Recruiting studies
- NCT06963047Recruiting
Ultrasound to measure blood loss after C-section
This study tests whether a quick ultrasound after a C-section can better estimate blood loss than the usual visual method. If you are a woman who had a C-section, you may be eligible to help improve care for future mothers.

This study tests if using epinephrine and tranexamic acid together helps reduce bleeding and improve outcomes during knee replacement surgery. It may be a good fit if you are planning to have knee replacement and do not have certain medical conditions or allergies to these medicines.
Riyadh, Riyadh RegionAges 18–70 - NCT07111221Recruiting
Reducing bleeding risk before liver transplant
This trial tests a procedure to lower blood loss during liver transplant for patients with high blood pressure in the liver. It may help those who have had a previous transplant, abdominal surgery, or certain complications of liver disease.
WarsawAges 18 years+ - NCT07182045Recruiting
Blood loss during fibroid surgery study
This study tests if blocking blood flow to the uterus and ovaries during minimally invasive fibroid removal surgery helps reduce bleeding. It may be an option if you are having this type of surgery for large or numerous fibroids.
Houston, TexasAges 18 years+ - NCT07390864Recruiting
Comparing two drugs to reduce bleeding during fibroid surgery
This trial compares two medications (ergometrine and carbetocin) given during surgery to see which one is better at reducing bleeding while removing fibroids. Both drugs help the uterus contract to control blood loss.
Al Fayyum, Faiyum GovernorateAges 25–48 - NCT01731444RecruitingPhase 1
Phenylephrine gel to reduce bleeding in burn skin surgery
This early-stage study tests a medication (phenylephrine) used during burn wound surgery to help control bleeding. If it works, it may make skin grafting safer and reduce how much bleeding surgeons see.
Winnipeg, ManitobaAges 18–75 - NCT02314988RecruitingPhase 2/Phase 3
Tranexamic acid to reduce bleeding in spine surgery
This trial tests whether tranexamic acid (a medicine that helps blood clot) can reduce blood loss during long spine surgery after an injury. It may help lower the chance of needing transfusions and manage surgical bleeding.
San Francisco, CaliforniaAges 18–80 - NCT07414511Recruiting
Hemophilia A research study for pregnant families
This study follows pregnant people who carry a severe hemophilia A gene and their babies after birth. It looks at how hemophilia A is passed down and how it affects families, with the goal of improving understanding and care.
Seattle, WashingtonAges Any age - NCT07550114Recruiting
Nerve blocks to reduce bleeding and pain after spine surgery
This study compares two types of nerve blocks (numbing injections) given during lumbar spine fusion surgery to see which better reduces bleeding and pain after the operation. If you're having spine surgery, this trial might help your recovery be smoother with less pain and bleeding.
Barcelona, BarcelonaAges 18 years+ - NCT07335432Enrolling by invitation
Vitamin C to reduce blood loss during hysterectomy
This trial tests whether giving vitamin C through a vein before surgery can reduce blood loss during a total abdominal hysterectomy. If you are having this surgery and do not have bleeding problems or other exclusions, this study may help determine a way to make the procedure safer.
Si Racha, Changwat Chon BuriAges 20 years+ - NCT05312658Enrolling by invitation
Aortic compression during C-section to reduce blood loss
This trial studies whether gently compressing the major blood vessel in the abdomen during a C-section can reduce blood loss. It may help you stay safer during surgery, especially by lowering the chance of heavy bleeding.
StockholmAges 18 years+ - NCT02604563Recruiting
Aging, blood changes, and health in older adults
This study examines why some older adults develop changes in their blood cells that may affect their health. Researchers will look for links between these blood changes, aging, and common health problems in older people.
St Louis, MissouriAges 50 years+ - NCT06595407Recruiting
Loss of Y Chromosome in Aortic Stenosis Study
This study looks at how losing the Y chromosome in blood cells may be linked to aortic stenosis, a narrowing of the heart's aortic valve. It aims to understand why this condition may be more severe in men.
Charlottesville, VirginiaAges 40 years+ - NCT05312983Recruiting
Testing new hearing tests to better diagnose age-related hearing loss
This study is developing a set of hearing tests to more precisely identify age-related hearing loss. It may help you (or the study team) better understand what type of hearing problem you have and how to guide next steps.
ParisAges 18 years+ - NCT06492109Recruiting
Blood study on sleep loss
This study looks at blood samples to understand how sleep loss affects the body. It may help find new ways to diagnose or treat sleep problems.
Hangzhou, ZhejiangAges 18–80 - NCT06147843Recruiting
Study on weight loss in ALS patients from France and Germany
This study looks at why some people with ALS lose weight and what factors are involved. It follows patients in France and Germany to better understand weight changes and help improve care.
LilleAges 18 years+ - NCT06717334Recruiting
Lung cancer screening for people with unexplained weight loss
This study tests if low-dose CT scans can find early lung cancer in people who have unexplained weight loss. It aims to see if weight loss could be a sign that makes screening more useful.
Basking Ridge, New JerseyAges 50–80 - NCT07294131RecruitingPhase 2
Preventing muscle loss in hospitalized older adults
This trial tests a special exercise approach using blood-flow restriction and a video game to help older adults in the hospital keep their muscle strength. The goal is to find a safe way for bedridden patients to exercise and recover better.
AntwerpAges 65 years+ - NCT06565104Recruiting
Sleep study for people with high blood pressure
This study tests whether improving sleep can lower blood pressure. It is for people with elevated blood pressure or hypertension who speak English or Spanish.
New York, New YorkAges 20 years+ - NCT01927783Recruiting

This study tests a community-based behavioral weight loss program. It may help participants learn practical habits for healthier weight by working with people in local faith communities.
Bethesda, MarylandAges 19–85 - NCT06046651Recruiting
Blood sample collection for lab research
This study collects blood samples from healthy adults to help researchers learn more about how to run lab tests. It involves one visit or at-home collection and might help future medical research.
San Francisco, CaliforniaAges 18 years+ - NCT05449119Recruiting
Study links gut health, diet, and thinking and movement in seniors
This study looks at how differences in gut bacteria and nutrition may relate to changes in thinking and movement in people over 75 who have a reduced appetite (“small eaters”). It may help doctors better understand what could be contributing to these problems and how nutrition might play a role.

This study is looking for older adults (60–90) who are either cognitively normal, have mild cognitive impairment (MCI), or have mild-to-moderate Alzheimer's dementia. It aims to see how digital tests and blood-based markers relate to brain scans (amyloid and tau PET). You will need a study partner, undergo MRI and PET scans, and give blood samples.
