- Primary Outcome Measures
Name Time Method As primary outcome, plasma levels of ropivacaine were measured with high performance liquid chromatography before, 5, 10, 30, 60, and 180 min after the injection of ropivacaine. Plasma concentration of ropivacaine were analyzed with a high performance liquid chromatography photodiode array detection system (Agilent 1100 series, Agilent Technologies, Waldbronn, Germany). For quantification, drug-free serum was spiked at five different concentrations of ropivacaine (100, 200, 500, 1000, 2000 ng/ml). Ropivacaine concentration was calculated using linear regression. The limit of quantification of the method was 100 ng/ml.
