Asymptomatic Bacteriuria and the Impact of Treatment on Surgical Site Infections in Coronary Artery Bypass Grafting Surgery Patients

Abstract

Background. Evidence for asymptomatic bacteriuria (ABS) treatment in the preoperative management of cardiac surgery is limited, resulting in uncertainty and variations within practice. Unnecessary treatment of ASB may lead to the development of antibiotic resistance, loss of endogenous microflora, potential side effects, and increased costs. However, potential perioperative hematogenous spread of genitourinary bacteria may increase the patient's risk for postoperative infections including surgical site infections (SSI). The primary purpose of this study is to evaluate whether treatment of ASB has an impact on the occurrence of SSIs specifically in non-valvular coronary artery bypass grafting (CABG) patients.
