INVESTIGATION OF RESPIRATORY INFECTIOUS AGENTS IN PEDIATRIC CARDIAC SURGERY
Objective. The objective is to determine the efficiency of different ways of receiving samples of sputum from lower respiratory tract in order to investigate microbiological agents of infectious respiratory tract complications in cardiac surgery. Materials and methods. 15 pediatric patients with congenital heart diseases were included into the study. All of them were examined with suction catheter microbiological investigation during the respiratory tract sputum collection or through performed fibrobronchoscopy. Results. Efficasy of using of suction catheter for taking material was associated with 86,7% positives results. We revealed in 44 (91,7%) cases single culture microorganisms. 87,5% samples were identified as Gram-negative microbes and Gram-positive microorganisms were revealed in 12,5%. Use of bronchoscopy allowed to take the combinations of microorganisms in 96,2% cases. Most of microorganisms were Gram-negatives samples - 62,7%, and the part of Gram-positives microorganism was - 37,3%. Summary. Correct use of sputum collection techniques through suction catheter and fibrobronchoscopy provides high percentage of positive results in microbiological investigation (up to 87%), therefore it helps to determine the etiology of infectious airways complications. Sputum collection during bronchoscopy give more precise (in 96,2%) identification of microbiological agents of infectious respiratory tract complications in cardiac surgery.
