Randomized Controlled Trial Comparative Study Clinical Trial[Comparative study of inhalation induction by vital capacity breath in adults using 6% sevoflurane with oxygen or 4.5%sevoflurane in 50% nitrous oxide].
To evaluate the efficacy, side effects and hemodynamic characteristics of induction by vital capacity breath in adults using 6% sevoflurane and oxygen versus 4.5% sevoflurane and 50% nitrous oxide. ⋯ A vital capacity breath of 6% sevoflurane provided rapid induction. Induction was no more rapid when 50% nitrous oxide was added and the incidence of side effects did not decrease. Hemodynamic variables are stable during induction with sevoflurane with or without nitrous oxide, making this a well-tolerated alternative technique that is positively evaluated by patients.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparative study of two methods for laryngeal mask insertion].
To compare two ways of inserting laryngeal airway masks: uninflated and partially inflated to 75% of the volume, as recommended by manufacturers. ⋯ No differences were found between inflated insertion and Brain's uninflated insertion technique. We believe that inflated mask insertion might be useful when uninflated insertion proves impossible.
