ORIGINAL RESEARCH
Abstract Bloodstream infections related to the use of central venous
catheters are an important cause of patient morbidity, mortality, and
increased health care costs. Catheter-related infection may be due to
fibrin deposition associated with catheters. Interventions designed to
decrease fibrin deposition have the potential to reduce catheter-related
infections. This study was a randomized, controlled trial in which 246
patients with nontunneled central venous catheters were randomly as-
signed to receive a heparin-coated catheter with 50 mL/d of normal sa-
line solution as a continuous infusion (heparin-coated group) or a non-
coated catheter with a continuous infusion of low-dose unfractionated
heparin (control group: continuous infusion of 100 U/kg/d). Catheter-re-
lated bloodstream infection occurred in 2.5% (3/120 catheters) in the
heparin-coated group (0.9 events per 1,000 days) and in 9.1% (11/120
catheters) in the control group (3.5 events per 1,000 days; P = 0.027). No
other risk factors were found for the development of catheter-related
bloodstream infection. Six and seven patients experienced severe bleed-
ing in the heparin-coated and control groups, respectively (P = 1.00). We
did not observe heparin-induced thrombocytopenia. The use of hepa-
rin-coated catheters can be a safe and effective approach to the preven-
tion of catheter-related bloodstream infection in patients with hemato-
oncologic disease.
Methods
STUDY DESIGN
This prospective, randomized, controlled tri-
al was conducted between May 2005 and June
2006 at the National Center for Bone Marrow
Transplantation in Tunis, Tunisia. The study
protocol was approved by the local medical
ethical committee. All patients or their legal
representatives gave written informed consent
before entering the study, which was done in ac-
cordance with the Declaration of Helsinki. This
study is registered at ClinicalTrials.gov, number
NCT00207779.

entral venous lines (CVLs) are com-
monly used in patients with hemato-
oncologic disease for hemodynamic
monitoring, administration of medica-
tion, and parenteral nutrition.

Complications
of catheterization include mechanical (arterial
puncture, pneumothorax), thrombotic, and in-
fectious complications.

Approximately 80,000 central venous cathe-
ter-related bloodstream infections (CRBIs), rep-
resenting 5.3 infections per 1,000 catheter days,
occur annually in intensive care units in the
United States.
7
Attributable mortality for these
infections ranges from 10% to 25%; each CRBI
adds as much as $5,000−$19,000 and 12.5 days
to a hospital stay.

Studies have shown that catheter-related in-
fection may be due to fibrin deposition associated
with catheters.
9–11
Interventions designed to de-
crease fibrin deposition and thrombus formation
have the potential to reduce catheter-related in-
fections. Recently, in a randomized, controlled
study, we showed that a low-dose of unfraction-
ated heparin (UFH; 100 U/kg/d) was a safe and
effective way to prevent CRBI in patients with
hemato-oncologic disease.
