What this trial studies

This clinical trial aims to compare the effectiveness of the Pericapsular Nerve Group (PENG) block versus the Interscalene Block (ISBP) in patients undergoing shoulder arthroscopy. It will assess various outcomes including the incidence of phrenic nerve block, duration of postoperative analgesia, time to first analgesic request, pain scores, and side effects. Patients will be randomly assigned to one of the two groups, and diaphragmatic movement will be evaluated using ultrasound before and after the procedure. The study will be conducted at Cairo University Hospital with a focus on ensuring patient safety and accurate measurement of outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 18 to 60 scheduled for shoulder arthroscopy with ASA status I or II.

Not a fit: Patients with severe cardiopulmonary disease, coagulopathy, or those on chronic opioid therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management techniques for patients undergoing shoulder surgery.

How similar studies have performed: Previous studies have shown promising results with similar regional anesthesia techniques, indicating potential for success in this approach.
