[Clinical effect of hyperbaric oxygen therapy on groupment acute carbon monoxide poisoning].

OBJECTIVE: To summarize the clinical experience of hyperbaric oxygen therapy in the patients with groupment acute carbon monoxide poisoning. METHOD: 172 patients with acute carbon monoxide poisoning were received hyperbaric oxygen therapy besides some other regular therapies from january 2007 to december 2011. The clinical effect were analyzed retrospectively. RESULTS: 160 patients were cured (93%), 12 cases improved (7%), the total effective rate was 100%. The cure rate of the patients with hyperbaric oxygen therapy within 6 hours after the poisoning for 100% (115/115), It was significantly higher than that of patients treated for more than 6 hours [The cure rate was 78.9% (45/57)], The difference was statistically significant (P < 0.05). CONCLUSION: Treated by hyperbaric oxygen therapy early enough in the patients with acute carbon monoxide poisoning, can prevent or reduce the occurrence of delayed encephalopathy, decreasing disability and mortality.
