Table 2. Free Fractions of the Enantiomers of Bupivacaine and Plasma Concentrations of AAG
Data are mean ± SD.
* Free fractions after 12 h differed from those at all other times (P < 0.01).
† Concentrations at each time differed from the concentrations at all other times (P < 0.01), except 0 versus 24 h (P > 0.05).
AAG =α1-acid-glycoprotein.
