目的观察双水平正压(bilevel positive airway pressure,BiPAP)通气治疗急性心源性肺水肿的临床疗效。方法将临床明确诊断的急性心源性肺水肿患者随机分成BiPAP通气治疗组和常规治疗组,进而比较两组的治疗效果。结果与常规治疗组比较,BiPAP组的呼吸频率(RR)、心率(HR)、血压(SBP)、呼吸困难缓解程度、肺部体征和血气分析指标明显改善(P<0.05),总有效率73.08%。结论双水平正压通气治疗急性左心衰能改善氧合、动脉血氧分压及呼吸困难,减少气管插管或气管切开,提高抢救成功率。
Objective To observe the clinical efficacy of bilevel positive airway pressure (BiPAP) ventilation in the treatment of acute cardiogenic pulmonary edema. Methods Patients with acute cardiogenic pulmonary edema diagnosed clinically were randomly divided into BiPAP ventilation group and conventional treatment group, and then the treatment effect was compared between the two groups. Results Compared with the conventional treatment group, the respiratory rate (RR), heart rate (HR), blood pressure (SBP), degree of relief of dyspnea, pulmonary signs and blood gas analysis indexes in BiPAP group were significantly improved (P <0.05) %. Conclusions Biphasic positive pressure ventilation can improve oxygenation, arterial oxygen tension and dyspnea in acute left heart failure, decrease tracheal intubation or tracheotomy, and improve the success rate of rescue.
