After each use, the central venous catheter lumen will be flushed with 10 ml 0.9% NaCl and then locked with heparin 5000 IU/ml(standard treatment)using a volume exactly equivalent to the internal volume noted on each catheter.

Patients with a hematological malignancy who are undergoing intensive chemotherapy need a central venous catheter (CVC)during their treatment. CVCs are locked with heparin when they are not used.

The purpose of this study is to determine whether concentrated citrate locking, compared to heparin, reduces the incidence of central venous catheter-related thrombosis and infections in patients with hematological malignancies undergoing intensive chemotherapy.

Central venous catheter (CVC)-related thrombosis and infections are frequently occurring complications and may cause significant morbidity in patients with hematological malignancies. Interventions to decrease fibrin deposition have the potential to reduce CVC-related thrombosis and infections.

At present heparin is most often used as locking solution for central venous catheters in hematological patients despite a lack of evidence regarding the efficacy and safety. Trisodium citrate (TSC) had been shown to be an effective antimicrobial catheter locking in hemodialysis patients.

Concentrated Citrate Locking to Reduce the Incidence of CVC-related Complications in Hematological Patients

Concentrated Citrate Locking to Reduce the Incidence of Central Venous Catheter-related Infections and Thrombosis: a Randomized Phase III Study in a Hematological Patient Population

Patients will be followed from insertion of the central venous catheter till removal of the central venous catheter, an expected average of 30 days. The central venous catheter is seen daily and checked for thrombosis and infections when the patient is admitted on the ward. Discharged patients are seen at least weekly on the outpatients clinic and their central venous catheter is checked for thrombosis and infections. A standard ultrasound is made 30 days after insertion and within 24 hours after removal of the central venous catheter.
