Why do some people pull blood into a syringe before injecting?
to make sure they are in the vein.
How does skin look after being injected with a syringe?
You get a small dot sometimes you can't even see it, sometimes you may get some redness around the edges, should usually go away quite quickly as it's the same as a little scratch, but sometimes your arm can swell if you have an allergic reaction or an infection in which case you need to go to the doctor. if it's into your veins you can get a really nasty looking bruise which can last a few weeks (usually after you've had blood taken). I really would suggest an amateur inject you especially if it's near your veins, in fact, why would an amateur be injecting you in the first place? :/ If they know what they're doing you should just get a bruise at the worst, if they don't have a clue, don't let them near your arms hun, the last thing you want is an infection in your blood as it can be dangerous and even fatal
When blood is in a syringe mixed with meth, how can you tell when you pull back and you have it in the vein?
Well when your attempting to register a shot that already flashed blood in your needle…you can still pull back the plunger and wait for blood to rush in. The blood mixed in with the dope may make it a little cloudy but just Watch it and if it's a clean shot you should be able to see the blood enter the needle and register.
Why do my veins not fill the syringe with blood when injecting meth?
First of all obviously you should not be doing meth, but you definitely don't need to be trying to inject it if you don't know what you are doing. You are probably not even sticking the needle into the actual vein, if you were then you should be getting a blood return. When you are injecting ANYTHING into your arm and you don't know what you are doing (especially if you are high and trying to do it) then you run the risk of causing an infection, cellulitis, abscess, sepsis, etc. You increase all these risks if you are using a dirty or contaminated needle, not to mention if you ever share needles you are opening yourself up to HIV and all forms of Hepatitis, etc. I have seen people lose their limbs and also parts of them from serious infections and sepsis, gangrene, necrotizing fasciitis, etc. It is not pretty and it smells literally like death or worse. Just FYI it is easier than you might think to set up an infection especially if your immune system is already compromised from drugs.
What would happen if you injected a syringe full of water into your arm?
A couple of things :You would get a bump, depending on how much water you injected. The most common syringe would be one for insulin and allergy shots, and it holds .5cc, which is more than enough to cause a noticeable bump. But there are larger ones (10cc and up), and those could actually cause injury to something if you aren’t careful where you inject. And it may hurt like heck.If you were unlucky, you would inject the water into a vein or artery (vein is worse). This could cause thinning of the blood until it got mixed in, and so affect oxygen/carbon dioxide exchange. I doubt it would have a huge effect, but for a short period of time, it would have an effect.If you were REALLY unlucky (and didn’t use sterile water, and make sure the needle was clean, and use an alcohol swab on the injection site), you could get an infection. Specifically with the non-sterile water, an infection inside a muscle can be a really bad thing, leading to septicemia (blood infection) and death.
Reusing Needles for Blood Draw?
Hello I recently went to a medical lab and they drew some blood from me for some tests. The thing that is worrying me is that I wasnt paying attention to the nurse when she got the needle so I dont know if she used a new or reused an old needle by mistake/ My question is, can these needles be reused or are they designed for one time use only?? I am afraid of contracting any blood disease from this incident
Venipuncture with a syringe and needle?
the standard size needle for blood draw in the laboratory is 21 gauge. with practice you learn to stop when you see a flash at the hub of the needle. eventually you can tell by feel when you are in a vein. as a rule 25 gauge needles are too small to draw blood.. it will cause the blood to be hemolyzed and the specimen will have to be recollected. occasionally the lab does use 23 gauge needles for really small veins. butterflies are the same size gauge as regular needles (21g and 23g) the only difference is that the butterflies are shorter..3/4 of an inch rather than 1 inch or 1 1/2. since they look smaller psychologically the patient thinks you are using a smaller needle. on very rare occasions I have used a 25 gauge on a neonate with extemely small veins but it takes extreme care get an acceptable specimen.
Why would white worm-like substances be in a syringe along with clots after pulling blood back?
In my opinion, the white worm-like substance sounds like they could be fibrin strands. You said there were clots alongside, so it would make sense. Trauma during the venipuncture can cause the fibrin strands. So what you are seeing is essentially the beginnings of a clot, without the trapped red cells that make a clot red.In addition, we see them in tubes that were not anti-coagulated, not inverted properly, or were over-filled. We cancel and ask for a redraw, as results are affected, and they can clog the analyzers.Edit: I found a photo of what a fibrin clot looks like:. It can be hard to spot in gold tops because it almost looks like the separator gel.https://www.dshs.texas.gov/asset...
