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 - NCT04577690RecruitingPhase 4
PECS pain study for children getting a chest device implanted
This trial tests a pain-control method (PECS) during surgery for children who are having a small chest device implanted. It may help reduce discomfort during and after the operation.
Toronto, OntarioAges 3–18 - NCT04600089RecruitingPhase 2
Ketamine during aortic surgery to help prevent spinal nerve injury
This Phase 2 study tests whether ketamine, given during a specific type of major aortic surgery, can help prevent spinal “nerve injury” (called spinal prophylaxis). You might be considered because your planned surgery and current plan for spinal protection match the trial’s needs.
Lexington, KentuckyAges 18–90 - NCT04646707Recruiting
Nerve block to reduce opioid use after neck spine surgery
This trial tests whether a targeted back/neck numbing injection (an erector spinae block) can help reduce the amount of opioid pain medicine needed after posterior cervical spine surgery. It also aims to support an “enhanced recovery” pathway so patients may recover more comfortably and potentially faster.
Toronto, OntarioAges 18–80 - 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 - NCT05260320Recruiting
Testing the best anesthesia plan for teens having jaw surgery
This study looks at whether a standardized anesthesia plan works best for kids and teens having Le Fort jaw surgery at Johns Hopkins. If you qualify, the team may use or adjust anesthesia to improve safety and comfort during surgery.
Baltimore, MarylandAges 14 years+ - NCT05271331Recruiting
Numbing injection options for back surgery pain
This trial compares two ways of numbing tissue during a planned back surgery called a laminectomy: an “ESPB block” versus numbing the wound directly. It aims to see which method works better for pain control and comfort after surgery.
Padova, VenetoAges 18 years+ - 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 - NCT05446636Recruiting
Circadian rhythm study for pain after C-section
This study looks at whether your body’s daily rhythm (“circadian rhythm”) is linked to pain after an elective C-section using spinal anesthesia. If you join, you’ll be monitored after surgery to see whether timing or rhythm-related factors change your pain.
Chongqing, Chongqing MunicipalityAges 20–45 - NCT05452694Recruiting
Personalized pain relief after back fusion surgery
This trial tests a personalized plan to manage pain after lumbar (lower back) fusion and decompression surgery. It may help reduce difficult pain while guiding safe use of opioids around the time of surgery.
Pittsburgh, PennsylvaniaAges 18–99 - NCT05525923Recruiting
Personalized pain plan after chest surgery in adults
This trial tests a personalized (tailored) plan to manage pain after thoracic (chest) surgery. It may help improve comfort and recovery by matching pain treatment to your situation after surgery.
Pittsburgh, PennsylvaniaAges 18–99 - NCT05543785Recruiting
Ketorolac pain block for lower-limb surgery with a tourniquet
This trial looks at whether a ketorolac pain medicine given directly to the leg during surgery can reduce pain after lower-limb orthopedic operations. It may help people who are having one leg operated on with spinal anesthesia and a tourniquet, but it has several safety limits.
Al MansurahAges 19–60 - NCT05662371Recruiting
Testing pain-monitor guided pain medicine during robot bowel surgery
This study checks whether using a pain-activity monitor during robot-assisted colorectal surgery can help the surgical team choose the right pain medicine. It may improve comfort and reduce the chance of giving too much or too little pain medicine.
AabenraaAges 18–80 - NCT05672784Recruiting
Knee numbing injections during knee replacement surgery
This trial compares two ways of numbing a knee area during planned knee replacement surgery: a nerve block alone versus a nerve block plus additional numbing medicine near the back of the knee. It may help doctors find which approach improves pain control and recovery while keeping side effects low.
ZagazigAges 21–60 - NCT05722002RecruitingPhase 4
Compare pain-med plans after low-risk surgery
This study tests which pain-medication plan works best and has the fewest side effects after certain low-risk surgeries. You may be assigned to receive opioid-based, NSAID-based, or acetaminophen-based pain control depending on your situation.
Ann Arbor, MichiganAges 18 years+ - NCT05746143RecruitingPhase 4
Zolpidem during recovery after lower-back fusion surgery
This trial studies whether taking zolpidem around the time of recovery from lower-back (lumbar) fusion surgery affects outcomes. It may help doctors understand how sleep medicine can (or can’t) support recovery in certain people.
Los Angeles, CaliforniaAges 18–75 - 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.
