Ultrasound-guided pericapsular nerve group block versus intravenous morphine for pain management in older adults with hip fractures: a randomised controlled trial in the emergency department

This study aimed to compare the analgesic efficacy of ultrasound-guided pericapsular nerve group (PENG) block versus intravenous morphine in managing acute hip fracture pain in older adults presenting to the emergency department. The results indicated that the PENG block provided significantly greater pain relief at 30 minutes and required no rescue analgesia, suggesting it is a more effective and safer alternative to intravenous morphine for this patient population.
