I’ve been using the Silhouette 13 mm infusion set for almost a year now. This set is design for an angled manual insertion and may also be deployed using the spring-loaded Sil-serter inserter. Silhouette is a Medtronic infusion set.
This morning I needed to place a new infusion set and ran into an unusual failure. Let me preface my comment with the note that I’ve experienced a high degree of success with this infusion set. It’s been rock solid for me.
When I inserted this set with my Sil-serter this morning, I had difficulty withdrawing the introducer needle. I needed to used considerable force to pull it out. I was somewhat surprised to see this bent needle when it did come out.
I replaced the site with another one even though I was tempted to leave it in service, thinking that even a bent cannula could deliver service provided it was not kinked. My better judgment prevailed and I’m glad I didn’t try to salvage some value out of this infusion site. Here is what the cannula looked like when I pulled it.
Sorry for the fuzzy focus, I tried my best to make my cell-phone camera reproduce what I could see. While it’s tricky to control the focus, you can see the tortuous angle of the cannula. While it looked like the cannula is not kinked, it’s severe angle change looks like it would have highly increased the chances of a failed site.
The lesson I take from this: if it takes any unusual amount of force to withdraw the introducer needle, it’s best to abandon that site and use a new replacement set.
Anyone else experience something like this?
