目的探讨机械通气治疗重症支气管哮喘的临床疗效。方法选取2014年2月—2015年2月丰城市人民医院收治的重症支气管哮喘患者84例,随机分为对照组与试验组,各42例。对照组患者予以综合治疗,试验组患者在对照组基础上予以机械通气治疗。观察两组患者治疗前后动脉血气指标(SPO2、p H值、Pa CO2、Pa O2)、呼吸频率、心率、临床疗效及并发症发生情况。结果治疗前两组患者SPO2、p H值、Pa CO2、Pa O2、呼吸频率、心率比较,差异无统计学意义(P>0.05),治疗后观察组患者SPO2、p H值、Pa O2高于对照组,Pa CO2、呼吸频率、心率低于对照组,差异有统计学意义(P<0.05);试验组患者总有效率高于对照组,差异有统计学意义(P<0.05);两组患者均未发生严重并发症。结论机械通气治疗重症支气管哮喘的临床疗效显著,可改善患者临床症状,且并发症少。
Objective To investigate the clinical efficacy of mechanical ventilation in the treatment of severe bronchial asthma. Methods Eighty-four patients with severe bronchial asthma admitted from February 2014 to February 2015 in Fengcheng People’s Hospital were randomly divided into control group and experimental group, with 42 cases in each group. Patients in the control group were treated comprehensively, and patients in the test group were treated with mechanical ventilation on the basis of the control group. Arterial blood gas indexes (SPO2, p H, PaCO 2, Pa O 2), respiratory rate, heart rate, clinical efficacy and complications were observed before and after treatment in both groups. Results There was no significant difference in SPO2, p H value, PaCO 2, Pa O 2, respiration rate and heart rate between the two groups before treatment (P> 0.05). After treatment, SPO2 and p H values in the observation group were higher than those in the control group The PaCO 2, respiration rate and heart rate in the control group were lower than those in the control group (P 0. 05). The total effective rate in the experimental group was significantly higher than that in the control group (P 0. 05) No serious patient complications occurred. Conclusion Mechanical ventilation is effective in treating severe bronchial asthma, which can improve the clinical symptoms of patients with less complications.
