Blood Acid-Balance Balance During Pregnancy

Abstract

Relevance and objectives: to study and analyze the indicators of the acid - base state of the blood in the second and third trimesters of pregnancy, which proceeds without complications. A study of arterial and venous blood was carried out in 80 patients with uncomplicated pregnancy and 32 non-pregnant women to determine the parameters of the acid-base balance of blood on a gas analyzer. It was found that in the blood of women with a physiological course of pregnancy there is an accumulation of acidic metabolic products, a decrease in alkaline blood reserves - carbonate and protein buffers. The most significant fluctuations in the indicators of the acid-base state of the blood were observed in the third trimester of pregnancy. But all the observed changes were compensated due to the absence of a shift in blood pH
