Uterine perfusion, the po 2 in maternal ear capillary blood, the po 2 and pH in portio blood, and the po 2 PH, BE and pco 2 in blood from the foetal scalp were investigated in 50 normal women in the 36th or subsequent weeks of pregnancy, women were given either oxygen ventilation, xanthinol nicotinate (Complaminr`), or oxygen ventilation in conjunction with this drug. Uterine perfusion decreased in all groups, the greatest fall being in the group ventilated with 100% oxygen. The po 2 rose in all groups given oxygen. The smallest rise was noted in foetal blood. The remaining changes in blood chemistry were very small.
