急诊抢救重症哮喘合并呼吸衰竭32例临床效果分析

目的：探讨急诊无创机械通气在抢救重症哮喘合并呼吸衰竭中的应用价值。方法将2012年9月~2013年9月本院收治的32例重症哮喘合并呼吸衰竭患者分为试验组（17例，常规治疗基础上再加用无创机械通气）和对照组（15例，仅给予常规治疗），比较两组治疗前后血pH、动脉血氧分压（Pa02）、动脉血二氧化碳分压（PaC02）改变及哮喘缓解率。结果①治疗12 h后，试验组哮喘缓解率达到64.71%，明显高于对照组46.67%（P〈0.05）；②经治疗12 h后，两组患者血pH、Pa02、PaC02均得到不同程度的改善，但试验组较对照组改善更为显著，差异有统计学意义（P〈0.05）。结论无创机械通气用于急诊抢救重症哮喘合并呼吸衰竭效果显著，值得临床推广应用。

Clinical analysis of non-invasive mechanical ventilation in rescuing 32 cases of severe asthma and respiratory failure

Objective To investigate the application of non-invasive mechanical ventilation in rescuing severe asthma with respiratory failure.Methods 32 patients with severe asthma and respiratory failure into our hospital from September 2012 to September 2013 were divided into experimental group（17 cases, were given were given non-invasive mechanical ventilation besides routine remedies） and control group（15 cases,were only given the same routine remedies）, the pH of blood, arterial oxygen tension（PaO2）, arterial carbon dioxide tension（PaCO2） and asthma remission rate of two groups were compared.Results ①After 12 hours of treatment,the asthma remission rate of experimental group was higher than that of control group（P〈0.05）;②After 12 hours of treatment, the pH of blood, PaO2, PaCO2 of two groups had been improved, while experimental group were significantly more improvement than control group（P〈0.05）.Conclusion There is a significant effect of non-invasive mechanical ventilation in rescuing severe asthma with respiratory failure, which is worthy of clinical promotion.
