Hi guys..i have done a medical course..i know it's corticosteroid injection used to treat keloid & i have given few injections with positive results...but when i insert the injection in hard keloids, its very difficult to push the medicine so i take it out.My gf has few keloids on her chest but she says it's very painful when her doctor inserts the needle but less painful when i do that.Those soft keloids are almost gone but hard ones are still there joint to each other.So please tell me how to push inside them? Is it bcoz i'm doing it wrong way? Do i have to adjust my needle?Any video links "how to push inside hard keloids"? Any small or less thicker needle for keloid treatment with pic please? Is there any cream or ointment to soften them?
10 points! for the right answer with your best details pls.
Don M - Don't know about keloids, but speaking as someone (type 1 diabetic with past history of trigger finger) who has had to deal with difficult injections in the past, here's some advice:
ReplyDelete1) If it isn't going in well, don't push it... unless there's no choice.
2) Use the thinnest needle you can... it will go in easier, but keep in mind that venturi's principle works here (from fluid dynamics): pushing the same volume of fluid through a narrower tube produces the same flux (volume per unit time) but a faster linear velocity due to the constricted cross-sectional area. That means that the liquid will come out fast, but not a lot at a time. Pushing harder will just increase the speed of the liquid into a very tiny, cramped space, and will be VERY painful. It will be like pressure washing the inside of the keloid. So push the fluid in slowly and be very patient.
3) If you get any bleeding, patient complains of burning or shooting pain, you have a bad injection site, and move it.
4) Don't use cream or ointment unless you intend to push that inside the wound you make with the needle. Just sterilize the site as required in normal prep.
5) Steroids tend to go in pretty thick, and they tend to burn, and in very tight spaces they are very painful. Sometimes you can't avoid this. But IF you can, please do.
Good luck.
