Application effects of Dexmedetomidine in ultrasound-guided multipoint iliac fascia space block anesthesia in total hip arthroplasty of elderly patients with hip fractures
Objective:To observe application effects of Dexmedetomidine in ultrasound-guided multipoint iliac fascia space block anesthesia in total hip arthroplasty of elderly patients with hip fractures.Methods:The clinical data of 76 elderly patients with hip fractures who underwent total hip arthroplasty in this hospital from April 2021 to April 2023 were retrospectively analyzed.They were divided into observation group(n=38)and control group(n=38)according to different anesthesia schemes.Both groups underwent ultrasound-guided multipoint iliac fascia space block anesthesia.The control group was given 0.3%Ropivacaine hydrochloride,while the observation group was given Dexmedetomidine hydrochloride anesthesia on the basis of that of the control group.The perioperative indexes(anesthetic awareness time,extubation time)levels,the pain degree[visual analogue scale(VAS)]before and after the surgery,the hemodynamic indexes[heart rate,mean arterial pressure(MAP)]levels at different time[before anesthesia(T0),10 min after the surgery(T1),end of the surgery(T2)],the incidence of adverse reactions within 1 d after the surgery,and the anesthesia satisfaction were compared between the two groups.Results:There were no significant differences in the anesthetic awareness time and the extubation time between the two groups(P>0.05).6 and 24 h after the surgery,the VAS scores of the observation group were lower than those of the control group,and the differences were statistically significant(P<0.05).At T1 and T2,the heart rate and MAP levels of the two groups were higher than those at T0,but those in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).The anesthesia satisfaction of the observation group was 92.11%(35/38),which was higher than 71.05%(27/38)of the control group,and the difference was statistically significant(P<0.05).Conclusions:Dexmedetomidine combined with ultrasound-guided multipoint iliac fascia space block anesthesia in the elderly patients with hip fractures can reduce the levels of hemodynamic index levels and the VAS scores,and improve the anesthesia satisfaction.Moreover,it is superior to single 0.3%Ropivacaine hydrochloride anesthesia.
