Recruiting studies
- NCT05937789Recruiting

Colatina, Espírito SantoAges 18 years+ - NCT07085455Recruiting
Timing of IV nutrition in critically ill patients
This trial tests whether giving IV nutrition (supplemental parenteral nutrition) at different times helps critically ill patients who are not getting enough calories from tube feeding alone. It may improve recovery for people with organ failure in the ICU.
Changchun, JilinAges 18 years+ - NCT06822231Recruiting
High-tech rehab for acute neuromuscular diseases
This study tests a high-tech rehab program using robots and advanced tools to help people recover from acute neuromuscular diseases. It aims to see if this approach improves leg strength and mobility better than standard care.
BariAges 18–80 - NCT06721923Recruiting
Comparing protein delivery methods in critically ill children
This study looks at whether giving protein continuously or all at once is better for children in intensive care. The goal is to find the most effective way to support recovery.
Vancouver, British ColumbiaAges 1–11 - NCT05055830Recruiting
Study blood drug levels in critically ill children
This trial measures how the study medicines move through the body and how they affect the child in the Pediatric Cardiac Intensive Care Unit. It may help doctors choose safer and better dosing for critically ill children.
Durham, North CarolinaAges birth–20 years - NCT07823387Recruiting
Bladder pressure changes during dialysis in intensive care patients
This trial aims to see how special dialysis treatment (called CRRT) changes the pressure inside your belly, which might help doctors make better treatment decisions. If you are in the intensive care unit and need this treatment, your participation could improve care for future patients with similar needs.
Bursa, BursaAges 18 years+ - NCT05450185Recruiting
Test filter lifespan during continuous kidney dialysis
This study looks at whether the lifespan (how long they can be used) of dialysis filters can be optimized during continuous kidney dialysis for very sick adults. If successful, it may improve care and use of dialysis supplies for people with dialysis-dependent kidney injury.
InnsbruckAges 18 years+ - NCT06651879Recruiting
Ultrasound airway check in severe preeclampsia patients for C-section
This study compares two ways of using ultrasound to look at the airway in women with severe preeclampsia who need a C-section under general anesthesia. It aims to find which technique is better, so doctors can prepare more safely for your breathing tube placement.
Cairo, Cairo GovernorateAges Any age - NCT07149246Recruiting
Nutrition plan by a dietitian for ICU recovery
This study tests whether a personalized nutrition plan from a dietitian for 6 months can help people who have been seriously ill in the ICU recover better. It focuses on patients who had organ failure and who live in Norway.
TromsøAges 18 years+ - NCT07820319Recruiting
A new heart ultrasound test for intensive care patients
This study tests a new way to measure heart pressure using an ultrasound, which may help doctors decide how to treat patients in intensive care. If successful, it could be used more widely in the future.
Hong KongAges 18 years+ - NCT04033224Recruiting
Blood-filter treatments for ICU patients with kidney and organ failure
This trial tests a specific type of blood-filter treatment in critically ill ICU patients who have acute kidney injury and/or failure of other organs. It aims to see whether these filters can improve care by supporting kidney function and/or calming harmful inflammation.
Empoli, FirenzeAges Any age - NCT06825377Recruiting
Comparing high-protein vs. standard nutrition for ICU patients
This trial tests whether a high-protein diet or standard protein diet is better for critically ill patients who are at risk for refeeding syndrome (dangerous shifts in fluids and minerals when starting nutrition after starvation). The goal is to see which type of nutrition helps recovery.
TehranAges 18–65 - NCT07310667Enrolling by invitation
Frailty and muscle thickness in older ICU patients
This study looks at how frailty relates to muscle thickness in the thigh for patients over 65 who stay in the intensive care unit for at least a week. It aims to find ways to better support recovery.
Altındağ, AnkaraAges 65 years+ - NCT06737614Recruiting
Blood pressure and heart function in ICU patients
This study looks at the relationship between blood pressure and the amount of blood the heart pumps in critically ill patients. It may help doctors better understand and manage your condition in the ICU.
São PauloAges 18 years+ - NCT07313956Enrolling by invitation
Breathing machine method study in the ICU
This study looks at how different settings on the breathing machine (ventilator) are used for critically ill adults in the ICU. It may help doctors improve care for people who need a breathing tube.
Chicago, IllinoisAges 18 years+ - NCT07256340Recruiting
