About

This study aimed to evaluate the analgesic efficacy of preoperative ultrasound-guided peri-capsular nerve group block (PENG) on postoperative analgesia after shoulder arthroscopic surgery.

Full description

Postoperative pain control after shoulder surgery is challenging, and poor pain management is invariably reflected in poor outcomes, with longer hospitalization and recovery time. The difficulty in reducing pain due to the complexity of shoulder innervation leads to conducting studies to explore selective axillary nerve blocks with a posterior approach or from the axillae.

The peri-capsular nerve group (PENG) block is a regional anesthetic technique. It can be effectively and safely applied under ultrasound guidance in shoulder surgery cases for postoperative analgesia. It targets only the sensory branches and not the posterior mechanoreceptors; there is a potential motor-sparing effect which is desirable for better physical therapy, and earlier discharge.
