Feasibility and Safety of Targeting Neutral vs Liberal Fluid Balance in Traumatic Brain Injured Patients- LIMIT-TBI Trial
Belgium, Italy88 participantsStarted 2025-07-01
Plain-language summary
The LIMIT-TBI trial is a multicenter, international, randomized, phase II clinical trial designed to evaluate the feasibility and safety of targeting a neutral fluid balance compared to standard care in critically ill adult patients with traumatic brain injury (TBI).
Fluid therapy is a cornerstone of TBI management, but optimal fluid balance remains uncertain, with both fluid overload and restriction potentially leading to adverse outcomes. This study aims to determine whether maintaining a daily fluid balance close to zero (±500 mL) during the first 5 days of ICU admission is achievable and safe.
Participants will be randomized within 48 hours of ICU admission to either a protocolized neutral fluid balance strategy or standard care. Outcomes include feasibility of achieving the target balance, organ complications, hemodynamic parameters, ICU resource utilization, and mortality and neurological outcomes up to 6 months.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult patients with traumatic brain injury (isolated or associated with extracranial injuries), with or without intracranial pressure monitoring
* Admission to the intensive care unit
* Age \>18 years
* Enrollment within 48 hours after ICU admission
Exclusion Criteria:
* Enrollment in another clinical trial not approved for co-enrollment
* Pregnancy or suspected pregnancy
* Concomitant hemorrhagic shock expected to require surgical treatment within 24 hours from inclusion or requiring massive transfusion protocol
* Hemodynamic instability at ICU admission, defined as heart rate \>120 beats/min and systolic arterial pressure \<100 mmHg despite at least 1 L of fluid resuscitation, or requirement for high-dose norepinephrine (\>0.5 mcg/kg/min) or any inotropic support
* Need for continuous venovenous hemodiafiltration (CVVHDF) at admission
* Expected survival \<48 hours
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
