Chicago, IllinoisAges 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 - 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+ - 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 - 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+ - 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 - 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+ - 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+ - 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 - 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 - 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+ - 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+ - 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 - 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+ - NCT07864896RecruitingPhase 3
Study of a new pain medicine after knee replacement surgery
This trial tests a new oral pain medicine called suzetrigine for people who have a knee replacement. It aims to see if it helps control pain after surgery better or with fewer side effects than usual care.
New York, New YorkAges 18–80 - NCT07226700RecruitingPhase 3
Suzetrigine for pain after hip replacement surgery
This study tests an investigational pain medicine called suzetrigine to see how well it controls pain after total hip replacement surgery. It is for adults 18–80 who are having a first-time hip replacement and can receive spinal anesthesia.
New York, New YorkAges 18–80 - NCT04811209Recruiting
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.
