Application of ultrasound-guided regional nerve block combined with dexmedetomidine for postoperative analgesia in elderly patients undergoing total hip arthroplasty
Objective To explore the application of ultrasound-guided regional nerve block combined with dexmedetomidine for postoperative analgesia in elderly patients undergoing total hip arthroplasty.Methods A total of 90 patients with total hip arthroplasty admitted to Jinhua People's Hospital from June 2020 to June 2022 were selected.The patients were divided into the observation group and the control group according to random number table,with 45 cases in each group.Both groups were treated with ultrasound-guided regional nerve block,while the observation group was given a combination of dexmedetomidine.The pain scores and sedation scores were compared between the two groups at 6 h,12 h and 24 h postoperatively.The follow-up medication use,complication rates,intraoperative monitoring indices at 30 minutes post-medication,and the incidence of intraoperative adverse events were compared between two groups.Results The pain scores at 6 h,12 h and 24 h after total hip arthroplasty in the observation group were significantly lower than those in the control group,and the sedation scores in the observation group were significantly higher than those in the control group(P＜0.05).The follow-up additional dose and the number of additional uses of the analgesic pump in the observation group were lower than those in the control group(P＜0.05).The incidence of complications in the observation group(2％)was significantly lower than that in the control group(20％)(P＜0.05).There was no statistically significant difference in the intraoperative detection indicators or the incidence of intraoperative adverse events between two groups(P＞0.05).Conclusion The combination of ultrasound-guided regional nerve block combined with dexmedetomidine in elderly patients undergoing total hip arthroplasty can effectively carry out postoperative analgesia,reduce additional medication and improve the occurrence of complications,while exerting minimal adverse effect on the patients during operation.
