| Principles of CPB and an associated side effect: |
|
Definition
1. Hemodilution: Due to machine roller clamps; H&H falls initial, then again as kidney clears the debris. RIsk of ATN and fluid retention.
SE: Decreased H&H
2. Hypothermia: Cooled body temp during surgery, halts coagulation cascade; reduces O2 consumption, increase SVR, Risk of repeat hypothermia during rewarming as cool blood returns to the warmer core after surgery.
SE: Vasoconstriction, bleeding (halts coagulation pathway), VFib spontaneous
3. Anticoagulation: bleeding, risk of tamponade, rebound heparin with short half life of protamine sulfate. Blood administration more commonly given in redo CABG pts |
