Induction of anesthesia with sevoflurane, nitrous oxide, and oxygen: a comparison of spontaneous ventilation and vital capacity rapid inhalation induction (VCRII) techniques.
In this study, the vital capacity rapid inhalation induction of anesthesia (VCRII) technique and the conventional spontaneous inhalation induction technique, each using 4.5% sevoflurane in nitrous oxide and oxygen, were compared. The VSRII group (n = 32) and conventional group (n = 32) were each tested on unpremedicated volunteers. VCRII required only half the time of conventional inhalation induction (54 s and 108 s, respectively), and was not associated with cardiovascular instability. Each of the two techniques was found acceptable by most of the volunteers studied (more than 80%). However, sevoflurane is best used with the VCRII technique because VCRII resulted in fewer excitement movements that could lead to severe complications and pronounced excitement.
