dc.description.abstractOBJECTIVE To compare success and complication rates, based on staining of nerves and other structures, among three techniques of paravertebral brachial plexus blockade (PBPB) in dogs. STUDY DESIGN Prospective randomized design. ANIMALS A total of 68 thoracic limbs from 34 dogs. METHODS Limbs were randomly assigned to blind (BL) (n=24), nerve stimulator-guided (NS) (n=21), or ultrasound-guided (US) (n=23) technique. Injections were made with 0.3 mL kg-1 of lidocaine mixed with new methylene blue. Time to perform each block and Current used during NS technique were recorded. Dogs were anesthetized during the blocks and euthanized once completed. Dissections were performed to evaluate staining of nerves, spinal cord, mediastinum, pleura and vessels. An ANOVA and Tukey adjustment for time, logistic regression for association between current and nerve staining and generalized linear mixed model for staining of different structures were used. Significance was considered when p ≤0.05. RESULTS The median (range) number of nerves stained was 2 (0-4) with BL, 1 (0.3) with NS and 1 (0.4) with US guided technique. No significant differences in straining of C6, C8 and T1 or other structures were found among techniques. Nerve C7 was more likely to be stained by BL (p=0.05). Time to perform the blocks was significantly different among techniques, with mean ± CD duration in minutes of 3.6 ± 1.8 with BL, 6.3 ± 2.7 with US and 12.2 ± 5 with NS. The most common complication was staining of the spinal cord (29%, 38% and 39% with BL, NS and US, respectively).en
