Hasan ABMK, et al. - This study was carried out to determine the optimum time for intravenous cannulation after the induction of anesthesia with sevoflurane, oxygen, and nitrous oxide in children without any premedication. In such a pediatric population, before attempting intravenous cannulation, waiting for 1 minute 45 seconds (105 seconds) after the loss of eyelash reflex was recommended.
