无创正压通气在急诊治疗重症支气管哮喘合并呼吸衰竭的临床效果

Clinical efficacy of noninvasive positive pressure ventilation in emergency treatment of severe bronchial asthma with respiratory failure

目的:探讨无创正压通气在急诊治疗重症支气管哮喘合并呼吸衰竭的临床效果。方法:收治重症支气管哮喘合并呼吸衰竭患者60例,分为对照组和研究组。对照组采用常规对症治疗,研究组采用常规对症治疗联合无创正压通气,比较两组治疗效果。结果:治疗后,两组PaO_2、SpO_2和PaCO_2水平均显著改善(P<0.05),且研究组改善程度优于对照组(P<0.05);研究组总有效率高于对照组,住院时间短于对照组(P<0.05);两组并发症差异无统计学意义(P>0.05)。结论:无创正压通气在急诊治疗重症支气管哮喘合并呼吸衰竭的临床效果显著。

Objective:To explore the clinical efficacy of noninvasive positive pressure ventilation in emergency treatment of severe bronchial asthma with respiratory failure.Methods:60 patients with severe bronchial asthma and respiratory failure were selected,they were divided into the control group and the study group.The control group was treated with conventional symptomatic therapy,the study group was treated with conventional symptomatic therapy combined with noninvasive positive pressure ventilation,we compared the therapeutic effects of the two groups.Results:After treatment,the levels of PaO2,SpO2 and PaCO2 in the two groups were significantly improved(P<0.05),and the improvement degree of the study group was better than that of the control group(P<0.05).In the study group,the total effective rate was higher than that in the control group,and the length of stay in the study group was shorter than that in the control group(P<0.05).There was no significant difference in complications between the two groups(P>0.05).Conclusion:The clinical efficacy of noninvasive positive pressure ventilation in emergency treatment of severe bronchial asthma with respiratory failure was significant.
