To assess real-world effectiveness of hyperbaric oxygen therapy (HBOT) on
delayed neuropsychiatric sequelae (DNS) after carbon monoxide (CO) poisoning we
conducted a retrospective review of patients with CO poisoning admitted to
Linkou Chang-Gung Memorial Hospital, Taiwan's largest medical center, during
2009-2015. We included patients developing DNS after CO poisoning and compared
improvements in neuropsychiatric function, with and without HBOT, after
12 months post-DNS to understand differences in recovery rates. DNS
improvement-associated factors were also evaluated. We used receiver operating
characteristic (ROC) curve analysis to assess the role of time elapsed between
DNS diagnosis and HBOT initiation in predicting DNS improvement. A total of 62
patients developed DNS, of whom 11 recovered while the rest did not. Possible
factors predicting DNS improvement included receiving HBOT post-DNS (72.7% vs
25.5%; P = 0.006), and treatment with more than three HBOT sessions during acute
stage CO poisoning (81.8% vs 27.5%; P = 0.003). The relevant area under the ROC
curve was 0.789 (95% CI 0.603-0.974), and the best cut-off point was 3 days
post-DNS diagnosis, with 87.5% sensitivity and 61.5% specificity. Early HBOT in
patients who developed DNS after CO poisoning significantly improved their DNS
symptoms, with treatment effects sustained for 1 year after DNS diagnosis.
