherman suffering from a perforated stomach, with consequent risk of peritonitis, was flown from Islay to Glasgow's Western Infirmary in a DH Dragon owned by Midland and Scottish Air Ferries.
In Switzerland, with the increasing interest in winter sports during the early post World War 2 years, the use of air ambulances evolved from the increasing difficulties experienced in mountain rescue work. Initially fixed-wing aircraft were used, landing medical teams with equipment as close as possible to the injured parties so that rapid first aid treatment could be applied prior to evacuation.
To overcome a lack of suitable landing sites close to the incident in mountainous regions, it was even at one stage proposed to parachute medical personnel with equipment and sledges into the rescue area. Although training was undertaken,  there is no documentary evidence to suggest that this technique was ever put into practice.
The first documented medevac by helicopter occurred during the second World War. In April 1944, a US Army Air Forces aircraft with three wounded British soldiers on board, was forced down in the jungle behind Japanese lines near Mawlu in Burma.A new US Army Sikorsky YR-4B helicopter, flown by Lt. Carter Harman, could carry only one passenger but, over 25-26 April 1944, four return trips were made.
Following the end of the Second World War, the first civilian air ambulance in North America was established by the Saskatchewan government in Regina, Saskatchewan, Canada. Back in the United States, 1947 saw the creation of the Schaefer Air Service, the country's first air ambulance service. Founded by J. Walter Schaefer, of Schaefer Ambulance Service in Los Angeles, Schaefer Air Service was also the first FAA-certified air ambulance service in the United States. Para-medicine was still decades away, and unless the patient was accompanied by a physician or nurse, they operated primarily as medical transportation services.
The first dedicated use of helicopters by U.S. forces occurred during the Korean War, during the period from 1950-1953. While popularly depicted as simply removing casualties from the battlefield (which they did), helicopters also expanded their services to moving critical patients to more advanced hospital ships once initial emergency treatment in field hospitals had occurred. On August 4, 1950, just one month after the start of the Korean War, the first rotorwing medical evacuation was performed with a bubble-fronted Bell 47 (as seen in the TV series M*A*S*H). The wounded were transported on basket stretchers attached to the top of the landing gear on the outside of the small helicopter (Figure 3-1). They were covered with blankets in a nearly futile effort to maintain body heat and prevent wound contamination. It is estimated that more than 20,000 injured soldiers were evacuated by helicopter. The World War II casualty/death rate of 4.5 deaths per 100 casualties dropped to 2.5 per 100 casualties during the Korean War. While there were some technological advances in medicine during that period, the improvement is largely attributed to use of the helicopter to evacuate patients to definitive care more quickly. The external litter, however, did not allow for medical care during transport.
The next major advance in AM transport occurred during the Vietnam War, where the Bell UH-1 helicopter was placed into operation. Affectionately known as the Huey, this aircraft was large enough to hold patients inside, where medical personnel could begin treatment during the flight to a field hospital. The mass deployment of these aircraft as medevac units reduced the average delay until treatment to one hour. The ability to carry patients inside the aircraft was a key element in the reduction of mortality and morbidity. Military medics performed procedures previously done only by physicians: they started central lines, inserted chest tubes, and sutured bleeding wounds. This care, coupled with the initiation of specialty hospitals for the treatment of different types of injuries, resulted in a reduction in the mortality rate to 1 death per 100 casualties.
The first known civilian application of a medical helicopter was in 1958 in Etna, California. Bill Mathews, a businessman, started a helicopter service to ferry patients for Dr. Granville Ashcraft, the town's only physician. The town druggist also used the helicopter to deliver drugs during emergencies.
By 1969, in Vietnam, the use of specially trained medical corpsmen and helicopters as ambulances led U.S. researchers to conclude that servicemen wounded in battle had better rates of survival than motorists injured on California freeways. This conclusion inspired the first experiments with the use of civilian paramedics in the world.
Two programs were implemented in the U.S. to assess the impact of medical helicopters on mortality and morbidity in the civilian arena. Project CARESOM was established in Mississippi in 1969. Three helicopters were purchased through a federal grant and located strategically in the north, central, and southern areas of the state. Upon termination of the grant, the program was considered a success and each of the three communities was given the opportunity to continue the helicopter operation. Only the one located in Hattiesburg did so, and it was therefore established as the first civilian air medical program in the United States. The second program, the Military Assistance to Safety and Traffic (MAST) system, was established in Fort Sam Houston in San Antonio in 1969. This was an experiment by the Department of Transportation to study the feasibility of using military helicopters to augment existing civilian emergency medical services. These programs were highly successful at establishing the need for such services.
Also, in 1969 the state of Maryland received a grant to purchase Bell Jet Ranger helicopters and started one of the nation's first medevac programs. The four helicopters, manned by paramedics, were strategically based throughout the state for quick response to emergency situations. When they were not carrying patients, the helicopters were used for law enforcement and traffic control.
On November 1, 1970, the first permanent civil air ambulance helicopter, Christoph 1, entered service at the Hospital of Harlaching, Munich, Germany. The first civilian, hospital-based medical helicopter program in the United States began operation in 1972. Flight For Life Colorado began with a single Alouette III helicopter, based at St. Anthony Central Hospital in Denver, Colorado. In Ontario, Canada, the air ambulance program began in 1977, and featured a paramedic-based system of care. The system, operated by the Ontario Ministry of Health, began with a single rotor-wing aircraft based in Toronto. An important difference in the Ontario program involved the emphasis of service. 'On scene' calls were taken, although less commonly, and a great deal of the initial emphasis of the program was on the interfacility transfer of critical care patients.
Mercy Flight WNY was established by Douglas H. Baker in 1981 as the first air-medical service in New York State and one of the first in the country.  From day one, Mercy Flight WNY has maintained its independence of any hospital and is currently one of only a handful of remaining not-for-profit providers.  The majority of other US programs are operated by either for-profit organizations or hospitals.  (Right: Patient being loaded in the early 80's.  Paramedic on left  Margaret Ferrentino, was first female paramedic in NY State and is current Mercy Flight Vice-President/CFO.)
Helicopters continue to play a vital role in miltary medevacs.  UH-60 Blackhawk helicopters have been used extensively in Iraq and Afganistan to medevac wounded soldiers from the battlefield.  While both countries feature harsh desert environments that take their toll on helicopters, Afganistan's mountain peaks as high as 18,000 feet further complicate the mission. Because of the vast, mountainous terrain, evacuating casualties often extends beyond what doctors call the "golden hour": that crucial 60 minutes during which a traumatically-injured person has to reach a hospital before their survival chances plummet. So medics have begun doing emergency procedures inside helicopters that would normally wait for ER doctors.
The United States has some 200 operations whose services are paid for primarily by the patients and their insurance companies. As well as Switzerland, France, Austria, Italy Scandinavia and the former West Germany all have very successful versions of the helicopter-based EMS, the benefits of which have in some instances been particularly well-documented.
In Germany for example, there is now a network of helicopters which has evolved over the past twenty years to cover the entire country. Statistics which have been gathered over this period of time show:
  • An average response time to the scene of the incident of just 10 minutes.
  • Intensive care stays in hospital have been shorted by between five and seven days.
  • There are 9% fewer wound infections.
  • A significant reduction in the number of deaths during transport to hospital.
  • Head injury mortality has been reduced by 15%.
