Methods: The study was performed in 40 patients over 65 yr of age. Anaesthesia was induced with thiopental, and maintained with sevoflurane in N2O/O2 and remifentanil. Cisatracurium 0.15 mg kg-1 or vecuronium 0.1 mg kg-1 were administered after induction. Intubation was attempted when neuromuscular block was 95%. Onset time, clinical duration of action, recovery index, spontaneous recovery time and tracheal intubation conditions were assessed. Haemodynamic parameters were also monitored. Results: The average ages of the patients were 72.5 ± 5.1 and 73.6 ± 6.3 in the cisatracurium and vecuronium groups, respectively. Onset time was significantly shorter after vecuronium, 158 ± 34s vs. 200 ± 50s, respectively. Recovery index was significantly shorter after cisatracurium, 19.5 ± 7.5s vs. 33.7 ± 18.6s (P < 0.05). Clinical duration and spontaneous recovery time were similar in both groups as well as haemodynamic variables. Conclusions: In elderly patients, vecuronium has a faster onset time while cisatracurium has a shorter recovery index under sevoflurane-remifentanil anaesthesia.EnglishAgedAnesthesia Recovery PeriodAnesthetics, InhalationAnesthetics, IntravenousAtracuriumBlood PressureDouble-Blind MethodFemaleHeart RateHemodynamic ProcessesHumansIntubation, IntratrachealMaleMethyl EthersMuscle RelaxationNeuromuscular Blocking AgentsNeuromuscular Nondepolarizing AgentsPiperidinesTime FactorsVecuronium Bromidecisatracuriumnitrous oxideoxygenremifentanilsevofluranethiopentalvecuroniumagedaginganesthesia inductionarticleclinical articleclinical trialcontrolled clinical trialcontrolled studydisease coursedouble blind procedureendotracheal intubationgeneral anesthesiahemodynamic monitoringhemodynamic parametershemodynamicshumanmuscle relaxationneuromuscular blockingrandomized controlled trialArticle10.1017/S0265021504000225
