Fig. 2. Nerve injury scores for sections obtained 7 days after intrathecal administration of 2.5% prilocaine (n = 30), 2.5% lidocaine (n = 28), or saline (n = 30). Nerve injury scores for each animal were based on all fascicles present in a cross-section 12 mm caudal to the conus medullaris. Each fascicle was assigned an injury score of 0–3, where 0 = normal, 1 = mild, 2 = moderate, and 3 = severe. The injury score for the animal was then calculated as the average score of all fascicles in the section. Data represent mean ± SEM. *P < 0.05 versus the other groups.
