Question

Blanching of a vein into which norepinephrine (NE) is being infused together with induration and pallor (cool, hard, pale) of the tissues surrounding the IV site are signs of what and its Treatment?

Answer 1

Induration and pallor of tissues surrounding the IV site along with blanching of the vein are signs of tissue ischemia. Treatment includes discontinuing the infusion and applying warm compresses.

Step-by-step explanation:

Norepinephrine (NE) is a vasoconstrictor, meaning it causes the narrowing of blood vessels. When NE is infused into a vein, it can cause blanching of the vein and induration and pallor of the surrounding tissues. This occurs because NE constricts the blood vessels in the area, reducing blood flow and oxygen supply to the tissues.

The signs described are consistent with tissue ischemia, which is a reduction in blood supply to the tissues. Treatment for this condition involves discontinuing the infusion of NE and assessing the IV site for potential complications such as extravasation or infection. Warm compresses can be applied to the area to promote blood flow and tissue healing.
