Secondary outcome measures
1. A Swan Ganz catheter was placed for the assessment and monitoring of arterial pulmonary pressure. This catheter was placed in all 20 cardiac surgery patients undergoing off-pump CABG.
2. Low systemic vascular resistance during cardiac surgery was assessed using a pulmonary artery catheter, and Vigileo monitor for data outcome variables.
3. Difference in perioperative arterial blood pressure measured by Arterial blood pressure was assessed using an arterial radial catheter after ICU admission.
4. Mixed venous oxygen saturation (SVO2) will be assessed by analysis of blood gases by Vigileo monitor.
5. A multidisciplinary team monitored throughout the entire process, the variables of hemodynamics and laboratory results related to cardiogenic shock, post operatory bleeding or other complications by usingVigileo Monitor Edwards Lifescience s, in cardiac surgery patients undergoing off-pump CABG, monitoring the cardiac output of surgical patients who required continuous invasive monitoring during ICU stay. Start in induction of anesthesia, sternotomy, grafting of coronary descending, post-revascularization after ICU.
