目的分析应用无创正压通气治疗肺源性心脏病(肺心病)呼吸衰竭的临床效果。方法 68例肺心病呼吸衰竭患者为研究对象,随机分成观察组和对照组,各34例。对照组给予常规疗法,观察组在常规疗法基础上给予无创正压通气治疗。比较两组患者的治疗效果。结果观察组总有效率94.12%高于对照组76.47%,差异具有统计学意义(P<0.05)。治疗前,两组动脉血二氧化碳分压(PaCO_2)、动脉血氧分压(PaO_2)比较,差异均无统计学意义(P>0.05);治疗后,两组PaCO_2、PaO_2均较本组治疗前改善,且观察组改善程度优于对照组,差异均具有统计学意义(P<0.05)。结论无创正压通气是治疗肺心病呼吸衰竭的辅助措施,其具有操作简单、无创性、疗效显著等特点,能有效缓解患者呼吸困难症状,改善患者血气分析指标,提高临床疗效,值得推广应用。
Objective To analyze the clinical effect of noninvasive positive pressure ventilation in the treatment of pulmonary heart disease (pulmonary heart disease) respiratory failure. Methods A total of 68 patients with pulmonary heart disease and respiratory failure were randomly divided into observation group and control group, with 34 cases in each group. The control group was given conventional therapy. The observation group was given noninvasive positive pressure ventilation on the basis of conventional therapy. The treatment effect of two groups of patients was compared. Results The total effective rate in observation group was 94.12% higher than that in control group (76.47%), the difference was statistically significant (P <0.05). Before treatment, there was no significant difference in PaCO_2 and PaO_2 between the two groups (P> 0.05). After treatment, PaCO_2 and PaO_2 in both groups were significantly lower than those before treatment Improve, and the observation group improved better than the control group, the difference was statistically significant (P <0.05). Conclusion Noninvasive positive pressure ventilation is an auxiliary measure for the treatment of respiratory failure of pulmonary heart disease. It has the characteristics of simple operation, noninvasiveness and significant curative effect. It can effectively relieve the symptoms of dyspnea, improve the blood gas analysis indexes and improve the clinical curative effect. It is worth popularizing and applying.
