Introduction: EA is characterized by agitation, inconsolable sobbing, disorientation, delusions, and hallucinations, decreased cognition and memory. Sevoflurane is widely used as an anesthetic agent for children because of its less pungent nature, lower solubility but it has a greater incidence of EA in preschool aged children. Propofol is a hypnotic amnestic agent with a short duration of action, commonly used for sedation, induction, and maintaining anesthesia and it has been used to prevent Emergence agitation. Aim of the Study: The aim of this study was to determine the efficacy of low dose propofol in reducing the incidence of EA at the end of face-mask sedation with sevoflurane. Methods: This was a prospective observational study and was conducted in the Department of Pediatric Anesthesia of Bangladesh Shishu Hospital and Institute, Dhaka, Bangladesh during the period from July, 2021 to December, 2021.In our study we took 220 children operated for hernia were randomized into two groups – Group A (Control group, n=110) and Group B (Propofol group, n= 110). Result: In total 220 patients from both the groups completed the study. In our study we found the mean age in group A & B was 6.3 ± 1.6 & 6.1 ± 1.9 years respectively. The mean PAED score was 14.41 ± 2.59 & 9.83 ± 3.51, the mean emergence time was 7.1 ± 2.0 & 13.4 ± 2.5, time in PACU was 44.5 ± 5.9 & 46.6 ± 7.6 mins in control & propofol group respectively. In contrast to the control group, no patient in the propofol group experienced EA beyond 15 or 20 minutes of emergence. Conclusion: In our study, we found that 0.5mg,/kg propofol was effective in preventing Emergence Agitation in children underwent herniotomy with caudal block and who’s sedation were maintained with sevoflurane.
