METHOD FOR DETERMINING INDICATIONS FOR TANGENTIAL NECRECTOMY Russian patent published in 2024 - IPC A61B8/06 G01N21/64 

FIELD: medicine; combustiology.

SUBSTANCE: invention is used to determine indications for tangential necrectomy. That is ensured by laser Doppler flowmetry before tangential necrectomy. At the first stage, a microvasculature is assessed in an intact skin of a burn wound. Obtained parameters are accepted as the norm. Then zones are marked with an index of microcirculation of burnt tissues below 75% of the norm, requiring excision. If the tissue microcirculation index is 75% of the norm and higher, surgical excisions are not performed. After marking the burn wound, a tangential excision of the wound surface is performed according to the marked zones, and the microcirculation intensity is re-examined. If the tissue microcirculation index is 75% of the norm and higher, the excision is stopped, and if the tissue microcirculation index is below 75 % of the norm, the tissue excision procedure is repeated.

EFFECT: invention allows intraoperative high-accuracy assessment of tissue viability, which provides higher efficiency of necrectomy, accelerates the process of reparative regeneration in the defect area and reduces the risk of developing pyoinflammatory complications, while reducing the length of the surgical intervention.
