The primary purpose of this three-arm single center, randomized, subject and assessor blind, controlled clinical study is to evaluate the effect of dexmedetomidine on patient-controlled intravenous analgesia after pediatric scoliosis orthopedics.
The study is a single center, randomized, subject and assessor blinded, controlled clinical study. Children who meet the inclusion/exclusion criteria will be evaluated. The patients will use a postoperative analgesic pump which is named as patient-control-analgesia (PCA) until the end of surgery with different dose of drugs. The control group will be set as using sufentanil only (0.05ug/kg/h infusion and 0.05ug/kg bolus). The experimental group will use sufentanil combined with different doses of dexmedetomidine. Low dose of dexmedetomidine PCA formula is 0.05ug/kg/h sufentanil with 0.05ug/kg/h dexmedetomidine infusion and 0.05ug/kg sufentanil with 0.05ug/kg dexmedetomidine bolus. High dose of dexmedetomidine PCA formula is 0.05ug/kg/h sufentanil with 0.1ug/kg/h dexmedetomidine infusion and 0.05ug/kg sufentanil with 0.1ug/kg dexmedetomidine bolus. Then patients will be followed until they discharge. The purpose of this trial is to evaluate the effect of of dexmedetomidine on patient-controlled intravenous analgesia after pediatric scoliosis orthopedics.
