Umbilical cord prolapse should always be considered a possibility when there is a sudden decrease in fetal heart rate or variable decelerations, particularly after the rupture of membranes. With overt prolapses, the diagnosis can be confirmed if the cord can be felt on vaginal examination.
Umbilical cord prolapse occurs when the umbilical cord comes out of the uterus with or before the presenting part of the fetus. Umbilical cord prolapse should always be considered a possibility when there is a sudden decrease in fetal heart rate or variable decelerations, particularly after the rupture of membranes. With overt prolapses, the ...
On occasion, with the rupture of membranes, particularly if the head is not engaged, the umbilical cord may prolapse. A cord prolapse is an obstetrical emergency, as the descending head may block fetal-placental circulation. Once the membranes are ruptured, bacteria may ascend and could lead to amnionitis and fetal infection.
These vessels may be from either a velamentous insertion of the umbilical cord or may be joining an accessory (succenturiate) placental lobe to the main disk of the placenta. If these fetal vessels rupture the bleeding is from the fetoplacental circulation, and fetal exsanguination will rapidly occur, leading to fetal death. It is thought that ...
The vessels are hence normally protected by Wharton's jelly, which prevents rupture during pregnancy and labor. [10] In velamentous cord insertion, the vessels of the umbilical cord are improperly inserted in the chorioamniotic membrane, and hence the vessels traverse between the amnion and the chorion towards the placenta.
Waiting at least two minutes before clamping the umbilical cord of a premature baby may reduce the risk of death by at least a third, new research suggests.
1. The baby may turn to a breech position, making birth more difficult if the membranes are ruptured before head engagement. [5] 2. There is an increased risk of umbilical cord prolapse. [5] 3. There is an increased risk of infection if there is a prolonged time between rupture and birth. [5]
Low levels of amniotic fluid due to mid-trimester or previable PPROM (before 24 weeks) can result in fetal deformity (e.g. Potter-like facies), limb contractures, pulmonary hypoplasia (underdeveloped lungs), [11] infection (especially if the mother is colonized by group B streptococcus or bacterial vaginosis), prolapsed umbilical cord or ...
