Menstrual history in altitude chamber trainees.

Previous studies have determined a higher rate of altitude-induced decompression sickness (DCS) in women than in men. Women are reportedly at higher risk for developing DCS during menses. A study of menstrual history in women completing altitude chamber training without developing DCS has never been accomplished. The purpose of this study was to collect and analyze menstrual history in these women. Thirteen U.S. Air Force Aerospace Physiology Units participated in a USAF-approved survey for 1 year. After completing altitude chamber flights, data on age, day of menstrual cycle (DMC), birth control pill use (BCP), and mean durations of menstrual cycle and menses were collected. There were 508 responses analyzed. There was no differences between mean duration of menstrual cycle and menses in the Yes (Y) and No (N) BCP groups. Y and N BCP groups were equally distributed across the menstrual cycle. Women completing altitude chamber training without developing DCS appear to be evenly distributed across their menstrual cycle, with use of BCPs not affecting their susceptibility to DCS.

Hyperbaric oxygen therapy and combat casualty care: a viable potential.

Extreme interest exists among the United States and Soviet military forces regarding the efficacy of hyperbaric oxygenation (HBO) for the treatment of wartime casualties. Specific areas of potential usefulness include the treatment of chemical agent exposure, crush injuries, and burns with HBO. Future direction dictates immediate scientific and medical support for the use of this powerful treatment modality.

Type II altitude decompression sickness (DCS): U.S. Air Force experience with 133 cases.

Type II altitude-related decompression sickness (DCS), due to its wide spectrum of symptoms, is often difficult to diagnose. This difficulty sometimes leads unnecessarily to the permanent grounding of an experienced aviator. So that this condition could be better understood, a total of 133 cases of Type II altitude DCS (on file at the United States Air Force Hyperbaric Medicine Division, School of Aerospace Medicine, Brooks AFB, TX) were reviewed. Most cases (94.7%) followed altitude chamber training. The most common manifestation was joint pain (43.6%), associated with headache (42.1%), visual disturbances (30.1%), and limb paresthesia (27.8%). The next most common symptoms were, in order of decreasing frequency: mental confusion (24.8%), limb numbness (16.5%), and extreme fatigue (10.5%). Spinal cord involvement, chokes, and unconsciousness were rare (6.9%, 6%, and 1.5%, respectively). Hyperbaric oxygen treatment produced fully successful results in 97.7% of the cases. Only 2.3% of the cases resulted in residual deficit; no deaths occurred. A thorough knowledge of the differential diagnosis and predisposing factors is essential to narrow the margins of error in the diagnosis and prevention of decompression sickness in the operational or training environment. A recommendation for favorable consideration of waiver action for those aviators who suffered Type II DCS is presented. These recommendations are based on a unique classification of the severity of symptoms.
