Condition of microcirculation in parturients who have undergone moderate pathological blood loss

Abstract

The state of conjunctival microcirculation and blood coagulation was studied in parturients who underwent pathological blood loss, the amount of which did not exceed 20% of the proper BCC and ranged from 500 to 1000 ml.Thirty-six parturient women were under observation; 20 of them constituted the study group and 16 the control one. The study group comprised women aged 18 to 32 years, of whom 12 first-born women and 8 second-born women were followed-up. The cause of bleeding in 13 women giving birth was uterine hypotonicity, in 2 women - a tight placenta attachment, in one - a detachment of the normally located placenta, in one - a placental defect, in 2 - deep vaginal ruptures. One woman in labor had a combination of tight placenta attachment and uterine hypotension. The amount of blood loss ranged from 400 to 800 ml in 17 women. In 3 parturients it reached 1000 ml. Infusion and transfusion therapy was administered in a timely manner and in sufficient volume. The Hb level 5-6 days after delivery was 1.640.15 mmol/l, in the control group - 1.740.14 mmol/l.
