Blood flow and mivacurium-induced neuromuscular block at the orbicularis oculi and adductor pollicis muscles.
We have studied the pattern of blood flow and pharmacodynamic profile of mivacurium-induced block at the adductor pollicis and orbicularis oculi muscles. We studied 30 adult patients anaesthetized with fentanyl, thiopentone, nitrous oxide-isoflurane, and mivacurium 0.2 mg kg-1. Neuromuscular transmission was monitored with accelerometry (TOF Guard, Biometer, Denmark). Blood flow was measured at...
متن کاملSimultaneous determination of neuromuscular block at the larynx, diaphragm, adductor pollicis, orbicularis oculi and corrugator supercilii muscles.
We simultaneously determined the neuromuscular blocking effect of mivacurium 0.2 mg kg(-1) at five muscles in 20 women undergoing gynaecological surgery. Evoked electromyographic responses were obtained using surface electromyography (EMG) at the adducting laryngeal muscles, the diaphragm (lateral to vertebrae T12/L1 or L1/L2) and the adductor pollicis muscle and acceleromyographic (AMG) respon...
متن کاملOnset of neuromuscular block at the masseter and adductor pollicis muscles following rocuronium or succinylcholine.
PURPOSE To compare the onset time of two different rocuronium doses (0.6 and 0.9 mg x kg(-1)) and succinylcholine (1.5 mg x kg(-1), preceeded by 0.06 mg x kg(-1) rocuronium) at the masseter and the adductor pollicis muscle. METHODS In a randomized study, 60 ASA I or II adult women, 18-65 yr of age, were anesthetized with propofol and fentanyl and nitrous oxide in oxygen. Neuromuscular monitor...
متن کاملA comparative study of the orbicularis oculi muscle to the adductor pollicis muscle during vecuronium neuromuscular blockade.
This study compared the orbicularis oculi muscle to the adductor pollicis muscle during vecuronium blockade. The orbicularis oculi muscle was found to be more resistant to and recovered from vecuronium neuromuscular blockade faster than the adductor pollicis muscle. Thus, caution should be utilized when assessing neuromuscular block with the orbicularis oculi muscle.
متن کاملMivacurium-induced prolonged neuromuscular block.
We report a case of prolonged neuromuscular block after administration of mivacurium 0.2 mg kg-1 to a 16-yr-old patient where the duration of block was 2.5 h. The interesting points in this case were that the patient had homozygous atypical plasma cholinesterase deficiency (both parents had a normal phenotype) following liver transplantation. Investigations showed low plasma cholinesterase acti...
