Modified rapid-sequence induction of anesthesia: a survey of current clinical practice

S Schlesinger, D Blanchfield
AANA Journal 2001, 69 (4): 291-8
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.
