Cardiology MCQ 338: Hydration prior to angio

Hydration prior to contrast angiography is useful to:
a) Reduce the chance of contrast nephropathy
b) Reduce the chance of thrombotic episodes in cyanotics
c) Reduce the chance of pulmonary edema
d) a and b are true

["Click here for the answer with explanation", "Correct Answer:"]

d) a and b are true

Good hydration prior to contrast angiography is useful in reducing the chance of contrast induced nephropathy. As dehydration which occurs due to osmotic diuresis after contrast angiography can predispose to thrombotic episodes in those with cyanotic congenital heart diseases with polycythemia, adequate pre-procedure hydration is mandatory in those individuals. In those with severe left ventricular dysfunction care has to be taken to avoid pulmonary edema while hydrating.
