Randomized Controlled Trial Comparative Study Clinical Trial[Mechanomyographic and electromyographic studies of endotracheal intubation with 2 different rocuronium dosages].
Rocuronium is a new, intermediate-acting, nondepolarizing relaxant with rapid onset of action leading to both good and very good intubation conditions. It was the aim of our study to investigate the onset of action, the intubation conditions and the course of relaxation using two different dosage regimes. Thirty consenting ASA 1 and 2 patients received either 0.6 mg/kg (2 x ED 95; group 1) or 0.06 mg/kg as priming dose followed by an intubating dose of 0.24 mg/kg rocuronium (group 2) four min later. ⋯ The clinical duration of action was significantly longer in group 1 (28.4 +/- 8.0 min) than in group 2 (14.8 +/- 2.5 min). It can be concluded that rocuronium which has shorter intubation times than atracurium and vecuronium is very useful for endotracheal intubation in both dosage regimes in long and very long lasting operations. Using the "priming principle" the patient has to be carefully controlled during priming time.
