Abstract:
Objective To observe the analgesic effect of ultrasound-guided and nerve stimulator after artificial total knee athroplasty(TKA).Methods Forty elective cases receiving TKA under gen-eral anesthesia were randomly allocated into the ultrasound group (group C)and stimulator group (group S).The time for nerve block,onset time and complications were recorded in both groups. Results Compared to group S,the time for nerve block and onset time was significantly shortened in group C (P <0.05).There was no statistical difference in times of pressing analgesic pump and VAS score in postoperative 48 h.One patient suffered from nerve injury and two underwent vascular dam-age and hematoma in group S,while no complication was found in group C.Conclusion Compared to nerve stimulator,ultrasound-guided continuous femoral nerve block(CFNB)may reduce nerve block time and onset time and decrease complications,so that to increase safety of CFNB.
