The efficacy and safety of two inhalation techniques for mask induction using high concentrations of sevoflurane (8%) were compared in female patients planned for short gynecological procedures in an out-patient setting. One group (n = 20) received single breath vital capacity rapid inhalation induction (VCRII), the other group (n = 20) multiple deep breaths inhalation induction (DBI). The induction time was short and comparable in both groups (70 +/- 4 and 62 +/- 3 seconds respectively). The respiratory and hemodynamic side effects were also similar. The appreciation of the induction technique was comparable in both groups and most patients agreed to the same inhalation technique with a mask in future anesthetics.
