The interaction indices between rocuronium and gentamicin on single twitch and tetanic fade. They are lower than 0.9 for 0.2 and 0.5 mM gentamicin in single twitch. For 0.1 mM gentamicin, the indices are between 0.67 and 1.02; the interaction is synergistic or additive (A). The interaction indices are lower than 0.9 in 0.2 and 0.5 mM gentamicin for tetanic fade. In 0.1 mM gentamicin, the indices are between 0.87 and 0.94; the interaction is synergistic or additive (B). The values are reported as the mean and the SD. GM represents gentamicin.
