无创双水平气道正压通气治疗急性心源性肺水肿临床观察

目的:研究无创双水平气道正压通气对急性心源性肺水肿的治疗效果。方法:选择20例经常规方法治疗无效的急性心源性肺水肿患者进行BiPAP,记录临床症状、体征、彩色多普勒二维超声心动图、血气分析等指标监测。结果:20例急性心源性肺水肿患者抢救成功18例次,抢救成功率90%。治疗2h后生命体征稳定、心衰减轻,PaO2明显提高(P<0.01)。3d后心脏射血分数明显增加(P<0.01)。结论:BiPAP通过调节适当压力水平,可改善心功能,减轻肺水肿,迅速提高血氧含量。

The Treatment of Acute Cardiogenic Pulmonary Edema with Noninvasive Bi - level Positive Airway Pressure Ventilation

Objective: To evaluate the effects of noninvasive bi-level positive airway pressure ventilation.Methods: 20 patients with acute cardiogenic pulmonary edema was treated with noninvasive bi-level positive airway pressure ventilation.Clinical symptoms,signs,two-dimersional color Doppler echocardiogram and blood gas analysis were monitored.Results: 18 patients survived with a success rate of 90%.Significant improvements of vital signs,PaO_2 was found(P<0.01)4 hours after ventilation.Ejection fraction was improved markedly(P<0.01)3 days after ventilation.Conclusion:Noninvasive bi-level positive airway pressure ventilation can decrease the pulmonary edema,elevate PaO_2 and promptly improve heart function.
