心源性肺水肿可因肺有效气体交换面积减少而降低肺顺应性,那么应用强心药治疗能否改善心衰病人的肺顺应性呢?作者选择了因严重心源性肺水肿需行机械通气的呼衰病人20名进行研究。在病人临床情况尚好,无心律失常及心肌缺血征象的情况下,静脉缓慢注射氨力农1mg/kg(10min内注完),随后以10μg·kg~(-1)· Cardiogenic pulmonary edema due to lung effective gas exchange area decreases and reduce lung compliance, then the application of cardiotonic drugs can improve heart failure in patients with lung compliance? The author chose due to severe cardiogenic pulmonary edema required mechanical Ventilation of respiratory failure in 20 patients were studied. In the patient’s clinical situation is good, no arrhythmia and signs of myocardial ischemia, intravenous injection of amrinone slowly 1mg / kg (10min note), followed by 10μg · kg ~ (-1) ·
