FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to paediatric surgery, and can be used for predicting results of operative treatment of rectum and anus atresia in children. Anorectal area is examined by methods of laser Doppler flowmetry, optic tissue oxymetry and laser fluorescence in not less than 4 points. In each of the points determined are: index of microcirculation - Ivolume of blood filling - V, index of blood oxygenetion - SO; intensity of radiation of collagen and elastin fluorescence - I, Iand intensity of diffused laser radiation I. Specific consumption of oxygen by tissue, as ratio SO/V, ratio of index of microcirculation to volume of blood filling- I/Vare calculated and coefficient of fluorescent contrast of fraction of tissue proteins ?is determined by means of computer processing. All obtained values on 4 points are averaged to obtain average values of SO/V; ?, and if values SO/V?0.01-2, I/V=0.01-1; ?=0.01-1, prediction is estimated as favourable.EFFECT: method makes it possible to estimate change of blood flow, hypoxia and disorganisation of intercellular components of connective tissue of anorectal area in a reliable way and make prognostic conclusions as to selection of individual treatment.2 ex |
