Posted June 21, 20168 yr I am curious. Do you lock your central venous catheters which are not in use? How often do you change the lock?
June 21, 20168 yr @fcardona my answer is simple - we don't use locks for central ven catheters, we keep infusions going (at least 1 ml/h) until we take them out.
June 21, 20168 yr We also run our central venous caths at min of 1ml/hr. We recently locked one side of a double lumen venous cath (as a physician preference), & found that it clotted even with regular flushes.Â
June 22, 20168 yr I agree. No locks for CVCs. However, we have been able to keep them from clotting with saline at 0.8cc/h in very tiny babies in whom we really need to watch fluid intakes.
June 22, 20168 yr @gayle omansky @livesynapse Do you add heparin to your infusion solution (used at 0.8 /1.0 ml/h)? The "Stockholm tradition" has been: hospitals on the northern side adds heparin, whereas those on the south side don't use heparin. I changed employer in 2014 and is now with a non-heparin NICU Since I came from a pro-heparin hospital I was a bit skeptical about not adding heparin to our low-flow saline in central catheters/lines. But, it seems to work equally well.
June 22, 20168 yr Author If we continue with low rate infusion, we add heparin to the infusion solution 2 IE/kg/h. I am not really sure that makes sense.
June 22, 20168 yr Our unit does not lock our CVL or PICC's. We run heparinized saline at 1.0ml/hr to keep them patent or we remove them as soon as they are longer needed.
June 23, 20168 yr No heparin. Just saline and, as long as the infusion keeps going, they don't clog. We also remove them asap.
July 5, 20168 yr We also do not use heparin or locks but run an infusion at 1ml/hr. Â If not required we remove the line ASAP

August 5, 20168 yr Hi Stephan, We still add Heparin to all our central line infusions at 0.5u/ml. This is a very interesting discussion & we may need to reconsider our practice. Thanks!
