Abstract

Background: Children who have undergone cardiac surgeries due to congenital heart disease are prone to various kinds of infections. Objectives: This study was done to investigate the prevalence of nosocomial infections and microbiology of post-cardiac surgery infections in pediatric patients with congenital heart disease (CHD). Methods: In this cross-sectional study, the epidemiology and microbiology of post-cardiac surgery for pediatric patients with CHD at Imam Reza Hospital of Mashhad University of Medical Sciences between 2014 and 2017 were investigated. Demographic and clinical information was recorded, and the findings were analyzed using SPSS 16. Results: Out of 1128 patients with open heart surgery during the four years of the study, 135 patients, including 80 males (60.1%) and 55 females (39.9%) with a mean age of 8.06 ± 3.86 months, were enrolled in the study. The prevalence of infection was 11.96%. The most common isolated bacteria were Acinetobacter (19/135, 14.1%), Pseudomonas spp. (13/135, 9.6%), and Enterobacter (13/135, 9.6%) as Gram-negative ones and Corynebacterium diphtheria (10/135, 7.4%) and Staphylococcus epidermidis (10/135, 7.4%) as Gram-positive types. Candida albicans (14/135, 10.4%) were also the most frequent fungi. The frequency of infection-causing masses did not differ significantly between different cardiac abnormalities (P = 0.831), sex (P = 0.621), age (P = 0.571), and weight (P = 0.786) groups. Also, the duration of hospitalization, intubation, bypass time, and urinary catheterization in positive culture cases were significantly longer than in negative cases. Conclusions: In our study, the most common infections in children who underwent heart surgery were Acinetobacter, C. albicans, Pseudomonas, and Enterobacter. It is suggested to reduce the hospitalization, intubation, bypass, and urinary catheterization time to reduce nosocomial infections in these patients and decrease treatment costs.
