Managing croup

Fact Checked

Croup is an infection that affects the respiratory system specifically the larynx, trachea and the bronchial tubes in the lung. It is usually due to virus and bacterial infection. It is characterized by obstruction of breathing and a barking cough. There is swelling around the vocal cords, windpipe or trachea and bronchial tubes.

Coughing forces air through this narrow passage and produce a noise like a barking seal and taking a breath results to a high-pitched whistling sound or stridor. Infants and children are susceptible to croup.

  • Bring the affected child to a steamy room. Close doors and windows of the bathroom. Run the shower in hot setting. Let the child sit inside the bathroom and instruct him/her inhale the hot steam coming from the shower for relief from the congestion. Another alternative is exposing the child to the cool air at night and using a cool air vaporizer near the bed of for relief from the symptoms.
  • Take the prescribed medications to lessen the swelling in the upper airways such as corticosteroids that are taken orally or by injection. If croup is caused by bacteria, use the prescribed antibiotic.
  • If there is a foreign object responsible for the obstruction of the airways, there is a need to place a tube into the larynx via the mouth or nose.
  • Drink plenty of fluids to prevent dehydration.
  • Place a damp and cold cloth around the throat to lessen the swelling and pain.
