目的：探讨高频振荡通气联合蛇毒血凝酶治疗新生儿肺出血的疗效。方法选取2013年3月～2015年3月于我院进行治疗的新生儿肺出血患者70例，随机分为观察组和对照组各35例，对照组采取常规治疗及高频振荡通气，观察组在对照组的基础上加用蛇毒血凝酶治疗，对比两组患者的临床疗效。结果观察组患者肺出血停止时间、HFOV治疗时间、住院时间均小于对照组，观察组治疗的总有效率明显高于对照组，(<0.05)。结论高频振荡通气联合蛇毒血凝酶治疗新生儿肺出血疗效显著，安全性高，值得临床推广。“,”Objective To investigate the effect of high frequency oscillatory ventilation combined with snake venom blood coagulation in the treatment of neonatal pulmonary hemorrhage.Methods 70 cases of neonatal pulmonary hemorrhage treated in our hospital were randomly divided into observation group and control group,cases were randomly divided into observation group and control group with 35 cases in each group,the control group was treated with routine treatment and high frequency oscillation ventilation,and the clinical efficacy of the two groups was compared with that of the control group.Results The stopping time of pulmonary hemorrhage,the time of HFOV treatment and hospitalization time in observation group were less than those in control group,the total effective rate of observation group was significantly higher than that in control group (P<0.05). Conclusion High frequency oscillatory ventilation combined with snake venom blood coagulation in the treatment of neonatal pulmonary hemorrhage is significant,safe and worthy of clinical promotion.
