Effects of remifentanil and propofol total intravenous anesthesia on pediatric adenotonsillectomy

Objective:To investigate the effects of remifentanil and propofol total intravenous anesthesia on tracheal intubation and hemodynamics,and to observe the characteristics of postoperative recovery on pediatric patients undergoing adenotonsillectomy.Methods:40 pediatric patients(5～10 years old,ASAI) were randomly divided into 2 groups:group R(remifentanil+ propofol total intravenous anesthesia),group F (fentanyl+propofol total intravenous anesthesia),each group included 20 cases.The variation of blood pressure,heart rate,oxygen hemoglobin saturation(SpO_2) were observed at four time points:5 minutes before operation(T1),just after tracheal intubation(T2),the time when cutting out the gland(T3) and just after operation(T4).The duration and the characteristics of postoperative recovery were investigated too.Results:In group R,compared to T1,blood pressures at T2,T3 and heart rates at T2 and T3 were decreased(P0.05).In group F,blood pressures at T3,heart rates at T3 and T4 were higher than T1 (P0.05).The recovery duration in group R was(5.6±2.3) min,which was faster than group F(14.2±5.7) min.There was no fidgetiness during resuscifation time in group R,but the postoperative pain was more obvious.Conclusion:On pediatric patients undergoing adenotonsillectomy,remifentanil and propofol total intravenous anesthesia could efficiently restrain harmful stress.They could also maintain hemodynamic stability,the recovery duration and quality were better too.This kind of anesthesia method was ideal during pediatric adenotonsillectomy.
