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]
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.
Before 24 weeks the fetus is still developing its organs, and the amniotic fluid is important for protecting the fetus against infection, physical impact, and for preventing the umbilical cord from becoming compressed. It also allows for fetal movement and breathing that is necessary for the development of the lungs, chest, and bones. [8]
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 ...
umbilical cord accidents. Prolapsed umbilical cord – Prolapse of the umbilical cord happens when the foetus is not in a correct position in the pelvis. Membranes rupture and the cord is pushed out through the cervix. When the fetus pushes on the cervix, the cord is compressed and blocks blood and oxygen flow to the fetus.
Umbilical cord prolapse occurs when the umbilical cord comes out of the uterus with or before the presenting part of the fetus. It is a relatively rare condition and occurs in fewer than 1% of pregnancies. Cord prolapse is more common in women who have had rupture of their amniotic sac.
Risk factors include pulling on the umbilical cord or pushing on the top of the uterus before the placenta has detached. [1] Other risk factors include uterine atony, placenta previa, and connective tissue disorders. [1] Diagnosis is by seeing the inside of the uterus either in or coming out of the vagina. [2] [6]
Umbilical cord compression can result from, for example, entanglement of the cord, [16] a knot in the cord, [16] or a nuchal cord, [16] (which is the wrapping of the umbilical cord around the fetal neck) [17] but these conditions do not always cause obstruction of fetal circulation.
