Effect of Dexmedetomidine Combined with Ultrasound-guided Brachial Plexus Block on Sleep Quality in Patients Undergoing Upper Limb Frac-ture Surgery
Objective To analyze the effect of dexmedetomidine combined with ultrasound-guided brachial plexus block on sleep quality in patients undergoing upper limb fracture surgery.Methods 103 patients with upper limb frac-ture admitted to Wujin Hospital Affiliated to Jiangsu University from January 2020 to May 2023 were conveniently se-lected as the study objects.The patients were divided into the observation group and the control group by random num-ber table method.There were 52 cases in the observation group and 51 cases in the control group.The control group was given ultrasound guided brachal plexus block anesthesia,and the observation group was combined with dexme-detomidine anesthesia on the basis of the control group.The mean arterial pressure and heart rate immediately after anesthesia(T0),5min after anesthesia(T1),30min during surgery(T2),and immediately after surgery(T3)were observed and compared between the two groups.The Pittsburgh sleep quality index was used to evaluate the sleep quality of the two groups 1 d after surgery.Results Arterial pressure fluctuation of T0 and T3 in observation groups were lower than those in control group,and the differences were statistically significant(all P<0.05).The fluctuation of heart rate of T0,T1 and T3 in observation groups were lower than those in control group,and the differences were statistically signifi-cant(all P<0.05).The sleep quality of observation group(7.63±2.58)points was higher than that of control group(11.28±2.37)points 1 d after surgery,and the differences were statistically significant(t=7.473,P<0.05).Conclusion Dexmedetomidine combined with ultrasound-guided brachial plexus block can improve sleep quality in patients un-dergoing upper limb fracture surgery.And it can maintain the stability of hemodynamic indexes of patients.For pa-tients undergoing surgery for upper limb fractures,which can have a positive impact on the course of treatment for pa-tients undergoing surgery for upper limb fratures.
