Acute respiratory viral infections (ARVI) are an urgent problem in young children, which is due to their significant prevalence, they have a constant tendency to increase and occupy the first places in the structure of infectious diseases. Damage to the mucous membranes of the upper respiratory tract in children with ARVI lead to numerous problems that require adequate replacement of the main functions of the child’s body, which determined the relevance of our study. Purpose - to analyze the effectiveness of the use of isotonic dilution of sea water (Pshyk Mini medicine) for irrigation therapy in nasal congestion in infants and young children caused by acute respiratory infections. Materials and methods. A comprehensive examination of 100 infants and young children with influenza and other ARVI was conducted in the infectious diseases department of the Chernivtsi Regional Children’s Clinical Hospital. The children were randomly divided into 2 clinical groups: the Group I included 55 children (average age - 1.09±0.3 years, the proportion of boys - 58.1%), who, as part of complex standard therapy, received nasal irrigation using 2-3 drops of Pshyk mini medicine in each nostril 3 times/day. The Group II included 45 patients (average age - 1.15±0.2 years (p>0.05), the proportion of boys - 59.1% (p>0.05)), in whom isotonic sodium chloride solution was used for the purpose of the nasal sanitation. Results. The conducted studies showed that starting from the 3-4th day of hospitalization, a statistically significant decrease in catarrhal manifestations and the severity of nasal obstruction was noted in patients of the Group I who received Pshyk Mini in complex treatment. In particular, in relation to the results of the Group II, in the children of the Group I, on the 4th day of inpatient treatment, the chances of reducing the severity of catarrhal manifestations (estimated ≤2 points) increased: the absolute risk increase - 53.0%, the relative risk increase - 67.9% (95% CI: 57.8-76.9) with the minimum number of patients who need to be treated to obtain a positive result - 1.5. We also established that compared to the representatives of the Group II, children of the Group I had almost a 4-fold increase in the chances of restoring tolerance to feeding (estimation of feeding difficulties ≤2 points): attributive risk - 30.5%, relative risk - 1.6 (95% CI: 0.6-4.8), odds ratio - 3.9 (95% CI: 1.2-12.3). Conclusions. For the purpose of unblocking of nasal breathing in infants and children of early age at the background of acute respiratory viral infections, the use of an isotonic solution of sea water (Pshyk Mini medicine) has a number of significant advantages compared to the use of an isotonic solution of sodium chloride for this purpose. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.
