Abstract
The concentration of HCO −3 , pH, pO2, sO2, and pCO2 were measured in the total umbilical blood of neonates born in January–February (n = 169) and June–July (n = 172). The former group displayed higher values of pH, pO2, and sO2, whereas pCO2 and the concentration of HCO −3 were higher in the latter group. There was a 70–80% coincidence of the variants in both groups (the regions of statistical transgressions); seasonal factors were responsible for 20–30% of the differences.
