摘　　要：BACKGROUND Lower extremity fractures are mainly treated by surgical reduction,but this operation is often affected by the patient’s level of agitation and the type of anesthesia used.The main treatment for lower-extremity fractures is operative reduction.However,operations can often be affected by both agitation and the degree of anesthesia.Therefore,it is of great importance to develop an effective anesthesia program to effectively ensure the progress of surgery.AIM To discuss the effect of ultrasound-guided nerve block combined with dexmedetomidine anesthesia in lower extremity fracture surgery.METHODS A total of 120 hospital patients with lower extremity fractures were selected for this retrospective study and divided into an observation group(n=60)and a control group(n=60)according to the anesthesia scheme;the control group received ultrasound-guided nerve block;the observation group was treated with dextromethomidine on the basis of the control group,and the mean arterial pressure,heart rate(HR),and blood oxygen saturation were observed in the two groups.RESULTS The mean arterial pressure of T1,T2 and T3 in the observation group were 94.40±7.10,90.84±7.21 and 91.03±6.84 mmHg,significantly higher than that of the control group(P<0.05).The observation group’s HR at T1 was 76.60±7.52 times/min,significantly lower than that of the control group(P<0.05);The observation group’s HR at T2 and T3 was 75.40±8.03 times/min and 76.64±7.11 times/min,significantly higher than that of the control group(P<0.05).The observation group’s visual analog score at 2 h,6 h and 12 h after operation was 3.55±0.87,2.84±0.65 and 2.05±0.40.the recovery time was 15.51±4.21 min,significantly lower than that of the control group(P<0.05).Six hours post-anesthesia,epinephrine and norepinephrine in the observation group were 81.10±21.19 pg/mL and 510.20±98.27 pg/mL,significantly lower than that of the control group(P<0.05),and the mini-mental state exam score of the observation group was 25.51±1.15,significantly higher th
