目的探讨无创呼吸机治疗肺结核合并呼吸衰竭的临床疗效。方法选取我院2012年8月—2013年9月收治68例使用无创呼吸机治疗的肺结核合并呼吸衰竭患者作为观察组,同期收治60例应用常规方法治疗的肺结核合并呼吸衰竭患者作为对照组,观察2组患者的临床治疗效果。结果 2组患者治疗后动脉血气分析中pH值、动脉血氧分压(PaO2)、动脉血二氧化碳分压(PaCO2)以及呼吸频率等均较治疗前有所改善,观察组的改善效果更为明显,差异均具有统计学意义(P<0.05);观察组患者病死率为2.9%,明显低于对照组的11.7%,差异具有统计学意义(P<0.05)。结论无创呼吸机治疗肺结核合并呼吸衰竭的临床疗效较好,能显著改善血气指标以及呼吸频率,提高患者生存率,值得临床应用推广。
Objective To investigate the clinical efficacy of noninvasive ventilator in the treatment of pulmonary tuberculosis complicated with respiratory failure. Methods From August 2012 to September 2013, 68 patients with pulmonary tuberculosis complicated with respiratory failure treated with noninvasive ventilator in our hospital were selected as the observation group. Sixty patients with pulmonary tuberculosis complicated with respiratory failure treated by routine method were selected as the control group, 2 groups of patients with clinical treatment. Results In the arterial blood gas analysis after treatment, the pH value, PaO2, PaCO2 and respiratory rate of arterial blood gas analysis in the two groups were all improved after treatment, and the improvement effect of the observation group was more obvious (P <0.05). The mortality of the observation group was 2.9%, which was significantly lower than that of the control group (11.7%), the difference was statistically significant (P <0.05). Conclusion Noninvasive ventilator is effective in treating pulmonary tuberculosis complicated with respiratory failure, and can significantly improve the blood gas index and respiratory rate and improve the survival rate of patients, which is worth popularizing in clinical application.
