Personalized anesthesia plan to protect the brain during heart surgery
This trial studies whether tailoring anesthesia and monitoring the brain’s blood-flow control during heart surgery can improve neurological outcomes (brain-related function and recovery). It may help by guiding anesthesia in a more individualized way and checking how well the brain is protected during the operation.
BaselAges 65 years+ - NCT05163639RecruitingEarly Phase 1
Noninvasive brain and spinal training for spinal cord injury
This early study tests a noninvasive way of training the nervous system to see how it affects “associative plasticity,” or the brain/spinal cord’s ability to change with practice. It may help researchers learn strategies that could improve function for people with spinal cord injury.

Distractions in the operating room and their effect on care
This study looks at what happens in the operating room during colorectal surgery, such as distractions and how the team works together, to see if these affect patient safety.
AthensAges 18 years+ - NCT07794618Recruiting
Video review of safe appendix surgery for children
This study looks at videos of appendix removal surgery in children to see if they can help make surgery safer. If your child is having this surgery, the video may help doctors learn how to prevent problems.
Kayseri, KayseriAges 5–17 - NCT05828862Recruiting
Checks blood-pressure drops during major upper stomach surgery
This trial studies what happens when blood pressure drops during planned (elective) major upper gastrointestinal surgery and looks at related blood chemistry. Your care team may collect samples during the operation to understand why this happens and how to improve outcomes.
TaipeiAges 20–80 - NCT07713121Recruiting
Keeping blood pressure up during surgery to prevent confusion in older adults
This trial tests whether keeping blood pressure at 85 mmHg or higher during surgery can reduce confusion (delirium) after surgery. It is for older adults with high blood pressure who are having non-cardiac surgery.
HamburgAges 65 years+ - NCT05648474Recruiting
Nerve monitoring during a low-back fusion surgery
This study tests whether special nerve monitoring during a low-back fusion helps make surgery safer and the results easier to judge. It’s for people having a specific type of low-back fusion on one or two levels.
Carlsbad, CaliforniaAges 18 years+ - NCT07687095Recruiting
Music during breast surgery and anesthesia use
This trial tests whether listening to music during breast surgery can reduce the amount of anesthesia medication needed. If you're having breast surgery and can use headphones, this study may help make your experience more comfortable.
Bursa, BursaAges 18–70 - NCT07656857Recruiting
Flexible brain sensor study for epilepsy surgery
This trial tests a new flexible brain sensor to help guide surgery for people with drug-resistant focal epilepsy. It aims to find exactly where seizures start so surgeons can remove that area safely.
Beijing, Beijing MunicipalityAges 3–60 - NCT07638579Enrolling by invitation
Nerve monitoring methods during thyroid and parathyroid surgery
This study compares two ways to monitor nerves during thyroid or parathyroid surgery to see which method works better. During surgery, doctors use electrical sensors to make sure they don't accidentally damage important nerves in your neck.
ThessalonikiAges Any age - NCT06778811RecruitingPhase 4
Sleep quality study for heart surgery patients
This trial studies sleep problems before and after heart surgery. It tests two medicines to see if they can help improve sleep. This may help you recover better after surgery.
Nanjing, JiangsuAges 40–75 - NCT01485575Recruiting
Blue or green dye eye surgery to help remove retinal tissue
This trial studies an eye surgery technique that uses a colored dye (blue or green) to help the surgeon carefully remove a thin inner retinal layer. It may help make the procedure more precise and safer, and the study compares how the dye-assisted method works.
LinzAges 18 years+ - NCT07396636Recruiting
Using machine learning to manage low blood pressure during surgery
This study tests whether an AI tool can help doctors better manage low blood pressure during planned surgeries. If you are having an elective surgery with general anesthesia and need an arterial line for monitoring, this trial may be for you.
Konya, Konya/MeramAges 18 years+ - NCT07349784Recruiting
Automated lung opening steps during laparoscopic surgery
This trial tests a computer-controlled method to open collapsed lung parts during laparoscopic colorectal cancer surgery. It aims to improve breathing and reduce complications after surgery.
Istanbul, BakırkoyAges 18–80 - NCT07339475Recruiting
Using vein size to predict blood pressure drops in older adults during hip or leg surgery
This study uses an ultrasound to measure the size of a vein in your leg before surgery to see if it can predict a drop in blood pressure during the procedure. If you are over 60 and having planned lower-limb surgery with spinal anesthesia, this non-invasive test might help your doctors prepare for your care.
CairoAges 60 years+ - NCT07315308Recruiting
Nerve block before heart surgery and painkiller use
This study tests whether a numbing injection in the chest before heart surgery can reduce the amount of pain medicine needed during the operation. It may help you manage pain better and recover more comfortably.
Gaziantep, SahinbeyAges 18–65 - NCT07301307Recruiting
Blood pressure and fluid management during surgery
This trial tests a new tool that helps doctors manage fluids and blood pressure during surgery. It uses a special index (HPI) and computer-assisted fluid management to keep your blood pressure stable, which may reduce complications.
Athens, AtticaAges 18 years+ - NCT07250399Recruiting
Pain after root canal treatment with different tools
This trial compares two different ways of cleaning a tooth's root canal to see which causes less pain during and after treatment. It is for people with severe tooth pain in an upper premolar.
CairoAges 20–50 - NCT06291714Recruiting
Non-invasive blood pressure prediction during major surgery
This trial tests a new, non-invasive way to predict drops in blood pressure during major hip, knee, pelvis, or spine surgery. The goal is to help doctors prevent low blood pressure, which can lead to complications.
GiessenAges 45 years+ - NCT06911528Recruiting

Common questions
- Are there clinical trials for intraoperative?
- Yes. Clin2 currently lists 283 recruiting intraoperative 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 intraoperative 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 intraoperative 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.
