  • A comparison of the onset and clinical duration of high doses of cisatracurium and rocuronium JOURNAL OF CLINICAL ANESTHESIA Lighthall, G. K., Jamieson, M. A., Katolik, J., Brock-Utne, J. G. 1999; 11 (3): 220-225


    To determine the onset and clinical duration of cisatracurium and rocuronium in equipotent doses in balanced opioid/isoflurane anesthesia.Randomized, controlled study.University hospital.40 healthy patients scheduled for elective surgery.Patients underwent anesthesia induction with thiopental or propofol with a cisatracurium intubating dose of either 0.15 or 0.2 mg/kg or a rocuronium dose of either 0.9 or 1.2 mg/kg. These doses correspond to three and four times the ED95 dose.The onset time and time to 25% recovery of baseline first twitch in a train-of-four were determined using an accelerometric sensor. Rocuronium had a faster onset time that cisatracurium at equipotent doses (3 x ED95: 134 vs. 220 sec respectively, and at 4 x ED95: 95 vs. 162 sec). Recovery tended to be faster, but not statistically different for cisatracurium compared to rocuronium.With equipotent intubating doses of rocuronium and cisatracurium, rocuronium produces a more rapid onset of muscle relaxation. The data suggest a tendency toward more rapid clinical recovery of cisatracurium compared to equipotent doses of rocuronium, although these differences were not statistically significant.
