METHOD FOR ASSESSING THE SEVERITY OF VENTILATOR-ASSOCIATED PNEUMONIA IN CEREBRAL STROKES Russian patent published in 2019 - IPC A61B5/08 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to neurology, and can be used for assessing the severity of ventilator-associated pneumonia in cerebral strokes. Patient's age, presence of organ failure and patient's presence on artificial pulmonary ventilation (APV) are determined. Additionally, sex, presence of ischemic or haemorrhagic cerebral stroke, duration of patient's APV, presence of infectious agent, pre-existing structural changes in an organ are determined. Each feature is scored, scores are summed up and severity is determined. Age over 50 years is estimated as 5 points; male gender is evaluated as 5 points, female gender – as 0 points. Presence of multiple-organ failure is assessed as 7 points; presence of haemorrhagic cerebral stroke is assessed as 5 points, ischemic as 7 points. Duration of mechanical ventilation of 1–3 days is evaluated as 2 points, 4–7 days – as 3 points, 8–14 days – as 4 points, more than 2 weeks – as 5 points. Level of the inflammatory process in the lungs within the segment is assessed as 2 points, polyspecific – as 4 points, share – as 6 points, drainage or total – as 8 points. Detection of mixed flora in inflammation focus is evaluated as 6 points, Kl. pneumoniae – as 4 points, Staph, aureus – as 2 points, other infectious agents – as 1 point. Preexisting tissue structural pre-existing changes are evaluated as 4 points. If there is no data on one of the parameters, its score is equal to 0. Then, when the number of points from 12 to 20 assess the severity of pneumonia as light, score of 21 to 29 points being average, and 30 to 47 points being considered severe.

EFFECT: method provides higher accuracy and simplified method for assessing the severity of ventilator-associated pneumonia in cerebral strokes by means of available and simple indicators and standardization of evaluation.
