Trace Element Status and Postoperative Morbidity After On-pump Coronary Artery Bypass Surgery

Trace elements are essential micronutrients that take part in most antioxidant reactions in the body. In this study, we evaluated the levels of copper, chromium, manganese, selenium, magnesium, zinc, iron, and silicon in adult patients who undergone isolated on-pump coronary artery bypass with the occurrence of postoperative atrial fibrillation, transient renal injury, transient liver injury, and rate of wound infection; 51 adult patients (41 men, 10 women) underwent isolated coronary artery bypass grafting (CABG) under cardiopulmonary bypass. The mean age was 61,9 ± 8,0 years (range 45–82 years). Blood samples were collected preoperatively, postoperative first hour, postoperative first day, and fifth postoperative day for element analysis. Serum levels were determined by an Inductive Coupled Plasma Optical Emission Spectrometer (ICAP 6000). Serum copper, zinc, and selenium values, typically known as strong antioxidant elements in the body, decreased significantly during the first hour and first day of postoperative period compared to the preoperative period ( p
