Background: Em.rgence agitation (EA) is a com.on phenom.non observed in pediatric patients following general anesthesia. This study aim.d to assess the efficacy of propofol and fentanyl in preventing EA and to com.are their associated com.lications or side effects. m.thods: This prospective random.zed observational com.arative study was conducted at Dhaka m.dical College Hospital from.July 2013 to June 2014. The study aim.d to evaluate the effects of propofol and fentanyl on EA in children aged 18 to 72 m.nths undergoing circum.ision, herniotom., and polypectom. operations. Ninety children were included in the study, with 45 in each group. Patients with psychological or neurological disorders were excluded. Various param.ters including age, sex, weight, Am.rican Society of Anesthesiologists (ASA) class, duration of anesthesia, Saturation of Peripheral Oxygen (SPO2), heart rate (HR), respiratory rate (RR), Pediatric Anesthesia Em.rgence Delirium.(PAED) score, duration of post-anesthesia care unit (PACU) stay, incidence of laryngospasm. nausea, vom.ting, and rescue drug requirem.nt were com.ared between the two groups. Results: Age, sex, weight, ASA class, and duration of anesthesia were com.arable between the two groups. Perioperative SpO2 and HR were sim.lar in both groups. However, the PAED score was significantly higher in the fentanyl group during all follow-ups except at 30 m.nutes postoperatively. The m.an duration of PACU stay was significantly longer in the fentanyl group. Although the incidence of laryngospasm.was higher in the fentanyl group, it was not statistically significant. Conversely, nausea or vom.ting was significantly higher in the fentanyl group. The requirem.nt for rescue drugs was significantly higher in the fentanyl group com.ared to the propofol group. Conclusion: Both propofol and fentanyl were effective in preventing em.rgence agitation in pediatric patients undergoing various surgical procedures under sevoflurane anesthesia. However, propo
