The Effects Of Dexmedetomidine On Emergence Delirium In Pediatric Adenotonsillectomy Under TIVA

Objective:To observe the effects of dexmedetomidine on emergence delirium in pediatric adenotonsillectomy under TIVA.Methods:60 children patients undergoing adenotonsillectomy under TIVA were randomly divided into experimental group (group E) and control group(group C).Anesthesia was induced with propofol,remifentanil and vecuronium.Than dexmedetomidine was infused at the rate of 0.2 ug/kg.h in group E and sodium chloride was infused at the same volume in group C after induction. Record the time of operation,drug withdrawal to conscious,retention time of recovery room,and the modified Aldrete score of reaching recovery room, according to the Pediatric Anesthesia Emergence Delirium to mark the delirium of the patient in the future 30 minutes per 5 minutes,the highest score is used to effective value.and at the same time,mark the degree of pain according to the modified Children's Hospital of Eastern Ontario Pain ScaleResults:There was no statistical significance in comparation with group C and group E, the time of drug withdrawal to conscious,retention time of recovery room.and the modified Aldrete score of reaching recovery room(p>0.05).PAED of group E was significantly lower than group C(P<0.05), pain of group E was significantly lower than group C (P<0.05). Conclusion:Dexmedetomidine can decrease the incidence rate of emergence delirium in pediatric adenotonsillectomy under TIVA.
