Closed blood sampling devices for adult ICU patients

Official title: Effectiveness of Closed-blood Sampling Devices in the Adult Critically Ill Patient: Multicenter Randomized Clinical Trial

Run by University of Barcelona · NCT06478160 · Data updated 2026-11-12

We will try closed‑blood sampling devices to see if they reduce the amount of blood taken for lab tests and lower the need for red‑blood‑cell transfusions in adults in the ICU who have arterial catheters.

Is this trial a fit for you?

Likely a good fit

Adult ICU patients with an arterial catheter who have been in the unit for 24 hours and are expected to retain the catheter for at least 72 more hours, who meet inclusion criteria and consent, are eligible.

Probably not a fit

Patients with chronic renal failure, active gastrointestinal bleeding, hematologic malignancies, women menstruating at admission, pregnant women, Jehovah's Witnesses, or those who develop active GI bleeding during the study are excluded or unlikely to benefit.

What this trial studies

Adults with an arterial catheter who have been in the ICU 24 hours and are expected to keep the catheter for at least 72 more hours are randomized to either a closed‑blood sampling device (CBSD) or the usual open sampling with waste discard volume. In the CBSD group the device is attached and all arterial samples are drawn through it; in the control group the ICU's standard open extraction system is used and the discard volume is recorded. Investigators record the volume of blood drawn for laboratory tests, red blood cell transfusions, and arterial catheter‑related adverse events daily during ICU stay for up to 21 days or until discharge or death. Patients discharged to the ward are followed for 48 hours to capture any transfusions after ICU transfer.

Why it matters

Potential benefit: If successful, this approach could reduce diagnostic blood loss, lower the number of red‑cell transfusions, and possibly decrease catheter‑related complications for ICU patients.

How similar studies have gone: Previous studies of closed blood‑sampling devices have generally shown reduced diagnostic blood loss and, in some cases, fewer transfusions, though results vary and evidence is not uniformly definitive.
