Heparin or saline for flushing CVADs?

A Cochrane review found no conclusive evidence of important differences when heparin intermittent flushing was compared with 0.9% normal saline flushing for central venous catheter maintenance in terms of efficacy or safety. As heparin is more expensive than normal saline, these findings challenge its continued use in CVC flushing outside the context of clinical trials.

Heparin or saline for flushing pediatric CVADs?

Another Cochrane review found that there was not enough evidence to determine the effects of intermittent flushing of heparin versus normal saline to prevent occlusion in long term central venous catheters in infants and children. Ultimately, if this evidence were available, the development of evidenced-based clinical practice guidelines and consistency of practice would be facilitated.
