Background for Parents

As a parent, few things are as terrifying as seeing your child experience a seizure. Febrile seizures, which occur in young children and are triggered by fever, are a common cause of such incidents. While frightening, it's important to know that these seizures are usually harmless and do not indicate a serious underlying health condition. This blog post aims to provide you with a comprehensive understanding of febrile seizures, including how often they occur, their causes, what you can do if your child experiences one, and the importance of monitoring your baby’s body temperature.

By becoming informed, you can feel more confident in recognizing and responding to febrile seizures, ensuring that you’re prepared if they ever occur. Understanding the basics about these seizures, as well as when to seek medical attention, will empower you to take the necessary steps to protect your child’s health.

What Are Febrile Seizures?

Febrile seizures are convulsions brought on by a fever in infants or young children. Typically occurring between the ages of 6 months and 5 years, febrile seizures affect about 2-5% of children in this age group. The seizures are most commonly seen between 12 to 18 months of age, and while they are usually brief and not harmful, they can be alarming for parents to witness.

There are two main types of febrile seizures:

• Simple Febrile Seizures: These are the most common type, lasting less than 15 minutes and occurring only once in a 24-hour period. They usually involve the entire body.

• Complex Febrile Seizures: Less common, these last longer than 15 minutes, may occur more than once in 24 hours, and can affect only one part of the body.

It's crucial to understand that febrile seizures are linked to the rapid rise in body temperature that accompanies a fever rather than the fever itself. They are not caused by epilepsy or other neurological conditions, and most children who experience febrile seizures recover fully with no long-term effects.

Causes of Febrile Seizures

The primary cause of febrile seizures is a sudden spike in body temperature, often due to an infection. The most common infections that can lead to a fever and subsequent seizure include:

• Viral Infections: Conditions like the flu, roseola, or common colds are frequent culprits because they often cause high fevers.

• Bacterial Infections: Less common but still significant, bacterial infections such as ear infections or pneumonia can also trigger febrile seizures.

• Post-Vaccination Fevers: Although rare, some children may develop a fever after receiving vaccines, which can lead to a febrile seizure. This is more likely with vaccines that protect against diphtheria, tetanus, and pertussis (DTaP) or measles, mumps, and rubella (MMR).

Certain factors increase the risk of a child experiencing febrile seizures. These include a family history of febrile seizures, as genetic factors can make some children more susceptible. Additionally, children who have already had a febrile seizure are more likely to have another one in the future, particularly if they are under 18 months old at the time of the first seizure.

What Should Parents Do During a Febrile Seizure?

Witnessing a febrile seizure can be extremely distressing, but knowing what to do can make a significant difference in how you handle the situation. Here’s a potential guide on what to do if your child experiences a febrile seizure:

1. Stay Calm: Your immediate reaction may be fear, but it’s important to remain as calm as possible to help your child effectively.

2. Ensure the Child is Safe: Gently lay your child on a soft surface, such as a bed or the floor, away from any hard or sharp objects. If possible, turn them onto their side to prevent choking.

3. Do Not Restrain the Child: Avoid holding the child down or trying to stop the movements.

4. Avoid Putting Anything in the Child’s Mouth: Contrary to some myths, there is no need to place anything in your child’s mouth during a seizure. Doing so could cause injury.

5. Monitor the Seizure: Keep track of how long the seizure lasts. Most febrile seizures stop on their own within a few minutes.

6. After the Seizure Stops: Once the seizure is over, your child may be sleepy or confused. This is normal. Allow them to rest and recover.

7. Seek Medical Attention if Necessary: If the seizure lasts longer than 5 minutes, or if your child has difficulty breathing, is extremely drowsy, or experiences another seizure within 24 hours, seek immediate medical attention. Even if the seizure is brief, it’s advisable to consult with your pediatrician to ensure there are no underlying health issues.

Importance of Monitoring Body Temperature

Monitoring your baby’s body temperature is a key preventive measure that can help you catch a fever early and manage it before it leads to a febrile seizure. Here are some important tips for keeping a close eye on your child’s temperature:

• Use a Reliable Thermometer: Digital thermometers are generally the most accurate. For infants under 3 months, a rectal thermometer is recommended for the most precise readings. For older infants and young children, ear or forehead thermometers can be convenient and effective.

• Check Temperature Regularly: During an illness, especially if your child seems warmer than usual or is acting unusually fussy, check their temperature every few hours, including during the night.

• Manage Fevers Early: If your child’s temperature starts to rise, you can manage it with proper hydration, dressing them in light clothing, and using fever-reducing medications like acetaminophen or ibuprofen, as advised by your pediatrician. Always follow the recommended dosage instructions and consult your doctor before giving medication to very young children.

• Proactive Monitoring: Especially during a viral illness, proactive monitoring can help you identify a fever before it spikes too high. This is particularly important for children who have had febrile seizures in the past.

By being vigilant about your child’s temperature, you can take steps to prevent a fever from reaching the point where a febrile seizure might occur.

Prevention and When to Seek Medical Advice

While febrile seizures cannot always be prevented, there are steps you can take to reduce the likelihood of them occurring:

• Manage Fevers: As previously discussed, managing fevers as soon as they are detected is crucial. Use appropriate fever-reducing strategies and ensure your child is comfortable and hydrated.

• Keep Vaccinations Up to Date: Ensure your child is up-to-date with vaccinations, as some infections that cause high fevers can be prevented with immunizations.

• Know When to Seek Help: If your child has a febrile seizure that lasts longer than 5 minutes, or if they have multiple seizures in a 24-hour period, seek medical attention immediately. Also, if your child has a seizure before they reach 6 months of age or after 5 years, it’s important to consult a doctor, as these seizures may have different underlying causes.

Recognizing the signs that warrant further medical evaluation is key to ensuring your child’s well-being. For instance, if your child’s febrile seizure is complex—lasting longer than 15 minutes, affecting only one part of the body, or occurring multiple times during the same illness—it’s advisable to follow up with a pediatric neurologist for further assessment.

Summary

Febrile seizures, while alarming, are a relatively common occurrence in young children and are usually not a sign of a serious health problem. By understanding what febrile seizures are, what causes them, and how to respond if your child experiences one, you can be better prepared to handle the situation calmly and effectively.

Monitoring your baby’s body temperature, especially during illnesses, is a crucial step in preventing febrile seizures. With proactive management and an informed approach, you can minimize the risk and ensure your child’s health and safety. Remember, if you ever have concerns about your child’s health or experience with febrile seizures, don’t hesitate to consult with your pediatrician for guidance and reassurance.
