On the other hand, if the cord is twisted two or three times, it may cause the cord to jam or blood flow to stop as the baby descends, causing the baby's life to be troubled. Although a detailed ultrasound can sometimes be detected in the first trimester, it is usually recognized in the last trimester of pregnancy. This problem, which is mostly understood during labor; As the baby advances in the birth canal, it may cause birth pains and contractions and decrease the baby's heartbeat. However, this often does not cause permanent damage to the baby.Cord Knotting The core cord acts as an elastic tube swinging in the liquid in the cavity. The knot movement of the cord from anywhere in the baby is called the düğüm real knot on the cord.. Some babies may be born with a real knot on the umbilical cord. In this case, which is seen at an average rate of 1%, the decrease in blood flow in the cord may endanger the baby's life.
In addition, there is a situation called düğüm false knot on the cord;; this is a varicose-like dilation of the vessels within the cord. Here, the cord becomes so twisted in a certain region that it is seen as a knot. This is because one of the vessels is longer. This vein may take a knot-shaped appearance by twisting its neck to match the length of the cord. False nodes generally do not cause a problem, while the actual node in the cord can cause infant losses of up to 6%. True nodes are more common, especially in identical twins in a single amniotic sac. Actual nodes cannot be detected on ultrasound in most cases. When the baby's heart rate decreases during ultrasound, the possibility of cord knotting is considered (although other anomalies related to the cord may lead to similar findings), it cannot be definitively diagnosed. The exact diagnosis can usually be made at birth. However, if ultrasound is detected in the cord, it is essential to perform the cesarean section.Cord ProlapseWhen the water bladder is opened at birth, it is called cord hanging. 0.5% of cord sagging is most commonly seen in fetal development disorders. Breech and lateral incidence are among the important risk factors. This anomaly is more common in premature births or when the baby is very small. Risk factors include multiple births of the mother, multiple pregnancies, premature opening of the water sac, longer cord than normal, or excess amniotic fluid. Diagnosis is made by hand sensing the cord during the examination or by visual observation outside the vagina. When the cord hangs, the uterine contractions may deteriorate, leading to the death of the baby. If the baby is alive when the condition is understood, it is necessary to give birth immediately by cesarean section. Cord JamThe compression of the umbilical cord between the baby's arms and legs, or between the baby and the placenta, and its inability to move freely, is called cord compression. This is very common, especially in cases where the cord is short, entangled in the neck or has a real knot. Lack of amniotic fluid or large baby also poses a risk for cord jams. The baby's heart rate normally ranges from 120 to 160 per minute. In cases where the speed drops below 100 beats per minute and does not return to normal within a few minutes, some precautions should be taken, such as returning to the left side of the expectant mother and giving oxygen. In general, babies easily get rid of this situation. However, caesarean section is seen as the most appropriate delivery method in order not to put the baby at risk.Short CordIf the length of the umbilical cord is shorter than 35 cm, there will be ord cord shortness ”. This may prevent the infant from entering the birth canal and may also delay the passage of the baby through the birth canal. Most of the deliveries go to an emergency caesarean section because the short cord can lead to delayed labor and endanger the baby's life. Umbilical cord shortening may also cause premature separation of the placenta; this means that it increases the risk of premature birth.
