RE: L-cysteine vs HCL

[Resler, Rosemary]

We use 2 ml (adults) or 110% catheter-fill volume for peds (max of 2 mls) of 50 mg/ml Cysteine Hydrochloride for calcium - phos precipitate or etoposide or for drugs solubilized at a lower pH (e.g., vanc, amikacin, piperacillin). I have used it and it successfully cleared the CVC.

I've heard about cysteine being more readily available in hospitals with large pediatric units.  Apparently it's very acidic.

It's not so readily available in hospitals with adult only populations as in my hospital.

Hello all~

 

We are updating our work instructions/ policies for iv therapy within our institution. Our pharmacy has suggested that we use L-cysteine as opposed to hydrochloric acid for line precipitate occlusions. Any evidence out there to support this change in the way of studies, etc. Anyone out there with a policy they would be willing to share with me? Any and all input is always appreciated. Thanks in advance.
