Antibacterial Tactics Based on Presepsin Level in Thoracic Aorta Surgery Patients

Various biomarkers are being used to improve the quality of prediction models aiming to improve clinical outcomes and reduce mortality in the cardiac surgery patient population. In particular, presepsin and procalcitonin have comparable prognostic value for adverse renal, cardiovascular and respiratory outcomes in cardiac surgery patients. In addition, presepsin has in-hospital, 30-day, and 6-month prognostic mortality rate value and is also highly effective for the early diagnosis of sepsis in patients in the intensive care unit. In the previous study the absence of an increase in the level of presepsin in the first 6 hours after surgery was associated with an increased risk of developing a complicated course of the postoperative period (OR 4.15, 95% CI: 1.83-9.41). The combination of two risk factors - a presepsin level at the end of surgery \>519.5 pg/ml and the absence of an increase in the presepsin level in the first 6 hours after surgery was associated with an increased risk of developing a complicated course of the postoperative period (OR 5.80, 95% CI: 2. 19-15.35). The hypothesis of this study suggests that in case of insufficient prevention of infectious complications, based on the dynamics of presepsin, it is permissible to administer the broad-spectrum drug ampicillin/sulbactam 3 g. every 6 hours for at least 72 hours from the date of surgery. It is expected that changes in the tactics of antibacterial therapy will reduce the number of inflammatory complications in patients undergoing surgery on thoracic aorta.
