METHOD FOR PREDICTION OF ONSET OF PAIN SYNDROME IN PATIENTS AFTER THORACIC ABDOMINAL OPERATIONS Russian patent published in 2019 - IPC A61B5/91 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to anesthesiology and critical care medicine, and can be used to predict the onset of pain in patients after thoracoabdominal surgeries. Prior to and after the operation, the volume of maximum inhalation in ml is determined by the loading spirometer in the patient. Volume of maximum inhalation before operation is taken as 100 %. If the volume of the maximum inhalation after operation is 68±2 % of the initial value, the pain syndrome is predicted 25–30 minutes after the examination. If the volume of maximum inhalation after operation is 58±2 % of the initial value, the onset of pain syndrome is predicted 15–20 minutes after the examination.

EFFECT: method provides a timely prediction of the onset of pain syndrome, which enables anticipatory anaesthesia and reduces the number of hospital days in the resuscitation and intensive care unit.
