How different ways of drawing blood from a central line compare for heparin activity
Part of Blood & lymphatic, Heart & circulation clinical trials.
This trial checks whether blood samples taken from a central line using either a syringe flush or a vacuum tube give the same heparin activity results as blood from a vein in the arm. It is designed for patients in the ICU who are on a steady heparin drip.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older
- You are currently in the intensive care unit (ICU)
- You have a central line (a special IV placed in a large vein in the neck, chest, or groin) with at least three ports
- You are receiving a continuous heparin drip, and your target Anti-Xa level (a test for blood thinning) is between 0.3 and 0.7 IU/ml
- You are able to give consent or have someone do it for you

This study compares two ways of measuring how well the blood thinner heparin works in children after heart surgery in the ICU. The goal is to find the best method to keep the dose safe and effective.
This trial compares using heparin (a blood-thinning medicine) versus saline (salt water) to keep a peripheral IV line open and working. It may help reduce line blockage and improve how well IV treatments can be given.
This trial tests whether giving a blood thinner before placing a central line (a special IV) helps prevent clots in critically ill children. It could lower the risk of problems from the line.
This trial compares two ways of flushing a small chest tube used to drain fluid from around the lung: one uses plain salt water (normal saline), and the other uses a salt water solution that contains a blood thinner (heparin). The goal is to see which method keeps the tube from clogging better.
This study looks at how blood clotting is activated in new central venous catheters (large IVs placed in a chest vein). It may help doctors understand and reduce clotting risks. You can join if you need a new catheter and are not on strong blood thinners.
This trial tests whether starting enoxaparin (a blood-thinner) within 24 hours after placing a specific type of central line can prevent dangerous clots. It may help reduce clot risk in people whose line is placed in the neck or thigh vein, while also tracking bleeding side effects.
