目的探讨机械通气治疗危重症支气管哮喘的疗效。方法对2005～2011年我科收治的56例危重症哮喘患者进行气管插管机械通气治疗,观察上机前和上机后1h、12h、24h的pH值、PaO2、PaCO2和SaO2等动脉血气指标变化。结果 53例患者抢救成功,机械通气后PaO2、SaO2均明显升高,PaCO2明显降低,pH值明显改善,均具有统计学差异(P<0.01)。结论机械通气是治疗急性发作危重症哮喘的有效方法,值得临床推广。
Objective To investigate the curative effect of mechanical ventilation on critically ill patients with bronchial asthma. Methods 56 cases of critically ill asthmatic patients admitted to our department from 2005 to 2011 were treated with mechanical ventilation. The arterial blood gas indexes such as PaO2, PaCO2 and SaO2 at 1h, 12h and 24h after operation were observed. Variety. Results The rescue of 53 patients was successful. PaO2 and SaO2 were significantly increased after mechanical ventilation, PaCO2 was significantly reduced, pH value was significantly improved, with statistical significance (P <0.01). Conclusion Mechanical ventilation is an effective method for the treatment of acute asthmatic attacks and is worthy of clinical promotion.
