should u only reister once when IVing to see if ya got it in a vein?

[benzos4breakfast]

hey im new to BL just starting out with IVing so Ive been asking a few questions. anyways.
my mate always does it for me.
Anyways he puts the needle in & draws back to see if its in a vein (I think this is called registering?)
anyways when his about half way putting down the plunger he registers again to see if the needle is still in the vein?

Is this the correct way of doing it or should u only check once?

Sometimes he actually does this a few times if there the syringe is almost completely full of liquid.

Ive also heard that it's VERY bad to hit an artery while shooting. just wondering how to avoid this.
I only shoot & will only ever shoot between my arm & forum the opposite side of ya elbow. (the most common place where ppl do it)
Is there any risk of hitting an artery around that area & if so. how can I help avoid doing that?

It's best to do it like that, especially since you are not IVing yourself. It is possible for the needle to slip out of the vein halfway through a shot, so re-registering lets you know you are still in the vein. Normally you can tell if you slip out because it will sting, but since he is IVing you, he can't feel what you feel, so re-registering is his best way of knowing if the needle is still in the vein.

Some people seem to get a bit carried away with this, doing it 10x for one little shot, but I think that doing it 2-3 times for a larger shot is reasonable. It's common practice among IV users, although there are some that will only register once per shot.

It's good to re-register if you're doing a large shot, with a lot of volume.. But like Tommy said, most people can just tell if they feel any kind of burning sensation that they've slipped out. You'll know if you're in an artery if you are registering, but still feel a lot of pain when pushing down on the plunger. Sometimes the pressure will also push the plunger back to you. Sometimes you can also tell if the blood is a brighter color, though it is not always the case. Basically, pain despite being able to register, means you are in an artery and you need to pull out right away. You're probably fixing into your medial cubital vein, the one in the crook of your arm. There are the brachial and ulnar arteries close by, but they're usually deeper and harder to hit by accident. If you start shooting into spots in your wrist and hand, it becomes much easier to tag an artery. Check out some vein and artery charts online, study them and try to map out your veins in relation to the chart. It really comes down to knowing your own body and lots of experience. Again, check the IV megathread. http://www.bluelight.ru/vb/threads/...nt-To-Suck-Your-Blood?p=10188168#post10188168

Tommy and mr scagnattie have covered it. It's only necessary to register once if you are confident you haven't moved the needle and it is still in the vein. Re-registering is a good way of checking if you are unsure. Don't register over and over multiple times however as forcing blood cells back and forward through a narrow syringe can damage them and cause haemolysis. Registering once or twice is fine though, just don't do it over and over so the whole syringe fills with blood.

The IV megathread mr scagnattie has linked covers identifying veins and arteries. You should be able to identify which is which just from feel alone - arteries are pulsatile where as veins do not. Veins have a distinctive bouncy feel too, when you get accustomed to how they feel. Vein /artery maps can be useful, but people's anatomy isn't always the same as the textbooks show, so make sure you can confidently tell the difference. When you hit an artery, the blood is under a lot more pressure, so it can flow into the syringe with more force, and sometimes the blood looks brighter although this is unreliable. Arterial infections are also often more painful as arterial walls have their own nerve supply, but again this is unreliable.

If you suspect you have hit an artery you need to stop, remove the needle and apply firm pressure. If you have injected into it, or if you are concerned at all, you should seek medical help as arteries can spasm, cutting off the blood supply to the limb.
