目的:探讨双水平气道正压通气对左心力衰竭并发急性肺水肿的治疗效果。方法:57例左心力衰竭患者在常规治疗基础上加用无创机械通气,观察分析双水平气道正压通气治疗前、后患者病情和血气分析结果。结果:与无创机械通气治疗前比较,49例患者治疗后病情好转,患者呼吸频率、心率明显减慢,血气分析指标均明显改善,血压和pH恢复正常;血气分析指标(除p(CO2)外)与治疗前比较,差异均有统计学意义(P>0.05)。结论:常规治疗基础上辅助双水平气道正压通气治疗,可明显改善左心力衰竭并发急性肺水肿患者病情及血气分析结果,是治疗急性心源性肺水肿安全、有效的一线治疗手段。
Objective: To investigate the therapeutic effect of bi-level positive airway pressure on acute pulmonary edema in patients with left heart failure. Methods: Fifty-seven patients with left heart failure were treated with noninvasive mechanical ventilation on the basis of routine treatment. The patients’ condition and blood gas analysis results before and after bi-level positive airway pressure were observed and analyzed. Results: Compared with that before noninvasive mechanical ventilation, the symptoms of 49 patients improved after treatment. The respiratory rate and heart rate of patients decreased obviously. The indexes of blood gas analysis were significantly improved and the blood pressure and pH returned to normal. The indexes of blood gas analysis (excluding p (CO2) ) Compared with before treatment, the difference was statistically significant (P> 0.05). Conclusion: Based on the routine therapy, the double-level positive airway pressure therapy can significantly improve the condition and blood gas analysis results of patients with left heart failure complicated by acute pulmonary edema and is a safe and effective first-line treatment for acute cardiogenic pulmonary edema.
