Comparison of postoperative analgesic efficacy between PENG block and suprascapular nerve block in shoulder arthroscopy: a randomized controlled trial

This study demonstrated that the PENG block, performed under ultrasound guidance, provided similar pain relief and opioid consumption reduction up to 36 hours postoperatively in various arthroscopic shoulder surgeries, including rotator cuff repair, Bankart repair, frozen shoulder, and impingement syndrome, compared to the SSNB. Given its shorter procedure time, less procedural pain, and similar clinical outcomes, the PENG block can be considered a good alternative to SSNB.
