Study on the Anesthetic effect of Dexmedetomidine combined with brachial plexus block in elderly patients undergoing upper limb fracture surgery
Objective To investigate the anesthetic effect of dexmedetomidine(Dex)combined with brachial plexus block(BPB)in elderly patients undergoing upper limb fracture surgery.Methods A total of 88 elderly patients with upper limb fracture surgery treated in our hospital from March 2022 to March 2023 were divided into two groups according to the random number table method.The control group(44 patients)received BPB anesthesia,while the observation group(44 patients)received Dex combined with BPB anesthe-sia.Hemodynamics,sedation effect,pain intensity,sensory and motor block duration,comfort level,and ad-verse reactions were recorded and compared between the two groups.Results In the observation group,heart rate(HR)and mean arterial pressure(MAP)at skin incision(T1)and end of surgery(T2)were lower than those 10 minutes before anesthesia(T0),and the Ramsay sedation score was higher than that at T0.In the control group,HR and MAP at T1 were higher than those at T0.Moreover,at T1 and T2,HR and MAP in the observation group were lower than those in the control group,and the Ramsay sedation score was higher in the observation group,with statistically significant differences(P＜0.05).The visual analog scale(VAS)score in the observation group was lower than that in the control group,the sensory block duration was longer in the observation group,and the Bruggemann comfort scale(BCS)score was higher in the observation group,with statistically significant differences(P＜0.05).There were no statistically significant differences in motor block duration and total incidence of adverse reactions between the two groups(P＞0.05).Conclusion Dex combined with BPB is beneficial for stabilizing hemodynamics in elderly patients undergoing upper limb frac-ture surgery,prolonging sensory block duration,providing good sedation and analgesia,improving patient comfort,and ensuring high clinical safety.
