Hyperbaric oxygen therapy in acute carbon monoxide poisoning with delayed encephalopathy:A clinical ob- servation of 63 cases

Objective To investigate clinical effects in patients with delayed encephalopathy due to acute carbon monoxide poisoning.Methods Sixty three carbon monoxide poisoning in different stages(32 cases with mild type,21 cases with moderate type and 10 cases with severity type) with delayed encephalopathy underwent hyperbaric oxygen therapy at different time of pathogenesis,including less than 1 m,1～3 m and 3～6 m.The therapeutic effects were evaluated and analyzed.Results Hyperbaric oxygen therapy was applied average(16±4) times in 63 cases, and 28(44.4%) cases of them were recovered completely,21(33.3%) cases of them recovered significantly,9 (14.3%) cases of them recovered partially,and total effective rate was 92.0%.The more early received hyperbaric therapy,the more positive effects.Conclusion It demonstrated that early hyperbaric oxygen treatment would play an important role in preventing delayed encephalopathy caused by acute carbon monoxide poisoning.
