Effect of Intraoperative Hemolysis on Complications Development in Patients with Coronary Artery Disease

The assessment of the degree of IOH was made by the level of free hemoglobin (Hb) on the analyzer HemoCue Plasma/Low Hb, Sweden. In accordance with [Hb] in the blood plasma patients with CABs are divided into 3 groups:1 – without IOH (Hb≤0.1g/l), n=43, 2 – with low IOH (lIOH)–with [Hb]>0.1g/l and<0.5g/l, n=42, 3 with high IOH (hIOH) corresponded to [Hb]≥0.5g/l, n=38. The detection of complications was made in the perioperative (during the operation and the first day after it) and in the early - up to 1 month by dynamic observation of patients. It was detected such complications as arrhythmias, myocardial infarction, stroke, progression of heart failure, death. The study also sought to determine whether specific patient characteristics or surgical techniques influenced the relationship between IOH and postoperative complications [3-5]. By examining these factors, the research aimed to identify patients at highest risk for IOH-related complications and to develop targeted interventions to minimize these risks.
