METHOD OF TREATING PURULENT-DESTRUCTIVE PULMONARY DISEASES Russian patent published in 2022 - IPC A61B17/00 A61M1/00 A61B10/04 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to thoracic surgery. Thoracoport is placed in a projection of the destruction cavity, a video thoracoscope is inserted into the destruction cavity to assess the degree of manifestation of the inflammatory process and the presence of bronchopulmonary fistulas. Destruction cavity is sanitized, followed by installation of a drainage system in the cavity through a thoracoport in the form of a fine-pored sponge with a double-lumen drainage tube passing through the entire volume of the sponge and with its distal end fixed to the base of the sponge. Thoracoport wound is closed and sealed. Pathological discharge of cavity is vacuum-aspirated at a negative pressure of 8–10 kPa until the cavity is cleaned, followed by an increase in the negative pressure to 15–18 kPa. Vacuum aspiration is performed until the cavity is closed by granulations or the destruction cavity is reduced to the size of not more than 60 mm in diameter. In the process of vacuum aspiration, an antiseptic solution is introduced drop-by-drop into the destruction cavity through the lumen of the drainage tube. On 3rd-4th day after the beginning of the vacuum aspiration, the drainage system is changed with the vacuum-assisted dressing, which is changed every 3–5 days. In the process of changing the drainage system with a vacuum-assisted dressing, a videothoracoabscessoscopy of the destruction cavity is performed. Fine-pored sponge used is a sponge whose volume exceeds the volume of the destruction cavity by 1.5 times and provides filling the entire destruction cavity with the sponge while maintaining its aspirating properties.

EFFECT: method provides reducing the length of treating the patients by improving the quality of debridement of the purulent focus, reducing the number of surgical injuries while ensuring control of the inflammatory process in the lungs.
