In cases undergoing elective coronary surgery, the continuum of perfusion pressures were contrasted in terms of renal dysfunction, neurological impairment or stroke, ICU stay, and mortality. It was a prospective research that ran from March 2014 until February 2017. Total patients (N=467) underwent on-pump Coronary Artery Bypass Grafting (CABG) for 3 vessel coronary artery disease (VCAD=55%), Left Main Stem (LMS=18%), left main equivalent/proximal Left Anterior Descending artery (LAD) lesions (17%), Non-ST-Elevated Myocardial Infarction (NSTEMI) with ongoing ischemia (2.5%), 1-2 Vessel Coronary Artery Disease (VCAD) SPSS 16.0 was used to conduct the statistical analysis.
When compared to the (n1) group, the (n2) group's longer ICU (Intensive Care Unit) stay (>7 days) was substantially higher (p0.05). Lower perfusion (n2) group: 3% mortality; Higher perfusion (n1) group: 1.5% mortality. In the lower perfusion-group, renal dysfunction (Stage 2-3 RIFLE criteria) and postoperative neurological damage were found to be statistically significant. However, there was no discernible difference between the two groups in terms of the frequency of strokes (p=0.09). For two groups, ambiguous information was gathered on the needs for mechanical inotropic support, low Cardiac Output (CO) and perioperative MI. Though it never reached statistically significant levels (p>0.05), the Lower perfusion group (n2) did have somewhat increased ventilatory dependence (>5 days). The whole study was favourable for higher perfusion pressures on-pump for better CABG surgery.
