Comparison of Spinal Anesthesia With Intrathecal Morphine Versus PENG Block With or Without Dexamethasone in Hip Arthroplasty
Poland90 participantsStarted 2026-06-01
Plain-language summary
The goal of this clinical trial is to learn which of three regional anesthesia approaches provides better pain relief and safety for older adults having planned hip replacement surgery. Researchers will study people aged 60 years and older who are scheduled for elective total hip arthroplasty.
The main questions this study aims to answer are:
Which 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.
Participants 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.
The results of this study may help doctors choose safer and more effective pain control strategies for people undergoing hip replacement surgery.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
