Continuous Heparin Infusion to Prevent Catheter-related Thrombosis

Status Completed

Clinical Trial Summary

Clinical Trial Description

Catheter-related thrombosis could impair blood flow in the vein, block the central venous catheter, induce catheter-related infection or venous thromboembolism in the deep veins or pulmonary vessels, which furthermore progress into the post-thrombotic syndrome. Researches using echogenic mass as the primary outcome could miss those premature thrombi which might not be seen on traditional ultrasonography but may be detected by Duplex and Doppler ultrasound with vessel compression. Moreover, studies indicated that some thrombus developed after the catheter removal. Removal of the catheter is not the endpoint of thrombus detection. This study is designed to determine the preventive effects of continuous heparin infusion on real-world central venous catheter-related thrombosis in infants after cardiac surgery. One hundred and twenty-four infants were randomized to the intervention group or the control group. Unfractionated heparin or normal saline was infused continuously through each lumen of the central venous catheter at the speed of 0.5 ml/h/line until the catheter was removed. Catheter-related thrombosis was detected by point-of-care Duplex and Doppler ultrasound periodically until 30 days after the cardiac surgery or discharge, whichever comes first. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
