Analysis of Anesthesia Effect of Femoral Nerve+Sciatic Nerve Block Under Ultrasound Guidance in Elderly Patients Undergoing Femoral Head Replacement Surgery
Objective To analyze the analgesic effect of femoral nerve+sciatic nerve block guided by ultrasound on elderly patients undergoing femoral head replacement surgery. Methods A total of 102 elderly patients who underwent femoral head replacement surgery from October 2021 to October 2023 were selected and divided into a study group (n=51) and a control group (n=51) by the random number method. The control group received combined epidural anesthesia,and the study group received femoral nerve+sciatic nerve block under ultrasound guidance. Anesthesia block time,postoperative analgesia time,postoperative recovery time,first ambulation time,postoperative delirium,adverse reactions,heart rate (HR),mean arterial pressure (MAP),and Visual Analogue Scale (VAS) score at different time points were observed and recorded for the two groups. Results TThe anesthesia block time and postoperative analgesia time were longer in the study group compared with the control group (P<0.05),and the postoperative awakening time and first ambulation time were shorter compared with the control group (P<0.05). The incidence of delirium during the postoperative awakening period in the study group was 7.84%,which was lower than the 29.41% in the control group (P<0.05). Compared with before anesthesia,HR and MAP were increased at 30 min and 60 min after anesthesia in both groups. The increase in MAP in the study group was lower than in the control group,and the increase in HR was higher than in the control group (P<0.05). The VAS scores at 6 h,24 h,and 48 h post-surgery in the study group were (3.18±0.32) points,(3.60±0.56) points,and (1.33±0.21) points,which were lower than those in the control group at 6 h,24 h,and 48 h after surgery (4.36±0.41) points,(5.88±0.85) points,and (2.01±0.28) points (P<0.05). The rate of adverse reactions in the study group (5.88%) was lower than in the control group (25.49%)(P<0.05). Conclusion Ultrasound-guided femoral nerve+sciatic nerve block demonstrated excellent efficacy for elderly patients undergoing femoral head replacement surgery. It not only prolonged the anesthesia block time and shortened the postoperative awakening time and first ambulation time but also stabilized the intraoperative vital signs,improved the postoperative analgesia effect,and effectively reduced the occurrence of postoperative delirium during the awakening period. It was safe and worthy of clinical application and promotion.
