Table 1. Total and Unbound (Free) Plasma Concentrations of the Enantiomers of Bupivacaine and R (+)-/ S (−)-bupivacaine Concentration Ratios
Data are mean ± SD.
* Concentrations at each time differed from the concentrations at all other times (P < 0.01).
† Concentrations at each time differed from the concentrations at all other times (P < 0.01), except 24 versus 36 h (P < 0.05).
