目的:观察无创正压通气(NPPV)治疗充血性心力衰竭(CHF)的临床疗效:方法:90例CHF患者随机分为治疗组(60例)和对照组(30例),对照组采用常规CHF治疗,治疗组在对照组治疗基础上,给予NPPV治疗,记录治疗前、后患者的左室射血分数(LVEF),每分钟输出量(CO),每搏输出量(SV)并比较。结果:CHF患者的LVEF、CO、SV较健康组明显降低,应用NPPV治疗4d后,患者的LVEF、CO、SV较治疗前有明显增加,差异有显著性意义(P<0.05)。结论:采用NPPV可改善CHF患者的左心功能,提高临床疗效。
Objective: To observe the clinical efficacy of noninvasive positive pressure ventilation (NPPV) in the treatment of congestive heart failure (CHF). Methods: 90 CHF patients were randomly divided into treatment group (60 cases) and control group (30 cases) The patients in the treatment group and the control group were treated with NPPV. The left ventricular ejection fraction (LVEF), output per minute (CO) and stroke volume (SV) were recorded and compared before and after treatment. Results: LVEF, CO and SV in CHF patients were significantly lower than those in healthy subjects. After 4 days of NPPV treatment, LVEF, CO and SV in patients with CHF were significantly higher than those before treatment (P <0.05). Conclusion: NPPV can improve left ventricular function in CHF patients and improve clinical efficacy.
