NCT07377877
This randomized controlled study aims to compare the effects of the external oblique intercostal block (EOIB) and the erector spinae plane block (ESPB) on postoperative analgesia in adult patients undergoing elective laparoscopic cholecystectomy. Both EOIB and ESPB are ultrasound-guided regional anesthesia techniques currently used in clinical practice to improve postoperative pain control as part of multimodal analgesia strategies. Laparoscopic cholecystectomy is a common minimally invasive surgical procedure; however, patients may still experience postoperative pain that can increase opioid consumption and delay recovery. Identifying the most effective regional anesthesia technique may improve postoperative analgesia and patient recovery. In this study, eligible patients will be randomly assigned to receive either bilateral EOIB or bilateral ESPB in addition to standardized general anesthesia and postoperative patient-controlled analgesia. Postoperative pain scores, opioid consumption, quality of recovery, postoperative nausea and vomiting, and block-related complications will be evaluated during the first 24 hours after surgery. The study aims to provide comparative clinical evidence regarding the analgesic effectiveness of these two regional anesthesia techniques.
NCT06834243
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.
