ABSTRACT
To study the effects of fentanyl on the MAC of sevoflurane. Method:
One hundred and sixteen patients were given continuous infusion of fentanyl with CACI-pump (computer-assisted continuous infusion)to maintain different target plasma concentrations (Ct), meanwhile inhaled sevoflurane. All patients were randomly divided into seven groups receiving sevoflurane in oxygen with fentanyl target plasma concentration of 0?g/L (n=16), 0.5?g/L(n=20), 1?g/L(n=18), 2?g/L(n=16), 3?g/L(n=18), 4?g/L(n= 14) or 6?g/L(n= 14). Plasma concentraion of fentanyl was measured with radioimmunoassay. MAC determination, in response to the stimulus of skin incision, was made using the "up-down" method and logistic regression.Result:
The MAC of sevoflurane from group 1 to group 7 were 1.94%, 1.89%, 1.55%, 1.29%, 1.09%, 0.86% and 0.35% respectively.Conclusion:
We verify the MAC of sevoflurane, which is reduced by increasing plasma fentanyl concentration.
