The section Daily EDAIC-MCQ series covers a different topic each day with the intent that candidates can prepare one small topic each day, making steady progress in their exam preparation.
Question: Following statements are true regarding cardiopulmonary bypass:
- The target ACT before the initiation of the bypass should be less than 400 seconds
- The use of heparin-coated CPB circuit can abolish the inflammatory response to bypass circuit
- The target mean arterial pressure during CPB is between 80-100 mmHg
- At the start of bypass, the arterial cannula is slowly opened first followed by the venous cannula
- Potassium cardioplegia is given as a single bolus after aortic cross clamping.
Explanation:
- target ACT should be more than 400 before initiation of the bypass
- heparin-coating of the CPB circuit and oxygenator significantly blunts the inflammatory response to the CPB circuit but does not abolish it.
- MAP during CPB should be between 50 and 80 mmHg. BP > 100 mmHg is considered hypertension and needs immediate treatment.
- the venous cannula is always opened first before the arterial clamp is removed to establish the CPB
- cardioplegia needs to be repeated after every 15-20 minutes or given as continuous infusion for compensating for the continuous washout
Answers:
- false
- false
- false
- false
- false
