Clinical Trial Summary

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.


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.

Intervention

Drug:
Heparin sodium
For infants without thrombosis at enrollment, heparin 1 U/kg/h/line for term infants was used and 0.5 U/kg/h/line for preterm infants. The speed of infusion was 0.5ml/h. For infants with thrombosis at enrollment, heparin 10-15 U/kg/h for term infants was used with a target activated partial thromboplastin time 60-70s. Other interventions were at the clinical team's discretion under the local protocol.
Normal saline
For infants enrolled, normal saline was infused at the corresponding speed.

Outcome

Type Measure Description Time frame Safety issue
Other Post-thrombotic syndrome The symptoms of post-thrombotic syndrome included aching, swelling, itchy and ulcer in the indwelling site and the collateral varicose veins. 6 months after cardiac surgery
Primary 124 infants of CVC-related thrombosis by point-of-care echography or ultrasound CVC-related thrombosis of any catheter as imaged by echocardiogram or ultrasound at 30 days after cardiac surgery. Thrombus was defined as an echogenic mass near the tip of the catheter or slow/no flow detected by Duplex and Doppler ultrasound at the nearby vessels and the on-site vessel couldn't be clasped as narrow as the collateral vessel by compression of the probe. 30 days after cardiac surgery or at discharge, whichever comes first
Secondary 124 infants of heparin-related comorbidity Abnormal coagulation and hemostasis were defined as treatment initiation by the clinical teams at the discretion of heparin adverse events. Heparin-induced thrombocytopenia was confirmed with consistent low platelet level and positive enzyme-linked immunosorbent assay heparin-platelet factor 4 antibody assay. Catheter-related sepsis was defined as culture of the same organism from both the catheter tip and at least one percutaneous blood culture. Culture of the same organism from the catheter was also accepted as an alternative of culture of catheter tip. 30 days after cardiac surgery or at discharge, whichever comes first
