The purpose of this study was to identify the use of rapid-sequence induction (RSI) and its hybrids. For the study, 67 Certified Registered Nurse Anesthetists at 1 hospital completed a survey describing their experience using a modified technique for patients with a moderately increased risk of regurgitation and aspiration. Patient selection criteria and the use of aspiration prophylaxis, preoxygenation, cricoid pressure, and positive-pressure ventilation were evaluated. In contrast with routine induction and standard RSI techniques, the modified RSI technique consisted of aspiration prophylaxis, preoxygenation, application of cricoid pressure, and positive-pressure ventilation. The survey revealed that a modification of standard RSI is used commonly in clinical practice. These modified RSI techniques are not standardized, as variation was noted in the delivery of positive pressure ventilation. Further study is necessary to identify widespread use of modified RSI techniques and to clarify the risks and benefits of modified RSI.
本研究的目的是确定快速顺序诱导（RSI）及其混合技术的使用情况。在该研究中，一家医院的67名注册护士麻醉师完成了一项调查，描述了他们对反流和误吸风险中度增加的患者使用改良技术的经验。评估了患者选择标准以及预防误吸、预给氧、环状软骨压迫和正压通气的使用情况。与常规诱导和标准RSI技术相比，改良RSI技术包括预防误吸、预给氧、施加环状软骨压迫和正压通气。调查显示，标准RSI的改良方法在临床实践中普遍使用。这些改良的RSI技术并不标准化，因为在正压通气的实施过程中存在差异。有必要进行进一步研究，以确定改良RSI技术的广泛使用情况，并阐明改良RSI的风险和益处。
