Randomized Controlled Trial
Short-term inhalation of sevoflurane during induction of general anesthesia can inhibit the A-line ARX index response to intubation: a randomized trial.
Monitoring hypnotic depth is used to prevent awareness during general anesthesia. We used the A-line ARX index (AAI) to assess the effect of shortterm inhalation of sevoflurane in the prevention of intubation-induced inadequate hypnotic depth during anesthetic induction. ⋯ Adding 6% sevoflurane with 4 L/min O₂ for 3 minutes during the induction period prevented inadequate hypnotic depth caused by intubation but was not sufficient to inhibit fluctuations in hemodynamics.
