METHOD OF PREDICTING RISK OF DEVELOPMENT OF DIGESTIVE TRACT BLEEDING IN CASE OF POLYPECTOMY WITH APPLICATION OF HIGH-FREQUENCY CURRENT Russian patent published in 2011 - IPC A61B10/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to surgery, endoscopy, gastroenterology, and is intendeds for predicting risk of development of digestive tract bleeding in case of polypectomy with application of high-frequency current. Laser Doppler flowmetry is carried out. By means of skin sensor on finger average initial value of blood microcirculation index - Im₀ is determined. After that, standard occlusion test with three-minute occlusion of brachial artery is performed. Maximal value of blood microcirculation index is determined during maximum of reactive post-occlusion hyperemia- I_mmax. Increase of blood microcirculation index K_ii is calculated by formula K_ii=I_{m max}/Im₀×100%. If said index achieves value 100-115%, risk of bleeding development in case of polypectomy is predicted.

EFFECT: method makes it possible to ensure non-invasive and reliable prediction of possibility of post-operational bleeding development in case of polypectomy individually for each patient due to examination of blood microcirculation.
