Previa and prolapsed cord

Previa and prolapsed cord. There are, in the absence of contact zone (lateral position of the fetus, breech him narrow pelvis). Previa and especially prolapsed cord dangerous for the fetus because of the possibility of occurrence of fetal asphyxia. With cephalic presentation and prolapsed umbilical cord is necessary to try to tuck it behind the head, and the last capture using skin-head forceps. On failure to complete delivery should be by caesarean section. A full disclosure of the cervix and mobile fruit produce external-internal rotation followed by extraction of the fetus. When breech pressing prolapsed umbilical cord loops is less of a danger to the fetus, as the soft end of the pelvic squeezes smaller umbilical vessels. By extraction of the fetus for pelvic end begin only at the outbreak of asphyxia.
