Also known as Acute Laryngotracheobronchitis
Croup (or laryngotracheobronchitis) is a respiratory condition that is usually triggered by an acute viral infection of the upper airway. The infection leads to swelling inside the throat, which interferes with normal breathing and produces the classical symptoms of a "barking" cough, stridor, and hoarseness. It may produce mild, moderate, or severe symptoms, which often worsen at night. It is often treated with a single dose of oral steroids; occasionally epinephrine is used in more severe cases. Hospitalization is rarely required.Source: Wikipedia
Within all the people who go to their doctor with croup, 94% report having cough, 77% report having fever, and 66% report having difficulty breathing. The symptoms that are highly suggestive of croup are difficulty breathing and wheezing, although you may still have croup without those symptoms.
Patients with croup often receive nebulizer therapy, influenzavirus antibody assay, other respiratory therapy, diagnostic bronchoscopy and biopsy of bronchus, tracheoscopy and laryngoscopy with biopsy and nonoperative urinary system measurements .
The most commonly prescribed drugs for patients with croup include dexamethasone topical product, prednisolone, dexamethasone, epinephrine, pheniramine / phenylpropanolamine / pyrilamine, carbinoxamine / pseudoephedrine, chlorpheniramine / hydrocodone / phenylephrine, chlorpheniramine / dextromethorphan / pseudoephedrine, methylprednisolone topical, helium / oxygen, triprolidine (actifed), dextromethorphan / guaifenesin / phenylpropanolamine and alteplase .
