目的探讨无创持续气道正压通气对重型急性左心衰的治疗作用。方法将83例重型急性左心衰患者随机分为两组。A组在内科常规治疗的同时使用无创持续气道正压通气(43例),B组(40例)只使用内科常规治疗。在治疗前和治疗2h后进行两组间动脉血气分析监测指标(Pa02、PaC02、Sa02)对比分析。结果治疗前A组和B组中Pa02、PaC02、Sa02等指标无明显差异;治疗2h后A组的Pa02、PaC02、Sa02等指标较B组有明显差异,P<0.05。结论重型急性左心衰在内科常规治疗的同时加用无创持续气道正压通气能更快更有效的得到纠正。
Objective To investigate the therapeutic effect of non-invasive continuous positive airway pressure on severe acute left heart failure. Methods A total of 83 patients with severe acute left heart failure were randomly divided into two groups. Group A received routine noninvasive continuous positive airway pressure (n = 43) while conventional treatment, while group B (n = 40) received routine medical treatment only. Before treatment and after treatment 2h arterial blood gas analysis between the two groups monitoring indicators (Pa02, PaCO2, Sa02) comparative analysis. Results There were no significant differences in PaO2, PaCO2, SaO2 and other indicators between group A and group B before treatment; PaO2, PaCO2, SaO2 and other indicators in group A were significantly different from those in group B after treatment for 2h (P <0.05). Conclusion Severe acute left heart failure can be corrected more quickly and effectively in the routine medical treatment combined with noninvasive continuous positive airway pressure.
