Kim DH, et al. - Researchers here investigated whether the withdrawal reaction following rocuronium injection could predict the occurrence of emergence agitation (EA) in preschool-aged children undergoing inguinal herniorrhaphy. They also investigated grade of withdrawal reaction appropriate for identifying patients at risk of experiencing EA. They observed that following rocuronium injection during anesthesia induction, it was possible for withdrawal movement to reflect pain sensitivity of pediatric patients, which in turn could be valuable in identifying those at risk of severe EA on admission to the postanesthesia care unit (PACU) among preschool children undergoing inguinal herniorrhaphy.
