We have evaluated the effects of a single bolus dose of rocuronium 0.6 mg
kg-1 (group 1, n = 10) or vecuronium 0.1 mg kg-1 (group 2, n = 10) on
intracranial pressure (ICP), mean arterial pressure (MAP), cerebral
perfusion pressure (CPP) and heart rate (HR) in 20 neurosurgical patients
undergoing mechanical ventilation of the lungs during continuous sedation
with sufentanil and midazolam. Before and after neuromuscular block using
twice the ED90 of the blockers, ICP, MAP, CPP and HR were recorded
continuously for 15 min. Treatment caused no significant changes in ICP,
CPP or MAP and there was no evidence of histamine release. Mean maximum
block in the rocuronium group was slightly less than that in the vecuronium
group (95.9 (3.1)% vs 100%; ns) The difference between the two groups in
onset time (rocuronium 142 (62) s, vecuronium 192 (64) s; P = 0.04) was
significant. Patients in the rocuronium group showed a slight (7(4)%) but
significant (P = 0.003) increase in heart rate.
