Q: It is important to avoid hyperthermia after Cardio-Pulmonary Bypass (CPB). Out of following which organ failure has shown to be associated with hypethermia after CPB?

A) Liver
B) Kidney
C) Right heart
D) Pancreas
E) Adrenal


Answer: B

Hyperthermia (body temperature more than 37°C) after CPB has shown to be  associated with Acute Kidney Injury (AKI), worsened neurologic and neurocognitive outcomes and mediastinitis.
