Pain relief options for gastric bypass surgery
This study compares two ways to manage pain after gastric bypass surgery: a nerve block alone versus a nerve block plus a lidocaine drip. The goal is to see which approach provides better pain relief and fewer side effects.
AlexandriaAges 18–60 - NCT07794852Enrolling by invitation
Ultrasound-guided spinal anesthesia for prostate surgery
This study tests a new way to give spinal anesthesia (numbing medicine injected in your back) for prostate surgery. It uses ultrasound to measure the fluid space around your spinal cord to find the right dose, which may make the anesthesia safer and more effective.
IstanbulAges 40 years+ - NCT07793266RecruitingPhase 1

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+ - NCT05830812Recruiting
Improve accuracy of lung cancer invasiveness diagnosis during surgery
This trial looks to improve how doctors judge how “invasive” a small lung adenocarcinoma is while you’re having surgery. Better accuracy may help guide treatment decisions for people with early-stage, operable lung cancer.
Wuhan, HubeiAges 20–80 - NCT06521710Recruiting
Nerve grafting to preserve erections after prostate removal
This trial tests if a nerve grafting technique can help preserve erectile function after robotic surgery for high-risk localized prostate cancer. It may be an option for men with good preoperative erectile function.
Montreal, QuebecAges 18 years+ - NCT07746505Recruiting
Remimazolam vs midazolam for anesthesia in older adults
This study compares two sedative medicines used to start general anesthesia in patients 65 and older having non-cardiac surgery. The goal is to see which one is safer and works better for older patients.
HangzhouAges 65 years+ - NCT07740577RecruitingPhase 4
Preventing nausea in emergency C-section patients
This study tests two common anti-nausea drugs for women having emergency C-sections under spinal anesthesia who haven't fasted. It aims to find the best way to prevent vomiting and nausea during surgery.
Sanliurfa, EyyübiyeAges 18 years+ - NCT06619002Recruiting
Using video to make uterine cancer surgery safer
This study is collecting videos from a type of minimally invasive surgery called sentinel lymph node dissection for endometrial or cervical cancer. The goal is to use deep learning (a type of artificial intelligence) to help surgeons identify important structures and any spread of cancer during the procedure, making the surgery safer and more effective.
RomaAges 18–99 - NCT07726134Recruiting
Diuretic use during kidney transplant to help the new kidney work faster
This trial tests whether giving a diuretic (a medication that helps flush fluids) during kidney transplant surgery helps a deceased-donor kidney start working sooner after the procedure.
London, OntarioAges 18 years+ - NCT07729319Recruiting
Heat and moisture during lung surgery: a study
This study looks at whether a special device that adds heat and moisture to the air you breathe during surgery can help people who have lung surgery through small incisions (VATS). If you are having planned lung surgery that requires one-lung ventilation, you may be able to join.
Istanbul, IstanbulAges 18–75 - NCT06427707RecruitingPhase 2/Phase 3
Adding propofol or ketamine to magnesium and lidocaine for nasal surgery
This trial tests whether adding propofol or ketamine to a standard combination of magnesium and lidocaine improves pain control and recovery for people having nasal surgery. It aims to find a better way to manage anesthesia and reduce side effects.
Cairo, Cairo GovernorateAges 18–60 - NCT07719075Recruiting
Norepinephrine dose for low blood pressure during emergency belly surgery
This trial tests whether a 5 microgram or a 10 microgram dose of norepinephrine works better to treat low blood pressure that happens after starting anesthesia or during emergency abdominal surgery. It may help doctors choose the right dose to keep your blood pressure stable.
Cairo, Cairo GovernorateAges 21–65 - NCT07712328Enrolling by invitationPhase 4
Desmopressin during complex sellar tumor surgery
This trial tests whether giving desmopressin (a drug that helps the body hold onto water) during surgery can prevent fluid and sodium balance problems in people having complex pituitary or sellar region tumor surgery. It’s designed for those at higher risk of these issues.
ShanghaiAges 18–75 - NCT07702487Recruiting
Warming before kidney surgery study
This trial tests if warming the body before kidney surgery can lower lactate levels, which may help recovery. It is for adults scheduled for a planned (not emergency) kidney removal.
Istanbul, SisliAges 18–90 - NCT06594289Recruiting
Liver surgery trial with special blood flow control
This trial tests a new way to control blood flow during laparoscopic liver surgery. It compares two methods to see which is safer and more effective for patients with certain liver conditions.
Guangzhou, China/GuangdongAges 18–70 - NCT07692425Recruiting
Neck vein test to predict blood pressure drop during surgery
This study tests whether checking how much the jugular vein (a vein in the neck) collapses can help predict drops in blood pressure during surgery. It's for older adults having laparoscopic colon or rectal surgery.
CairoAges 60 years+ - NCT06656949Recruiting
ICG injection for lymph node mapping in endometrial cancer
This trial tests whether injecting a dye called indocyanine green (ICG) in different spots can better find sentinel lymph nodes during surgery for endometrial cancer. It may help doctors remove fewer nodes and reduce side effects.
Jinan, ShandongAges 18–80 - NCT07683247Recruiting
Energy use during ACL reconstruction surgery
This study measures how much energy your body uses during ACL reconstruction surgery. It uses a special vest to track your heart rate and breathing, which may help surgeons understand how your body handles the operation.
LecceAges 16–49 - NCT07681245Recruiting
Real-time laser imaging for lung tissue during surgery
This study tests a new laser imaging device that works with artificial intelligence to quickly analyze lung tissue during surgery. The goal is to see if it can give as accurate results as the standard method, which could help surgeons make faster decisions during the operation.
Shanghai, Shanghai MunicipalityAges 18–90 - NCT07683299Recruiting

Common questions
- Are there clinical trials for intraoperative?
- Yes. Clin2 currently lists 284 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.
