Dobutamine (treats heart failure and cardiogenic shock) @ 10 micrograms/kg/min.
1 mg of midazolam (muscle relaxant)
20-gauge right radial arterial line is inserted (monitors blood pressure) using anesthesia (2 mg of midazolam, 100 mg of lidocaine [treats abnormal heart rhythms], 14 mg of etomidate [helps with induction of anesthesia], 100 micrograms of fentanyl [sedative], and 20 mg of Vecuronium bromide [muscle relaxant]
8 mm endotracheal tube, anesthesia was maintained with 0.4%-0.6% isoflurane and a 60% oxygen and air mixture
right internal jugular 9-French multilumen introducer using the Seldinger Technique (to obtain safe access to blood vessels) for analysis Steps taken and drugs required Two units of blood removed
A 10% dextrose drip carrier & aminocaproic acid (inhibitor for enzymes) infusions
NO @ 20 parts per million (decreases pulmonary ventricular resistance)
probe inserted assessment
Antibiotics administered with divided doses of 400 microgrmas of IV fentanyl Pre-surgery Pre-heart switch Incisions to remove patient’s heart
Blood coagulation inhibitors admin'd
tubes inserted into heart remains
