摘要
目的：观察髋关节置换术中骨水泥对血流动力学的影响。方法：20例ASAⅠ-Ⅱ均采用连续硬膜外麻醉,麻醉平面控制在T10-T11,术前静脉输入林格氏液扩容,术中监测Bp、ECG、SPO2、HR,记录置入骨水泥不同时间的BP、HR。结果：应用骨水泥后血压下降、心率增快（P〈0.05）,但未出现呼吸循环系统的严重并发症。结论：骨水泥可使血管扩张抑制心肌而引起血流动力学的改变。
Objective： To investigate the effects of insertion of acrylic cement into medullary cavity of the femur on hemodynamics during hip arthroplasty. Methods： Twenty patients, ASA Ⅰ - Ⅱ, received continuous epidural anesthesia. Compound sodium chloride injection was injected. Blood pressure （SBP, DBP）, heart rate （HR） were recorded in different time points. Results： SBP and DBP decreased and HR increased significantely immediately following insertion of acrylic cement （P 〈 0.05）. Conclusion： While acrylic cement may dilate blood vessel transiently and inhibit mycardial contractile function much longer.
