Microbial Contamination after Cardiac Surgery in a Hospital Cardiac Surgery Ward

Abstract

Surgery site infection is one of the most common postoperative complications which is associated with increased morbidity, mortality and admission costs. It is considered a priority to determine the level of nosocomial infection and its control in reflecting the quality of care. Therefore, this study aimed to evaluate the microbial contamination after cardiac surgery at a hospital cardiac surgery ward of Besat Hospital, Tehran. In this cross-sectional descriptive-analytic study (2013-2017), 610 patients underwent surgery at the Department of Cardiac Surgery of Besat Hospital. All necessary information such as urine culture, surgical site, histopathologic examination for the diagnosis of microbial contamination and microorganisms were collected from the patient records and inserted in the questionnaire. The data were analyzed using SPSS (version 25). The incidence of nosocomial infections following cardiac surgery reportedly ranged from 17% to 23%. Accordingly, pneumonia (51.2%) and local infections (22%) were the most common infections in the studied population. The mortality rate in our population was 11.4%. Moreover, 64.3% of the total mortality cases were reported in patients with sepsis. The mean age and duration of admission of patients with catheter infection were significantly higher than other subjects. Given the relatively high prevalence of the infection and its importance, it is necessary to take more serious measures to prevent and control these infections.

Surgical Site Infection in Cardiac Surgery

“…It is difficult to estimate the incidence of infection in cardiac surgery patients, with reported rates ranging between 3.5% and 26.8% [ 10 , 15 , 16 , 17 , 18 ]. SSI incidence after cardiac surgery varies depending on the quality of local epidemiological surveillance, SSI definition used, patient profile and the type of cardiac procedure [ 19 ].…”

Factors associated with surgical site infection in myocardial revascularization: a retrospective longitudinal study

“…The most common complications of cardiac surgeries are infections. An international study investigating microbial infections after cardiac surgery in cardiac surgery wards, conducted with 123 patients, found that 17-23% of patients develop SSIs after cardiac surgical procedures, as these patients have higher risk factors and vulnerabilities (4) .…”

“…A complicação mais recorrente das cirurgias cardíacas são as infecções. Um estudo internacional com o objetivo de investigar infecções microbianas após cirurgia cardíaca em enfermarias de cirurgia cardíaca, desenvolvido com 123 pacientes, verificou que de 17% a 23% dos pacientes apresentam ISCs após procedimento cirúrgico cardíaco, uma vez que esses pacientes possuem maiores fatores de risco e debilidade (4) .…”
