Umbilical cord prolapse is when the umbilical cord comes out of the uterus with or before the presenting part of the baby. [2] The concern with cord prolapse is that pressure on the cord from the baby will compromise blood flow to the baby. [2] It usually occurs during labor but can occur anytime after the rupture of membranes. [1] [5]
Nuchal cord, when the umbilical cord is (tightly) around the neck of the fetus [2] Entanglement of the cord [2] Knot in the cord [2] Cord prolapse, where the umbilical cord exits the birth canal before the baby, which can cause cord compression. [3] As a complication of oligohydramnios in which there is insufficient amniotic fluid
Intrauterine hypoxia (also known as fetal hypoxia) occurs when the fetus is deprived of an adequate supply of oxygen.It may be due to a variety of reasons such as prolapse or occlusion of the umbilical cord, placental infarction, maternal diabetes (prepregnancy or gestational diabetes) [1] and maternal smoking.
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 ...
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 ...
Further analysis suggested that waiting two or more minutes to clamp the cord had a 91% probability of being the best treatment to prevent death shortly after birth in premature babies.
Amnioinfusion is a method in which isotonic fluid is instilled into the uterine cavity.. It was introduced in the 1960s as a means of terminating pregnancy and inducing labor in intrauterine death, but is currently used as a treatment in order to correct fetal heart rate changes caused by umbilical cord compression, indicated by variable decelerations seen on fetal heart rate monitoring.
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. [1] [11] Without Wharton's jelly protecting the vessels, the exposed vessels are susceptible to compression and rupture. [1] [9]
