A high-performance liquid chromatographic method with ultraviolet detection at 210 nm for quantitation of bupivacaine and two of its metabolites from plasma and urine is described. The compounds are extracted into n-hexane-isopropanol (5:1), evaporated and the reconstituted residue injected onto a reversed phase C18 column. Standard curves for all compounds were linear (r2 greater than 0.999) in the range 20-2000 ng/ml, with a limit of detection of 10 ng/ml. The inter-day coefficients of variation ranged between 2.7 and 12.2%. The method was applied to analyse bupivacaine and metabolite concentrations in patients on long-term epidural bupivacaine-fentanyl infusions.
本文描述了一种高效液相色谱法，用于定量检测血浆和尿液中的布比卡因及其两种代谢物，检测波长为210nm的紫外检测。化合物用正己烷-异丙醇（5:1）萃取，蒸发后将重构残渣注入反相C18柱。所有化合物的标准曲线在20-2000ng/ml范围内呈线性（r2大于0.999），检测限为10ng/ml。日内变异系数在2.7%至12.2%之间。该方法用于分析长期接受硬膜外布比卡因-芬太尼输注患者的布比卡因和代谢物浓度。
