The patient is treated with anticoagulants
Absence of obvious signs of infection at the catheter insertion site (discharge, redness, and swelling)
Place the catheter in the subclavian or internal jugular vein
The activated partial thromboplastin time (PTT) is within the normal range
Less than 24 hours have passed since the central venous catheter was inserted

Primary Outcome Measures

Name	Time	Method
The duration of the opening of the central venous catheter. Timepoint: The primary outcome (catheter patency) is checked every 8 hours. The length of time the catheter remains is recorded at the end of the study or when the catheter is blocked. Method of measurement: How to set the duration of the central venous catheter open is the clock.

Secondary Outcome Measures
