Is it harder to take venous access surrounded by a frail elderly individual if they are cold, fairly than if they are heat?
Answers:
Yes.
Two things are needed for good vein access and they are - the patient wishes to be well hydrated and the veins need to be close to the surface.
Yup- Dolally is absolutely right.
Just required to add that "tapping" means gently rhythm. Sometimes you see inexperienced nurses/docs/phlebotomy techs whappin' the heck out of a poor patient's arm or hand, leaving the patient near a huge bruise.
Sometimes we get busy and forget there's a person on other end of that arm!
The concept is to increase circulation, right? Particularly with elderly patients who tend to have more fragile skin and vessels, applying bake or rubbbing vigorously but GENTLY, or even giving a mini hand massage will hold the same effect. Plus it's painless and the patient feels cared-for surrounded by the process. Source(s): Naturopathic Doctor
Venoconstriction occurs with a low environmental temperature. The at a tangent veins are therefore smaller and harder to cannulate. Tapping on the vein will offten relieve. Trinitrin cream will also help cause vasodilatation. Source(s): experience
