目的观察无创双水平气道正压通气(BiPAP)在治疗急性左心衰竭中的应用价值。方法将60例急性左心衰竭患者随机分为2组,每组30例,对照组常规抗心力衰竭治疗,BiPAP组常规抗心力衰竭同时加用BiPAP治疗。分别观察记录2组患者的临床表现及治疗前后心率、呼吸频率和血压的变化。结果BiPAP组有效率为93.3%,对照组有效率为67.9%,2组有效率比较差异有统计学意义(P<0.05)。2组治疗后RR、HR、SpO2均较治疗前改善,治疗组改善明显。结论无创性BiPAP是治疗急性左心衰竭快速、有效的辅助方法之一。
Objective To observe the value of noninvasive bi-level positive airway pressure (BiPAP) in the treatment of acute left heart failure. Methods Sixty patients with acute left heart failure were randomly divided into two groups (n = 30 in each group). The patients in the control group were treated with conventional anti-heart failure and the patients in the BiPAP group were given conventional anti-heart failure combined with BiPAP. The clinical manifestations and the changes of heart rate, respiratory rate and blood pressure before and after treatment were observed and recorded respectively. Results The effective rate was 93.3% in the BiPAP group and 67.9% in the control group. There was significant difference in the effective rate between the two groups (P <0.05). After treatment, RR, HR and SpO2 in both groups improved compared with those before treatment, and the treatment group improved obviously. Conclusion Noninvasive BiPAP is one of the fast and effective auxiliary methods for the treatment of acute left heart failure.
