First Aid - Croup with Stridor
First Aid - Croup with Stridor
Definition
  • Viral infection of the voicebox (larynx)
  • The croupy cough is tight, low-pitched, and barky (like a barking seal)
  • The voice or cry is hoarse (laryngitis)

Stridor: A Complication of Croup

  • Stridor is a harsh, raspy sound heard with breathing in
  • Loud or continuous stridor means severe croup
  • All stridor needs to be treated with warm mist
  • See FIRST AID for treatment recommendations

Cause

  •  Usually a parainfluenza virus

Return to School

  • Your child can return to day care or school after the fever is gone and your child feels well enough to participate in normal activities. For practical purposes, the spread of croup and colds cannot be prevented.
If not, see these topics
  •  It doesn't sound like croup, see COUGH
  • Tight purring sound when breathing out, see WHEEZING

First Aid Advice For Stridor

  • Inhale warm mist in a foggy bathroom with the hot shower running, from a wet washcloth held near the face, or from a humidifier (add warm water) for 20 minutes. (Caution: avoid very hot water or steam which could cause burns or high body temperatures)
  • If that fails, inhale cool air from breathing near an open refrigerator or taking outside for a few minutes if the weather is cold.
  • Warm mist may also be helpful for difficulty breathing or severe coughing without stridor.

HOME CARE ADVICE FOR CROUPY COUGH
  1. Reassurance:
    • Most children with croup just have a barky cough.
    • Some develop tight breathing (called stridor). 
    • Remember that coughing up mucus is very important for protecting the lungs from pneumonia.
    • We want to encourage a productive cough, not turn it off.
  2. Humidifier: If the air is dry, run a humidifier in the bedroom. (Reason: Dry air makes croup worse.)
  3. Homemade Cough Medicine:
    • From 3 months to 1 year of age, only use warm clear fluids (e.g., water or apple juice) to treat the cough. Dosage: 1-3 teaspoons (5-15 ml) four times per day when coughing. Avoid honey.
    • After age 1 year, use HONEY ½ to 1 teaspoon as needed as a homemade cough medicine.  It can thin the secretions and loosen the cough.  (If not available, can use corn syrup.)
    • After age 6, use COUGH DROPS to coat the irritated throat. (If not available, can use hard candy.)
  4. OTC Cough Medicine (DM):
    • OTC cough medicines are not recommended. (Reason: no proven benefit for children). Never use them under 4 years of age. (Reason: risk of serious side effects and not approved by FDA)
    • Honey has been shown to work better for coughs.
    • If you decide to use a cough medicine from your drugstore and your child is over age 4 years, choose one with dextromethorphan (DM). It's present in most OTC cough syrups.
    • Indication: Give for severe coughs that interfere with sleep, school or work.
    • DM Dosage: See Dosage table. Give every 6 to 8 hours for severe coughs that interfere with sleep, school or work.
  5. Coughing Spasms:  
    • Expose to warm mist (e.g., foggy bathroom).
    • Give warm fluids to drink (e.g., warm water or apple juice) if over 3 months of age.
    • Amount: If under 1 year of age, give warm fluids in a dosage of 1-3 teaspoons (5-15 ml) four times per day when coughing. If over 1 year of age, use unlimited amounts as needed.
    • Reason: both relax the airway and loosen up the phlegm
  6. Fever Medicine: For fever above 102° F (39° C), give acetaminophen (e.g., Tylenol) or ibuprofen.
  7. Observation During Sleep: Sleep in the same room with your child for a few nights. (Reason: can suddenly develop stridor at night)
  8. Avoid Tobacco Smoke: Active or passive smoking makes coughs much worse.
  9. Contagiousness: Your child can return to day care or school after the fever is gone and your child feels well enough to participate in normal activities. For practical purposes, the spread of croup and colds cannot be prevented.
  10. Expected Course: Croup usually lasts 5 to 6 days and becomes worse at night.
  11. Call Your Doctor If:
    • Stridor (harsh raspy sound) occurs
    • Croupy cough lasts over 14 days
    • Your child becomes worse

And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
