METHOD FOR PREDICTING THE DEVELOPMENT OF POST-SURGICAL PNEUMONIA Russian patent published in 2007 - IPC A61B10/00 

FIELD: medicine, treatment of inner diseases.

SUBSTANCE: the development of post-surgical pneumonia should be predicted due to detecting risk factors, such as: age, time of entering the hospital, tobacco smoking, peculiarities of pre-surgical period, a patient's state at entering the hospital, body weight index, the availability of oncopathology, the availability or absence of chronic diseases of respiratory organs, alterations upon roentgenogram of thoracic organs before operation, the availability of cardiac diseases, the availability of physical signs of rhythm disorders, ECG alterations (before operation), chronic pyelonephritis, the quantity of hemoglobin in peripheral blood before operation, the quantity of leukocytes in peripheral blood before operation, nuclear shift index before operation, Kalf-Kalif's index before operation, ESR before operation, total protein of blood serum before operation, creatinine of blood serum before operation, urea of blood serum before operation, the character of surgical interference, duration of operation, duration of controlled ventilation (CV) both during and before operation. In each risk factor it is important to detect prognostic parameters by giving them a corresponding point. Then one should calculate the index for the risk of post-surgical pneumonia (IRPP) due to summarizing the detected points in all parameters. At IRPP≤-13 one should predict low risk for the development of post-surgical pneumonia, at -13<IRPP<+13 - moderate risk, and at IRPP≥+13 - high risk of the development of post-surgical pneumonia should be stated upon. The innovation enables to increase accuracy of prediction of the present complication due to detecting three risk degrees: high, moderate and low based upon calculating the risk index of post-surgical pneumonia.

EFFECT: higher efficiency and accuracy of prediction.
