Answer

The key to off-pump coronary artery bypass grafting (OPCABG) is the maintenance of blood pressure, heart rate, and normothermia (with the use of warming blankets). Preload must be optimized during manipulation of the heart to minimize hemodynamic instability. A number of techniques can be used to prevent hypotension, including prophylactic intravenous (IV) fluid infusion, use of the Trendelenburg and reverse Trendelenburg positions, and low-dose alpha-agonist infusion. [55]

A systematic review did not demonstrate any significant benefit of (OPCABG) compared with on-pump CABG (ONCABG) regarding mortality, stroke, or myocardial infarction. [56]
