RHEOLOGICAL PROPERTIES OF BLOOD AT PATIENTS WITH BOWEL OBSTRUCTION OF TUMORAL GENESIS IN THE EARLY POSTOPERATIVE PERIOD

Introduction. Microcirculation plays an important role in early postoperative period in colorectal cancer patients. At the same time the question connected with studying of rheological properties of blood as one of microcirculation indicators in literature it studied insufficiently.

Materials and methods. We studied rheological properties of blood in 30 patients operated for bowel obstruction caused by right colon cancer. 17 (56,7 %) patients were male, 13 (43,3 %) – female. Average age was 57 ± 3 years. Time from the moment of manifestation of the first clinical signs before admission to a hospital and the beginnings of carrying out medical and diagnostic actions was 12 ± 0,5 h. The stage of a disease was T3N0–1M0. The group of comparison consisted of 20 healthy volunteers of the same age. Changes of a rheology of blood were measured by means of the accounting of viscosity of blood, change of an index of deformation and aggregation of erythrocytes. Studying of viscosity of blood was carried out by means of the rotational viscometer at shift speeds: 200; 100; 150; 50 and 20 MPas. Measures were conducted at the time of receipt, on the first, third, fifth, seventh and tenth postoperative day.

Results. In patients with bowel impassability at the time of receipt the increase in indicators of viscosity of blood is noted at all speeds of the shift, analyzed indicators increase by the third postoperative day, decrease on the seventh and are partially restored for the tenth postoperative days. Complications developed in 16,6 % of cases, in all cases – pneumonia. By comparison of the obtained laboratory data to a clinical picture it is established that complications developed on 3–5th postoperative days.
