ethanol lock

Can anyone give me information on using an Ethanol lock on a central line?  It is really strange, but I heard of a pt in the hospital just now at nutritional support meeting, and coming back to the office after that meeting, I had a Home Care RN ask me about the same thing on a patient of hers!!!  I have (a number of years ago) used it for lipid sludge in a Hickman, but have not yet heard of using it as a lock.  In the 2nd case, the MD wants to use it daily as a lock solution AFTER the patients antibiotic therapy iis completed.

In the first case the doc is using it because this is the pts last place for a central line and the doc is trying to keep the line.  That is what the pt told the pharmacist.

Anything you can share will be appreciated.  Thanks!!

This is becoming more common

This is becoming more common in practice. There are several articles published about its use as a lock solution. However it is not available as a commercial product in the US in a prefilled syringe or even with a labeled indication for locking catheters. You will need to get this from a compounding pharmacy in a sterile solution. Lynn

Thanks Lynn.  Yes, our

Thanks Lynn.  Yes, our pharmacy made it years past, so they would probably do this.  Do you have references to the articles?

Thanks so much for all your help!!

Ethanol references

We've used ethanol 70% locks for a few high risk home parenteral nutrition clients for a few years now successfully. The clients instill the ethanol, using the prefilled syringe, in the am after flushing the catheter with NS upon completion of the night PN. The solution is left indwelling for ~ 12 hrs and is then either flushed through or aspirated from the catheter before hooking up the next night. You'll need to confirm with the manufacturer that the catheter material is compatible with the solution. Here's a list of references (sorry I tried, unsuccessfully, to post it as an attachment).
