目的观察常规治疗联合无创双水平气道正压通气(bi-level positive airway pressure ventilation,BiPAP)治疗急性左心衰竭的临床效果。方法 32例急性左心衰竭患者均在常规药物治疗基础上给予BiPAP辅助治疗,观察BiPAP治疗前、后患者心率、血压、脉搏血氧饱和度、临床症状及体征等指标的变化。结果 BiPAP辅助治疗24h,显效9例、有效18例、无效5例,总有效率84.4%;均未发生气胸、纵隔气肿等并发症;BiPAP辅助治疗后12,24h患者脉搏血氧饱和度较治疗前增高(P<0.01),收缩压、舒张压、心率较治疗前降低(P<0.05)。结论常规药物治疗基础上给予BiPAP辅助治疗急性左心衰竭疗效满意。
Objective To observe the clinical effects of conventional therapy combined with bi-level positive airway pressure ventilation (BiPAP) in the treatment of acute left heart failure. Methods 32 patients with acute left heart failure were given BiPAP adjuvant therapy on the basis of routine drug therapy. The changes of heart rate, blood pressure, pulse oximetry, clinical symptoms and signs before and after BiPAP treatment were observed. Results BiPAP adjuvant therapy for 24h, markedly effective in 9 cases, effective in 18 cases, ineffective in 5 cases, the total effective rate was 84.4%; no pneumothorax, mediastinal emphysema and other complications; BiPAP adjuvant therapy 12,24 h after patients with pulse oximetry Before treatment (P <0.01), systolic blood pressure, diastolic blood pressure and heart rate were lower than those before treatment (P <0.05). Conclusion The conventional pharmacotherapy based on BiPAP adjuvant treatment of acute left heart failure with satisfactory results.
