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. .Source: my mom's a nurse.
Love your mum - she is absolutely spot on. I had a CoVID antibody blood test last summer and I didn't feel anything at all with the butterfly needle - it was like magic!
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.
This is until you get into french sizes- for example a 14 Fr. is bigger than a 14g. In medicine, French takes over after gauge stops- Theoretically, after a 1G the next bigger size is 1 Fr with 2 Fr being bigger than 1 Fr. etc. The Fr. sizes usually denote large catheters such as urinary catheters, chest tubes, etc.
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 ?
The gauge refers only to the calibre, or bore, of the needle/cannula. The length of the needles/cannulae can vary, dependent on the length different manufacturers decide to output; also sometimes the same manufacturer may offer needles/cannulae of a specific gauge (e.g. 18) but in differing length options, to suit different clinical needs. Hope this helps.
We select the gauge based upon the nature of the fluid we are injecting or withdrawing. Generally, we need larger gauges when dealing with viscious fluids such as an antibiotic suspension or drawing/infusing blood, and we can opt for smaller gauges when we're working with "thin" more water-like solutions such as vaccines, normal saline, and most drugs. When drawing blood we try not to go any smaller than a 22G needle, because going smaller causes a risk of hemolizing the sample giving inaccurate lab results and perhaps yeilding a sample the lab can't even use. We select needle length based upon the route of administration (IV, IM, or SC). in the case of SC injection, we only need a short needle because injecting into subcutaneous tissue doesn't require that deep of a needle insertion, as compared to injecting into a muscle, where we need a longer needle. It also depends upon patient characteristics and specific site- I might only need a 1-inch needle to inject IM into a lean patient but i might need a 1 1/2 inch needle to inject IM into an obese patient to get through the "extra" subcutaneous tissue and into the muscle. By contrast, IV needles are usually 3/4 to 1 inch depending upon the nature of whether you're inserting an IV line, drawing blood, giving a bolus injection, etc.
There are cannulae with odd-numbered guages. A cannula is a hollow tube, so a hollow needle is essentially a cannula. One can get 25G and 27G needles.🙏🏽
Kenath Warnarathne it’s basically the hollow inside of the needle. Higher number gauge is smaller in its diameter on the inside and thus slower. Smaller gauge has larger diameter. Basically higher gauge is lower flow so used for more precise and small volumes. Lower gauge can allow more to pass thru. Better for blood donation. Or anytime u need to move fluids faster smaller gauge. Has zero to do with the length of the needle.
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
He man people who lack medical training can really hurt themselves when self injecting. There are even stories of people SNAPPING needles inside of themselves and not being able to get it out. Smaller needles usually hurt a little les son entry but can take longer to draw hence increasing the amount of time the damn thin is inside you.

I love the teaching continues

Great video sir. Very informative. 🙏
At 22 you are young enough to be anything you want!
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 ?
Lycanroc i became a nurse at 32, now i am 34. u r too young to worry. u can start now
I’m 30 with four children and a husband. I’m currently finishing up nursing school. There’s no reason you can’t do it to
@@Theuntamedwiz how long nursing is not it 5 years of school or college
Alot of thanks Sir .
Wish u Good luck for more succes ............
You are most welcome
Hey I have a question
Do the 18 gauge needle come standard in length, or you can pick a specific length that you want ?
The gauge refers only to the calibre, or bore, of the needle/cannula. The length of the needles/cannulae can vary, dependent on the length different manufacturers decide to output; also sometimes the same manufacturer may offer needles/cannulae of a specific gauge (e.g. 18) but in differing length options, to suit different clinical needs.

So what is cannula and what is infusion please explain cannula
I do not think this video is for you
May I know why the cannula gauge is all in EVEN numbers ? 🤔
There are cannulae with odd-numbered guages. A cannula is a hollow tube, so a hollow needle is essentially a cannula. One can get 25G and 27G needles.🙏🏽
helped so much thank you
What is the cap thing above it
It’s a cap; to prevent blood leaking back when you cannulate
thanks
Pl explain what the " Guage of a needle." With a diagram
I'm from sri lanka

@@Jsteeeez thanks

😞
sometimes the pain is caused by what is being administered
Dear sir what size needle is less painful in back side.i want to inject my self
Any injection is painful; the smaller the needle, the less the pain. WHY are you injecting yourself?!
He man people who lack medical training can really hurt themselves when self injecting. There are even stories of people SNAPPING needles inside of themselves and not being able to get it out. Smaller needles usually hurt a little les son entry but can take longer to draw hence increasing the amount of time the damn thin is inside you.
Dear sanjib ji can i use 23mm needle in my back side injection
