ABSTRACT
Objective To evaluate the prevention and treatment effect of butylphthalide injection in delayed encephalopathy after severe carbon monoxide poisoning(DESCMP).Methods One hundred and fiftyeight cases with severe carbon monoxide poisoning (SCMP) were randomly assigned to 2 groups.Observation group (n =83), butylphthalide treatment when SCMP was diagnosed;Control group (n =75), with no butylphthalide therapy.Incidence rate in 3 month, drug amount and the clinical effects of butylphthalide were observed.Results Observation group occurred 5 DEACMP, with the incidence rate of 6.58％, and control group occurred 14 cases,with the incidence rate of 18.67％ ,significant difference was observed in two groups(x2 =154.204,P＜0.05).There were also significant differences in the glasgow coma scale(14.00±1.89 vs.13.00 ±3.30,t =1.780, P＜ 0.05) and mini-mental state examination (26.20± 2.89 vs.19.57 ± 7.12, t =2.003, P＜0.05) between the two groups.Conclusion Early treatment with butylphthalide can decrease the incidence rate of DEACMP.
