Recruiting studies
- NCT07231926Recruiting
Spinal morphine for recovery after keyhole lung surgery
This trial tests whether giving a small dose of morphine into the fluid around the spinal cord (intrathecal) can improve pain relief and recovery after keyhole lung surgery. It aims to help patients feel better faster and have fewer complications.
ErzurumAges 18–70 - NCT07736989Recruiting
Pain block with vs without steroid for C-section
This trial tests two different pain-blocking injections given after a planned C-section. One has a steroid (dexamethasone) added to see if it gives longer or better pain relief.
IstanbulAges 18–50 - NCT06067893Enrolling by invitationPhase 4
Low dose sedation medicine for pain after scoliosis surgery
This trial tests a low dose of a sedative medicine, dexmedetomidine, given during and after spine surgery to see if it helps with pain. It is for teens and adults with scoliosis having back fusion surgery.
Kansas City, MissouriAges 10–21 - NCT05833048Recruiting
Pain-relief nerve block during cardiac surgery
This study tests whether a numbing “nerve block” placed in the rectus sheath area can reduce pain for people having certain heart surgeries with chest tubes. If you qualify, it may help your comfort during recovery, but it also depends on how suitable you are for local anesthesia.
New York, New YorkAges 18–85 - NCT07733128Recruiting
Pain relief with buprenorphine patch after lung surgery
This study tests a skin patch that releases buprenorphine, a pain medicine, to control pain after lung surgery. It may help reduce pain and the need for other pain medicines.
Santiago, Santiago MetropolitanAges 18 years+ - NCT07458360Recruiting
Front block for better recovery after hip replacement
This study tests if a special nerve block called the front block (pericapsular nerve group block) improves recovery after hip replacement surgery. You may be eligible if you are having hip replacement under spinal anesthesia and do not have certain health issues.
KonyaAges 18 years+ - NCT07188779RecruitingPhase 2
Impact of a special gel on tonsillectomy recovery in children
This trial tests whether applying a special gel called RADA16 to the surgical site after tonsillectomy (removal of tonsils) can help children heal better and with less pain. It may offer a new way to improve recovery after this common surgery.
Livingston, New JerseyAges 3–17 - NCT03037684Recruiting
Electrical skin stimulation for nerve and chronic pain
This trial tests whether painless electrical stimulation through the skin can reduce neuropathic pain or long-lasting pain after surgery. It may help some people by changing how pain signals travel in the nervous system.
NottwilAges 18–65 - NCT03596424Recruiting
Testing ketamine and dexmedetomidine during lung surgery
This trial studies whether the anesthesia medicines ketamine and dexmedetomidine can improve care during elective lung (video-assisted) surgery. It may help with comfort during and after the operation, depending on how these medicines affect pain and recovery.
Montreal, QuebecAges 18–80 - NCT03625011RecruitingPhase 4
Gabapentin before tonsil surgery to reduce pain
This trial tests whether giving gabapentin before pediatric tonsil (and possibly adenoid) removal can reduce postoperative pain. It may help children feel more comfortable after surgery while still being safe to use in the right patients.
Atlanta, GeorgiaAges 3–18 - NCT03715517Recruiting
Spinal anesthesia to improve recovery after liver surgery
This trial studies whether using spinal/epidural anesthesia during liver tumor removal surgery can help people recover better and with less pain. It compares this approach to standard general anesthesia care to see if recovery is smoother.
Winnipeg, ManitobaAges 18 years+ - NCT03756961Recruiting
Opioid-free care plan for people having weight-loss surgery
This trial studies whether an opioid-free or opioid-sparing care pathway can improve comfort and outcomes for adults undergoing laparoscopic weight-loss surgery. It may help people avoid side effects from opioid pain medicines while still managing pain safely.
Lindesberg, Region ÖrebroAges 18 years+ - NCT04219956Recruiting
Low-sugar diet aims to reduce belly-surgery pain
This study tests whether a special diet low in polyamines (a food-related substance) can reduce pain after major abdominal surgery. It compares pain control while you use a patient-controlled morphine pump or take opioid tablets by mouth after surgery.
BrestAges 18 years+ - NCT04576078RecruitingPhase 2
Nefopam for less pain after knee replacement surgery
This Phase 2 study tests whether oral nefopam can reduce pain after total knee replacement done with spinal anesthesia. It looks at whether this medicine works better than the usual post-surgery pain plan and how safely it can be used.
Lyon, LyonAges 18–75 - NCT04814082Recruiting
Compare two knee implant types for walking and function
This study compares two designs of knee replacement implants to see how they affect walking, function, and outcomes after surgery. You may be randomly assigned to one of the implant types used for your specific, approved knee replacement.
Baltimore, MarylandAges 18–75 - NCT04894864RecruitingPhase 4
Opioid-free anesthesia for elective abdominal aortic aneurysm surgery
This trial studies an “opioid-free” anesthesia and pain plan during planned open surgery for an abdominal aortic aneurysm. The goal is to see whether this approach reduces surgical stress and pain compared with usual care.
Heraklion, CreteAges 40–85 - NCT05351229RecruitingPhase 4
Spinal morphine for pain control after lung surgery
This trial tests whether putting morphine into the spinal area during lung surgery can reduce pain after surgery for people having certain minimally invasive lung operations. It aims to improve comfort and possibly reduce the need for other pain medicines.
Chicago, IllinoisAges 18–80 - NCT05824832RecruitingPhase 4
Buprenorphine, clonidine, and steroid to extend arm nerve block
This study tests whether adding certain medicines (buprenorphine, clonidine, and a steroid) to an arm “nerve block” during shoulder surgery can help the numbness last longer and improve comfort afterward. It is for adults having shoulder arthroscopy and compares how long the nerve block works.
Maywood, IllinoisAges 18 years+ - NCT05979493RecruitingPhase 4
Nerve block for pain after fibroid surgery
This study tests whether a nerve block (QL block) can help with pain after surgery to remove uterine fibroids while keeping the uterus. It may be a good option if you are having a laparoscopic myomectomy and want to manage pain without strong opioids.
Beachwood, OhioAges 18–45 - NCT06015165Recruiting
Pain control plan for complex anorectal surgery
This study tests a pain management plan led by anesthesiologists for people having complex anorectal surgery. The goal is to see if this approach can better control pain and improve recovery.
Beijing, Beijing MunicipalityAges 18–85 - NCT06075004Recruiting
Hip pain relief study comparing two injection methods
This trial tests two ways to give pain medicine around the hip joint during surgery to see which provides better pain relief. It may help patients experience less pain after hip replacement.
Santiago, Santiago MetropolitanAges 18–80 - NCT06182111Recruiting
Morphine during gallbladder removal
This study gives morphine during gallbladder removal surgery to see how it affects pain afterward. It may help you have less pain and recover more comfortably.
EsbjergAges 21 years+ - NCT06205355Recruiting
Pain measurement tool for jaw surgery patients
This study tests a device that measures your body's response to pain during jaw surgery. It may help doctors better manage your pain during and after the procedure.
SeoulAges 18 years+ - NCT06270147RecruitingPhase 2
Timing of nerve blocks for weight loss surgery pain
This trial tests whether giving a nerve block before or after bariatric surgery works better for pain control. It could help you have less pain and use fewer painkillers after your procedure.
Hamilton, OntarioAges 18 years+

- 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.
