Summary. Introduction. Bacterial infection of the respiratory tract is highly common among pediatric patients with tracheostomy, yet there is no wide knowledge about the prevalence of different airway microbes, the incidence of bacterial infection, infection risk factors, and complications.
The study aimed to analyze the prevalence of airway microbes, the incidence of bacterial infection, infection risk factors, and complications.
Methods. Retrospective data of officially reported cases were collected from 2018 to 2022 at Riga Children's Clinical University Hospital (RCCUH). Demographic factors, airway microbiological findings, tracheostomy-related complications, underlying conditions, and outcomes for 37 patients were gathered from the hospital's database Andromeda. The data were analyzed using MS Excel. This study received ethical approval from RSU Ethics Committee.
Results. Microbiological analyses were done in 78.3% (n=29) of the cases. Most cultures were obtained from airway aspirate. Altogether 46 different species of microbes were identified. The most frequently identified bacteria were Pseudomonas aeruginosa (in 72.4% of the cases; n=21) and Staphylococcus aureus (65.5%; n=19). Forty-eight percent (n=18) of the patients had respiratory tract infections that required hospitalization. Overall, there were 60 hospitalization episodes of which 51.6% (n=31) were caused by pulmonary bacterial infection, 25.0% (n=15) by non-bacterial infection, and 0.05% (n=3) because of local wound infection. The rest 18.3% (n=11) of hospitalization episodes were due to granulation tissue. The risk factor that showed the greatest significance in the development of bacterial infection was ventilator dependency. Formation of granulation tissue in the airways was found to be the most common complication among pediatric patients with tracheostomy.
Conclusion. This study summarizes the most common pathogens, risk factors, and complications, which should be considered while treating pediatric patients after tracheostomy. The results of this study demonstrate that P. aeruginosa and S. aureus have the highest prevalence among these patients. This research is currently used to develop guidelines for pediatric patients with tracheostomy care in RCCUH.
