Rapid intubation with fazadinium and suxamethonium.

Fazadinium at two dose levels (1 mg/kg and 1.5 mg/kg) and suxamethonium at three dose levels (50 mg, 75 mg and 100 mg) were investigated in 106 adult patients to determine the time interval from injection to tracheal intubation. The intubating conditions were graded according to the scheme described by Lund and Stovner. Suxamethonium 100 mg gave the shortest time interval between the end of injection and intubation. There was no significant difference between the intubation time when smaller doses of suxamethonium (50 mg and 75 mg were used and those when AH8165 (1 mg and 1.5 mg/kg) were given. Suxamethonium 100 mg also produced a significantly higher incidence of excellent intubating conditions. The clinical implications of the findings are discussed.
