Keywords: weaning, mechanical ventilation, children


The aim of the research was to establish criteria for successful weaning from mechanical ventilation in children based on analysis of Paediatric rapid shallow breathing index, maximum amplitude of diaphragm movements, diaphragm thickening fraction and pressure support (PS), which ensure minimal respiratory muscle load, level of consciousness which ensure minimal respiratory muscle load and presence of cough and swallowing reflexes and previous unsuccessful attempts of weaning.

Investigated problem: there is no consensus on the basic physiological parameters for successful extubation that have to be achieved during weaning from mechanical ventilation in children due to variability in size and degree of maturity of lungs and patients’ comorbidities. It leads to the lack of clinical justification for the routine practice of weaning in children.

The main scientific results: We have established a list of causes of unsuccessful weaning depending on the function of the diaphragm in children with different types of respiratory failure.

We have clarified and supplemented the list of reasons for unsuccessful weaning from mechanical ventilation depending on nutritional status and level of serum electrolytes in children.

We have identified and supplemented the list of reasons for unsuccessful weaning from mechanical ventilation depending on the disorders of neurological status in children.

We have supplemented the algorithm for predicting difficult weaning from mechanical ventilation in children.

The area of practical use of the research results: the obtained results have to increase the rate of successful weaning in children with acute respiratory failure in pediatric intensive care units.
