As a mother- to-be, you probably think about the little one in your womb a lot, don't you? Are they okay, are they getting enough food and oxygen, are they okay? So, today we're going to talk about something that often scares mothers a little, but is actually not that common. That is the formation of a knot in the baby's umbilical cord, especially a condition called a 'true knot' . Even if you feel a little nervous when you hear this name, don't worry. Let's talk about this in detail and simply.
What is a knot in the umbilical cord? Is it like a shoelace?
Simply put, yes. Just like your shoelaces can get tangled, your baby's umbilical cord can get tangled. These knots can form as your baby moves around in the womb. But most of the time, these little knots don't cause any major problems for your baby. Plus, they usually come untied on their own.
There's a reason for this. Inside the umbilical cord, there's a gel-like substance called 'Wharton's jelly.' This is what protects the umbilical cord. So even if a small knot forms, this gel won't let it get tight. Isn't it amazing?
Why is it called a 'True Knot'?
However, in rare cases, this knot can become a little tight. Doctors call a knot that is so tight a 'True Knot' . Unlike the small knots mentioned earlier, this one does not come undone easily. When this knot becomes tight, it can block the flow of oxygen and nutrients to the baby through the umbilical cord. It's like a water pipe that gets blocked and the water flow is reduced. This can cause complications during pregnancy and during delivery. Because the baby doesn't get the things it needs to survive.
But remember, these so-called 'True Knots' are very rare. That means they don't happen very often. However, in most cases, the baby is born healthy. So, it's better not to panic in advance, right?
What is the umbilical cord? How is it important for the baby?
Do you know how valuable the umbilical cord is to a baby? It's like the connection between the baby and the mother's placenta. Everything the baby needs to grow in the womb is provided through this umbilical cord.
- This is what carries oxygen from the placenta to the baby.
- This also carries the nutrients the baby needs.
- Also, it is this umbilical cord that helps carry waste products produced in the baby's body back to the placenta and out of the mother's body.
So you understand that the umbilical cord is like a baby's lifeline.
How common are these knots really?
Many mothers are scared when they hear about this, so it's good to know how common it is. On average, about 1 in 100 pregnancies will have some kind of knot in the umbilical cord. But not all of those knots are the 'true knot' we've been talking about. In fact, 'true knots' occur in less than 1% of all pregnancies. That's very rare.
Why do these umbilical cords get tangled? Is it anyone's fault?
Most of the time, even doctors can't say exactly why these lumps form. But they do know that there are certain factors that can increase the risk. Also, there are times when these lumps just form when the baby is moving around in the womb, rolling around. It's a very natural thing.
Another thing is that sometimes a knot can become even tighter as the baby approaches and due to the pressure from labor and delivery.
The most important thing is to understand that this kind of knot is not because of anything you did or because of your fault. Don't worry about it.
Small, uncomplicated knots are usually nothing to worry about. However, problems can arise if the knot becomes tight and becomes a 'true knot'. This can cause pressure on the umbilical cord and cut off oxygen to the baby. Your doctor will be on the lookout for this, especially if you have any risk factors.
Who is more likely to develop this type of lump? (Risk factors)
Sometimes these tumors can develop without any risk factors. However, doctors point out that this risk may be slightly increased in people with the following factors:
- If the baby is growing slowly: That is, if the baby is small for gestational age.
- If the umbilical cord is too long: If the umbilical cord is longer than normal, there is a greater chance of knots forming.
- If you are carrying monoamniotic twins: That is, if there are two twins in the same amniotic sac, there is a greater chance that the umbilical cords will become entangled and tangled as they move around.
- If there is too much amniotic fluid: This is called ``polyhydramnios.`` The more fluid, the more room the baby has to move around, which can cause knots.
- If you have given birth to two or more children before (multiparity).
- If you are over 35 years old.
- If you feel a decrease in fetal movement during the third trimester, this can sometimes be a reason to check for a knot.
