Bubbles in the syringe

[cherrydrpepper]

Does anybody have a technique that works well to get them out?

[Noles12]

I always use a bubble of about half a cc when i inject.

Its easy to get rid of them though. Just pull back a little in the plunger. Then flick the syringe on the side so all the bubbles go to the top. Then push the plunger up with the needle facing up

My goal is no bubbles and this is why. This is talking about what happens when air enters a vein during intravenous treatment.

"Air bubbles of less than 30 milliliters are thought to dissolve into the circulation harmlessly. Small volumes do not result in readily detectable symptoms, but ongoing studies hypothesize that these "micro-bubbles" may have some adverse effects. A larger amount of air, if delivered all at once, can cause life-threatening damage to pulmonary circulation, or, if extremely large (3-8 milliliters per kilogram of body weight), can stop the heart.

One reason veins are preferred over arteries for intravascular administration is because the flow will pass through the lungs before passing through the body. Air bubbles can leave the blood through the lungs. A patient with a heart defect causing a right-to-left shunt is vulnerable to embolism from smaller amounts of air. Fatality by air embolism is vanishingly rare, in part because it is also difficult to diagnose."

Well seeing as i have never injected IV, im not worried about that at all. I have around 100 injections with an air bubble and never once has it affected me. If your in a vein you should know before you get anywhere near the air bubble

Air simply dissolves in a muscle

I flick it then purge it but don't get too meticulous with it. A little air won't hurt you.

Ok I see your logic. You first make sure you aren't in a vein by aspirating and then you are gtg. Apologize if I came across as ambushing with my copy paste job.

The air bubbles won't hurt you. You'll be fine.

Its fine. I understand why you would worry. But yeah, i aspirate with the needle facing down in the muscle so the bubbles is in the top . If i am in a vein i have neither injected oil nor air so it wouldnt matter. Just pull it out replace needle and move over a little, inject again, aspirate, if no blood inject.

The air will help to push the oil that remains in the top of the needle. Once in the muscle it will just dissolve and you will never know the difference

Change the draw nedle.

[kenny1022]

I have a pretty good fail safe technique that gets rid of the bubbles. When drawing out gear, I deliberately go way beyond the intended dosage. Afterwards, with the needle still in the vial, I push the plunger up to the amount that I plan to inject. This process usually gets rid of all the bubbles for me without losing any gear.

[Noles12]

Change the draw nedle.

What did that have to do with anything he was asking here?

When we use a smaler nedle to draw with. Then do we get bubbles in the syring. If u change the draw nedle to a bigger one. Do u get less or zero bubbles in the syring... maby i missunderstand the question. SORRY !!

[Noles12]

I think he was asking how to get the air out after he has drawn the oil. No matter what gauge, big or small, unless i pull some gear, push it back in, then pull again, i always get air. But like i stated earlier it doesnt bother me. I actually pull more air before the injection
