摘　　要：目的:探讨超声引导下右美托咪定复合罗哌卡因股神经阻滞对膝关节镜联合胫骨高位截骨术(HTO)后患者疼痛的影响。方法:选择2021-2022年在安康市中心医院行HTO联合关节镜治疗的97例骨性关节炎患者,依据随机数表法将其分为观察组(46例)和对照组(51例),所有患者均予以超声引导下股神经阻滞麻醉,观察组使用罗哌卡因复合右美托咪定,对照组仅使用罗哌卡因。评估患者术前,术后3、6和12 h时静息状态下的疼痛视觉模拟量表(VAS)评分,记录患者术后0~6 h(T1)、6~12 h(T2)、12~18 h(T3)及18~24 h(T4)4个时间段内按压静脉自控镇痛(PCA)按钮的次数,以及术后24、48和72 h内口服阿片类药物剂量,并记录术后麻醉相关的不良反应。结果:观察组术后3、6和12 h时疼痛水平均明显较对照组更低,其差异有统计学意义(t=2.181、3.113、3.073,P<0.05);观察组患者术后24、48和72 h内阿片类药物服用剂量显著少于对照组,差异有统计学意义(t=6.356、9.778、11.284,P<0.05),术后T1、T2时间段内按压PCA按钮的次数也显著低于对照组,差异有统计学意义(t=5.033、2.184,P<0.05);观察组不良反应发生率较对照组更低,差异有统计学意义(x^(2)=4.562,P<0.05)。结论:在膝关节镜联合HTO手术麻醉中应用右美托咪定复合罗哌卡因股神经阻滞早期镇痛效果显著,患者术后阿片类药物口服量降低,且其术后麻醉相关不良反应的发生风险较小。Objective:To explore the effect of ultrasound-guided femoral nerve block with dexmedetomidine combined with ropivacaine on the pain of patients after knee arthroscopy combined with high tibial osteotomy(HTO).Methods:A total of 97 patients who underwent the treatment of HTO combined with knee arthroscopy in the Ankang central hospital from 2021 to 2022 were selected,and they were divided into the observation group(46 cases)and the control group(51 cases)based on the random number table method.All patients received anesthesiology with ultrasoundguided femoral nerve block.For anesthesia,the observation group used ropivacaine combined with dexmedetomidine,and the control group only used ropivacaine.The visual analogue scale(VAS)scores of them were assessed respectively at rests before surgery,and 3h,6h and 12h after surgery,and the times that patients pressed the button of patient controlled analgesia(PCA)within 4 time intervals included the postoperative 0-6h(T1),6-12h(T2),12-18h(T3)and 18-24 h(T4)were recorded.In addition,the doses of oral opioid drug within postoperative 24 h,48 h and 72 h also were recorded,and the relevant adverse reactions of anesthesiology after surgery were recorded.Results:The pain levels at postoperative 3h,6h and 12h in the observation group were significantly lower than those in the control group,and the differences were statistically significant(t=2.181,3.113,3.073,P<0.05),respectively.The oral dosage of opioids within 24h,48h and 72h after surgery in observation group were significantly less than those in the control group,and the differences were statistically significant(t=6.356,9.778,11.284,P<0.05),respectively.The times of pressing PCA button within T1 and T2 intervals after surgery in observation group were also significantly lower than those in control group,and the differences were statistically significant(t=5.033,2.184,P<0.05),respectively.The incidence of adverse reactions in the observation group was significantly lower than that in the control group,and the difference was st
