Vital capacity breath and tidal breathing techniques were compared for induction of anaesthesia with 7.5% sevoflurane in nitrous oxide, and oxygen. Thirty five subjects were randomly assigned to a vital capacity breath group (19) or to a tidal breathing group (16). The mean time for induction was faster with vital capacity breath (41 s) than with tidal breathing (52 s, p < 0.05). Some involuntary movements were seen in the tidal breathing group but none in the vital capacity breath group. Coughing was seen in a quarter of the subjects in the tidal breathing group and in one subject of the vital capacity breath group. The vital capacity group showed excellent characteristics: rapid, and pleasant induction without premedication. We conclude that the vital capacity breath technique is necessary for the inhalation induction of anaesthesia; it provides enough overpressure to allow the subject to pass reliably and rapidly through the initial stages of excitement.
比较了肺活量呼吸法和潮式呼吸法在以7.5%七氟醚与一氧化二氮及氧气混合进行麻醉诱导时的效果。35名受试者被随机分为肺活量呼吸组（19人）或潮式呼吸组（16人）。肺活量呼吸法诱导的平均时间（41秒）比潮式呼吸法（52秒，p<0.05）更快。潮式呼吸组出现了一些不自主运动，而肺活量呼吸组没有。潮式呼吸组四分之一的受试者出现咳嗽，肺活量呼吸组有一名受试者出现咳嗽。肺活量呼吸组表现出优异的特性：无需术前用药即可快速、舒适地诱导麻醉。我们得出结论，肺活量呼吸技术对于吸入麻醉诱导是必要的；它能提供足够的超压，使受试者可靠且快速地度过兴奋的初始阶段。
