Delayed Cord Clamping And Jaundice – What You Need To Know

Delayed Cord Clamping And Jaundice – What You Need To Know

We now know that delayed cord clamping has a whole host of benefits – both immediate and long-term.

When we make birth decisions, we want to be sure we’re making the best choices. Often that means weighing up the benefits and risks of each option.

In recent decades, immediate umbilical cord clamping was the norm. Recently there’s been a shift towards routinely delaying cord clamping.

As a newer practice becomes more common, people start to look for connections with possible benefits or risks.

Some medical professionals had voiced their concern about an increased risk of neonatal jaundice (hyperbilirubinemia) among babies who had delayed cord clamping. In fact, this concern was sometimes used as a reason to deter patients from choosing delayed cord clamping, despite the many proven benefits.

Does Delayed Cord Clamping Increase The Risk Of Jaundice?

The World Health Organization (WHO) recommends routine delayed cord clamping for all babies, unless they need immediate medical attention that can’t be accessed on or near their mother.

The WHO makes its recommendations after extensive research and data review. Before making this recommendation, it reviewed data that revealed several significant benefits. One benefit was that infants who had delayed cord clamping had much better iron stores. This significantly lowered their risk of iron deficient anaemia in the first six months.

Cord blood contains around one third of a baby’s volume of blood. So the baby stands to lose a significant amount of iron (and blood in general) if the cord is clamped immediately.

The WHO also found the rate of jaundice was not higher among newborns who had delayed cord clamping. However, they found an increased need for phototherapy to treat jaundice among newborns who had delayed cord clamping.

Even with the increased risk of the need for phototherapy, there’s little to no evidence to suggest that the risk outweighs the many known benefits of delayed cord clamping.

What Is Jaundice?

The body produces a substance called bilirubin, which breaks down old red blood cells. While baby is in utero, the placenta is responsible for removing bilirubin. After birth, baby’s liver takes over the task of eliminating bilirubin from the blood.

In 60% of newborns, hyperbilirubinemia (elevated levels of bilirubin in the blood), or jaundice, occurs.

When baby has yellowing of the skin and whites of the eyes, or lethargy, then normal newborn jaundice is typically the culprit.

Is Jaundice Dangerous?

In short, jaundice is a descriptive symptom and not a disease.

When we first started testing babies for jaundice, we assumed that elevated bilirubin was automatically a health risk. We now know that bilirubin is a powerful antioxidant. It probably has an important role in the transition from womb to world.

If we take a moment to look at biological norms, it wouldn’t make sense for 60% of healthy babies to have jaundice if it were a serious and abnormal complication. For healthy, full-term infants born after 37.5 weeks gestation, jaundice is rarely serious, and rarely requires treatment. Usually, it just needs to be monitored.

Preterm babies, those with low birthweight for gestational age, and infants not properly transferring milk (i.e. dehydrated) are at risk of jaundice with potential complications. Blood group incompatibility, certain diseases and infections can also be associated with jaundice. However, there is treatment available to prevent or lower the risk of complications.

How Is Jaundice Treated?

It’s important to remember that jaundice is simply a descriptive symptom, much like coughing. Like a cough, jaundice has different causes. The reason for the jaundice determines how it’s treated.

There are three types of jaundice:

Physiological Jaundice is often called normal newborn jaundice. It occurs from around day 2-4 of life and is resolved by 1-2 weeks (or 3 weeks in premature babies). It is simply due to the transition that takes place after birth, when the immature liver must start to process the bilirubin that had been processed by the placenta before birth. There’s no underlying disease or illness associated with this type of jaundice.

Babies with physiological jaundice are monitored, and might not require any treatment. If baby is lethargic, too sleepy to eat, or bilirubin levels are very elevated, phototherapy might be recommended. Additional IV fluids might be given to help the body flush bilirubin, if levels get too high.

Pathological Jaundice is jaundice caused by an underlying medical condition or concern. This possibility is always considered when baby shows signs of illness, or if jaundice levels are very high within 24 hours to 10 days of life.

Pathological jaundice might also be treated with phototherapy to help lower bilirubin levels. The underlying cause for the jaundice (infection, disease, etc) is treated at the same time.

Breast Milk Jaundice is a bit of a silly term, considering breast milk is our biological norm. Nonetheless, this term is used when an exclusively breastfed baby has jaundice that appears around 5-7 days of life, and persists for a few weeks, even a few months. This is physiologically normal, and nothing to be concerned about. Even so, the baby will probably be monitored, to make sure the higher bilirubin levels are not caused by low milk intake, or by pathological conditions.

Breast milk jaundice rarely requires treatment. It’s important parents wake any sleepy babies to be sure they’re transferring plenty of milk via frequent feeds. It’s a good idea to work with an IBCLC lactation consultant if there are concerns about milk transfer.

If baby is overly lethargic, or less than 37.5 weeks gestation, phototherapy might be beneficial.

We used to treat breast milk jaundice with formula. Now, unless a baby is genuinely unable to get enough breast milk, we know there’s no benefit in routinely supplementing jaundiced babies with formula.

Does Phototherapy Have Risks?

Phototherapy is a noninvasive treatment. It can be done via admission to hospital, where baby will be placed under a bilirubin light. It can also be done via home care (in some areas) with a portable bili blanket. This method is used for cases of borderline hyperbilirubinemia (levels less than 19).

The treatment and monitoring of jaundice often requires a heel prick for blood testing. It can be unpleasant, but it carries little risk.

Does The Benefit Of Delayed Cord Clamping Outweigh The Risk Of Jaundice And Phototherapy?

In short, in healthy full-term infants, delayed cord clamping has many known benefits. The benefits are very likely to outweigh the risk of jaundice, even when phototherapy is required.

This is often true for preterm and unwell infants, too. If you’re at risk for a preterm birth, discuss delayed cord clamping with a neonatologist, so that you have a plan that everyone is confident about.

Delayed cord clamping decreases the risk of iron deficient anaemia for baby’s first six months of life. It also has many other short and long term benefits.
