LPB Combined with QLB Using Single-needle Technique (LPQLB-SNT) for Hip Arthroplasty
China84 participantsStarted 2020-07-09
Plain-language summary
Total hip arthroplasty (THA) is one of the most successful orthopedic procedures to effectively relieve pain and restore function in patients with hip osteoarthritis, osteonecrosis of femoral head and hip fracture.The Lumbar Plexus Block (LPB) is currently used as the standard regional anesthesia technique to provide postoperative pain management after THA. The lumbar plexus (LP) originates from T12 to L5. In general, multiple-needle nerve blockade procedure is needed to block different branches of LP. Therefore, we need more time to finish the regional anethesia procedure and it's not easy for an inexperienced anesthesiologist to master the technique absolutely. In addition, multiple injections will increase the discomfort of the patients. We aim to investigate the effects of lumbar plexus combined with quadratus lumborum block using single-needle technique with Shamrock method as an alternative regional anesthesia.

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?
