Abstract

SILVA, Luis E et al. Surgical site infection rate in coronary artery bypass grafting surgery at the Fundación Santa Fe de Bogotá. Rev. Colom. Cardiol. [online]. 2011, vol.18, n.3, pp.158-161. ISSN 0120-5633.

Background: mediastinitis has been reported in up to 4% of patients undergoing CABG with a mortality approaching 25%. It is a potentially lethal complication of multifactorial etiology that influences patient's life quality and prognosis and generates besides a high cost. Safenectomy infection with associated high morbidity has been reported in up to 25% patients. Objectives: to determine the rate of infection of the superficial and deep surgical site after myocardial revascularization in patients operated in the Fundación Santa Fe de Bogotá that received gentamicin and vancomycin prophylaxis in accordance with the institutional protocol. Methods: retrospective cross sectional study conducted in 228 patients undergoing CABG surgery at the Fundación Santa Fe de Bogotá during a period of four years (January 2006 to December 2009). Results: of the 228 patients, six had infection of the superficial surgical safenectomy site (2,63%), one had sternotomy dehiscence without mediastinits (0,43%) and one had surgical site superficial infection of the sternotomy (0,43%). No deep surgical site infections occurred (sternotomy or safenectomy). Conclusions: the antibiotic prophylaxis used in the Fundación Santa Fe de Bogotá for cardiovascular surgery has demonstrated lower surgical site infection incidence, both superficial and deep, compared to the recommended in the ACC/AHA guidelines, without increment in the incidence of resistance to the antibiotics used.

Keywords : mediastinitis; surgical site infection; safenectomy; antibiotic prophylaxis; cardiovascular surgery.
