PENG Block With Dexmedetomidine in Older Adults

Pain after hip surgery is a common problem in older adults and may delay early mobilization, increase the need for opioid pain medications, and contribute to complications such as delirium, nausea, or prolonged hospital stay. Regional anesthesia techniques are increasingly used to improve pain control while reducing the use of systemic opioids. The pericapsular nerve group (PENG) block is a modern ultrasound-guided regional anesthesia technique designed to provide effective pain relief after hip surgery while preserving muscle strength. It allows patients to begin mobilization earlier and may reduce the risk of postoperative complications, which is particularly important in older adults. Ropivacaine is a commonly used local anesthetic for nerve blocks. Dexmedetomidine is a medication that, when added in small doses to local anesthetics, may prolong pain relief and improve the quality of nerve blocks without significantly increasing side effects. However, the benefits and safety of adding dexmedetomidine to the PENG block in older adults have not been sufficiently studied. The aim of this randomized controlled clinical study is to compare the effectiveness and safety of two PENG block techniques in older adults undergoing hip surgery. Participants will be randomly assigned to one of two groups. One group will receive a PENG block with 20 mL of 0.2% ropivacaine. The second group will receive a PENG block with 20 mL of 0.2% ropivacaine combined with 25 micrograms of dexmedeto…
