A prospective, randomized, double-blind study was performed to evaluate the clinical efficacy of intradiscal steroid injections. Criteria for entrance were one-level internal disc disruption or nonsequestered nuclear prolapse with or without sciatica and a positive pain response on awake discography. Exclusion criteria were multilevel disease, central or lateral stenosis, prior lumbar surgery, or medical disease requiring systemic steroids. A total of 25 patients were randomly assigned to Treatment Group A (methylprednisolone, Depo-Medrol 80 mg/ml, The Upjohn Co., Kalamazoo, Michigan) or Treatment Group B (bupivacaine, Marcaine .5% 1.5 ml, Sanofi Winthrop Pharmaceuticals, New York, New York). Fourteen patients received Depo-Medrol, with 21% showing subjective improvement and 79% no improvement; 0% were clinically worse. Eleven patients received intradiscal Marcaine, with 9% showing clinical improvement and 91% no improvement; 0% were clinically worse. To quantify clinical response, a pain diagram grid score, a visual analog scale, and the Oswestry Pain Questionnaire were used before injection and 10-14 days after injection. No statistically significant benefit was identified in the use of intradiscal steroids.

A sensitive and selective high-performance liquid chromatographic (HPLC) method for the determination of bupivacaine and its two metabolites, desbutyl- and 4'-hydroxybupivacaine, in human serum and urine is described. Bupivacaine, both metabolites and the internal standard, etidocaine, are extracted with diethyl ether and then back-extracted into an acidic aqueous phase. After subsequent extraction into diethyl ether, evaporation and reconstitution in the mobile phase, bupivacaine and the metabolites are determined by HPLC using a reversed-phase C8 column with tetrahydrofuran-potassium phosphate buffer (8:92, v/v, pH 2.4) as the mobile phase. The sensitivity of the method is 10 micrograms/l for bupivacaine and both metabolites and the extraction efficiencies are 95, 54 and 92% for bupivacaine and desbutyl- and 4'-hydroxybupivacaine, respectively. The reproducibility of the method is good, the coefficients of variation varying between 1.8 and 7.4% in the concentration range 0.10-2.00 mg/l. The procedure was applied to human serum and urine samples from two elderly women who had been operated on under epidural analgesia (plain bupivacaine, 1.5 mg/kg) because of uterine prolapse.
