Umbilical cord: everything you need to know

The umbilical cord

The umbilical cord may be one of the most important parts of human development, yet many people don’t know much about it.

It’s the connection that transfers nutrients and oxygen to the fetus during pregnancy, and once the baby is born, it’s cut to separate the newborn from the placenta.

But what else should we know about this vital cord? In this blog post, we’ll explore everything you need to know about the umbilical cord and its role in pregnancy and childbirth.

We’ll cover the functions of the umbilical cord, including the different types of cells that make it up and the various components that help it function.

We’ll also discuss the importance of proper cord care, especially in the moments after birth. Additionally, we’ll dive into some of the more common disorders and issues that can arise with the umbilical cord, such as cord prolapse and nuchal cord.

Whether you’re a soon-to-be parent or simply curious about the intricacies of the umbilical cord, you will enjoy this article.

1. Structure of the umbilical cord

The umbilical cord is a vital structure that connects the developing fetus to the placenta in utero.

It provides a pathway for oxygen and nutrients to travel from the mother to the fetus, and for waste products to be removed from the fetus.

The structure of the umbilical cord consists of two arteries and one vein encased in a gelatinous substance called Wharton’s jelly. The arteries carry deoxygenated blood and waste products away from the fetus, while the vein carries oxygenated blood and nutrients to the fetus.

The umbilical cord is typically around 55 cm long and 2 cm thick at full term, although variations in length and thickness can occur. Understanding the structure of the umbilical cord is essential for obstetricians, midwives, and healthcare professionals involved in prenatal care and delivery.

2. Developmental function of the cord

The umbilical cord plays a critical role in fetal development during pregnancy. One of its primary functions is to provide oxygen and nutrients to the developing fetus.

The cord contains two arteries and one vein, which work together to transport blood and nutrients to the placenta. The placenta is responsible for filtering out waste products and supplying the developing fetus with the necessary nutrients and oxygen.

In addition to providing nutrients, the umbilical cord also plays a crucial role in removing waste products from the fetus. The cord serves as a conduit for the removal of carbon dioxide and other waste materials from the developing fetus, which are then transported back to the mother’s bloodstream for disposal.

Therefore, the developmental function of the umbilical cord is crucial to the health and survival of the developing fetus during pregnancy.

3. Importance of cord blood stem cells

Cord blood stem cells have become an increasingly important topic in the field of medicine.

Stem cells are unspecialized cells that have the ability to develop into different types of cells, tissues, and organs in the body. Cord blood stem cells are collected from the umbilical cord and placenta following childbirth. These cells have the unique ability to grow and regenerate, and they can be used to treat a range of diseases and conditions, including certain types of cancer, blood disorders, and genetic diseases.

One of the key advantages of cord blood stem cells is that they are a perfect match for the child from whom they were collected, which greatly reduces the risk of rejection when used in a transplant. In addition, cord blood stem cells are less likely to carry infectious diseases compared to other sources of stem cells, making them a safer option for transplantation.

Given their potential to treat a wide range of diseases and conditions, the importance of cord blood stem cells cannot be overstated.

4. Potential for cord blood banking

Cord blood banking is a medical practice that involves collecting and storing the blood from a newborn baby’s umbilical cord.

This practice has the potential to be a valuable source of stem cells for medical treatment in the future. The stem cells found in umbilical cord blood can develop into various types of cells, such as red and white blood cells, platelets, and even nerve cells. These cells have the potential to treat a range of medical conditions, including genetic diseases, blood disorders, and some types of cancer.

However, it is important to note that the chances of using these stored cells for treatment are relatively low, and the cost of cord blood banking can be high. It is recommended that parents consult with a healthcare provider to discuss the potential benefits and risks of cord blood banking before making a decision.

5. Risks associated with cord prolapse

Cord prolapse is a rare but serious obstetric emergency in which the umbilical cord descends from the uterus into the birth canal before the baby.

This can lead to compression or occlusion of the cord, which can result in fetal hypoxia and possible death. If you suspect that a cord prolapse has occurred, it is essential to act quickly and obtain immediate medical attention.

However, cord prolapse is preventable with careful management during labor, including early detection of risk factors such as breech presentation, premature rupture of membranes, and induction of labor.

