Laryngitis in children

Laryngitis is an inflammation of the larynx, the part of the airway where the vocal cords are located. In children, due to the anatomically narrow larynx, inflammation can quickly lead to difficulty breathing and a "barking" cough.

Laryngitis most often develops due to a viral infection (acute respiratory viral infection, influenza, parainfluenza), but can also be associated with allergies, vocal strain, or exposure to irritants (smoke, dry air).

Causes and risk factors

Most common causes:

  • Viral respiratory infections (parainfluenza, influenza, RSV, adenoviruses)
  • Bacterial infections (less common, usually a complication of a viral infection)
  • Allergic reactions and swelling of the laryngeal mucosa
  • Mucosal irritation due to cigarette smoke, dry or cold air

Risk factors:

  • Age 6 months – 5 years (narrowest larynx, high risk of croup)
  • Frequent acute respiratory viral infections, attending daycare
  • Allergic diseases
  • Congenital respiratory tract abnormalities
Causes and risk factors

Main symptoms

Classic manifestations of laryngitis in children:

  • Hoarseness or loss of voice
  • Dry, "barking" cough, especially at night
  • Sore or scratchy throat
  • Runny nose, fever, signs of acute respiratory viral infection
  • Sometimes difficulty breathing (stridor)

Table of symptoms

Symptom Description When to be concerned
Hoarseness Child wheezes, speaks quietly Lasts more than 2 weeks
"Barking" cough Harsh, sharp, irritating Increasing, interferes with breathing
Fever More common 37–38.5°C Above 39°C, difficult to control
Difficulty breathing Noisy inhalation, retractions Any progressive worsening

Warning signs (when to see a doctor immediately)

Call an ambulance immediately or go to the emergency room if:

  • The child is having difficulty breathing, with a whistling or "wheezing" sound (inspiratory stridor) when inhaling.
  • Skin retractions are visible above the jugular notch, between the ribs, or at the bottom of the neck when breathing.
  • The child is restless, unable to articulate words, cries silently, or, conversely, becomes lethargic.
  • Bluish discoloration of the lips or nasolabial triangle appears.
  • Temperature above 39–39.5°C and poorly responds to antipyretics.
  • The child refuses to drink or swallow, and drools.

Diagnostics

In most cases, the diagnosis of laryngitis is made clinically, based on complaints and an examination.

The doctor may:

  • Examine the throat, nose, and ears, and listen to the lungs.
  • Assess the respiratory rate and blood oxygen saturation (pulse oximetry).
  • If necessary, order a complete blood count, swabs, and viral tests.
  • In severe cases, consult an ENT specialist, possibly perform a laryngeal endoscopy in a hospital.

Treatment of laryngitis in children

Treatment tactics depend on the severity of the condition. For mild laryngitis, treatment is usually carried out at home.

Key areas:

  • Drink plenty of warm fluids (water, compotes, warm tea – age-appropriate)
  • Humidify the air (40–60%), ventilate the room
  • Antipyretics for temperatures above 38–38.5°C (paracetamol, ibuprofen, depending on age)
  • For severe edema or croup – inhaled or systemic glucocorticosteroids, inhalations with adrenaline, oxygen, which can only be determined by a doctor in the hospital.

Antibiotics are prescribed only if there are signs of a bacterial infection – their necessity is assessed by a doctor.

General information

Home care and what not to do

Care Recommendations:

  • Keep the child in an upright or semi-sitting position; do not force them to lie horizontally if breathing is difficult.
  • Speak calmly, distract them, and do not provoke crying (crying increases shortness of breath).
  • Ensure adequate fluid intake in small amounts.

What NOT to do:

  • Do not expose the child to hot steam, as this can cause burns and increased swelling.
  • Do not rub the chest and neck with harsh warming agents.
  • Do not use essential oils or harsh inhalations without a doctor's recommendation.
  • Do not give Unprescribed cough suppressants and "strong" throat sprays (may trigger spasms)

Laryngitis in children under 3 (False croup)

In children under 3–4 years of age, inflammation of the larynx can lead to the development of false croup—acute stenosing laryngotracheitis.

It is characterized by:

  • Sudden attack of a "barking" cough at night
  • Noisy inhalation, wheezing
  • Hoarseness
  • Varying degrees of breathing difficulty

If croup is suspected, the child should be examined by a doctor. If breathing is compromised, emergency care and sometimes hospitalization are needed.

Prevention

Preventive measures include:

  • Treatment and prevention of acute respiratory viral infections, hand hygiene
  • Humidification and regular ventilation of the room
  • Quitting smoking in the home and around the child
  • Hardening and sufficient physical activity appropriate to age
  • Vaccination according to the national calendar (it reduces the risk of severe respiratory infections that can lead to laryngitis)

FAQ

How long does laryngitis typically last in a child?

Acute laryngitis typically lasts 5-7 days, with cough and hoarseness sometimes persisting a little longer. If the condition persists (>2 weeks), a follow-up consultation with a doctor is necessary.

Is it okay to go for a walk with laryngitis?

If your child's temperature is normal and you're feeling well, short, leisurely walks are fine, without risking hypothermia. It's best to consult your pediatrician before making this decision.

Are inhalations with a nebulizer necessary?

Inhalations can be used as directed by a doctor (saline solution, sometimes medications). You should not try any "medicinal" inhalations on your own.

Is laryngitis life-threatening for a child?

Most cases of mild laryngitis are harmless and respond well to treatment. Danger arises when severe laryngeal stenosis (false croup) develops, so it's important to recognize warning signs and seek help promptly.

Can laryngitis be treated solely with folk remedies?

Folk remedies (warm drinks, humidifying the air) can be helpful as a supplement, but they do not replace medical attention, especially if symptoms are severe.
