Abstract:
Objective To observe the clinical effect of dexmedetomidine for preventing agitation during extubation period in the patients undergoing percutaneous nephrostolithotomy.Methods Sixty ASA Ⅰ-Ⅱ patients with elective percutaneous nephrostolithotomy under general anesthesia were selected and randomly assigned to the dexmedetomidine (DEM) and normal saline group (NS),30 cases in each group.The DEM group was given dexmedetomidine 0.5 μg/kg by intravenous pumping at 30 min before the end of the operation,while the NS group was given the equal volume of normal saline by intravenous pumping for 10 min.MAP and HR were recorded before anesthesia induction(T0),at the end of skin suturing(T1),at the moment of extubation(T2),at 5 min (T3) and 10 min(T4)after extubation.The eye opening time and extubation time,and incidence of agitation were observed in the two groups.Results MAP and HR at T2,T3 and T4 in the DEM group were lower than those in the NS group(P＜0.05).MAP and HR at T2,T3,T4 in the NS group were higher than those before anesthesia induction(P＜0.05).The total incidence rate of agitation during extubation period in the DEM group was also significantly lower that that in the NS group(P＜0.01).No statistically significant differences were found between the two groups in the recovery time and extubation time(P＞0.05).Conclusion Intravenous pumping of dexmedetomidine 0.5 μg/kg at 30 min before the end of percutaneous nephrostolithotomy can effectively reduce the occurrence of agitation during extubation period.
