Timing of oxytocin in second stage of labor
This study looks at when oxytocin is started during the pushing phase of labor to understand if timing affects outcomes for the mother and baby.
HaifaAges 18 years+ - NCT06038487Recruiting
Early vs. standard timing for upper jaw implant dentures
This trial compares placing implants in the upper jaw immediately versus waiting for healing, to see which approach works better for people who already wear full dentures. You may qualify if you have no upper teeth and your jawbone is healthy enough for implants without extra bone grafts.
Cleveland, OhioAges 21 years+ - NCT05966116Recruiting
MRI study of brain salt buildup in people on dialysis
This study looks at whether salt (sodium) builds up in the brain in people with kidney failure who are on long-term dialysis. It uses MRI scans to better understand what’s happening in the brain and may help guide future care.
DerbyAges 50–75 - NCT05959252RecruitingPhase 2
Bivalirudin vs heparin for blood thinning during ECMO
This Phase 2 trial compares two blood-thinning medicines—bivalirudin and heparin—in people on ECMO (a machine that supports breathing and/or circulation). It aims to see which medicine works better and is safer while you are connected to the ECMO circuit.
Sydney, New South WalesAges 18 years+ - NCT06025240Recruiting
Better antibody monitoring after kidney transplant
This study tests a new way to monitor harmful antibodies after a kidney transplant. It may help prevent transplant rejection over time.
Liverpool, MerseysideAges 18 years+ - NCT05992857Recruiting
Omentum wrap to prevent leaks after Whipple surgery
This trial tests if wrapping a flap of abdominal tissue (omentum) around the arteries during Whipple surgery (pancreaticoduodenectomy) can reduce the risk of a serious leak. It may help patients who have a higher fistula risk score (7 or more) during their open surgery.
ClichyAges 18 years+ - NCT05950724Enrolling by invitationEarly Phase 1
TNF blocker to protect lungs after transplant
This early-stage trial tests whether blocking a specific inflammation signal (TNF-alpha) can help prevent or improve kidney problems and early graft (new lung) dysfunction after a lung transplant at Northwestern. You might be eligible if you’re scheduled for that transplant and are willing to go through study consent and follow-up.
Chicago, IllinoisAges 18 years+ - NCT05934682Recruiting
Study of surgery outcomes in children
This study looks at how pediatric patients do after different types of planned and unplanned surgeries at participating hospitals. It may help doctors improve care and safety for children undergoing surgery.
São Paulo, São PauloAges 1 day–18 years - NCT05782543Recruiting
Testing improved kidney repair outside the body during transplant
This trial tests a machine method that keeps a donated kidney working “outside the body” so it may be better repaired before transplant. It is designed for certain first/second kidney transplants using specific donor types and storage methods.
Groningen, Provincie GroningenAges 50–100 - NCT05814094Recruiting
Testing a red blood transfusion approach during ECMO
This study looks at whether giving red blood cell transfusions in a specific way is practical and safe for people receiving ECMO (a heart-lung support machine). It’s mainly a feasibility study, meaning the goal is to see if the plan can be carried out smoothly and safely.
Camperdown, New South WalesAges 18 years+ - NCT05345821Recruiting
Study of side effects and satisfaction after silicone breast implants
This trial follows women who get their first breast implant surgery or a repeat (primary vs secondary) and records side effects and how satisfied they feel. It aims to better understand safety and satisfaction with smooth-surface silicone implants.
Santo André, São PauloAges 18 years+ - NCT05618392Recruiting
Pain check after feeding tube placement
This trial studies how much pain people feel after a radiology-guided feeding tube is placed through the skin while you’re awake with local numbing medicine. It also looks at factors that might help predict pain, to improve comfort for future patients.
ValenceAges 18 years+ - NCT05268120Recruiting
Treatment to clear MRSA in people with difficult carriage
This study tests ways to get rid of MRSA bacteria in the body when it is “complicated,” such as having MRSA outside the nose or an ongoing MRSA infection. It may help reduce future MRSA problems or infections by lowering how long the bacteria stay in your body.
LeidenAges 18 years+ - NCT05388682Recruiting
Treating Takayasu disease with lung artery involvement
