Abstract:
Objective To investigate the effects of dexmedetomidine on tonsillectomy in children with sevoflurane combined with anesthesia recovery period of restless.Methods A total of 62 patients with tonsillectomy under general anesthesia from 2011 to 2015 in our hospital werecollected and randomly divided into the control group and the experiment group with 31 cases in each.Two groups of children were treated by 7％sevoflurane inhalation anesthesia induction,supplemented by a small amount of intravenous anesthetics propofol 2 mg/kg,sufentanil 2 μg/kg,CIS atracurium 150 μg/kg intravenous injection.Patients in the experiment group were treated by dexmedetomidine 0.2 μg/(kg·h)continuous intravenous infusion until the end of the operation,patients in the control group were treated by normal saline intravenous infusion.Compared the systolic blood pressure and heart rate of the 2 groups of before anesthesia induction,after anesthesia induction,after operation 5min,the end of the operation ; occurred rate of restless at after anesthesia extubation 5minutes,10minutes,15minutes,20minutes,25minutes.Results Compared with the control group,the systolic blood pressure and heart rate of the experiment group without statistical significance before anesthesia induction; after anesthesia induction,after operation,5min,at the end of operation,the systolic blood pressure and heart rate were lower(P<0.05); children recovery time,extubation time,recovery time of delivery from the anesthesia room were shorter(P<0.05); occurred rate of restless were lower after anesthesia extubation 5minutes,10minutes,15minutes,20minutes,25minutes(P<0.05).Conclusion Dexmedetomidine can prevent tonsillectomy after sevoflurane anesthesia result in the recovery period of restless.
