The occurrence of postoperative myocardial infarctions, new onset atrial fibrillation, re-operation for bleeding, vasopressor support in SICU, inotrope support in SICU, and postoperative requirement for intra-aortic balloon pump are indicators of hemodynamic instability.
Although the literature does not specifically support this practice, there have been reports of using 10-15 times the maximally recommended infusion rate of DEX without respiratory depression or hemodynamic instability.
Also papillary muscle rupture (PMR) is usually seen 2-9 days after the infarction and causes serious hemodynamic instability, cardiogenic shock and pulmonary edema with mitral regurgitation (3).
