This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study will check if two blood markers (MPV and PDW) can help doctors find deep vein thrombosis early in ICU patients who need a breathing machine. Researchers will follow 100 adults in the ICU and use ultrasound to confirm any clots. The goal is to see if these simple tests can predict clots and help guide treatment.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

he population will consist of mechanically ventilated ICU patients, a group at particularly high risk of thrombotic events due to immobility, systemic inflammation, and sedation, which limit symptom reporting. Eligible participants must be adults (\>18 years) who remain intubated for ≥48 hours. Patients with confounding conditions such as hematological malignancies, congenital platelet disorders, recent platelet transfusions, pre-existing DVT, anticoagulation therapy prior to ICU admission, or pregnancy will be excluded. This selection creates a homogeneous population highly vulnerable to DVT, ideal for assessing the predictive value of MPV and PDW.
