Block Visualization Scores Mean, standard deviation and distribution of block scores performed in patients randomized to PVB or PICB techniques. Scores were determined by anesthesiologists who were novice (a) or expert (b) at ultrasound imaging for regional anesthesia. Block scores were a sum of visibility of 5 elements, rated 0–3, including bony elements, pleura, ligament/membrane, needle, and local anesthetic spread, based on remote viewing of deidentified still images and short videoclip for each block. Both expert and novice reviewers rated PICB significantly higher (p = 0.008 expert, p = 0.01 novice, independent samples Mann Whitney U test)
