The early placement of an intravenous (iv) line in children anesthetized with halothane has been shown safe and acceptable compared with later placement. However, there's not well known with sevoflurane use (2). The aim of the investigator's study is to determine whether one should make iv attempts during the early induction period (at 60seconds) or lately (90 or 120 s) and waiting until the child receives additional sevoflurane inhalation anesthesia

the investigators conducted a prospective randomized study, after obtaining Institutional review board approval, which didn't require written parental consent. Children age 1-12 years, undergoing elective general anesthesia via an inhalation induction were randomized to one of three groups of 30 patients each one, for iv placement, either 60s (group E), 90 or 120 s (group L) following loss of lid reflex. Movement on iv placement and incidence of laryngospasm were determined. Difficulty with iv placement was also recorded. Statistical analysis included contingency testing, ANOVA, and non parametric testing. A P-value <0.05 was considered significant.
