Managing Nasal Congestion and Post-Nasal Drip in Infants

Nasal congestion and post-nasal drip?

Hello Dr.
Tsai: My baby girl is currently six months old, measuring about 70 cm in height and weighing 7.5 kg.
She consumes 150 cc every four hours and has sweet potato puree or porridge 1 to 2 times a day.
For the past month, she has been experiencing nasal congestion, post-nasal drip, and excessive crying.
My sister's post-nasal drip is quite severe; sometimes she has nasal congestion but never has a runny nose.
Whenever the post-nasal drip accumulates to a certain amount, she starts coughing until she expels a significant amount of phlegm, after which the coughing stops, and she doesn’t cough again until the post-nasal drip builds up again to a certain level, leading to another episode of coughing and vomiting.
She has been on medication for a long time without improvement, and this cycle keeps repeating.
What should I do?

Dr. Cai Zhengxian reply Pediatrics

Dear Mom,
I apologize for the delay in responding due to my job transfer.
May I ask if you or your husband have any allergic tendencies? When an infant under one year old presents with symptoms such as coughing and runny nose, the first consideration should be upper respiratory infection or bronchiolitis.
However, if the symptoms persist for more than two weeks without fever, please be cautious as it may indicate an allergic reaction.
Typically, we doctors will also check if the child has any rashes on their skin, whether introducing solid foods exacerbates the symptoms, or if there are signs of cow's milk protein allergy.
If you answer "yes" to any of these questions, please take your child to a pediatric allergist for evaluation and follow-up.
As for a simple method to relieve nasal congestion in children, you can dampen a towel with warm water and place it over the nose; after five minutes, the child's nasal congestion should improve.
Whether or not to use a pediatric nasal aspirator is a matter of personal preference.
The Tainan City Hospital cares about you and your baby's health!

More Info

Managing nasal congestion and post-nasal drip in infants can be quite challenging, especially when the symptoms persist despite medication. In your case, your six-month-old daughter is experiencing significant nasal congestion and post-nasal drip, which leads to coughing and vomiting when the mucus accumulates. This situation can be distressing for both the child and the parents, and it’s essential to approach it with a comprehensive understanding of potential causes and management strategies.

Understanding the Symptoms
Nasal congestion in infants can arise from various causes, including viral infections (like the common cold), allergies, or even anatomical issues such as nasal polyps or adenoid hypertrophy. Post-nasal drip occurs when excess mucus accumulates in the back of the throat, leading to coughing as the body attempts to clear the mucus. In infants, this can be particularly problematic because they may not be able to effectively clear their airways.

Management Strategies
1. Humidification: Keeping the air in your home humid can help alleviate nasal congestion. A cool-mist humidifier in your child's room can add moisture to the air, which may help thin the mucus and make it easier for your baby to breathe.

2. Saline Nasal Drops: Using saline nasal drops can help moisten the nasal passages and loosen mucus. You can apply a few drops in each nostril, followed by gentle suction with a bulb syringe to clear out the loosened mucus. This can be particularly helpful before feeding or sleeping.

3. Positioning: Elevating your baby's head slightly while sleeping can help reduce post-nasal drip. However, ensure that the baby is always placed on their back to sleep, as this is the safest position to reduce the risk of Sudden Infant Death Syndrome (SIDS).

4. Hydration: Ensure your baby is well-hydrated. Adequate fluid intake can help thin mucus secretions. Since your baby is six months old, you can introduce small amounts of water in addition to breast milk or formula.

5. Avoid Irritants: Keep your baby away from smoke, strong odors, and other environmental irritants that can exacerbate nasal congestion. This includes avoiding exposure to secondhand smoke and strong perfumes.

6. Medication Review: If your baby has been on medication for an extended period without improvement, it may be time to consult your pediatrician for a review. They may consider adjusting the medication or exploring other treatment options, such as allergy testing if allergies are suspected.

7. Consult a Specialist: If the symptoms persist despite these measures, it may be beneficial to consult an ear, nose, and throat (ENT) specialist. They can evaluate for any anatomical issues or other underlying conditions that may be contributing to your baby's symptoms.

When to Seek Immediate Medical Attention
If your baby experiences difficulty breathing, persistent high fever, or if the coughing leads to choking or severe distress, seek immediate medical attention. These could be signs of a more serious condition that requires prompt evaluation and treatment.

Conclusion
Managing nasal congestion and post-nasal drip in infants requires a multifaceted approach that includes environmental modifications, gentle nasal care, and possibly medical intervention. Since your baby has been experiencing these symptoms for a while, it’s crucial to work closely with your pediatrician to ensure that you are addressing the underlying causes effectively. With the right strategies and support, you can help alleviate your baby's discomfort and improve her overall well-being.
