Abstract: Objective To evaluate ultrasound-guided nerve block combined with general anesthesia in elderly patients with knee arthroplasty application effect. Methods From 2013 January to 2015 December in our hospital underwent knee arthro-plasty 64 cases of elderly patients were divided to 2 groups (32 cases), control group was treated with laryngeal mask inser-tion of Intravenous Inhalation Combined with general anesthesia, combined group by ultrasonic guided nerve block com-bined with general anesthesia. The changes of hemodynamics and postoperative pain were compared between the two groups. Results Respectively, were an additional dose of sufentanil combined group, total intravenous patient-controlled analgesia dose (5±5) μg, (15±5) μg, (66.2±3.8) μg were significantly less than control group (35±10) μg, (50±10) μg, (92.2±5.8) μg, P﹤0.05. The combined group of t2~t4 map value was significantly lower than that of control group, T2, T3 HR values were significantly lower than those of the control group, P﹤ 0.05; the combined group after 2h, 24h, the VAS score (0.6± 0.2) and (2.1±0.7), the control group respectively (2.2±0.6), (4.2±1.1), the group had significant difference (P﹤ 0.05). The inci-dence of postoperative nausea and vomiting in combination group and control group were 12.50% (4/32), 3.13% (1/32), and there were significant differences among groups (P﹤0.05). Conclusion The use of ultrasound-guided nerve block combined with general anesthesia, better able to maintain hemodynamic stability, reduce intraoperative, postoperative pain medication use in the elderly knee replacement surgery, and will not increase the adverse anesthesia the reaction is a safe and effective anesthesia.
