The Analgesic Efficacy of Pericapsular Nerve Group Block (PENG) in Comparison With Periarticular Local Anesthetic Infiltration (PAI) Undergoing Hip Hemiarthroplasty : a Randomized Controlled Study

Not applicable Interventional Fayoum University Hospital · NCT06677606

This study is testing whether a new pain relief method called the PENG block works better than the PAI block for people recovering from hip surgery.

What this trial studies

This intervention compares the effectiveness of pericapsular nerve group (PENG) block versus periarticular anesthetic infiltration (PAI) block in managing postoperative pain for patients undergoing hemiarthroplasty after spinal anesthesia. Participants will be randomly assigned to receive either the PENG block or the PAI block. The study aims to determine which method provides better analgesic efficacy and motor-sparing effects. It will be conducted at Fayoum University Hospital, with patient enrollment starting in October 2024.

Who should consider this trial

Good fit: Ideal candidates are patients aged 50 to 90 years scheduled for elective bipolar hemiarthroplasty with ASA physical status I to III.

Not a fit: Patients who may not benefit include those with contraindications to spinal anesthesia, significant coagulopathy, or allergies to local anesthetics.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for patients undergoing hip hemiarthroplasty.

How similar studies have performed: While similar approaches have been explored, this specific comparison of PENG and PAI blocks in this context is relatively novel.