These are the main risk factors that have been identified.
What happens if there is a knot in the umbilical cord?
The best way to think about a 'True Knot' is to think about what happens when you tie a knot in a garden hose. The knot prevents the water from flowing properly, right? That's how it is with this one. The baby is deprived of the oxygen and nutrients it needs to survive. This can affect the baby's growth and health.
What complications can a baby have from a 'True Knot'?
True knots in the umbilical cord can cause serious complications for the baby, as they can cut off the baby's oxygen supply. The long-term effects depend on how tight the knot is.
- If the knot is too tight: The baby may suffer from severe hypoxia. Sometimes, it can be life-threatening.
- If the knot is slightly loose: Even if the oxygen supply is somewhat impaired (`mild hypoxia`), there may be no long-term damage.
Some long-term effects may be:
- Cerebral Palsy: A condition caused by a lack of oxygen to the brain.
- Hypoxic-ischemic encephalopathy (HIE): This is also brain damage caused by a decrease in oxygen and blood supply to the brain.
- Brain damage.
- Developmental or cognitive delays.
These are scary to hear. But remember, these things happen very rarely.
Is it possible to lose a baby due to a knot like this? (Stillbirth)
Yes, sadly, in some very rare cases, a 'true knot' can result in stillbirth. However, most pregnancies and births end in a healthy baby. So don't worry too much about it.
How do we know if there is a 'True Knot' in the umbilical cord?
Most of the time, you don't know you have a 'true knot' in the umbilical cord until after the baby is born. However, some people may feel less baby movement during the third trimester of pregnancy. This is a risk factor for a 'true knot'. That's why you should tell your doctor right away if you feel less baby movement.
Sometimes, doctors can detect a 'true knot' during pregnancy through an ultrasound if they notice a change in the baby's heart rate or movement pattern. However, these knots are very difficult to detect with an ultrasound during pregnancy. That's why they are often detected after the baby is born.
Sometimes, a doctor may suspect a knot if there is a sudden change in the baby's heart rate during labor and delivery. If this happens, the doctor will need to act quickly and decide whether it is still safe to deliver the baby vaginally.
What are the doctors doing about this?
Even if a knot is found, doctors cannot untie it. The most important thing in managing a 'true knot' is to be aware of the risk factors and be vigilant for complications if someone has a risk factor.
- If a lump is found on an ultrasound before the baby is born: Your doctor will take a closer look at your pregnancy, especially in the third trimester. This may include additional ultrasounds, Doppler studies (a scan that looks at the blood flow in the umbilical cord), and regular checkups to check the baby's growth and movements.
- If you notice a knot during labor: If this is due to changes in the baby's heart rate, you should monitor the baby closely for fetal distress. If there is a 'true knot', the knot may become tighter due to contractions during labor. That's why doctors pay close attention to the baby's heart rate as labor progresses. If the baby seems to be in distress or is getting oxygen-deprived, an emergency C-section may be necessary.
Although this may sound scary, 'true knots' are very rare. However, doctors do their best to prevent them from causing permanent damage.
So what are the most important things we need to remember about this? (Take-Home Message)
Okay, so let's remind you of some of the most important things we've talked about.
- True Knots are Very Rare: While it may be scary to hear about umbilical cord knots, serious 'true knots' are actually very rare.
- Babies are often born healthy: Even if there is a knot, in most cases babies are born healthy without any complications.
- It's not your fault: A knot didn't form because of anything you did. Don't worry about it.
- Keep an eye on your baby's movements: If you feel less baby movement, especially towards the end of your pregnancy, tell your doctor.
- Talk to your doctor: If you have any questions or concerns about this, talk to your doctor. They will provide you with the explanations and support you need.
Pregnancy is a time of great expectations, but also of little fears. Instead of worrying too much about the umbilical cord, focus on your health and happiness. If your doctor says that your pregnancy is going well and your baby is growing well, then the chances of this kind of complication occurring are very low.
