Abstract:
BACKGROUND:Microdialysis is used to determine the concentrations of substances in the extracellular fluid of tissues. To date, it has not been used to measure rocuronium concentrations in human muscle. We determined the ability of microdialysis to recover rocuronium from muscle interstitial tissue for the purpose of assessing the effect of chronic phenytoin therapy on muscle concentrations of rocuronium. METHODS:In a first phase, an in vitro study was performed to establish the ability of the assay to recover rocuronium. In a second phase, 17 patients undergoing brain surgery were enrolled. Eight patients were on chronic phenytoin therapy and the remaining 9 patients were not taking any antiepileptic agent (controls). Rocuronium was administered intravenously and muscle tissue samples for microdialysis were collected. RESULTS:The recovery rate of the in vitro assay was 36% at a pump rate of 1 microL/min. Rocuronium muscle tissue concentrations could be measured in 25 microdialysate samples. Rocuronium concentrations were similar in patients treated with phenytoin and in controls, although the doses required to obtain a similar effect were significantly higher in patients on chronic phenytoin treatment. CONCLUSIONS:Quantification of drug concentrations in muscle by means of microdialysis is technically feasible in the clinical setting and it might help in studying pharmacologic mechanisms of drug action. Based on our results the decrease in the degree of effect of rocuronium in the presence of chronic phenytoin therapy might seem to be due mainly to a pharmacokinetic mechanism.
