Researchers will study people aged 60 years and older who are scheduled for elective total hip arthroplasty.\n\nThe main questions this study aims to answer are:\n\nWhich anesthesia method provides better pain control after surgery? Which method reduces the need for opioid pain medicines? Are there differences in side effects and recovery between the approaches? Participants will be randomly assigned to one of three groups. All participants will receive spinal anesthesia. One group will receive spinal anesthesia with intrathecal morphine. The other two groups will receive spinal anesthesia combined with a nerve block called the pericapsular nerve group (PENG) block, with or without the addition of dexamethasone.\n\nParticipants will have their pain levels measured at regular times during the first two days after surgery. Researchers will also record opioid use, time to first pain medication, ability to move after surgery, length of hospital stay, and any side effects such as nausea or itching. Blood tests will be used to measure markers of inflammation.\n\nThe results of this study may help doctors choose safer and more effective pain control strategies for people undergoing hip replacement surgery.",[92,93],"Arthropathy of Hip","Hip Osteoarthritis",[95],"total hip arthroplasty","NOT_YET_RECRUITING","2026-05-06",{"date":99,"type":100},"2026-05-13","ACTUAL",{"date":102,"type":86},"2026-06-01",{"date":104,"type":86},"2027-05-01",{"name":5,"class":6},1]
