夜间患者处于睡眠状态,由于卧位时回心血量增加,肺充血加重;另一方面,易引起冠状动脉痉挛,致心肌供氧量减少,故夜间急性左心衰竭的发生率高,病死率也相当高。由于夜间工作人员少,患者都在睡眠过程中,给观察带来了一定的困难。在单独的夜班工作中,先后发现6例急性左心衰竭的患者,发病年龄50～70岁,发病时间多在夜间1时至次晨5时,现将对其早期判断及处理体会总结如下。早期征兆判断
Nighttime patients in the sleep state, due to lying back when the amount of blood back to the heart, increased pulmonary congestion; the other hand, can easily lead to coronary spasm, decreased myocardial oxygen supply, so the incidence of acute left heart failure at night, the mortality rate is also Very high. Due to the small staff at night, patients are in the process of sleep, to bring some difficulties to the observation. In a separate night shift work, we found six patients with acute left heart failure, the onset age of 50 to 70 years old, onset time and more in the evening 1:00 to 5:00, now its early judgment and treatment experience is summarized as follows. Early signs to judge
