Predicting reflux after stomach sleeve surgery
This trial looks at how to predict who will develop acid reflux after a “stomach sleeve” operation. It may help doctors choose the safest plan before surgery and better prevent reflux afterward.
Orlando, FloridaAges 18 years+ - NCT04484727Recruiting
Measure lung pressure and breathing in ventilated ICU patients
This study measures lung pressures and breathing mechanics during planned or emergency breathing machine (ventilator) treatment. It may help doctors better understand lung behavior in both healthy and breathing-distressed lungs to improve care.
Gothenburg, Västra Götaland CountyAges 18 years+ - NCT04378400Enrolling by invitation
Check outcomes after laparoscopic sacrocolpopexy surgery
This study looks at short-term complications and longer-term results after laparoscopic sacrocolpopexy done at the study unit. It may help the clinic understand how well the surgery is working and how to improve care, based on follow-up questionnaires and check-ins.
LeuvenAges Any age - NCT04477967Recruiting
Creating a liver transplant biobank for children
This trial sets up a long-term collection of medical information and samples from children who have had a liver transplant. It helps doctors study outcomes over time and improve care for future patients.
Chongqing, Chongqing MunicipalityAges 1 month–18 years - NCT04257747Recruiting
3T MRI study of hand and forearm blood flow
This study uses a powerful MRI scanner (3 Tesla) to measure blood flow in the arteries of the hand and forearm under normal and certain medical conditions. You may qualify if you’re an adult and can safely have an MRI, either as a healthy volunteer or someone needing specific hand/arm surgery.
AmiensAges 18 years+ - NCT04266574Recruiting
Blood pressure–guided care for older or frail surgical patients
This study tests a goal-based blood pressure treatment approach during major surgery for people at higher risk (often older or frail with high blood pressure). The goal is to see if this BRAIN-targeted strategy can improve how patients do after surgery.
Rozzano, MilanAges 18 years+ - NCT04330651Recruiting
Extra-support machine for heart patients after surgery
This study looks at using an external life-support machine after heart surgery. It may help patients who need temporary extra support while the heart and body recover.
FlorenceAges 18–80 - NCT04273607RecruitingPhase 2/Phase 3
Test an ECMO approach without blood thinners for lung failure
This trial studies whether people on a breathing machine called VV-ECMO can be managed without routine blood thinners, to reduce bleeding risk. It is meant for adults with severe lung failure (ARDS) and checks that it is safe for you to avoid anticoagulation.
Toronto, OntarioAges 18 years+ - NCT04362709Recruiting
Post-surgery care study for people having brain surgery
This trial studies how to manage care after anesthesia for people having neurosurgery at Beijing Tiantan Hospital. It may help improve comfort and recovery planning after brain surgery.
BeijingAges Any age - NCT04303702Recruiting
Oxytocin during late labor to study childbirth changes
This study looks at how oxytocin, a medication that helps labor contractions, affects the second stage of labor. It may help researchers understand what leads to safer and smoother delivery for first-time mothers.
St Louis, MissouriAges Any age - NCT04183829Recruiting
Study of effects after early induced abortion
This study looks at pregnancy complications and outcomes after someone has an induced abortion in early pregnancy. It may help doctors better understand what to watch for in future pregnancies and how to reduce risks.
Zhongshan, GuangdongAges 18–40 - NCT04242069Recruiting
Lifestyle coaching for overweight women trying to conceive
This trial tests a lifestyle program (using a smartphone) to help overweight women improve health before pregnancy while trying to conceive within the next year. It may help you and your partner build healthy habits before pregnancy.
Québec, QuebecAges 18–40 - NCT04164173Recruiting
Breathing therapies after heart surgery for lung overinflation
This study looks at breathing (respiratory) therapies to help after certain heart surgeries that can cause the lungs to feel overly inflated. If you’re eligible, you may receive and be assessed for how well these breathing treatments work during your recovery.
Dallas, TexasAges 18–80 - NCT04246970Enrolling by invitation
Training program before and after liver transplant
This trial studies a structured exercise and training program before and after liver transplantation to help people recover better. You may be able to benefit if you’re getting an elective liver transplant and can safely participate in the training plan.
Valencia, ValenciaAges 18 years+ - NCT04209218Recruiting
Blood pressure and dexamethasone during lung cancer surgery
This study looks at how best to manage blood pressure during lung cancer surgery and whether giving dexamethasone (a steroid medicine) helps patients during the operation and recovery. You might benefit if you’re having longer lung cancer surgery and your heart and other organs are stable enough for the study.

Common questions
- Are there clinical trials for complication?
- Yes. Clin2 currently lists 1,076 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.
