9、 左室增大 left ventricle becomes bigger,诊治经过,12月16日前完善术 前准备,12月17日-19日在ICU治疗,12月20日患 者病情平稳 搬回病房。,Preoperative preparation was completed before December 16th.,The patient was stablly moved back to the ward on December 20th,病 情,12月17日在全麻CPB下行主动脉瓣置换术，术毕于12：50分带气管插管返ICU，呼吸机辅助呼吸，清醒后，查血气示正常，于22：30分拔出气管插管改面罩供氧
10、。血氧饱和度99-100，患者咳嗽咳痰力量稍差 On december 17th, the aortic valve replacement was completed under general anesthesia CPB ,and the patient returned the icu at 12:50 with ventilator breathing. After waking, her blood check showed normal, so pulled out endotracheal intubation and it was replace by oxygen mask
