Collecting Blood Samples with a Butterfly Needle and Vacutainer Tubes

- Collecting Blood samples for labs is something that is done by phlebotomists, RNs, and PCTs. This video explains and demonstrates the use of the supplies available at Trinity Health Livonia, and the process to follow to safely and effectively draw blood samples from a patient.
This is the best instructional video I have seen for blood draw. Thank you!
Thank you. I take pride in my content. I'm glad you found it helpful.
I wish videos could be done on patients that have hard veins, extremely crepey skin, no muscle tone, rolling and sclerosed veins from drug use. The reality of drawing blood is so different from these training videos.
yeah, the legality of that is touchy, so I stick to the manikins in most cases unless I use myself or a friend. The thing about difficult venipuncture is that the best way to get better is to keep trying. I look at the videos as a way to get the groundwork in and give you what you need to start trying. once you get some confidence under your belt the trial and error phase is where the real learning comes in.
@@nursingeducation3952 Yes, I get that. However, I have had nurses tell me they will do it when I miss the vein and I refuse to dig around. Funny thing is those nurses didn't get the vein either. One nurses was an absolute disaster and I had to tell her to leave. My biggest concern for my draws is making sure I have good samples and of course the correct patient!
Doesn't the order of draw differs with butterfly. Shouldn't there be a tube for air or something like that?
At my facility the only time there is a difference if order is if you are pulling labs from an existing line such as a picc, central, midline, or IV. If that is the case, you first have to draw a waste tube before drawing into the actual lab tubes. If we are drawing with a butterfly, the waste is not neccessary. But your point about clearing air does make sense, you're limiting the amount of blood that gets into that tube because the air will get in first. I believe the vaccutainers probably account for this though and it doesn't have enough of an impact to ruin a sample. In practice, I have never had an issue with my samples related to air in the line.
ONLY when drawing a light blue top first. And then it's recommended that the discard tube is another Lt blue top. With blood cultures, if ordered, they are drawn first, and the Aerobic bottle is drawn before the anaerobic bottle to prevent air from entering the Anaerobic bottle.
Is there a authorized distributor here in the philippines where is it located
Sorry, i don’t have any info for that. I am in no way connected to any product companies. Only concerned with the safe utilization of the products themselves.
Curious, I had a blood draw where they put the vac tube connected to the butterfly needle prior to insertion. I feel like he already broke the vacuum seal prior to inserting as I did not hear the normal pop is dangerous for the patient?
I guess what I’m asking is a possible for air to exit the vacuum tube and enter bloodstream if the vacuum tube is connected to butterfly needle prior to insertion
If they broke the seal it wouldn’t have pulled any blood. So if it was a successful draw they likely set it in the adapter and once they got access pushed it onto the needle and got the blood. That’s pretty common practice from what I’ve seen others do.
Is it wrong to pull the needle out with the last tube still inside the adapter? This way the remaining blood can be absorbed into the tube. Does this create contamination or is this ok?
When the tube stops filling with blood, the pressure inside the tube has equaled the pressure outside, so it won’t actively pull anymore blood into the tube. You shouldn’t remove the needle until that tube has filled to its capacity anyway, so removing the needle while the tube is attached won’t pull the remaining blood from the line into the tube. I don’t see any particular contamination risk to having the tube in the adapter when you remove the needle, but there is not benefit.
I work with pediatric patients so it’s very hard to get the tube to fill up even half way, so what we end up doing is pulling out the needle while the tube is inside the adaptase to get the remaining blood allowing the tube to be filled enough for lab. So you are confirming this is not a contamination right? I had to argue with a few colleagues because of this
@@halaa9319 I can’t say yes or no for sure, but I wouldn’t think so. What are you concerned about contaminating with? Air? And what are you drawing for? CBC, CMP, etc? I don’t see how exposure to room air would have any kind of impact on a lab like this. If it were a blood culture…sure I can see a better argument against it.
Hi! may I use the video for my phelebotomy lecture demo please?
Absolutely.
Don't. They close it wrong.
Can you use this for blood letting without the vacum glasses? So just the butterfy needle?
I've never seen it used for that. When I've done blood letting it has been with a specific needle/drainage bag system. The gauge was (I think) 18. The general gauge of a butterfly is a 21, which is technically large enough for blood, but wont allow for the flow rate you could have with an 18. My final though would be that you would need a drainage container or bag that has an adapter for the end of the butterfly. It needs to uncover that rubber tip from the needle on the end, and you would want to solidly attach to the needle so it wouldn't risk coming apart. The end of the buttefly tubing is threaded to attach the vacutainer adapter piece.
@@nursingeducation3952 damn…. I want to donate blood more often because my ferritin is crzy high. But im limited to once every 4 months -.- i will try with just the butterfly and see if it works if not then idk.
Thanks alot for the reply
Blood donations ARE done with butterfly needles often, but they are larger gauge than this.
@@nursingeducation3952You are wrong. A Green butterfly is 21 g. The most commonly used butterfly is a 23g.
