[Analysis of lochial acid-base equilibrium in an uncomplicated course of the postpartum period and in endometritis].

Lochial acid-base status was analyzed in 45 puerperants in whom the postpartum period ran an uncomplicated course or was complicated by endometritis. The normal course of the puerperium is associated with the development of metabolic acidosis in the uterine cavity, and this acidosis is completely compensated for at the expense of gas alkalosis. In slight endometritis metabolic acidosis augments, and grave endometritis is associated with the development of marked acidosis at the expense of the development of tissue hypoxia in the presence of metabolic acidosis.
