Title: [abstract] MANIFESTATION OF DECOMPRESSION ILLNESS IN DIVERS USING DIVE COMPUTERS.
Author: Dear, GdeL; Denoble, PA; Vann, RD
Abstract: The symptoms and other parameters from 1825 decompression illness (DCI) case reports in the Divers Alert Network database (1987-91) have been analyzed comparing the manifestations of DCI. These were subdivided into two groups, those who used Dive Computers (CD) and those who did not (Table divers-TD). The number of reports from divers using CD has increased over the years to 45.6% in 1991. In the CD group there were more experienced, older and male divers. The average dive profile of CD users was deeper, of longer duration and consisted of more repetitive dives. A combination of the most commonly presenting symptoms as well as those which reflected more serious injury were examined [table] % of CD users, % of T Divers; Pain: 68.71, 60.53; Numbness: 51.99, 56.69; Weakness: 23.77, 26.85; Paralysis: 4.45, 7.50; Dizziness: 19.33, 22.68; Visual Disturbance: 7.98, 6.31; Bladder problems: 2.30, 2.56; DCI Type I: 26.69, 17.14; DCI Type II: 65.80, 63.60; AGE: 7.52, 19.27; Residual Pain: 22.70, 14.83; Residual Neurological: 25.31, 28.99 [end table] Neurological symptoms predominated in both groups but were more common in TD, while limb pain only was more frequent in CD. AGE was diagnosed more often in TD. Onset times for the more serious symptoms were shorter than for pain or numbness. Residual symptoms after treatment were present in 48% of CD. A prospective study which includes safe dives as well as DCI is required to show the significance of these differences as well as the true incidence of DCI in DC users. The information presented here confirms the ubiquity of neurological symptoms in DCI in Sport Divers. It also indicates there are differences in the type of injury, time course and outcome suffered by divers using CD or Tables.
