  • 无创正压通气治疗冠状动脉搭桥术后急性左心衰竭的疗效观察

    【摘要】 目的 观察早期无创正压通气对冠状动脉搭桥术后急性左心衰竭所致严重低氧血症的治疗效果。方法 40 例冠状动脉搭桥术后发生急性左心衰竭的患者随机分为两组。对照组( n =20) : 予以面罩吸氧、强心、利尿、扩血管等治疗; 治疗组( n = 20) : 在对照组基础上予以无创面罩正压通气。测定动脉血pH、PaO2、SaO2、PaCO2 , 观察血压、心率、呼吸及临床症状, 并进行相关分析。结果 治疗组在治疗后30 min 开始改善, 在1、3、6 h 时的改善明显优于对照组, 表现在pH、PaO2、PaCO2 、心率、呼吸频率、SaO2 方面( P lt;0. 05) ; 在纠正低PaO2 方面, 治疗组早期即表现出优越性。治疗组急性左心衰竭开始缓解的时间较对照组明显缩短( P lt;0. 01) 。结论 对于冠状动脉搭桥术后急性左心衰竭的冠心病患者, 在抗心衰治疗的同时短期使用无创正压通气可以较快纠正机体缺氧状况, 改善心功能, 缩短急性左心衰竭病程。

  • Research on the Sedative Effects of Midazolam Combined with Morphine during Ventilation Treatment for Patients with Acute Severe Left Ventricular Failure

    目的 评价重症急性左心衰竭患者机械通气时采用咪达唑仑与吗啡联合持续镇静的效果。 方法 选择2007年4月-2010年4月在重症医学科(ICU)进行有创机械通气的重症急性左心衰竭患者86例,随机均分为咪达唑仑组(A组)、咪达唑仑联合吗啡组(B组)。采用Ramsay镇静评分,使每例患者镇静水平达RamsayⅢ~Ⅳ级。观察起效时间、镇静时间、停药后苏醒时间和停药后拔管时间;监测镇静12 h后的血气分析及血流动力学参数的变化。 结果 B组起效时间、镇静时间、停药后苏醒时间和停药后拔管时间明显短于A组(P<0.05)。且镇静12 h后B组血气分析及血流动力学较A组明显改善(P<0.05)。 结论 重症急性左心衰竭患者机械通气时使用咪达唑仑联合吗啡镇静能达到满意镇静效果,同时改善重症急性左心衰竭患者的低氧血症和高碳酸血症。

  • Application of Noninvasive Positive Pressure Ventilation in Patients with Acute Left Heart Failure

    Objective To investigate the effects of noninvasive positive pressure ventilation (NPPV) on patients with acute left heart failure. Methods Twenty patients with acute left heart failure diagnosed between September 2013 and July 2014 were randomized into treatment group (n=10) and control group (n=10). Both groups used conventional sedations, diuretics and drugs that strengthened the heart and dilated the vessels, while early use of NPPV was applied in the experimental group. Arterial blood gas analysis [pH value, pressure of arterial carbon dioxide (PaCO2), and pressure of arterial oxygen (PaO2)], heart rate (HR), respiration, duration of Intensive Care Unit (ICU) stay and invasive mechanical ventilation, duration of overall mechanical ventilation, and success case numbers before and two hours after treatment were observed and analyzed. Results For the control group, two hours after treatment, PaO2 was (67.0±8.5) mm Hg (1 mm Hg=0.133 kPa), HR was (124±10) times/min, Respiration was (34±4) times/min, the duration of ICU stay was (6.0±1.1) days, invasive ventilation was for (32.0±3.1) hours, and the total time of mechanical ventilation was (32.0±3.1) hours. Those indexes for the treatment group two hours after treatment were: PaO2, (82.3±8.9) mm Hg; HR, (98±11) times/min; respiration, (24±4) times/min; the duration of ICU stay, (4.0±0.8) days; invasive ventilation time, (16.0±1.3) hours; the total time of mechanical ventilation, (26.0±1.8) hours. All the differences for each index between the two groups were statistically significant (P < 0.05). Conclusion Early application of NPPV can rapidly relieve clinical symptoms and reduce the medical cost for patients with acute left heart failure.
