Abstract:
Hyperbaric oxygen (HBO) therapy for acute carbon monoxide (CO) poisoning is performed after oxygen therapy and breathing therapy. The usefulness of HBO therapy in emergency treatment has been reported. In this study, we examined the effectiveness of HBO for CO poisoning that was performed at our hospital over the past 5 years. Subjects were 23 patients who had HBO therapy for CO poisoning in the period January 2008-November 2013. The male to female ratio of the cases was 14:9 and the mean age was 54.6±20.8 years. The cause was suicide in 39.1% of cases and accident in 60.9%. The mean number of treatments was 5.4±6.8. The atmosphere absolute was 2ATA:2.8ATA=12:11. The ratio of direct conveyance of the patient to our hospital to indirect conveyance of the patient from another hospital was 15:8. The effectiveness of HBO therapy at the time of discharge was 73.9%. However, delayed neuropsychiatric sequelae (DNS) was detected in 3 of the 23 cases of CO poisoning. No correlations were found between elapsed time after CO inhalation and various blood parameters. However, time to start of therapy is important for DNS, and our results suggest that early treatment at a hospital with a hyperbaric chamber is necessary.
