About

The study aimed to compare ultrasound guided pericapsular nerve group (PENG) block versus interscalene brachial plexus block for postoperative analgesia following shoulder arthroscopy.

Full description

Shoulder arthroscopy can effectively treat a number of injuries and diseases of the shoulder on an ambulatory basis. Although shoulder arthroscopy is considered minimally invasive, it is related to severe postoperative pain. The use of arthroscopy is popular because it decreases pain, shortens hospital stay, and improves patient satisfaction. However, immediate postoperative pain remains to be a problem in more than 40% of patients.

Regional anesthesia, especially peripheral nerve blocks have various advantages like decreased need for postoperative analgesics, decreased incidence of nausea and vomiting, shortened recovery time and hospital stay, Early ambulation and discharge.

Interscalene brachial plexus (ISB) block is considered the gold standard technique for pain management in shoulder surgery as it provides the most reliable analgesia. However, it has the potential for many complications. The most common of these complications is phrenic nerve palsy, which is reversible but may result in significant respiratory distress especially in patients with compromised respiratory function. Other less common yet serious complications include Horner's syndrome, recurrent laryngeal nerve block that may result in hoarseness of voice, vascular puncture, brachial plexus neuropathy, and unintended injection of local anesthetic into the subarachnoid space, epidural space, or vertebral artery.

Pericapsular nerve group (PENG) block is a new block that provides a pericapsular distribution with local anesthetic infiltration around the glenohumeral joint and provides analgesia by reaching the sensory nerve branches of the glenohumeral joint.
