When a newborn baby is born, their body is adjusting to life outside the womb, and some common conditions can occur as a result. One of the most common conditions seen in newborns is jaundice, which causes a yellowing of the skin and eyes. Jaundice occurs when there is too much bilirubin in the blood, a yellow compound that is produced when red blood cells break down.
To treat jaundice in newborns, one of the most effective and commonly used methods is phototherapy. But what exactly is phototherapy, how does it work, and why is it so important in treating jaundice? In this article, we will answer these questions and explain everything you need to know about phototherapy for newborns.
We will cover how phototherapy works, when it is necessary, its benefits and risks, and what parents can expect during the process. This guide will help parents better understand how phototherapy is used to help newborns recover from jaundice and ensure their well-being in the early days of life.
What is Phototherapy?
Phototherapy is a treatment that uses light to reduce the levels of bilirubin in a newborn’s blood. Bilirubin is a waste product that results from the breakdown of red blood cells. Normally, a baby’s liver processes bilirubin and removes it from the body, but in newborns, especially in premature babies, the liver may not be fully developed yet, leading to an accumulation of bilirubin.
Phototherapy works by using special lights that help the baby’s skin break down the excess bilirubin more quickly. This light is absorbed through the skin, which helps convert the bilirubin into a form that can be more easily eliminated from the body through the baby’s urine and stool.
Why is Phototherapy Used?
Phototherapy is mainly used to treat jaundice in newborns. Jaundice is a common condition in newborns, affecting about 60% of full-term babies and even more premature babies. While jaundice is usually harmless and resolves on its own as the baby’s liver matures, in some cases, bilirubin levels can become dangerously high and need medical treatment.
If left untreated, high bilirubin levels can lead to serious complications such as brain damage, known as kernicterus. Phototherapy helps prevent these complications by reducing the bilirubin levels and allowing the baby to recover safely.
How Does Phototherapy Work?
Phototherapy works by using light to break down bilirubin in the baby’s skin. The light used in phototherapy is typically blue or white light, which is absorbed by the baby’s skin. This light breaks down the bilirubin into a water-soluble form, which is then processed by the baby’s liver and excreted from the body.
There are two main types of phototherapy used for newborns:
1. Conventional Phototherapy
This method involves placing the baby under a special light source, such as a fluorescent light or a halogen light. The baby is usually placed in a crib or incubator with the light positioned a short distance above their body. The baby’s eyes are often covered to protect them from the bright light, and they are typically dressed in only a diaper for maximum skin exposure.
2. Fiber-Optic Phototherapy
Fiber-optic phototherapy involves using a light-emitting pad or blanket that is placed directly on the baby’s body. This pad is designed to deliver light to the baby’s skin more directly and evenly. Fiber-optic therapy is often used for babies who need phototherapy at home or when conventional phototherapy is not available.
The duration and intensity of phototherapy vary depending on the baby’s bilirubin levels and their overall health. Babies may need to be treated for several hours or even a few days, depending on how quickly their bilirubin levels decrease.
When is Phototherapy Needed?
Phototherapy is generally used when a baby has moderate to severe jaundice or when bilirubin levels reach a point where they could cause harm. In most cases, jaundice in newborns is mild and goes away on its own without the need for treatment. However, some babies may need phototherapy if:
- Their bilirubin levels are above a certain threshold
- Jaundice develops within the first 24 hours of life
- They are premature or have other medical conditions
- The jaundice is not improving or is getting worse
- The baby shows signs of severe jaundice, such as poor feeding, lethargy, or difficulty waking up
Your healthcare provider will monitor your baby’s bilirubin levels and determine if phototherapy is necessary. In some cases, a blood test will be done to measure bilirubin levels, and based on those results, phototherapy may be recommended.
Benefits of Phototherapy for Newborns
Phototherapy is an effective and non-invasive treatment that can help reduce bilirubin levels in newborns. Some of the main benefits of phototherapy include:
Prevents serious complications: Phototherapy helps prevent the potentially dangerous consequences of high bilirubin levels, such as brain damage or hearing loss.
Safe and well-tolerated: Phototherapy is generally safe and well-tolerated by newborns. Most babies respond quickly to the treatment and begin to show improvement within 24 to 48 hours.
Non-invasive: Phototherapy does not require any surgical procedures or medications, making it a safer option for treating jaundice in newborns.
Allows for home treatment: In some cases, babies with mild jaundice can be treated with phototherapy at home using fiber-optic blankets or light pads, which can make the process more comfortable and convenient for parents.
Risks and Side Effects of Phototherapy
While phototherapy is generally considered safe, it is important to be aware of potential risks and side effects. These include:
Skin irritation: The baby’s skin may become dry or irritated due to prolonged exposure to the light. This can usually be managed with moisturizing lotions and proper care.
Dehydration: Phototherapy can sometimes lead to dehydration, as it may cause increased urination. It is important to make sure the baby is well-hydrated during treatment.
Temperature regulation: Newborns can have difficulty regulating their body temperature, and phototherapy can sometimes cause the baby to become too hot or too cold. Nurses will monitor the baby’s temperature to ensure it stays within a safe range.
Eye protection: Although the baby’s eyes are usually covered during phototherapy, there is a small risk of eye damage if the eyes are not properly shielded from the light.
In rare cases, phototherapy may cause temporary changes in the baby’s skin color, such as a tan or bronze appearance. This is usually harmless and resolves once the treatment is finished.
What to Expect During Phototherapy Treatment
If your baby needs phototherapy, the healthcare team will explain the process and what you can expect. During treatment, your baby will likely be placed under a special light or on a fiber-optic pad, depending on the type of phototherapy being used. Your baby’s eyes will be covered to protect them from the bright light, and they will be monitored closely throughout the process.
Your baby may need to stay in the hospital for a few days, depending on the severity of the jaundice. The healthcare team will monitor the baby’s bilirubin levels regularly and adjust the treatment as necessary.
Key Points to Remember:
Regular monitoring: Your baby’s bilirubin levels will be monitored regularly during phototherapy to determine the effectiveness of the treatment.
Feeding: Make sure your baby continues to feed regularly during treatment. This helps prevent dehydration and encourages the baby to pass the bilirubin through urine and stool.
Comfort and care: The healthcare team will ensure your baby is comfortable and well-cared for during treatment. You may be able to hold and cuddle your baby during breaks in treatment.
Home Phototherapy for Newborns
In some cases, if your baby has mild jaundice and is otherwise healthy, they may be treated with phototherapy at home. Home phototherapy typically involves using a fiber-optic blanket or light pad that your baby can rest on while they are at home.
Home phototherapy is convenient because it allows you to care for your baby in the comfort of your own home. However, it is still important to have your baby’s bilirubin levels monitored regularly by a healthcare provider to ensure the treatment is effective.
Conclusion
Phototherapy is a highly effective and safe treatment for newborn jaundice. By using light to break down excess bilirubin in the baby’s blood, phototherapy helps prevent serious complications such as brain damage. While phototherapy is usually safe, it is essential to monitor the baby’s response to treatment and ensure they are well-cared for throughout the process.
If your baby is diagnosed with jaundice, your healthcare provider will guide you on whether phototherapy is necessary. With early intervention and proper care, most babies recover from jaundice quickly and without any long-term effects. Phototherapy remains one of the best ways to treat newborn jaundice and ensure your baby’s health and well-being.
