BackgroundThis study was conducted to determine if a double-breath (DB) vital capacity (VC) rapid inhalation induction using immediate high-inspired concentration of sevoflurane is as well tolerated as a single-breath (SB) technique and if it results in a shorter induction time.MethodsA total of 104 children, ASA I-II, 6 year and above, undergoing elective surgery were randomly assigned to two groups: SB VC inhalation induction or DB VC inhalation induction with 8% sevoflurane in 66% nitrous oxide. The induction time, complications (cough, laryngospasm, breath-hold, movement, salivation) and level of satisfaction were documented.ResultsInduction was significantly faster in the DB group (41 +/- 9 s) compared with the SB group (50 +/- 14 s). DB inhalation induction was associated with fewer complications (15.4%) than the SB technique (50%).ConclusionsDouble-breath VC inhalation induction with 8% sevoflurane is as well tolerated as a SB technique and results in a faster onset of anaesthesia.
