Rochester, MinnesotaAges 18 years+ - NCT05826990RecruitingPhase 2
IV antibiotic study for children with complex urinary tract infections
This study tests a new IV antibiotic combination (cefepime-enmetazobactam) for children with complicated urinary tract infections or kidney infections. The goal is to see how well it works and if it is safe.
Hradec KrálovéAges Up to 18 years - NCT05826925Recruiting
Care planning for women after pregnancy-related high blood pressure
This study tests ways to improve cardiovascular (heart and blood vessel) care for women after they had high blood pressure during pregnancy. It may help you get better guidance to prevent future heart problems.
Salt Lake City, UtahAges 18 years+ - NCT05843214Recruiting
Brain surgery monitoring with ultrasound and pupil checks
This trial tests non-invasive monitoring tools during brain surgery to track brain pressure and function. It may help doctors improve patient safety during operations.
Saint-PierreAges 18 years+ - NCT05836922Recruiting
Checking kidney oxygen after lung transplant to predict kidney injury
This pilot study looks at whether a painless skin sensor can measure kidney oxygen levels after lung transplant surgery. The goal is to predict and possibly prevent postoperative kidney failure by identifying risk early.
MarseilleAges 18 years+ - NCT05830721Recruiting
Monitoring leg pressure in adults on life-support
This trial tests a device that continuously measures pressure in an arm or leg to help detect compartment syndrome in people on a heart-lung machine (VA-ECMO). It may help clinicians act sooner if pressure becomes dangerous, potentially reducing complications.
Baltimore, MarylandAges 18 years+ - NCT05838690Recruiting
Improving breathing tube placement safety in NICU newborns
This trial focuses on newborns in the NICU who need a breathing tube placed through the mouth or airway. It aims to improve the success and safety of the first intubation while reducing risks.
Little Rock, ArkansasAges Up to 1 year - 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+ - NCT03999229RecruitingPhase 1
Nitric-oxide therapy during your own blood return
This early study tests whether a nitric-oxide–based treatment (given during autologous blood transfusion) can affect how well your body handles the returned blood. It mainly needs healthy adults who can safely donate blood and follow medication and breathing/comfort requirements.
Cleveland, OhioAges 18–35 - NCT05804188Recruiting
Testing safer breathing tube care in intubated children
This trial studies care during placing a breathing tube (tracheal intubation) in children having general anesthesia. It may help improve safety and outcomes around the breathing tube process.
Boston, MassachusettsAges Up to 16 years - NCT05783245Recruiting
Cooling therapy to reduce pain after open carpal tunnel surgery
This trial studies whether cooling (cold therapy) can lessen pain after open carpal tunnel release surgery. If you’re having this surgery, your answers to questionnaires and your current pain-medication status will determine whether you can join.
Chicago, IllinoisAges 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 - NCT05789108Recruiting
Study of first leg blood clot and long-term effects
This study looks at people having their first blood clot in the leg and how it can affect them long-term. It may help doctors better predict complications and improve follow-up care after an emergency visit.
Hvidovre, CopenhagenAges 18 years+ - NCT05769517Recruiting
Using ultrasound to predict BRCA genes from healthy ovaries
This study looks at whether pictures from a vaginal (transvaginal) ultrasound of a healthy ovary can help predict whether someone carries BRCA1 or BRCA2 gene changes. It may help identify people who could benefit from more genetic testing, without needing new ultrasound images.
RomeAges Any age - NCT05715814RecruitingPhase 3
Test diabetes-pill type medicine on kidney dialysis safety
