摘要：
FIELD: medicine.SUBSTANCE: invention can be used for the purpose of predicting early postoperative (for the first 6 postoperative days) complications in the form of organ dysfunctions in the patients following coronary artery bypass graft surgery. To this effect, within 25-35 minutes upon the beginning of the bypass procedure, the following central haemodynamics values are measured: blood pressure (BP) and central venous pressure (CVP), homeostasis including the blood lactate concentration (Lact), oxygen partial pressure in venous (pvO2) and arterial blood (paO2), and the packed cell volume (Ht). Besides, the time of the bypass (t1), the time of the aortic compression (t2) and the patients age are determined, and a discriminator is derived by formula: D=3.321+(0.006)*AP+(0.011)*CVP+(1.030)*Lact+(-0.009)*paO2+(0.005)*pvO2+(-0.124)*Ht+(-0.023)*age+(0.014)*t1+(-0.019)*t2. If D<-0.6, the low risk of early postoperative organ dysfunctions is stated. The values D>0.6 enable stating the high risk of the organ dysfunctions. The value falling within the range of -0.6
