PENG+LFCN Block vs QIPB for Total Hip Arthroplasty

This randomized clinical trial aims to evaluate and compare the analgesic efficacy and functional outcomes of the quadro-iliac plane block (QIPB) and the pericapsular nerve group (PENG) block combined with lateral femoral cutaneous nerve(LFCN) block in patients undergoing total hip arthroplasty. The primary outcome is the Numeric Rating Scale (NRS) within the first 48 hours after surgery. Secondary outcomes include postoperative total opioid consumption, ıncidence of quadriceps motor block, time to first ambulation, block performance time, falls, length of hospital stay, block- related complications(hematoma,local anesthetic systemic complications, vascular puncture, and infection), patient satisfaction assessed using a Likert scale, and incidence of postoperative nausea and vomiting.

Ultrasound-Guided PENG Block for Chronic Shoulder Pain

The purpose of this prospective, observational study is to evaluate the clinical and functional outcomes of ultrasound-guided Pericapsular Nerve Group (PENG) block in patients suffering from chronic shoulder pain. Chronic shoulder pain is a highly prevalent musculoskeletal problem that significantly restricts daily activities and diminishes the patient's quality of life. While conservative treatments and various interventional injections are widely used, long-term efficacy can be limited, and systemic side effects may occur. The shoulder PENG block is a novel regional analgesia technique that specifically targets the articular (sensory) branches of the nerves innervating the shoulder joint capsule without affecting the motor branches. In this single-center study, a total of 45 eligible adult patients with chronic shoulder pain who did not respond to conservative medical treatments will receive an ultrasound-guided PENG block as part of their routine clinical care. The procedure will be performed under sterile conditions using a combination of local anesthetic (lidocaine) and dexamethasone. Patient pain levels will be assessed using the Numerical Rating Scale (NRS), shoulder disability and functional status will be measured using the Shoulder Pain and Disability Index (SPADI), and overall patient satisfaction will be evaluated using the Global Perceived Effect (GPE) score. All parameters will be documented at baseline (before the procedure) and at follow-up visits on the 1st week, 4th week (1 month), and 3rd month post-procedure. The investigators aim to determine the efficacy, duration of effect, and safety profile of this intervention.

Comparison of Intermittent Bolus vs. Continuous Infusion PENG Block for Postoperative Pain in Hip Surgery

This retrospective study evaluates the effects of two different administration methods of the Pericapsular Nerve Group (PENG) Block on postoperative pain control, opioid consumption, and recovery in patients undergoing hip surgery. All patients in the study received: * PENG block via a catheter * Patient-Controlled Analgesia (PCA) with tramadol * Multimodal analgesia, including IV paracetamol and nonsteroidal anti inflammatory drugs (NSAIDs) as rescue analgesia The study compares two groups: 1. Intermittent Bolus Group: A researcher administered 20 mL of 0.25% bupivacaine every 4 hours. 2. Continuous Infusion Group: A pump delivered 5 mL/hour of 0.25% bupivacaine continuously. Both groups received the same total volume of local anesthetic over 24 hours. All PENG blocks were performed under ultrasound guidance at the end of surgery. This study aims to determine whether intermittent bolus or continuous infusion PENG block administration leads to better pain control, lower opioid consumption, and improved recovery outcomes.

COmparison of PENG Block and SIFICB in Hip Fracture Surgeries

The aim of this study is to compare the effectiveness of the PENG block and SIFIB in facilitating the positioning for neuroaxial anesthesia and their impact on the quality of postoperative analgesia.
