This trial looks at how to predict if a laparoscopic appendectomy (keyhole surgery to remove the appendix) will be more difficult. It uses information from before surgery to help doctors and patients prepare.
Shanghai, Shanghai MunicipalityAges Any age - NCT06357546Recruiting
Avoiding a bladder tube during planned c-section
This study looks at whether it is safe to skip placing a urinary catheter (a tube in the bladder) during a planned cesarean section. The goal is to see if this can lower discomfort and the risk of infection without causing problems.
MontpellierAges 18 years+ - NCT06015711Recruiting
Does a pre-surgery painkiller reduce strong IV pain meds needed?
This trial tests if taking Maxigesic® (a combination of two pain relievers) before surgery can lower the amount of a strong IV pain medicine called remifentanil needed during anesthesia. It may help patients have a smoother recovery with fewer side effects.
Suwon, Gyeonggi-doAges 19–60 - NCT05898581Recruiting
Compare two pain block methods for hip replacement surgery
This trial studies whether one type of numbing injection (a PENG block) works better than another method (local anesthetic injected into the surgical area) to control pain during and after total hip replacement. It may help choose the best pain plan for people having a specific surgical approach.
London, OntarioAges 19 years+ - NCT06498700Enrolling by invitation
Preventing PTSD After Brain Surgery: Ketamine vs Dexmedetomidine
This study tests whether giving a low dose of ketamine or dexmedetomidine during brain surgery can help prevent post-traumatic stress disorder (PTSD) afterward. Both medicines are safe and used to manage pain and anxiety.
Zagazig, Sharqia ProvinceAges 18–60 - NCT06446648RecruitingEarly Phase 1
Green dye to improve recovery after prostate cancer surgery
This trial tests whether using a green dye (ICG) during robot-assisted prostate removal helps preserve urinary and sexual function. It is for men with localized prostate cancer and good baseline erectile function.
Orange, CaliforniaAges 18 years+ - NCT06275542Enrolling by invitation
Removing breathing tube without standard monitoring device
This study tests if it is safe to remove the breathing tube after surgery based on oxygen levels without using a special nerve monitor. It may help find a simpler method for deciding when to take the tube out.
YogyakartaAges 18–60 - NCT06296277Recruiting
Breathing machine use during surgery
This study looks at how a breathing machine is used during surgery. It is for adults who need help breathing while under general anesthesia for their operation.
Alessandria, ItalyAges 18 years+ - NCT05971719Recruiting
Testing an air “sniffer” using aerosol glycerine during lung surgery
This trial checks whether a new system can detect and pinpoint tiny air leaks during lung transplant surgery. It uses a glycerine mist during the operation, which may help surgeons find leaks and repair them sooner.
MontrealAges 18 years+ - NCT04730609RecruitingPhase 4
Dexmedetomidine to reduce shaking during scheduled C-section
This trial tests whether dexmedetomidine, a calming medicine, can reduce unwanted shaking (shivering) during a planned C-section done with spinal anesthesia. It may help make the surgery and recovery more comfortable.
Rochester, MinnesotaAges 18 years+ - NCT04454203RecruitingPhase 4
Local anesthetic catheter to reduce tourniquet-related blood pressure spikes
This Phase 4 trial tests whether a local anesthetic catheter placed near a nerve and artery can prevent high blood pressure caused by a tourniquet during total ankle replacement surgery. If it works, it may make recovery safer and more comfortable for some patients.
Durham, North CarolinaAges 18–75 - NCT04523701RecruitingPhase 3
Testing a “white test” to find bile ducts during liver surgery
This trial studies whether a simple “white test” using a special lipid (fat-like) solution can help the surgical team spot open bile ducts early during liver removal. Finding them sooner may help prevent bile leakage after liver surgery.
AarauAges 18 years+ - NCT06756672Recruiting
Helping with recovery in laparoscopic colorectal surgery
This study looks at how a system called HPI (a way to track your body's response during surgery) might help people recover better after laparoscopic colorectal surgery. It is for people having this planned surgery who do not have serious heart or lung problems.
TaipeiAges 20 years+ - NCT03713528Enrolling by invitationPhase 4
Antibiotic placed in bone to help save an infected knee implant
This trial tests whether putting antibiotics directly inside the bone during surgery can improve outcomes for an infected knee prosthesis when the implant is being kept. It may help more people avoid needing full implant removal and replacement.
San Francisco, CaliforniaAges 18 years+ - NCT07440199Recruiting
Comparing two pain blocks for lung surgery without a breathing tube
This study compares two different pain-blocking techniques for a specific type of lung surgery. It aims to see which one provides better pain relief for patients who are awake during the procedure.
ElâzığAges 18–65 - NCT06393062Recruiting
Urine test after kidney stone surgery
This trial checks whether a simple test on the first urine after kidney stone surgery can help find infections early. It only includes adults having a specific type of stone removal who are infection-free before surgery.
AdıyamanAges 18 years+ - NCT07610824Recruiting
Lung Pressure and Recovery After Robot-Assisted Prostate Surgery
This study measures breathing pressure during robot-assisted prostate removal surgery and checks lung function after surgery using ultrasound. It aims to understand how surgery affects your lungs and recovery.
Ankara, AnkaraAges 18–80 - NCT07608861Recruiting
Numbing Block to Reduce Pain Medicine During Nose Surgery
This study tests whether a special numbing injection in the upper jaw (bilateral maxillary block) helps reduce the amount of pain medication needed during septorhinoplasty—a surgery to reshape the nose and straighten the septum. The goal is to find ways to use less strong pain medication during surgery.

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.
