[Characteristics of the changes in the concentration of 2,3-diphosphoglycerate in heart surgery patients].
Changes in 2,3-DPG level have been studied in cardiosurgical patients. It has been shown that 2,3-DPG concentration increase, as a moderately fast mechanism in a common model of tissue pO2 regulation, is observed in almost half of patients with acquired heart valve defects. An increase in 2,3-DPG level and P50 value leading to a decrease in hemoglobin affinity to oxygen has been found in one third of patients. It has been established that 2,3-DPG level and P50 value are, as a rule, normal in patients with mitral stenosis, acyanotic congenital heart valve defects and ischemic heart disease. In a number of patients with mitral stenosis an increased Hb concentration, as a slow mechanism of hypoxia compensation in the model of tissue pO2 regulation, is a prevailing mechanism of adaptation to hypoxia.
