Recruiting studies
- NCT05440851Recruiting
Testing different treatments for severe breathing failure in ICU
This platform trial studies which treatment works best for adults with sudden, severe breathing failure needing oxygen or a breathing machine in the ICU. It may help patients by matching them to the most appropriate treatment strategy and tracking outcomes to improve care.
Tucson, ArizonaAges 18 years+ - NCT05443321Enrolling by invitation
Health information sharing during hospital transfers
This trial studies whether sharing patients’ health information between hospitals during transfers can improve outcomes. You may be included if you are moved from a specific partner hospital to Brigham and Women’s Hospital and admitted to certain hospital units.
Boston, MassachusettsAges 18 years+ - NCT05409573Recruiting
Check oxygen monitoring during pre-intubation in the ICU
This study tests whether a specific oxygen level monitor (end-tidal oxygen, or EtO2) can be used during “preoxygenation” before breathing tube placement. It may help clinicians intubate more safely for people who urgently need a breathing tube due to serious breathing failure.
OrléansAges 18 years+ - NCT05298982Enrolling by invitation
Join a long-term follow-up study for ICU care
This study follows people who joined the TEAM Phase III trial to learn how ICU care affects health over the long term. Your participation helps researchers understand outcomes long after the initial treatment.
Camperdown, New South WalesAges 18 years+ - NCT05279547Recruiting
Bed-cycle exercise study to test muscle oxygen during ICU care
This trial tests whether brief “interval” bed-cycling changes how well your leg muscles use oxygen compared with steady cycling. It’s meant for carefully selected ICU patients who can safely do active cycling while on ventilator support.
LeuvenAges 18 years+ - NCT04530760Recruiting
Study of breathing problems in people with liver scarring on a ventilator
This study looks at whether people with cirrhosis who are on a breathing machine have increased pressure in the belly and small unnoticed breathing mist (microaspiration). It may help doctors better monitor and prevent breathing complications while patients are being mechanically ventilated.
LilleAges 18–99 - NCT05218083Recruiting
Mobile rehab program with interval exercise after COVID-19
This trial tests a coach-supported, phone-based rehabilitation program that includes high-intensity interval-style exercise for people recovering from COVID-19 after a hospital stay. It may help improve breathing, strength, and walking by providing structured exercise at home.
Birmingham, AlabamaAges 18 years+ - NCT05198167Recruiting
HOFA versus hydrocolloid dressings to prevent bedsores
This trial compares two types of skin protection to prevent pressure sores (bedsores) in people who must lie face-down (prone) in the ICU. It may help by reducing new sores from constant pressure in common injury areas.
Majadahonda, MadridAges 18 years+ - NCT05160987Recruiting
Sedation choice for ICU patients on breathing machines
This study compares two sedation medicines—remimazolam vs midazolam—for very sick ICU patients who are on a breathing machine. It looks at whether one sedative works better or is safer for keeping patients comfortable while they’re critically ill.
Guangzhou, GuangdongAges 18–80 - NCT05127265Recruiting
AI and sensors to monitor patients in the ICU
This study uses AI and sensor data to better monitor people while they are in an intensive care unit (ICU). It may help teams notice changes sooner and improve care for ICU patients.
Gainesville, FloridaAges 18 years+ - NCT04955210Recruiting
Study of data sharing in children with severe infections
This trial builds a shared medical data system to better understand severe pneumonia and sepsis in children. Your participation helps clinicians and researchers learn from many cases to improve future care.
Shanghai, Shanghai MunicipalityAges 4 weeks–18 years - NCT04987840Enrolling by invitation
Hospital program to reduce unnecessary lung culture tests in kids
This trial studies a hospital quality-improvement program that aims to use fewer “respiratory culture” tests in pediatric intensive care units (PICUs). It may help reduce unnecessary testing while maintaining good care for critically ill children.
Baltimore, MarylandAges Any age - NCT03753412Recruiting
Rehab program for adults after ICU recovery on ECMO
This trial looks at a recovery and rehabilitation approach for adults who were very sick and needed a machine called ECMO to support breathing and heart function. It may help people regain strength and function after a severe ICU illness.
LondonAges 18 years+ - NCT04265703Recruiting
Ultrasound-guided line placement for hard-to-access veins
This study tests a specific ultrasound-guided technique to place a central venous catheter (a medical access line) when jugular veins are difficult to access. It may help reduce failed attempts and improve safety in people who need this kind of line for medical care.
GuadalajaraAges 18–80 - NCT04201704Recruiting
Less IV fluids for children after trauma
This trial studies whether giving children less fluid through a vein after serious injury helps them recover safely. Children are enrolled soon after arrival to the ICU so the team can compare outcomes between different fluid amounts.
Buffalo, New YorkAges 6 months–15 years - NCT04180397RecruitingPhase 4
Removing extra fluid in critically ill ICU patients with overload
This trial studies a medicine strategy to remove extra fluid from the body in ICU patients who have fluid overload. It aims to see whether controlled fluid removal is safer and better for recovery than usual care.
SydneyAges 18 years+ - NCT04043598Recruiting
Fluids choice after brain bleed to improve brain outcomes
This trial studies whether giving a specific type of IV fluid (a salt-water fluid in the vein) after a type of brain bleed can improve neurological recovery. It focuses on adults with a non-traumatic subarachnoid hemorrhage (a bleeding in the space around the brain) given soon after diagnosis.
Sankt Gallen, Canton of St. GallenAges 16 years+ - NCT04047784Enrolling by invitation
Using EBUS to help diagnose a blood clot in the lungs
This study looks at whether a procedure called EBUS (a camera passed through the airway) can help doctors diagnose an acute pulmonary embolism—a sudden blood clot in the lungs—in critically ill, intubated ICU patients. If you’re eligible, EBUS may be done during bronchoscopy as part of your usual care to help confirm or rule out the diagnosis.
Los Angeles, CaliforniaAges 18 years+ - NCT03419260Recruiting
Continuous EEG monitoring in critically ill children
This study looks at whether continuous brain-wave monitoring can guide seizure care in sick children in the pediatric intensive care unit. It also studies how this approach may affect children’s thinking and behavior later.
Philadelphia, PennsylvaniaAges 1 month–18 years - NCT03451968Recruiting
Amino acid levels in long ICU stays after surgery or trauma
This study measures amino acids (building blocks from food) in people who are critically ill after surgery or trauma while they stay in the ICU for more than a week. It also compares results with healthy adults to better understand how critical illness affects nutrition needs.
Petah TikvaAges 18 years+ - NCT03244293Recruiting
Using a brain monitoring number to grade sepsis severity
This trial tests whether a bedside monitoring number called BIS can help sort sepsis into severity levels. If you have sepsis in the ICU, it may help clinicians track how serious it is and guide care.

Common questions
- Are there clinical trials for critical illness?
- Yes. Clin2 currently lists 333 recruiting critical illness studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a critical illness trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a critical illness trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
