Registry for heart valve replacement anesthesia during TAVR
This study tracks patients who get a transcatheter aortic valve implantation (TAVR), a procedure to replace a narrowed heart valve without open-heart surgery. It looks at the type of anesthesia used during the procedure and records outcomes to learn what works best for patients.
Munich, BavariaAges 18 years+ - NCT02389673Recruiting
Radiation during breast surgery for low-grade DCIS
This trial studies giving radiation during surgery for women with a certain early breast condition called ductal carcinoma in situ (DCIS). It may help lower the chance that the DCIS comes back, especially when combined with breast-conserving surgery.
Guangzhou, GuangdongAges 18–70 - NCT02884271Recruiting
Study CPR during surgery when the heart stops
This trial looks at cardiopulmonary resuscitation (CPR) provided right in the operating room when a patient’s heart stops. It may help improve how emergency care is delivered during surgery.
IzmirAges Any age - NCT02977468RecruitingPhase 1
Pembrolizumab for early triple-negative breast cancer tumor changes
This Phase 1 study tests pembrolizumab (an immune medicine) to see how it affects the tumor and its surroundings in triple-negative breast cancer. It’s mainly looking at safety and early signs of benefit, especially in a limited, early-stage breast tumor.
Atlanta, GeorgiaAges 21–80 - NCT07417202Recruiting
Wound washing during surgery for pilonidal disease
This trial tests a special way of washing out the wound during surgery to treat pilonidal disease. It aims to help reduce infection or other problems after surgery.
Palo Alto, CaliforniaAges 8 months–30 years - NCT07425496Recruiting
Eye fluid dynamics study during surgery
This trial measures eye fluid flow during cataract or glaucoma surgery. It aims to help doctors predict and improve surgery results.
New York, New YorkAges 18 years+ - NCT07429916RecruitingEarly Phase 1
Ketamine for shoulder pain after weight loss surgery
This trial tests if a single dose of ketamine, given during surgery, can reduce common shoulder pain after laparoscopic gastric sleeve surgery. If you are having this weight-loss procedure and meet the weight and health criteria, this study may help improve your recovery.
IrbidAges 18–60 - NCT07431632Recruiting
Nerve freezing vs. epidural for pain after pectus excavatum repair
This study compares two ways to manage pain after pectus excavatum surgery: freezing the nerves during surgery (cryoanalgesia) versus an epidural block. The goal is to see which method provides better pain relief with fewer side effects.
São Paulo, São PauloAges 13 years+ - NCT07439679Recruiting
Anxiety Before Double Jaw Surgery and Your Recovery
This trial studies how anxiety before double jaw surgery affects your body during surgery and your recovery (pain, swelling, and ability to open your mouth). Researchers will use a simple anxiety questionnaire to see if feeling anxious changes your surgical experience.
IstanbulAges 18 years+ - NCT07449897Recruiting
Gallstone removal during gallbladder surgery study
This study tests a method to remove bile duct stones during gallbladder surgery, aiming to treat both problems in one procedure.
OsloAges 18 years+ - NCT07460037Recruiting
Brain signal study for speech recovery after stroke or injury
This trial uses a special brain-mapping test called high-density ECoG to study how people who have lost speech due to stroke, brain tumor, or ALS can be helped by reading brain signals when they imagine speaking. It may lead to new devices that let people with severe speech problems communicate using only their thoughts.
Hangzhou, ZhejiangAges 20–80 - NCT07463586Recruiting
Brain oxygen and confusion after surgery in older adults
This study looks at how giving extra oxygen during surgery affects brain function and confusion (delirium) in older adults. It involves placing a small sensor on your forehead to measure brain oxygen levels.
Seongnam-si, Gyeonggi-doAges 65 years+ - NCT07472959RecruitingPhase 4
Morphine for pain after heart bypass surgery
This study tests whether giving morphine during coronary artery bypass surgery can help control pain after the operation. It is for people having planned heart bypass surgery who are moderately sick and not already on strong pain medicines.
Istanbul, Outside of the USAges 18–80 - NCT07483151Recruiting
Heart Surgery and Thinking Changes Study
This study looks at how changes in blood flow (called venous congestion) after heart surgery might affect thinking and memory. It aims to find out if there is a link between how blood returns to the heart and brain function after surgery.
Yangzhou, JiangsuAges 18 years+ - NCT07489001Recruiting
Comparing opioid-free to standard anesthesia for back surgery
This study compares two types of anesthesia for lower back surgery: one that uses opioids and one that does not. The goal is to see which approach controls pain better with fewer side effects.
Istanbul, MaltepeAges 18–75 - NCT07491185Recruiting
How blood sugar control affects brain oxygen and recovery in diabetic surgery patients
This study looks at how well-controlled blood sugar (measured by HbA1c) affects brain oxygen levels during urologic surgery and how it impacts recovery afterward. It compares diabetic patients to non-diabetic patients to understand the role of blood sugar control in surgical outcomes.
IzmirAges 18 years+ - NCT07512232Recruiting
Rectal Lavage During Surgery to Lower Cancer Recurrence Risk
This trial tests whether rinsing the rectum with special fluid during minimally invasive surgery for mid-to-low rectal cancer helps prevent the cancer from coming back locally. The procedure aims to wash away cancer cells that might have leaked into the surgical area.
Guangzhou, GuangdongAges 18–75 - NCT07538648RecruitingPhase 1
Imaging Dye for Surgery to Find Solid Tumors
This study tests a new injectable dye (NC527-X) that helps surgeons see tumors better during surgery. The dye glows under special light, making it easier to find and remove cancer tissue completely.
Hangzhou, ZhejiangAges 18 years+ - NCT07589413Recruiting
Blood markers and fluid absorption during bladder cancer surgery
This study looks at how fluid absorbed during bladder cancer removal surgery affects cell-free DNA (tiny pieces of cancer DNA) in your blood. Researchers want to understand if these blood markers can help predict surgery outcomes and guide treatment decisions.
Lanzhou, GansuAges 18 years+ - NCT07609680Recruiting
Blood Pressure vs. Heart Output Monitoring During Colon Surgery
This trial compares two ways doctors monitor your body's circulation during colorectal surgery. One method tracks blood pressure; the other tracks how much blood your heart pumps. Researchers want to see which approach leads to better outcomes and fewer complications.

Common questions
- Are there clinical trials for intraoperative?
- Yes. Clin2 currently lists 272 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.
