Q

What is Ischemic Reperfusion Injury?
*How do we get this
*How do we prevent this

A

When the Aorta has been clamped too long, it becomes ischemic; the clamp is let go too quickly and blood rushes to the arteries, causing for blood to pour in and hyper-oxygenation
*Prevent by assessing O2 status of Pt before and by unclamping the Aorta slowly
