Randomized Controlled Trial[Effects of different fresh gas flow on pharmacodynamics of isoflurane during anesthesia induction].
To investigate the effect of different fresh gas flows (FGFs) on the pharmacodynamics of isoflurane during anesthesia induction. ⋯ Between the completion of tracheal intubation and beginning of the surgery, 1% or 2% Co under a moderate FGF (1-3 L/min) may guarantee the patients' unconsciousness, but hypotension is less likely under a relatively low flow (1-2 L/min) than a higher flow (3 L/min). Higher FGF and Co result in faster induction of deep anesthesia and higher incidence of hypotension.
