2. What is CVAD?
• A central venous access

25. PROCEDURE FOR SITE CARE AND DRESSING CHANGE

1. Wash Hands
2. Assemble equipment

28. CATHETER FLUSHING
Vascular Access Devices
shall be flushed at
established intervals to
promote and maintain
patency and prevent the
mixing of incompatible
medications and
solutions.
(Infusion Nursing Standards of Practice:INS, 2006)

29. How often?

30. CATHETER FLUSHING
 The flushing volume should at least be twice the internal volume of
the CVAD and injection cap.
 Preservative-free 0.9% NaCl flushing solutions shuld be used to
ensure and maintain patency of CVADs at established intervals.
 0.9% NaCl with preservatives should not be administered to
neonates and pediatric patients; if used with adult patients, the
volume should not exceed more than 30mL per day
 Flushing with a heparin solution should occur to ensure and
maintain patency of CVADs at established intervals.

31. CATHETER LOCKING
 For intermittently used CVADs, (INS) 2008 recommends”locking”
with owconcentraion heparin as follows:
CVAD Heparin Lock
Recommendations
PICC and Nontunneled Daily with 5mL (10units/mL)
Tunneled Twice Weekly with 5mL
(10units/mL)
Implanted Port Monthly with 3 to 5mL
(100units/mL)

33. Heparin or Preservative-free 0.9 NaCl?
The move to use preservative-free 0.9%NaCl results from
concern over heparin supporting microbial growth, periodic
heparin supply Issues, And use of positive/neutral Pressure
injection caps valves.
