Recruiting studies
- NCT05635227Recruiting

CopenhagenAges 18 years+ - NCT06917859RecruitingPhase 1
Steroid to protect kidneys during heart surgery
This trial is testing whether a single dose of the steroid methylprednisolone, given before heart surgery, can protect your kidneys from damage during the operation. If you qualify, you'll receive the drug or a placebo, and your kidney function will be monitored closely.
Cairo, AbbasiaAges 18–65 - NCT07179029Recruiting
Can anesthesia affect the heart during non-cardiac surgery?
This study looks at whether anesthesia can cause heart damage during non-cardiac surgeries. If you have certain health risks, participating may help doctors learn how to better protect your heart.
TübingenAges 40–80 - NCT07172620Recruiting
Heart bypass surgery without clamping the aorta
This study tests a special technique for heart bypass surgery that avoids clamping the aorta. It may help people with hardened arteries in the aorta who need bypass surgery but are not good candidates for standard clamping.
Beijing, Beijing MunicipalityAges Any age - NCT04153994Recruiting
Numbing injection study for kids’ scoliosis back surgery pain
This trial tests whether a specific numbing injection (placed in the muscles of the back) can improve pain control for children having one-stage scoliosis surgery. It may help reduce post-surgery pain needs and improve comfort.
Palo Alto, CaliforniaAges Up to 18 years - NCT07164300Recruiting
Tranexamic acid dosing study in heart surgery
This study compares different doses of tranexamic acid, a medicine that reduces bleeding, in patients having planned heart surgery with a heart-lung machine. It aims to find the best dose to prevent blood loss.
IoanninaAges 18–99 - NCT06706258RecruitingPhase 2
Preventing kidney injury after heart surgery with a stomach acid drug
This trial tests whether giving a common stomach acid medication (a proton pump inhibitor) before, during, and after heart surgery can help prevent acute kidney injury. If you are at moderate to high risk for kidney problems after surgery, this study may be a good fit.
Houston, TexasAges 18–90 - NCT07079904Recruiting
Laser and ultrasound for IV placement in heart surgery
This trial tests a new method using laser and ultrasound guidance to place a small tube (IV) in a vein for patients having heart surgery. It may help make the procedure faster and safer.
Nanjing, JiangsuAges 18–80 - NCT07064954RecruitingPhase 2/Phase 3
Using your own platelets for complex heart surgery recovery
This study tests whether using your own donated platelets during heart surgery can help you recover better. Platelets are cells that help your blood clot, and donating them before surgery may reduce the need for donor blood.
Toronto, OntarioAges 18 years+ - NCT05481723RecruitingPhase 3
Lung ultrasound to guide fluid and blood pressure during surgery
This Phase 3 study tests whether using a lung ultrasound scan during surgery can better guide blood pressure and fluid needs. It may help stabilize patients during long operations and reduce complications related to poor circulation or fluid balance.
AmiensAges 18 years+ - NCT06128330RecruitingPhase 4
Bedside test for bleeding prevention drug in heart surgery
This study tests a quick bedside measurement of how well the drug tranexamic acid works to prevent bleeding during heart surgery. It may help doctors give the right dose to reduce blood loss.
BernAges 18–90 - NCT06968936Recruiting
Long-term outcomes of pre-surgery iron therapy
This study looks at long-term results of giving iron before major heart surgery to people with low iron levels. It aims to see if this treatment helps recovery and outcomes.
Hangzhou, ZhejiangAges 18–85 - NCT06814951Recruiting
Breathing & movement technique after heart bypass surgery
This study tests a special breathing and movement technique called the Thoraco-abdominal Rebalance Method to see if it helps people recover faster after heart bypass surgery.
Porto Alegre, Rio Grande do SulAges 35 years+ - NCT06722196RecruitingPhase 3
Amiodarone patch to prevent afib after heart surgery
This trial tests a biodegradable patch that slowly releases amiodarone directly onto the heart during surgery. It aims to prevent atrial fibrillation, a common irregular heartbeat after heart surgery.
Changchun, JinlinAges Any age - NCT06322810Recruiting
Pain relief methods for open heart surgery: ESP vs PIFB
This study compares two ways to manage pain after open-heart surgery. It looks at using an injection near the spine (ESP block) versus a needle placed through the chest wall (PIFB) to help reduce pain and the need for strong pain medicines.
Taichung, TaiwanAges 18 years+ - NCT06133842Recruiting
Brain blood flow and confusion after surgery study
This trial looks at how well the brain controls its own blood flow during non-cardiac surgeries. It aims to see if problems with this regulation are linked to confusion after surgery (delirium).
Boston, MassachusettsAges 60 years+ - NCT06012760Recruiting
Can iron and vitamin C reduce transfusions during heart surgery?
This trial is testing whether giving iron plus vitamin C before heart surgery can reduce the need for blood transfusions. It is for people with low iron and anemia who are scheduled for bypass or valve surgery.
Hangzhou, ZhejiangAges 18 years+ - NCT05999721Recruiting
Nerve block for better breathing after heart surgery
This trial is testing a nerve block (a numbing injection) placed near the breastbone to see if it helps your lungs work better after heart surgery. If you are having planned heart surgery through a breastbone cut, you may be able to join.
Petah TikvaAges 18 years+ - NCT05824260Recruiting
Study of risk factors for complications after major surgery
This study looks at patients who've had major abdominal, bone, or blood-vessel surgery to understand what factors make some people more likely to have complications afterward. It analyzes information already collected from hospitals to help doctors better predict and prevent problems.
AmiensAges 18 years+ - NCT05573633Recruiting
Smartwatch test to detect irregular heartbeats after heart surgery
This study checks whether a smartwatch can spot an irregular heartbeat called atrial fibrillation soon after on-pump heart surgery. If the smartwatch works well, it could help clinicians find the problem earlier after surgery.
AmiensAges 18 years+ - NCT05487612Recruiting
MiECC heart-lung machine vs standard bypass during heart surgery
This trial compares a newer heart-lung machine setup (MiECC) with the usual bypass technique during certain heart operations. It may help see whether MiECC changes outcomes like the need for blood transfusions or recovery after surgery.
TorontoAges 18–85 - NCT02573532Recruiting
Tracking heart damage after non-cardiac surgery
This study looks at whether patients experience heart muscle injury during or shortly after non-cardiac surgery. It aims to understand how common this is and what it means for recovery.
Basel, Canton of Basel-CityAges 45 years+ - NCT07708740Recruiting
Two doses of ketamine for preventing slow heart rate during eye surgery
This study tests whether two doses of ketamine (a medicine given through a vein) can reduce a reflex that slows the heart during eye surgery. If you are having eye surgery that involves moving the eye muscles, you may be eligible.
CairoAges 18–65 - NCT07511673Recruiting
