目的评价BiPAP面罩式双水平正压通气急性心源性肺水肿病例的疗效。方法用对照分析的方法将63例患者急性心源性肺水肿随机分为两组。治疗组33例急性心源性肺水肿患者在传统常规治疗同时加用BiPAP呼吸机经鼻(面)罩双水平气道正压通气治疗,对照组30例在传统常规治疗上加用鼻导管给氧治疗。结果 BiPAP组患者临床症状、体征明显改善,心率、血压与治疗前比较明显降低,SaO2与治疗前比较明显降低(P<0.05),总有效率为93.9%,避免了气管插管机械通气。对照组总有效率为80%。结论 BiPAP面罩式双水平正压通气治疗急性心源性肺水肿能更迅速纠正缺氧、更显著改善心功能。可作为抢救急性心源性肺水肿的一种安全、快速、有效的方法之一。
Objective To evaluate the efficacy of BiPAP mask in patients with acute cardiogenic pulmonary edema under bi-level positive pressure ventilation. Methods 63 patients with acute cardiogenic pulmonary edema were randomly divided into two groups by the method of comparative analysis. In the treatment group, 33 patients with acute cardiogenic pulmonary edema were treated with BiPAP ventilator nasal (face) mask bi-level positive airway pressure ventilation in the traditional routine treatment. In the control group, 30 patients were treated with nasal catheter Oxygen therapy. Results The clinical symptoms and signs of patients in BiPAP group were significantly improved. Heart rate and blood pressure were significantly lower than those before treatment. SaO2 was significantly lower than that before treatment (P <0.05), and the total effective rate was 93.9%. Mechanical ventilation of tracheal intubation was avoided. The total effective rate of the control group was 80%. Conclusion BiPAP mask bi-level positive pressure ventilation for acute cardiogenic pulmonary edema can more quickly correct hypoxia, but also significantly improve cardiac function. It can be used as a safe, rapid and effective method to rescue acute cardiogenic pulmonary edema.
