What this Trial Is About
Researchers are evaluating pain control methods in elderly patients undergoing hip fracture surgery, focusing on comparing a femoral nerve block alone with a combination of pericapsular nerve group (PENG) block plus femoral nerve block. Hip fractures in older adults often cause severe pain, complicating anesthesia and recovery. This study aims to determine if adding the PENG block improves pain relief and reduces opioid use during and after surgery. Participants will be randomly assigned to receive either a femoral nerve block alone or a combined PENG plus femoral nerve block about 30 minutes before surgery. Both blocks are performed using ultrasound guidance with 20 mL of 0.25% bupivacaine. After the blocks, patients undergo spinal anesthesia for surgery. Researchers will monitor pain scores, opioid use, anesthesia procedure duration, sensory block onset, and hemodynamic stability throughout the perioperative period. During the study, patients’ pain levels will be measured at rest, during leg elevation, and while positioning for spinal anesthesia using the Visual Analog Scale. Opioid consumption and the need for additional analgesia will be tracked for 24 hours after surgery. Other assessments include heart rate, blood pressure, oxygen saturation, and time to first analgesic request. Patients will be observed in the post-anesthesia care unit and monitored for side effects related to opioids. The study results will help identify the best regional anesthesia strategy for pain management in elderly hip surgery patients.
