Q

2 functions of coronary sinus balloon

A

Prevents back flow

Holds cannula in place

20
Q

Unique place can give CPG in Peds

A

Ligamentum arteriosum

21
Q

Advantage of Del Nido and Custodial CPG

A

Last longer, typically only need single dose

22
Q

Del Nido dosage

A

Osmolarity: 340mosm/L
Arrest: 20ml/kg
Maintenance: 10ml/kg
Delivery: 90-180ml/min

23
Q

Components of custodial (Bretschneider) CPG amd their functions

A

Histidine: buffer against acidosis during XC
Tryptophan: stabilizes cell membrane
Ketoglutarate: improves ATP production during reperfusion

24
Q

Affects of MUF

A

Immediate: better pulmonary compliance
24hr: showed no benefit
Affects not sustained because systemic inflammatory response occurs during rewarming also may not be able to overcome capillary leakage

25
Q

Blood flow through ultrafilter

A

20ml/kg/min

26
Q

Benefits of MUF

A

Increased ventricular systolic function
Improved CBF, metabolic activity, and oxygen consumption
Decreased Postop ventilation
Decrease Postop bleeding

27
Q

Most common location of ASD

A

Ostium secundum

28
Q

Formation of ostium secundum

A

Failed growth of the septum secundum or rapid reabsorption of the septum primum

29
Q

Only ASD can close percutaneously

A

Ostium secundum

30
Q

Reversal of the direction of any shunt

A

Eisenmengers syndrome

31
Q

33
Q

Two types of surgical AVAD repair
