Postoperative emesis in pediatric strabismus correction

ABSTRACT

Postoperative emesis after strabismus surgery continues to be a problem, despite the use of anti emetic. The purpose of this study was to identify an anesthetic technique associated with the lowest incidence of vomiting after pediatric surgery. A prospective, randomized, double-blind study was conducted to evaluate the effect of intravenous, sufentanil, morphine,or peribulbar block with propofol infusion on emesis in 105 pediatric patients undergoing strabismus correction. Anesthesia was maintained with air, oxygen and propofol infusion diclofcnac sodium 1mg/kg intramuscular was administered to all patients after induction patients was given either a peribulbar block, intravenous sufentanil 0.25 micro g/kg or intravenous morphine 0.1 mg/kg for perioperative analgesia. The emesis score was observed for the first 24 hours postoperatively. The incidence of emesis was significantly lower [1 of 352.9%] in the peribulbar group compared with morphine group [9 of 3525.6%] [P<0.1]. The sufentanil group had a higher incidence of vomiting [4 of 3511.4%] than did the peribulbar group. Among three techniques, peribulbar block with propofol - based anesthesia is the technique with the lowest incidence of postoperative emesis. Sufentanil-propofol is equally acceptable alternative however morphine- propofol is associated with high incidence of postoperative emesis
