Title: [abstract] PREDICTORS OF LONG TERM NEUROLOGICAL SEQUELAE IN RECREATIONAL DIVERS.
Author: Dear, GdeL; Corson, K; Dovenbarger, JA; Moon, RE; Bennett, PB
Abstract: The Divers Alert Network (DAN) database contains the details of 1384 cases of decompression illness in recreational divers from 1987-1990. Mean age was 35.3 years (range 15-71 yrs). Analysis revealed 396 divers who had neurological sequelae (NLS) post treatment, 128 for more than 3 months. Symptoms are defined as; mild (severity code+ 1-3), severe (severity code 4-6). NLS were counted as present at the end of recompression treatment (NLS End HBO)and 290 days (NLS 3months). (table) No NLS, NLS End HBO, NLS 3months; n=988, n=396, n=128; Mean Severity Code: 3.71, 4.28***, 4.5***; Median delay to Rx(hr): 22(1-4110), 21(1-2376), 17 (1-2376); USN TT6 use %: 58.7, 58.5, 58.6; Male divers %: 77.3, 68.6, 69.5; O2 prior to HBO %, 29.3, 29.3, 31.3; Progressive symptoms %: 68.1, 68.6, 70.3; Age >40 %: 20.3, 30.6**, 31.9**; Symptom onset <10 min %: 39.8, 47.5*, 55.5***; Compared with no NLS: * p <=0.05, **p<=0.01, ***p<=0.001 +Severity Code Appendix Report Diving Accidents and Fatalities,Divers Alert Network 1991. There was no significant relationship between the following and NLS: delay from onset to recompression, use of USN TT6, gender, use of 02, temporal progression of symptoms and history of previous decompression illness. Severity of symptoms, age over 40 years and short latency of onset were risk factors for NLS. Age and latency were still significant when corrected for severity.
