ObjectivesTo determine the possible antiemetic effect of propofol as the single agent for intravenous anesthesia in children undergoing strabismus surgery, in comparison with other techniques.Patients And MethodEighty ASA I and II patients between 3 and 10 years, divided into 4 groups of 20, were studied prospectively. Groups I, II and III were premedicated with dehydrobenzylperidol (90 micrograms/kg) i.m. Group I then received sleep doses of thiopental and N2O. Group II received propofol, sleep doses, and N2O. Groups III and IV received sleep doses of propofol followed by intravenous perfusion (10 mg/kg/h).ResultsHalf the patients in group I experienced postoperative vomiting, more than in groups II, III and IV (p < 0.05). The incidence of vomiting in group II was 30%. Groups III and IV experienced less vomiting (5-10%) than did groups I and II (p < 0.05). The incidence of bradycardia during surgery was higher in groups III and IV (p < 0.05); medical treatment was not required.ConclusionsPropofol used as the single agent for induction and maintenance of anesthesia offers clear advantages in reducing emesis after strabismus surgery.
