Recruiting studies
- NCT07588230Recruiting

Germantown, TennesseeAges 18 years+ - NCT06139666Enrolling by invitationPhase 4
Liposomal bupivacaine nerve block for rotator cuff surgery
This study tests whether a long-lasting numbing medicine called liposomal bupivacaine (Exparel) works better than standard pain relief for people having rotator cuff surgery. It aims to lessen pain after surgery so you may need fewer pain pills.
Camden, New JerseyAges 18 years+ - NCT05753046Enrolling by invitationPhase 4
Nerve-block during robotic prostate surgery to reduce pain
This trial studies whether a laparoscopic nerve block (called a TAP block) given during robotic prostate surgery can reduce postoperative pain. It compares comfort after surgery and looks for side effects or issues that could affect results.
Royal Oak, MichiganAges 18 years+ - NCT05444361Enrolling by invitation
Ultrasound freezing treatment for pain after mastectomy
This trial tests a “freezing” nerve procedure guided by ultrasound to help reduce pain after mastectomy. It aims to lessen postoperative pain by temporarily calming specific nerves involved in chest wall sensation.
Los Angeles, CaliforniaAges 18 years+ - NCT07450781Enrolling by invitation
How saline temperature and local anesthetics affect shoulder pain after gallbladder surgery
This trial tests whether warming the saline used during surgery or adding a numbing medicine can reduce shoulder pain after laparoscopic gallbladder removal. It also checks how these affect inflammation markers in the blood.
AlexandriaAges 18–65 - NCT07467291Recruiting
Comparing Nerve Blocks for Pain After Lung Surgery
This study compares two types of nerve blocks—SPSIP and SAP—to see which one works better for pain after a type of lung surgery called VATS. If you are having this surgery and match the criteria below, you may be able to join this trial to help doctors find the best pain relief method.
ElâzığAges 18–65 - NCT07070050RecruitingPhase 4
NSAIDs after laparoscopic surgery: continuous or bolus?
This study compares giving NSAID pain relievers continuously through an IV versus as single doses (bolus) after laparoscopic surgery to find which method provides better pain relief with fewer side effects.
Moscow, Moscow OblastAges 18 years+ - NCT07463430Enrolling by invitationPhase 4
Suzetrigine for pain after non-mastectomy breast surgery
This trial tests a new pain medication, suzetrigine, for people having breast surgery (not mastectomy) who are expected to have moderate pain. It checks if this drug works well compared to standard options.
San Diego, CaliforniaAges 18 years+ - NCT04273828Recruiting
Study of muscle changes in chronic low back pain surgery
This study looks at how muscle degeneration relates to nerve-related symptoms in people with chronic low back pain. You may be eligible if you’ve tried non-surgical care but still need surgery to relieve nerve pressure.
São Paulo, São PauloAges 18 years+ - NCT05150795RecruitingEarly Phase 1
Testing pregabalin before surgery versus fentanyl during surgery
This trial compares two medicines used around the time of surgery—pregabalin given by mouth before surgery versus fentanyl given during surgery—to see which better controls pain after the operation. You might join if you’re a generally healthy surgical patient and aren’t using certain related medicines.
CairoAges 21–45 - NCT07185594RecruitingPhase 2/Phase 3
Study of a new pain drug after abdominal surgery
This trial tests a new medication called HRS-2129 for managing pain after abdominal surgery. It is for adults who will have moderate to severe pain after their operation, and aims to see if the drug can help control that pain safely.
Zhengzhou, HenanAges 18 years+ - NCT04094701Recruiting
Study of opioid needs after hip arthroscopy surgery
This study looks at how much pain medicine (opioids) people actually need after hip arthroscopy and what factors may affect it. It may help improve safer, more personalized pain control after surgery.
Chicago, IllinoisAges 18–80 - NCT06088420Recruiting
Pain relief after cesarean section with nerve blocks
This study compares different nerve blocks for pain control after a planned cesarean delivery. The goal is to find which block provides the best pain relief with fewer side effects.
Asyut, ManfaloutAges 18–40 - NCT06216717Recruiting
Study of electrode location for brain stimulation in chronic pain
This study looks at where electrodes are placed in the brain for people who have a device that stimulates the motor cortex to treat chronic nerve pain. The goal is to help improve how these devices are positioned for better pain relief.
Nice, Alpes MaritimesAges 18 years+ - NCT06721819RecruitingPhase 3
Sleep and brain training before heart surgery to prevent delirium
This study tests whether a combination of sleep therapy, brain games, and light exercise before heart surgery can help prevent confusion or disorientation (delirium) after the operation. Participants will be asked to use a tablet and fitness tracker daily for about an hour before their surgery.
Boston, MassachusettsAges 60 years+ - NCT07226700RecruitingPhase 3

Testing better pain control and recovery after orthopedic surgery
This trial looks at how well a pain-control plan works after certain orthopedic surgeries and how it affects recovery and patient-reported outcomes. It may help determine what level of pain relief is meaningful to patients after surgery.

Common questions
- Are there clinical trials for chronic postoperative pain?
- Yes. Clin2 currently lists 297 recruiting chronic postoperative pain studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a chronic postoperative pain trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a chronic postoperative pain trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
