摘　　要：术后苏醒延迟是指全身麻醉停止给药后90分钟,排除脑血管意外,患者仍然意识不清即对指令动作、定向能力和术前记忆没有恢复等。它导致脱机困难,增加患者术后风险。静脉药物的蓄积和残余作用是老年患者术后苏醒延迟的主要原因。呋塞米抑制肾脏对水和钠离子的重吸收,间接加速麻醉药物排泄。呋塞米能预防和减少老年患者术后苏醒延迟的发生。Postoperatively delayed awakening is defined that after the general anesthesia was stopped 90 minutes, patients that were excluded cerebrovascular accident weren＇t still recovered consciousness. Postoperative awakening included demanded movements, directional capabilities, preoperative memory and so on. It will lead to difficultly taking off ventilator and increasing the risk of postoperative.The main reason of senile delayed awakening is that venous anesthetics accumulations and residual acts of venous anesthetics. Furosemide could inhibit the repeating absorption of water and sodium ions and indirectly accelerate the renal clearance of venous narcotics. It could prevent and reduce the occurrence of in elderly patients.postoperative delayed awakening.
