目的观察研究中西医结合对改善肺心病呼吸衰竭患者通气功能的疗效。方法选择我院收治的68例肺心病呼吸衰竭患者作为研究对象,随机分为两组,对照组采取常规西医治疗,实验组在对照组基础上辅以自拟中药汤剂口服.比较两组疗效。结果两组咳嗽、咳痰、喘息、胸闷的主症积分在治疗14的后均有明显改善,但治疗组的改善优于对照组.两组FEV1、FVC指标较治疗前均有增加.但治疗组增加幅度更大.差异显著(P<0.05);结论中西医结合疗法能有效改善肺心病伴随呼吸衰竭患者的肺部通气功能.比单纯西医治疗效果好.值得推广。 Objective To observe the curative effect of combining traditional Chinese and western medicine on improving ventilatory function in patients with respiratory failure of pulmonary heart disease. Methods Sixty-eight patients with pulmonary heart disease and respiratory failure were selected and randomly divided into two groups. The control group was treated with routine western medicine. The experimental group was supplemented with self-made Chinese medicine decoction on the basis of the control group. . Results The main symptom scores of cough, expectoration, wheezing and chest tightness in both groups were significantly improved after treatment14, but the improvements in the treatment group were better than those in the control group.The FEV1 and FVC indexes in both groups were increased (P <0.05) .Conclusion The combination therapy of traditional Chinese and western medicine can effectively improve pulmonary ventilation in patients with pulmonary heart disease accompanied by respiratory failure, which is more effective than Western medicine alone and worth promoting.
