Clinical observation of dexmedetomidine given intranasally for day surgery recovery period / 中国基层医药

ABSTRACT

Objective To evaluate the clinical efficacy of dexmedetomidine given intranasally for day surgery recovery period.Methods 60 pediatric patients who were treated for elective day surgery were selected as study objects,and they were randomly divided into control group and observation group according to the digital table,30 cases in each group.During operation, after induction of 8% sevoflurane inhalation at 8 L/min,3% of sevoflurane was maintained at 1 L/min.After intubation,0.5 g dexmedetomidine was given intranasally in the observation group, 0.9% NaCl saline was given to the control group.Mean arterial pressure (MAP),heart rate (HR),oxygen saturation (SpO2) were observed at different time points.The recovery time, number of cases of agitation, Aono agitation scale, children anesthesia delirium PAED score and the incidence of adverse reactions were observed in the two groups.Results As the time passed by, the MAP,HR,SpO2 in the two groups stabilized, except HR of the observation group at T0 time was higher than the control group[(92.92±3.22)beats/min vs.(89.32±3.22) beats/min], the difference was statistically significant(t=2.34,P0.05).The overall incidence of adverse reactions was similar in the two groups, there was no statistically significant difference (13.33% vs.10.00%,x2=0.12,P>0.05).Conclusion Dexmedetomidine given intranasally for the children underwent day surgery can significantly improve the quality of children awakeness, reduce the incidence of postoperative delirium, and without significant side effects.
