RT Journal Article SR Electronic T1 High-altitude decompression illness: case report and discussion JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 803 OP 807 VO 169 IS 8 A1 G. Michael Allan A1 David Kenny YR 2003 UL http://www.cmaj.ca/content/169/8/803.abstract AB DECOMPRESSION ILLNESS (DCI) CAN OCCUR in a variety of contexts, including scuba diving and flight in nonpressurized aircraft. It is characterized by joint pain, neurologic injury, and respiratory or constitutional symptoms. To prepare flight crews for accidental decompression events, the Canadian Armed Forces regularly conducts controlled and supervised depressurization exercises in specialized chambers. We present the cases of 3 Canadian Armed Forces personnel who successfully completed such decompression exercises but experienced DCI after they took a 3-hour commercial flight 6 hours after the completion of training. All 3 patients were treated in a hyperbaric oxygen chamber. The pathophysiology, diagnosis and management of DCI and the travel implications for military personnel who have undergone such training exercises are discussed. Although DCI is relatively uncommon, physicians may see it and should be aware of its presentation and treatment.
