Reported potential risks: real-time expert versus remote expert assessor (max n=103)
| Real-time expert | Remote expert | |
| Nerve injury/PONS (/67) | 5 (7.5%) | 0 (0%) |
| LAST (/71) | 3 (4.2%) | 0 (0%) |
| Pneumothorax (/16) | 0 (0%) | 0 (0%) |
| Peritoneum violation (/8) | 0 (0%) | 0 (0%) |
| Block failure (/92) | 4 (4.3%) | 8 (8.7%)* |
| Total (/254) | 12 (4.7%) | 8 (3.1%)* |
N.B. Despite 103 block feedback sheets return, not all feedback elements were completed by participants for all blocks (hence, n<103 for block failure).
*8/92 of all block views considered (7/8 of these views considered ‘inadequate’ by expert panel).
LAST, local anesthetic systemic toxicity; PONS, postoperative neurological symptoms.
