Fig. 2. There was a significant difference in the incidence of emergence agitation (EA) between the two groups at 5 min after arrival in the postanesthesia care unit (PACU) (3 vs. 12 patients, ^*P = 0.019). However, there were no differences at 20 min (23 vs. 19 patients, P = 0.425) or in the overall incidence (P = 0.102). The black stack presents the number of patients who showed EA. Group S: sevoflurane inhalation anesthesia induction group, Group T: intravenous thiopental anesthesia induction group.
