Objectives: 

Hospital infections continue to be a major problem, causing high morbidity and mortality in surgical clinics and significantly increasing the length of hospitalization and cost of treatment. Nosocomial bloodstream infection have repeatedly identified as the most frequent type of nosocomial infections in pediatric patients. Although, it is known that the frequency of infectious complications, as well as their etiology is rather different in various geographical regions, sometimes even at the concrete hospitals.

The aim of our study was to determine the frequency and etiology of hospital bloodstream infection following cardiac surgery in children and to find out whether the emergency operation increases the frequency of bloodstream infection or not.

Methods: 

We studied 421 patients at Paediatric Cardiac Surgery Clinic, who were operated in the period from January 2001 till December 2004. The age of the patients varied from 1 day to 18 years. In 383 cases the operations were planed and in 38 cases-emergency.

Results: 

Out of 421 patients hospital infections occurred in 66 (15.7%) patient. The frequencies of infectious complications were as follows: pneumonia -32 (7.6%), bloodstream infection -14 (3.3%), wound infection -10 (2.4%), urinary tract infection -7 (1.7%), endocarditic -2 (0.5%), pericarditis -1 (0.2%), non differentiated site infection -12 (2.9%). The most cases of bloodstream infections occurred in children < 1 year of age. Bloodstream infection in 6 cases were caused by Gram-negative bacteria: Klebsiella pneumoniae-3, Serratia marcescens-2, Acinetobacter baumanni -1 and in 8 cases by Gram-positive bacteria: Staphilococcus epidermidis -7, Streptococcus salivaris -1. The rate of bloodstream infections following 383 planed operations was 3.4% and after the 38 emergency operations-2.6%.

Conclusion: 

The bloodstream infection was the second most frequent infectious complication following cardiac surgery in children. In the etiology of bloodstream infection the most frequent gram-positive bacterium was Staphilococcus epidermidis and the most frequent gram-negative bacteria-Enterobacteriaceae. The frequency of bloodstream infection was not significant different between emergency (2.6%) and planed operations (3.4%).
