Appropriate Anesthesia Regimen to Control Sevoflurane-Induced Emergence Agitation in Children; Propofol-Lidocaine and Thiopental Sodium-Lidocaine: A Randomized Controlled Trial

Background: Emergence Agitation (EA) is a common problem in pediatric anesthesia. The current study evaluated the effect of intravenous lidocaine combined with propofol or thiopental sodium to control EA by sevoflurane in children. Objectives: The current study aimed to compare the effectiveness of two anesthesia regimen propofol-lidocaine and thiopental sodium lidocaine to control sevoflurane-induced emergence agitation in children. Patients and Methods:The study enrolled 120 children aged 12 to 36 months with retinoblastoma who underwent induction of anesthesia with sevoflurane for Eye Examination Under Anesthesia (EUA). Sampling was done at Rasoul-Akram Hospital in Tehran, Iran. The subjects were randomly assigned into four groups including: group one (thiopental sod ium-lidocaine [TL]), group two (thiopental sodium-saline [TS]), group three (propofol-lidocaine [PL]), and group four (propofol-saline [PS]). Emergence agitation was assessed by using a five-point scoring scale, every 10 minutes during the first 30 minutes after admission to the recovery room. Results: EA occurred in 24 cases (20%) of children. Incidence of EA in the TS, TL, PS, and PL groups were 21(70%),2(6.7%),1(33%), and 0 (0%), respectively (P < 0.001). Nausea and vomiting after anesthesia did not occur in any of the patients. After removal of the endotracheal tube, laryngospasm complication occurrence in the TS group (10 cases) was higher than the other groups and no statistically significant difference was observed (P=0.1). Conclusions: Propofol-lidocaine anesthesia regimen was more effective to control the pediatric emergence agitation than the other combinations.
