| What is Croup? | Croup is a condition caused by a viral infection. The virus leads to swelling of the voice box (larynx) and windpipe (trachea). This swelling makes the airway narrower, so it is harder to breathe. |
| What are the clinical features of Croup? | 2-3/7 Coryzal symptoms Barking cough (worse at night) Harsh inspiratory stridor SOB Hoarse voice |
| What is the organism that causes Croup? | Para-influenza Virus (70%) Respiratory Syncytial virus (10%) |
| What is the pathophysiology of Acute Croup? | Viral-mediated inflammation of the mucosal surface of the larynx and large airways causing a decrease in diameter which increases airway resistance. |
| What is a Spasmodic Croup? | A recurring phenomenon associated with atopic/asthmatic history causing hyper-responsive upper airways. Managed with prophylactic inhaled corticosteroids. (Fluticasone) |
| How would you manage a moderate/severe Croup case? What if the SpO2 is <92%? What if there is a severe obstruction? | If SpO2<92%, provide oxygen via face mask or non-rebreather. A single dose of steroids (reduce inflammation): PO Dexamethasone or Inhaled Budesonide. If a severe obstruction, give Nebulised Adrenaline (local vasoconstriction in laryngeal mucosa) |
