Life tip; if you have anxieties or phobia on needles, when you get your blood tested request for the "butterfly" needle, it has a very fine tip that you can barely notice when it punctures the skin, commonly used in pediatric patients AKA children/babies.

The “guage” refers to the diameter of a pipe and a cannula is essentially a small pipe. Somewhat confusingly however, for IV cannulas, the larger the number of the gauge, the smaller the size. So, a 25guage IV cannula is smaller than a 20guage cannula, which in turn is smaller than a 18gauage cannula. Hope this helps.

I had surgery twice. The first is for my appendectomy, and my appendix had ruptured without me knowing as I have relatively high tolerance for pain (running on 4th day before I decided to see the doctor). The nights leading to that, I was having difficulty sleeping (1st night, waking every after 3 hours, then the following night every 2 hours, then the third night every hour). When I was on the operating table and the spinal anesthesia was administered, all the discomfort I endured went away, and I just fell asleep. When I opened my eyes I was already in the recovery room.

The 2nd surgery years later was for my choledocystectomy. This time I was administered general anesthesia. That really hurt as it was being administered, like your nerves were being pulled out as the anesthesia spread from my IV cannula to my hand, then lower arm, upper arm, shoulder, then after that I was knocked out. I woke up at the recovery room with the tube still in my throat.

These videos are so informative and interesting. I would love to become a nurse one day but I am already 22 years old... do you think I am already to old to become a nurse ?

I was never the person that is afraid of needles, since I'm not exposed to it often. I only learned of its pain when I took my Covid vaccine and hell it was damn painful

[no-delg]

So what is cannula and what is infusion please explain cannula

[michellim]

May I know why the cannula gauge is all in EVEN numbers ? 🤔

[SaraRuss-gbsg]

Hey I have a question
Do the 18 gauge needle come standard in length, or you can pick a specific length that you want ?
