To the casuistry of childbirth with fused twins

On April 13, 1895, at 5 o'clock in the morning, a peasant woman, 23 years old, was admitted to the clinic with labor pains. When asked, it turned out that labor began at 2 am on April 13, that she was pregnant in the 4th section; the previous labor was completely normal; the last regulation was at the end of July. The study produced the following: The pelvis is almost normal: dis. sp. 24.5, dis. cr. 27, intertr. 31, conj. ext. 19. The uterus is ovoid. The heartbeat of the fetus is heard on the right below the navel, 132 beats per minute. Full throat opening. The bubble is intact. Head to be presented. The arrow-shaped suture in the right oblique size of the pelvis; a small fontanel is felt to the right posteriorly. The second position was established, the rear view. As soon as the women in labor had time to take a bath, the waters passed. The head, which was still in the entrance of the pelvis, began to descend little by little into the cavity. At 8 a.m. 40 m, that is, after 3 hours with more than a rupture of the bladder, the head began to press on the perineum, which lasted more than half an hour, and finally at 9 o'clock. 15 minutes. the head has erupted. The born head, having made a slight movement first to the left and then to the right, turned its face towards the symphysis. At this moment, the forward movement of the fetus stopped.
