The oxygen metabolism was studied up in patients, operated on for gastrointestinal haemorrhage after conduction of an urgent measures for hypovolemia elimination. While favourable course of an early postoperative period the systoles rate (SR) was less than 116 in a minute. Sensitivity of the symptom (frequency of the symptom revealed in the patients of this group) was 94.54%, specificity (the absence of the symptom in the patients of other groups)--53.31%. Constant tachycardia (SR more than 116 in a minute) is a prognostic symptom of exitus lethalis. Its sensitivity is 100%, specificity--83.14%. Moderate loss of xi-potential of erythrocytes is complementary symptom, permitting exitus lethalis prognostication conduction. The increase of ratio of lactic acid and piruvate contents in the blood up to more than 5.25 conventional units is characteristically for the complicated but favourable for life an early postoperative course. Sensitivity of the feature is 91.17%, specificity--60.29%.
