Insomnia is one of the most common clinical syndromes of somnological disorders, including any sleep disorders under sufficient time and appropriate sleeping conditions. Significant sleep disturbances are common in children who enter the intensive care unit. Between 18 and 65 per cent of children aged between 2 and 18 hospitalized in the intensive care unit have a clinical condition of acute confusion, better known as delirium. Sleep fragmentation, reduction of total sleep time, lack of slow, deep sleep and rapid sleep, and shift of sleep time are changes that can also act as insomnia triggers. Their presence worsens the course of the disease in the patient, prolongs the hospital stay, and increases the risk of complications and lethality. Circadian sleep disorder is a condition that requires close monitoring. Although insomnia therapy approaches are not yet reliable, early diagnosis of insomnia can reduce the duration of the delirium. Sleep assessment includes questionnaires and diaries. However, it was recognized that, despite the difficulties in implementing and interpreting polysomnography, it was still a gold standard for more accurate detection of changes in sleep phases and the difference between normal and abnormal sleep. In the absence of a polysomnograph, it is permissible to use a prolonged video assisted EEG. The inventive multimodal video-assisted monitoring method makes it possible to diagnose sleep disorders, pain syndrome and differential diagnosis of apnoea with cardiac and conductivity disorders or abnormal brain activity, including the presence of sub-clinical convulsions in patients of high-risk groups using a safe and non-invasive method for analyzing trends in the total bioelectric activity of different biological structures of a child. The validation of questionnaires according to the age of the child is also an important step in the timely diagnosis of sleep disorders in older children.

Allergic diseases are one of the main problems today. Almost 15% of the child population suffers from allergic diseases. Respiratory allergies account for a significant share and currently the prevalence of asthma in the world — 5–10%. Purpose — to assess the anamnestic risk factors for the development asthma in children with recurrent wheezing. Materials and methods. Analysis of clinical data of 96 children aged 1 year 6 months to 6 years 11 months with recurrent episodes of bronchial obstruction, who were examined and treated in the municipal non$profit enterprise «City clinical children's hospital No. 16» Kharkiv City Council. Patients have the inclusion criteria in the study. Children were observed before the age of 6 years to verify the diagnosis of asthma and were divided into groups. Group I included 15 patients with asthma. Group II — 81 patients who had recurrent wheezing. Results. Among the anamnestic data were significant adverse factors in the formation of asthma. The nature and strength of the relationship between these factors have been established. The connection with the formation of asthma in children was evaluated. Conclusions. The established data can be used in the algorithm of examination of patients with wheezing. It`s able to identify the risk groups of children for the formation of asthma. Collection of anamnesis and identification of these risk factors can be used to predict the formation of asthma in children less than 6 years. 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 interest was declared by the authors.
