METHOD FOR PREDICTING MODERATE AND PRONOUNCED ERYTHROCYTE LYSIS FOLLOWING CARDIOPULMONARY BYPASS SURGERY Russian patent published in 2015 - IPC G01N33/49 

FIELD: medicine.

SUBSTANCE: patient's pre-operative health is assessed with taking into account the presence/absence of pulmonary and renal diseases, erythrocyte Rh C-antigen, hyperinosemia of more than 4 g/l and erythrocyte count of 4.81×10¹²/l and less; a haemolytic perfusion risk (HPR) is calculated by formula HPR=(6.38×X_pulm+8.93×X_hyp+3.32×X_Er)-(4.10×X_ren+2.95×X_C), wherein the numerical values 6.38; 8.93; 3.32; 4.10; 2.95 are coefficients; X_pulm is the presence (1)/absence (0) of pulmonary diseases; X_hyp is the presence (1)/absence (0) of pre-operative hyperinosemia; X_Er is the presence (1)/absence (0) of the pre-operative erythrocyte count 4.81×10¹²/l and less; X_ren is the presence (1)/absence (0) of renal diseases; X_C is the presence (1)/absence (0) of erythrocyte Rh C-antigen; if HPR>6.1, pronounced erythrocyte lysis is predicted; HPR<6.1 shows moderate erythrocyte lysis.

EFFECT: method enables increasing accuracy, information value and accessibility of the erythrocyte lysis prediction.
