I had a PICC line twice and each time was different. I was told it came down to what your insurance will pay for.
The first time I had what Josephine just shared and what
@dinsmaum used. The sphere balls were filled with the antibiotics. The first time, I used Piperacillin/Tazobactam brand name Zosyn. You would attached it onto your picc line and as
@dinsmaum explained, it would get sucked up through the line until completed. It took about 10 mins. if I remember correctly. The down side was it had to be done 3X a day at precisely 8 hour intervals. My nurse was strict about this so I did as I was told.
This was before the spacer went in. I first had only a debridement in hopes that I could kick out the bacteria on my own. In hindsight by all, it was wishful thinking as it did come back. So after this surgery, I was feeling fine and was in no pain. When we would go somewhere for the day, I had to find discreet areas to administer my “drug”! I felt like a drug addict in plain view!

It became a funny joke in my family.
The second time I had a much better system. I used a simple injectable syringe once a day. That was it! The antibiotic was Daptomycin, brand name Cubicin. My insurance changed and my nurse said this was a good thing, so much easier!
The package with all the necessary equipment would be delivered once a week at which time the antibiotics had to be refrigerated immediately. The nurse came once a week to clean and change the tubing. I was able to shower without a problem. The tape they used was pretty airtight so I never had a problem with that.
@KarriB, I would love to see what your’s looked like.

At least it was only once a day! I know you just retired but how does it feel to know you do not have to go back in September? Hope you are doing well.
@McDeeva, How are you doing? I suspect you have your PICC line installed by now. You have a lot of help here so please let us know what your next step will be so we can help you through it.
@Josephine, hope this helps give you and others further insight on the PICC line. Especially the last one I had. Makes it so easy for the patients.
