METHOD FOR DETERMINING THE VIABILITY OF INTESTINAL SUTURE BAND Russian patent published in 2019 - IPC A61B17/00 A61B5/145 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgery, and can be used in prediction of inconsistency of sutures of intestinal anastomosis after intestinal resection. That is ensured by saturation of arterial blood haemoglobin with oxygen in the intestinal anastomosis ligament. Additionally, oxygen saturation in finger artery is determined. An oxygen viability index of the distal and proximal parts of the retention of the intestinal ligament is calculated in the form of a ratio of the oxygen saturation of the haemoglobin of the distal and proximal parts of the suture band to the index of oxygen saturation of arterial blood haemoglobin on the finger. If the ratio in the distal and proximal parts of the suture band is greater than or equal to one, the intestinal suture band is considered to be viable.

EFFECT: method provides the most accurate prediction of inconsistency of sutures of intestinal anastomosis after intestinal resection by obtaining objective and reliable information on the state of a cross-linked intestinal wall in an anastomosis area, caused by taking into account the systemic arterial haemoglobin saturation index.
