[Effect of ephedrine on the intubation conditions using rocuronium versus succinylcholine].

Objective: The goal of this study was to determine if ephedrine could improve intubating conditions when it is administered before the muscle relaxant (rocuronium and succinylcholine).

Patients And Methods: In this prospective randomized double-blind study, 80 patients ASA I- II, scheduled for elective surgery, were allocated randomly to receive: succinylcholine 1mg/kg+ephedrine 70 microg/kg (Group I, n=20); rocuronium 0.6 mg/kg+ephedrine 70 microg/kg (Group II, n=20); succinylcholine 1mg/kg+0.
