目的探讨短时间利巴韦林雾化吸入治疗毛细支气管炎的疗效。方法46例毛细支气管炎患儿随机分为治疗组24例、对照组22例,两组均予综合治疗,在此基础上治疗组将利巴韦林针剂稀释成20 mg/m l的浓度,氧气驱动雾化吸入,每次30 m in,每日4次,疗程5~7 d;对照组应用利巴韦林10~15 mg/(kg.d),静脉滴注,每日1次,疗程5~7 d。观察症状、体征变化,监测血气分析、血常规、肝功能。结果治疗组发热、咳嗽、喘憋、肺部哮鸣音及湿啰音消失时间均较对照组显著缩短(P<0.05);治疗1周后,治疗组血氧分压(SPO2)、血氧饱和度(SaO2)均显著高于对照组(P<0.05);治疗后两组红细胞数、血红蛋白含量均在正常范围,无肝功能异常,治疗组未见接触部位皮疹、未发现因雾化吸入使喘憋加重者。结论短时间利巴韦林雾化吸入治疗毛细支气管炎疗效确切,应用方便,安全无明显副作用,值得临床推广。
Objective To investigate the effect of ribavirin inhalation for treating bronchiolitis in a short time. Methods A total of 46 children with bronchiolitis were randomly divided into treatment group (n = 24) and control group (n = 22). Both groups were given comprehensive treatment. On the basis of this, the treatment group diluted ribavirin injection to a concentration of 20 mg / ml, oxygen Driven aerosol inhalation, each 30 m in, 4 times a day, the course of treatment 5 ~ 7 d; control group with ribavirin 10 ~ 15 mg / (kg.d), intravenous infusion, daily 1, 5 ~ 7 d. Observation of symptoms and signs changes, monitoring blood gas analysis, blood, liver function. Results The fever, cough, wheezing, wheezing of lung and the disappearance of wet rales in the treatment group were significantly shorter than those in the control group (P <0.05). After one week of treatment, the SPO2, (SaO2) were significantly higher than the control group (P <0.05); after treatment, the number of red blood cells and hemoglobin in the two groups were within the normal range, no abnormal liver function, the treatment group no contact rashes, found no inhalation due to inhalation Make wheezing aggravate those. Conclusion Ribavirin inhalation for a short time is effective in treating bronchiolitis. It is convenient and safe to use and has no obvious side effects. It is worthy of clinical promotion.
