A 70-year-old man underwent total hip replacement surgery under general anesthesia, endotracheal intubation, and controlled ventilation, with the patient in left lateral position. Intraoperatively, the patient was hemodynamically stable, with a normal range of pulse, ECG trace, oxygen saturation as measured by pulse oximetry (Spo2), and end-tidal CO2 (etco2). Five minutes after insertion of the hip prosthesis, his heart rate dropped to 30 beats/min, BP to 40/30 mm Hg, Spo2 to 70%, and etco2 to 10 mm Hg.
一位 70 岁男性在全身麻醉、气管插管和控制通气下接受了全髋关节置换手术，患者处于左侧卧位。术中患者血流动力学稳定，脉搏、心电图轨迹、脉搏血氧饱和度（SpO2）和呼气末二氧化碳（etCO2）均在正常范围内。在插入髋关节假体后 5 分钟，他的心率降至 30 次/分，血压降至 40/30 mmHg，SpO2 降至 70%，etCO2 降至 10 mmHg。
