Comparing muscle relaxants in kidney disease patients during surgery
This trial compares two muscle relaxants, rocuronium and cisatracurium, to see which causes fewer complications in people with chronic kidney disease (not on dialysis) who need general anesthesia. If you have kidney disease and are having surgery that requires a breathing tube, this study may help determine the safer drug for you.
Galveston, TexasAges 18–80 - NCT07065734RecruitingPhase 4

PortoAges 18 years+ - NCT06950957Recruiting
Comparing two airway devices for septoplasty
This trial compares a video laryngeal mask with a breathing tube during septoplasty (nose surgery) to see which works better. If you are having this surgery, you may be able to join.
Samsun, IlkadimAges 18–65 - NCT06782776Recruiting
Doppler ultrasound for twin pregnancy risk
This study uses a special ultrasound technique called Doppler echoflowmetry to measure blood flow in mothers pregnant with twins. The goal is to find early signs that might predict complications, so doctors can offer better care.
Bologna, BolognaAges 18–44 - NCT07317596Enrolling by invitationPhase 3
Comparing two treatments to reduce pain after wisdom tooth surgery
This trial compares two treatments, methylprednisolone and hyaluronic acid, given during wisdom tooth removal to see which one helps reduce pain and swelling afterward. You may participate if you need a special type of impacted wisdom tooth removed and are generally healthy.
SanaaAges 18–40 - NCT03688295RecruitingPhase 3
Testing the best antibiotic length after laparoscopic appendix surgery
This study compares whether you need antibiotics after laparoscopic surgery for a complicated, “localized” appendix infection. It aims to find the safest, most effective antibiotic approach after surgery.
AmiensAges 18 years+ - NCT06245317Recruiting
New ventilation method for children having laparoscopic surgery
This trial compares a special ventilation method (PCV-VG) to standard care during laparoscopic surgery in children. It aims to see if it helps them breathe better during the procedure.
Asyut, Asyut GovernorateAges 1–8 - NCT06740773Recruiting
Risk factors for problems after skull repair surgery
This study looks at people who had a skull repair surgery (cranioplasty) to see what problems might happen afterward. Researchers want to find out what factors raise the risk of complications so they can help future patients recover more safely.
Chongqing, Chongqing MunicipalityAges Any age - NCT06550479Recruiting
Comparing three types of arm fistulas for dialysis
This trial compares three types of surgical connections (fistulas) between an artery and a vein in the arm, used for dialysis. It looks at which type works best for people with advanced kidney disease who need a new access point for dialysis.
WroclawAges 18 years+ - NCT06541002Recruiting
SHIFT app for stem cell transplant survivors' sexual health
This trial tests a mobile app (SHIFT) designed to help people who have had a stem cell transplant and are experiencing sexual health concerns. It aims to see if the app can improve your well-being.
Coral Gables, FloridaAges 18 years+ - NCT05490225Recruiting
Test device to make dialysis fistulas easier to stick safely
This trial tests a small implant device that can make dialysis fistulas easier to access with needles when normal needle access is too difficult or risky. It may help reduce painful failed attempts and needle-related complications for people with certain types of fistulas.
Dothan, AlabamaAges 18 years+ - NCT06412081Recruiting
Lung ultrasound to guide physical therapy for breathing problems
This study tests whether using lung ultrasound can help guide physical therapy for hospitalized patients with new breathing problems. It aims to make therapy safer and more effective by seeing how the lungs look in real time.
Brussels, Brussels CapitalAges 18 years+ - NCT06396767Recruiting
Breathing test before heart surgery to predict lung problems
This study uses a simple breathing test before scheduled heart surgery to see if it can help predict breathing or lung complications after the operation. The results may help doctors identify patients who need extra support during recovery.
London, OntarioAges 19–99 - NCT06348719Recruiting
Robot vs. standard laparoscopy for early endometrial cancer
This trial compares two types of minimally invasive surgery (robot-assisted vs. conventional laparoscopy) for removing the uterus in people with early-stage, low- to intermediate-risk endometrial cancer. The goal is to see which approach offers the best value and outcomes.
LilleAges 18 years+ - NCT07729319Recruiting
Heat and moisture during lung surgery: a study

Common questions
- Are there clinical trials for complication?
- Yes. Clin2 currently lists 1,140 recruiting complication 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 complication 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 complication 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.
