Title: [abstract] FLYING AFTER RECOMPRESSION THERAPY
Author: Vann, RD; Freiberger, JJ; DeNoble, PJ; Dovenbarger, JA; Nord, D; Winkler, P; Marroni, A
Abstract: INTRODUCTION: Does flying after recompression therapy for decompression illness (DCI) predispose to relapse. How long should treated divers wait before flying? METHODS: A 5-question survey was sent by e-mail to 248 chambers in October 2003. A 9-question diver survey was posted on the DAN Website (www.DiversAlertNetwork.org) in November 2003. RESULTS: Chamber survey. 17 chambers have responded to date. 4.5percent of 332 treated divers relapsed. Three divers who relapsed during or after flight flew after waiting 14 hrs, 3 days, or 10 days. How many flew without relapse is unknown. 14 chambers reported a median recommended wait for DCS-I of 3 days (range 1-7). 4 chambers reported a median wait for DCS-II of 5 days (range 2-7). Diver survey. 132 divers have responded to date. 11 were dropped due to questionable DCI diagnosis. Many misunderstood or did not complete some questions. Of 79 divers who did not fly, 35percent relapsed. Of 41 who flew, 31percent relapsed. The difference was not significant (chi-square). Differences in pre-relapse symptom severity were not significant (logistic regression). 39 divers received time-to-fly recommendations from their treatment chambers (median 3 days, range 1-30 days). There were no significant differences between these (ANOVA and Kruskal-Wallis) and reported times to fly for 9 relapsing divers (median 3 days, range 0.8-13 days) and 29 who did not relapse (median 4 days, range 0.5-30 days). 80percent of chamber-recommended delays to flight or actual times to flight were within six days. DISCUSSION: The available data did not indicate that flying after treatment predisposed to DCI relapse or that a delay of many weeks before flying was frequently needed. Relapse due to flying after treatment alone did not appear common. These tentative conclusions require confirmation.
