Effects of ultrasound-guided ropivacaine combined with dexmedetomidine for brachial plexus block on intraoperative anesthesia effect and hemodynamics in patients with humeral fractures
Objective:To explore the effects of ultrasound-guided ropivacaine combined with dexmedetomidine(DEX)for brachial plexus block(BPB)on intraoperative anesthesia effect and hemodynamics in patients with humeral fractures.Methods:A total of 62 patients with humeral fractures who were treated in our hospital from January 2022 to January 2024 were randomly divided into a control group and an experimental group(n=31).The two groups of patients were treated with ultrasound-guided brachial plexus nerve block using ropivacaine or ropivacaine combined with DEX.The anesthesia block condition(onset and duration of anesthesia block)was compared between the two groups of patients.Non-invasive portable blood pressure monitors were used to measure hemodynamics(heart rate,mean arterial pressure)at different times,and visual analogue scales(VAS)were used to assess the patient's comfort level.The pain scores at different times were measured,and the side effects of anesthesia were recorded and observed.Results:Compared with the control group,the onset and duration of anesthesia block in the experimental group were better(P<0.05).Compared with the control group,the heart rate of the experimental group was higher at T2,T3,and T4(P<0.05).Compared with the control group,the mean arterial pressure at T2,T3,and T4 was lower in the experimental group(P<0.05).Compared with the control group,the VAS scores of the experimental group were lower at 8,12,24,and 48 hours after surgery(P<0.05).During the perioperative period,there was no significant difference in the incidence of side effects between the two groups(P>0.05).Conclusion:The application of ultrasound-guided ropivacaine combined with DEX in BPB can improve the anesthetic effect of patients,improve hemodynamics,reduce postoperative pain,and has good safety.