It is important for healthcare providers to be aware of the risks associated with cord prolapse and to have the knowledge and skills necessary to manage this emergency situation promptly and effectively.

6. Umbilical cord knots and complications

Umbilical cord knots and complications are a rare but serious concern during pregnancy. The umbilical cord is responsible for delivering oxygen and nutrients to the developing fetus, and any issues with the cord can impact fetal growth and development.

Umbilical cord knots can occur when the fetus moves around in the womb and twists the cord, causing it to knot or tangle.

While most knots are harmless, there is a risk of complications if the knot becomes too tight and restricts blood flow. This can result in fetal distress or even stillbirth. Other complications of the umbilical cord can include prolapse, where the cord drops into the birth canal before the baby, or nuchal cords, where the cord becomes wrapped around the baby’s neck.

It is important for expectant mothers to receive regular prenatal care and for healthcare providers to monitor the umbilical cord for any potential complications during pregnancy and delivery.

7. Delayed cord clamping benefits

Delayed cord clamping is a practice that involves waiting for several minutes after the baby is born before cutting the umbilical cord.

This practice has gained popularity in recent years due to the numerous benefits it offers to the newborn. Delayed cord clamping allows the baby to receive more blood, and therefore, more oxygen and nutrients from the placenta.

This extra blood can increase the baby’s iron stores, which is essential for healthy development. Studies have shown that delayed cord clamping also reduces the risk of anemia, which can occur in the first year of life.

Additionally, delayed cord clamping has been linked to a lower risk of respiratory distress syndrome, a common condition in premature babies.

Overall, delayed cord clamping is a simple and effective way to promote the health and well-being of newborns.

8. Cord blood donation process

Cord blood donation is a process of collecting and storing cord blood from a baby’s umbilical cord after birth.

The process of cord blood donation is safe, painless, and non-invasive. It can be done in both public and private cord blood banks. Before the donation process, the donor mother has to go through a screening process to ensure that she and the baby are healthy and eligible for donation.

The screening includes a medical history review and blood tests. During the donation process, the umbilical cord is clamped and the blood is collected using a sterile needle and a bag.

The entire process takes about 10-15 minutes, and it does not affect the delivery or the health of the mother or the baby. Once collected, the cord blood is shipped to the cord blood bank for processing, testing, and storage.

Cord blood donation is a noble act that can potentially save a life in the future.

9. Cord care after birth

Caring for the umbilical cord after birth is an essential part of newborn care. The umbilical cord stump usually drops off within the first two weeks, leaving a small wound that requires careful attention to prevent infection.

To care for the stump, it is essential to keep it clean and dry at all times. Newborns should be bathed using sponge baths until the stump falls off completely.

It is important to avoid getting the stump wet or submerging the baby in water until it is healed. Clean the stump with warm water and mild soap and dry it gently using a soft towel.

Fold the diaper below the stump to keep it dry and avoid rubbing against it. Keep an eye on the stump for signs of infection, such as redness, swelling, discharge, or a foul odor. Notify your healthcare provider immediately if you notice any of these signs.

With proper care, the umbilical cord stump will heal quickly, and your baby will be on their way to a healthy start.

10. Future research on cord function

As research on umbilical cords continues to evolve, future studies will likely focus on a variety of areas related to cord function.

One key area of interest is the role of the umbilical cord in fetal development, including how it supports the growth and nutrition of the fetus.

Researchers may also investigate the potential for using cord blood and tissue in regenerative medicine, as these materials contain valuable stem cells that can be used to treat a range of medical conditions.

Additionally, studies may explore the potential for using umbilical cord blood and tissue to develop new treatments for diseases such as cancer, diabetes, and autoimmune disorders.

As our understanding of the umbilical cord and its functions continues to grow, it is likely that new avenues for research and treatment will emerge, offering hope for improved health outcomes for patients around the world.

In conclusion, the umbilical cord is a vital element in prenatal development, connecting the fetus to the placenta and providing it with the necessary oxygen and nutrients.

Understanding the structure, function, and potential issues related to the umbilical cord can help expectant mothers and healthcare providers ensure the best possible outcomes for both the mother and baby.

As with any medical issue, it’s essential to speak with a qualified healthcare provider if you have concerns or questions about the umbilical cord or any aspect of pregnancy.
