METHOD FOR PREDICTING THE NEED FOR ALLOGENEIC ERYTHROCYTE-CONTAINING BLOOD COMPONENTS DURING SURGICAL CORRECTION OF VALVULAR PATHOLOGY IN THE INTRAOPERATIVE AND EARLY POSTOPERATIVE PERIODS IN ADULT PATIENTS Russian patent published in 2018 - IPC G01N33/48 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to transfusiology, and is intended for use in medical institutions when predicting need for allogeneic erythrocyte-containing blood components in the intraoperative and early postoperative periods with surgical correction of valvular pathology in adult patients. Essence of the method: on the eve of the operational day, on the basis of the plan of operations, when identifying the factors influencing the transfusion of allogeneic erythrocyte-containing blood components in the patient, they are assigned prognostic factors, namely to: valve prosthetics, with the exception of aortic valve, – 2 points, aortic valve prosthetics – 3 points, valve plastic – 1 point, combination of different types of surgical intervention – highest score, increased by 1 unit, operations with artificial circulation – 1 point, age of the patient over 70 years old – 1 point, reoperation of the heart and aorta – 1 point, preoperative hemoglobin level 131–140 g/l – 1 point, preoperative hemoglobin level 121–130 g/l – 2 points, preoperative hemoglobin level 110–120 g/l – 3 points, preoperative hemoglobin level less than 110 g/l – 4 points, patient weight less than 70 kg – 1 point and with the sum of prognostic coefficients 1–3 points predict a minimal requirement and allogeneic erythrocyte-containing blood components on this patient do not reserve; with the sum of prognostic coefficients 4-5 points predict the need for a single dose of allogeneic erythrocyte-containing blood components; with the sum of prognostic factors of 6–8 points predict the need for two doses of allogeneic erythrocyte-containing blood components; at the sum of prognostic factors of 9 points and more predict the need for more than two doses of allogeneic erythrocyte-containing blood components.

EFFECT: proposed invention is aimed at optimizing the operation of the transfusiology unit (blood transfusion unit) to form a stock of allogeneic erythrocyte-containing blood components by predicting the need for them in the intraoperative and early postoperative periods with surgical correction of valvular pathology in adult patients.
