KISSIMMEE, Fl. –Naval Medical Research Center (NMRC) scientists presented their research, “Simulated aeromedical evacuation exacerbated histopathology and immunomodulation,” during the Military Health System Research Symposium (MHSRS) in Kissimmee, Florida August 22.
The hypothesis for their research on aeromedical evacuation examines how low encompassing (ambient) air pressure can negatively impact a wounded warfighter suffering from a serious organ injury.
According to Dr. Anke Scultetus, head of NMRC’s En-Route Care & Critical Care Research Program, Neuro-Trauma Department, this type of evacuation is often used as a rapid and effective way to transport severely injured warfighters.
”There is limited information available on the effects of aeromedical evacuation,” she said. “Wounded service members are of particular concern, since changes in cabin pressure, temperature, and constant vibration could aggravate or worsen their injury.”
Scultetus and her team used a test blast model, and a 12 hour simulated aeromedical evacuation two days after injury, which resulted in increased evidence of tissue damage to multiple organs, particularly the lungs, brain and intestines.
“The inflammatory response was modified in subjects exposed to blast followed by simulated aeromedical evacuation, suggesting the inflammatory response can be altered due to changes in the outside environment, including ambient pressure,” said Scultetus. “Our research suggests aeromedical evacuation has the potential to worsen long-term outcomes, and we have to consider current practices and re-evaluate our strategies to transport injured warfighters.”
“Similar to ambient air pressure, traumatic brain injury (TBI) increases inflammatory responses,” said Scultetus. “I recommend further studies are warranted to investigate the physiologic effects, and possibly reconsider our current practice with aeromedical evacuation.”
