Most of the reports of fetal bradycardia and acidosis following paracervical block anesthesia have involved the use of amide-linked anesthetics, such as lidocaine and mepivacaine. The purposes of this study were (1) to determine placental transfer of an ester-linked local

A high-performance liquid chromatographic method has been developed for the simultaneous determination of chloroprocaine hydrochloride and its hydrolytic degradation product, 4-amino-2-chlorobenzoic acid. Separation is achieved using a mu-Bondapak C18 column and the eluant, water-acetonitrile-methanol-glacial acetic acid (74:20:5:1) containing 0.05-0.08% (w/v)

A sensitive and specific high-performance liquid chromatographic method for determination of the 2-chloroprocaine, local anesthetic of ester type, and its major metabolite 2-chloroaminobenzoic acid, has been developed and validated. A single-step extraction procedure is employed followed by high-performance liquid chromatographic
The purpose of this study was to identify the metabolic pathway of 2-chloro-4-aminobenzoic acid (CABA), a primary metabolite of chloroprocaine. Urine was collected from 4 healthy, pregnant women following the epidural administration of 600 mg chloroprocaine. The urinary metabolites were
