Correlation between Preoperative Anxiety and Emergence Agitation in Children after Sevoflurane Anesthesia / 华中科技大学学报(医学版)

ABSTRACT

Objective To investigate the correlation between preoperative anxiety and emergence agitation(EA)in children after sevoflurane anesthesia.Methods A total of 120 children who were going to receive an elective surgery were recruited in this study.The preoperative anxiety in these children was measured through the Modified Yale Preoperative Anxiety Scale(mYPAS)at the following timeduring the preoperative interview(T1),waiting period in surgery waiting room(T2),after the children entered the operating room(T3)and at the beginning of sevoflurane inhalation induction(T4).The emergence agitation(EA)scores were obtained by using the Pediatric Anesthesia Emergence Delirium(PAED) Scale after the surgery.Results After adjusting for the effect of age,it was found that the anxiety scores at T1 and T2 had no significant correlation with EA,while those in T3 and T4 showed a statistically significant correlation with EA.The level of anxiety at the beginning of induction showed a strong positive correlation with EA,and the correlation coefficient was 0.708(P<0.01).Conclusion The preoperative anxiety in the operating room and at the beginning of induction of anesthesia is correlated with EA in children receiving sevoflurane anesthesia.
