Blocked catheters and lines

NICE/Cochrane Review

 Heparin versus 0.9% sodium chloride intermittent flushing for prevention of occlusion in central venous catheters in adults, Sept 2015

  • Conclusion: there is no good evidence that flushing with heparin is better than saline.

Caution: There have been a number of instances where inappropriate strengths of heparin have been used as flush solutions.
