What Is SIDS?

Sudden infant death syndrome, otherwise called SIDS, is the sudden and unexplained death of an otherwise healthy infant, generally during sleep. As most infants die in the crib during their sleep, it is also called crib death or cot death. It can be difficult to find the cause of SIDS. It is thought to be due to defects in the part of the infant’s brain that controls breathing and wakes up the body from sleep.

Doctors and researchers have identified some factors that might be increasing the risk of SIDS, and there are various measures that parents can take to protect their children from SIDS. The most important advice from doctors is to put the baby to sleep on his or her back.

SIDS is rare, but it is still the most common cause of death for infants under a year old in the U.S. Babies between the ages of two and four months are most commonly affected.

Does SIDS Result in Any Symptoms?

SIDS does not result in any symptoms. In addition, there are no warning signs to prevent infants from developing SIDS. Babies who are sleeping suddenly die.

What Causes SIDS?

Researchers are yet to conclude the exact cause of SIDS. They believe a combination of the following factors might be responsible:

1) Physical Factors:

Brain Development - Most of these babies are born with some defects in the brain, which makes them more prone to die suddenly. The part of the brain that is responsible for breathing and sleep arousal does not mature enough.

Premature Birth - In babies born prematurely, the chances of the brain not fully developing increase. Such babies do not have proper control over breathing and heart rate.

Respiratory Infection - Breathing problems due to a cold or any other respiratory infection can lead to SIDS.

2) Environmental Factors:

Sleeping Position - Babies that are put to sleep on their stomach or side might find it more difficult to breathe.

Bed Sharing - Babies sleeping with their parents in their bed or on any other mattress that is not specially made for them increases the chances of injury, asphyxia, and strangulation.

Being Too Warm - The risk increases if the baby is too warm while sleeping.

Blocked Airway - If a baby rolls over while sleeping on a soft surface like a comforter or soft mattress, it can block his or her airway.

3) Other Causes - Using an unsafe or old crib, using a very soft mattress, filling the crib with soft toys while the baby is sleeping, not using a pacifier, and not breastfeeding.

What Are the Risk Factors for SIDS?

Apart from the physical and environmental factors, the following factors also increase the risk of SIDS:

  1. Boy babies.

  2. Infants between two to four months of life. More than 80 percent of babies who die of SIDS are under six months of age.

  3. Having siblings or cousins who died due to SIDS.

  4. Babies exposed to secondhand smoke.

  5. Babies with low birth weight.

  6. Sleep apnea (breathing stops in periods while sleeping).

Mothers can also increase the risk of their baby dying of SIDS. Mothers who:

  • Are younger than 20 years.

  • Smoke cigarettes.

  • Use drugs.

  • Drink alcohol.

  • Do not have proper prenatal care.

In order to prevent SIDS, try to avoid as many of these risks as possible.

How Does a Doctor Diagnose SIDS?

There is no specific test to determine that the infant died due to SIDS. The doctor rules out all possible causes of death before declaring the cause to be SIDS. The tests and investigations done by the doctor include the following:

  • Examining the infant’s body after death.

  • Examining the place where the death occurred.

  • Evaluating the symptoms that the baby had before death.

Is There Any Treatment for SIDS?

Sadly, there is no treatment for SIDS. As there are no symptoms or signs that can alert the parents before the sudden death, nothing can be done. But there are various ways to reduce the risk.

What Can Be Done to Reduce the Risk of SIDS?

The following tips can possibly help reduce the risk of SIDS:

Put Babies to Sleep on Their Back - Until they are one year old, babies should be put on their backs for sleep. While they are awake, parents can put them on their side or tummy, as it will make the baby grow stronger. But always keep a close eye on them.

Prenatal Care - Get early and regular prenatal care. Pregnant women should follow a healthy diet and avoid drinking alcohol and smoking. This can help reduce the chances of premature birth and, in turn, reduce SIDS.

Use a Firm Mattress - Always make the baby sleep on a firm bed with a tightly fitted sheet. Avoid using fluffy comforters. Never put soft toys or pillows in the crib.

Breastfeeding - Breastfeed the baby at least for the first six months. Until suggested by the doctor, do not give the baby water, sugar, or formula milk.

Pacifier - Give the baby a pacifier while sleeping.

Avoid Overheating - The room temperature should not be too warm, and parents should avoid overcovering or overdressing their baby.

Do Not Share a Bed - Infants should sleep in a separate crib that is placed close to the parent’s bed. Never share a bed, especially if parents take medicine or alcohol.

Do Not Smoke Around the Baby - Do not smoke during pregnancy or let anyone smoke near the baby. Secondhand smoke can be bad for the baby.

Vaccination - Regular checkups and vaccinations to prevent infections can reduce the risk of SIDS.

Avoid using baby monitors and other devices that claim to reduce the risk of SIDS.

Quick Facts:

  • The sudden and unexpected death of a child younger than a year is called sudden infant death syndrome.

  • Such infants usually die in their sleep.

  • Infants between two to four months are more prone to SIDS.

  • The doctor will declare the death of the infant as SIDS if no other cause is identified.

  • The risk of SIDS can be reduced by placing an infant to sleep on his or her back.

How to Cope With the Loss of the Baby?

It is essential to get emotional support after losing a baby to SIDS. Most mothers feel guilt and grief. Talking to other parents who have lost their children to SIDS also helps. Communicate with friends, family, or a counselor. Losing a child strains a relationship, so try to be open with the partner. Giving oneself time to grieve may help.

Conclusion:

Overall, SIDS is an extremely rare syndrome, but it affects the parents in every aspect, including their emotional, mental, and physical well-being. It is therefore crucial to spread awareness about this syndrome so that parents can protect their babies from the risk factors that can cause SIDS.

Frequently Asked Questions

1.

What Is SIDS?

SIDS, also called sudden infant death syndrome, is the sudden unexplained death of a seemingly healthy baby less than the one-year-old, usually during sleep. It does not have a known cause even after a thorough investigation.

2.

What Is the Cause of Sudden Infant Death Syndrome?

SIDS is also known to be crib death because babies often die in their cribs. Although the cause is not known, it appears that SIDS might be associated with some defects in the part of a baby's brain that controls breathing and waking up from sleep.

3.

Are There Any Warning Signs for SIDS?

There are no warning signs for SIDS because it is very difficult to comprehend. In addition, it is unexpected, and parents cannot prepare for them ahead of time. However, the signs or symptoms included are the infants being drowsy when awake, wheezing, and infants consuming less than half the normal amount of fluids in the last 24 hours before their deaths.

4.

Why Is SIDS Considered To Be Dangerous?

Sudden infant death syndrome, also known as cot death, is considered to be dangerous because it is the sudden unexplained death of an infant below one year. Diagnosis will remain unexplained even after a thorough autopsy and detailed death scene investigation. SIDS usually occurs during sleep. Typically death occurs between the hours of 00:00 and 09:00. There is usually no noise or any evidence of a struggle. SIDS remains the leading cause of baby mortality.

5.

How Prevalent Is SIDS?

It is more prevalent in babies between 1 and 4 months, and it can happen at any time during the first year of life. It is most commonly seen in male babies than female babies and more likely seen in babies with family history.

6.

When Can You Stop Worrying About SIDS?

Babies at risk of SIDS are up to the age of four months, and most SIDS deaths happen within the first six months. Therefore you can stop worrying about it after 12 months.

7.

When Does a Baby Have the Highest Risk for SIDS?

The baby is at the highest risk for SIDS during the following situations:
- Sleeping on the stomach.
- Premature birth.
