Abstract: We evaluated the influence of hypoxic hypoxia on lactate, creatinine and urea concentrations in the amniotic fluid (AF) of rabbits on 27-28th day of pregnancy. Rabbits were randomly sudivided into two groups: experimental (n=9) and control (n=6). Rabbits of experimental groups were placed in a hypoxic chamber containing 10±2% oxygen and 90±2% nitrogen for 1 h and then were euthanized, AF was extracted from the amniotic sacs via disposable syringe. Acute hypoxic hypoxia had no effect on the AF volume, increased (1.4-fold) lactate, (1.3-fold) creatinine and (1.1-fold) urea concentrations in AF. In contrast to animals of the control group, lactate concentration in the groups with hypoxic hypoxia correlated with the creatinine (r=0.71, p<0.0001, n=35) and urea concentrations in the AF (r=0.81, p<0.0001, n=35). These results suggest that acute hypoxic hypoxia in late pregnancy causes changes in the biochemical composition of AF; these changes are characterized by high lactate concentrations, and the fetus and uterus can be the source of increased lactate level in AF.
