The Effects of Rapid Sequence Induction on Intubation Hypoxia
Patients were randomly allocated to receive either RSI, so rapid sequence induction or DSI which is delayed sequence induction. All of the intubations here were being performed by a second year postgraduate anesthetic resident. The primary outcome was the incidence of peri-intubation hypoxia and this was defined as an oxygen saturation of less than 93% any time from the onset of pre-oxygenation up until one minute after intubation. 35% of patients undergoing an RSI had an episode of hypoxia versus just 8% in the Delayed Sequenced Induction group. First past success was higher in theDelayedSequenceInduction group so 83%
