无创呼吸机在心力衰竭治疗中的应用

目的探讨无创呼吸机（BiPAP）在救治急性左心力衰竭中的应用价值。方法60例急性左心力衰竭患者随机分为治疗组与对照组各30例，治疗组在常规抗心力衰竭治疗基础上联用呼吸机面罩正压通气治疗，对照组为常规抗心力衰竭治疗，测定治疗前后动脉血pH、PaO2、PaCO2，观察血压、心率、呼吸及临床症状，并进行分析。结果治疗组治疗后pH、PaO2、PaCO2、心率、呼吸、血压均较明显改善（P〈0．05），治疗显效率46．67％（14例），明显高于对照组30．00％（9例）（P〈0．05）；治疗组总有效率93．33％（28例），对照组总有效率73．33％（22例），治疗组有效率较对照组明显增高（P〈0．05）。结论无创呼吸机对急性左心力衰竭的治疗有一定效果。

Treatment of acute heart failure with conventional ltherapy and bi-level positive airway pressure

Objective To evaluate the therapeutic effects of bi-level positive airway pressure on acute left heart failure. Methods Thirty patients with acute left heart failure received combined conventional therapy and bilevel positive airway pressure, and were compared with 30 patients with acute left heart failure receiving traditional treatment as controls. The changes in the power of hydrogen, partial pressure of oxygen in artery, pulse oxygen saturation,partial pressure of carbondioxide in artery,buffuer excess,blood pressure,heart rate,and breathing frequency,and clinical symptom were compared between the two groups. Results Compared with control group,the blood pressure,heart rate, breathing frequency decreased significantly( P＜0. 05 ) ;pulse oxygen saturation increased significantly (P＜0. 05 ) ; the power of hydrogen, partial pressure of oxygen in artery, partial pressure of carbondioxide in artery, and buffuer excess were improved more significantly ( P＜0. 05 ) ; the marked response rate and the total effective rate increased significantly(P＜0. 05). Conclusion The combined conventional therapy and bi-level positive airway pressure has a good efficacy in the patients with acute left heart failure.
