Tracheal intubation without muscle relaxants is usually performed with remifentanil and propofol or sevoflurane. Remifentanil to μg·kg-1 and propofol mg·kg-1 or sevoflurane up to Vol% provide acceptable, . excellent or good intubating conditions. We hypothesized that sevoflurane MAC would provide acceptable intubating conditions when combined with propofol and remifentanil. |
