Abstract | BACKGROUND AND OBJECTIVES: METHODS: Thirty volunteers received 5 injections each: (1) needle only, (2) bupivacaine 0.5%, (3) ropivacaine 0.5%, (4) bupivacaine 0.5% with dexamethasone 0.13 mg/mL, and (5) ropivacaine 0.5% with dexamethasone 0.13 mg/mL. The injections were made in the volunteers' upper trapezius muscles; there was a 15-minute interval between injections. The sequence of injections was randomized by Latin square design. The intensity of pain was rated on a 0 to 10 cm visual analogue scale (VAS) score. Neither the investigator nor the volunteer was aware of the nature of the injectate. The pH of the injected solutions was checked to determine if differences in the intensity of pain on injection were due to differences in the pH of the solutions. RESULTS: CONCLUSIONS:
