The nurses in the post-partum unit want to use heparin flush on peripheral IVs because of the hypercoagulability.  Does anyone else do this?  We just use NS on the other units including the oncology unit.

I cannot find any evidence

I cannot find any evidence based research to advocate using heparin in peripheral IV sites on OB patients.  I would really appreciate it if anyone else uses heparin on their lines would give me the rationale.  I don't want to expose these patients to heparin if it is not necessary.
