The risk of developing ARF after cardiopulmonary bypass for cardiac surgery is highest in what age group?
a) Adults
b) Children
c) Infants
d) Neonates
Click for Answer
Answer
Answer d. Cardiopulmonary bypass replaces the normal pulsatile blood flow to the kidney with continuous perfusion. The loss of systolic peaks results in decreased renal medullary perfusion; in the neonate (whose autoregulatory mechanisms are not intact), there is a high risk of acute renal failure.
