AbstractThe aim of our randomized controlled study was to compare the neuromuscular characteristics of mivacurium and atracurium by evaluating the intubation conditions, intubation times, onset times and the duration of action of these two muscle relaxants using two different dosing principles. Forty-eight patients were included in this study. All patients were premedicated orally with 0.2 mg/kg diazepam. Anaesthesia was induced with 2.0 mg/kg propofol and 0.02 mg/kg alfentanil and maintained with 6 mg/kg/h propofol and 60% nitrous oxide in oxygen. Neuromuscular monitoring was carried out with supramaximal TOF-stimulation (2 HZ) of the ulnar nerve every 10 seconds and recording of the mechanomyogram (MMG) (Myograph 2000, Biometer) at the adductor pollicis muscle. The patients of group 1 (n = 12) received an intubation dose of 0.15 mg/kg mivacurium (2 x ED95) and the patients of group 2 (n = 12) received a priming dose of 0.015 mg/kg mivacurium (20% of ED95) followed by an intubation dose of only 0.07 mg/kg mivacurium (ED95) two minutes later. The patients of group 3 (n = 12) were intubated with 0.46 mg/kg atracurium (2 x ED95) and the patients of group 4 (n = 12) received a priming dose of 0.046 mg/kg atracurium (20% of ED95) and an intubation dose of 0.23 mg/kg atracurium (ED95) four minutes later. The patients were intubated under normocapnic conditions and following stabilisation of the palmar skin temperature after a 90% neuromuscular block (T1) had occurred. The intubation conditions were measured semiquantitatively using an intubation score.(ABSTRACT TRUNCATED AT 250 WORDS)
