Mrs. W., a patient on a cardiac step-down unit, is receiving a dopamine IV infusion.
When the nurse first comes on the late-night shift, Mrs. W. seems just fine. However,
the next time the nurse checks on her, the IC line ahs dislodged and the infusion has
infiltrated. What could happen as a result? is this serious? What treatment will the nurse
expect to see ordered? Describe the procedure and provide the rationale.
✅Extravasation can cause vasoconstriction and ultimately tissue death (necrosis). If
the vasoconstriction is not reversed quickly, the whole limb can be lost. Phentolamine,
an alpha blocker, can reverse this potent vasoconstriction and restore blood flow to the
ischemic, vasoconstricted area. When phentolamine is injected SQ in a circular fashion
around the site, it causes alpha adrenergic receptor blockade and vasodilation. This in
turn increases blood flow to the ischemic tissue and thus prevents permanent damage..
