Croup (/ k r uː p / KROOP), also known as croupy cough, is a type of respiratory infection that is usually caused by a virus. [2] The infection leads to swelling inside the trachea, which interferes with normal breathing and produces the classic symptoms of "barking/brassy" cough, inspiratory stridor and a hoarse voice. [2]
Stridor (from Latin 'creaking/grating noise') is an extra-thoracic high-pitched breath sound resulting from turbulent air flow in the larynx or lower in the bronchial tree.It is different from a stertor, which is a noise originating in the pharynx.
The swollen throat is often accompanied by a serious respiratory condition, characterized by a brassy or "barking" cough, stridor, hoarseness, and difficulty breathing; and historically referred to variously as "diphtheritic croup," [13] "true croup," [14] [15] or sometimes simply as "croup."
Corticosteroids, although useful in other respiratory disease such as asthma and croup, have no proven benefit in bronchiolitis treatment and are not advised. [ 9 ] [ 8 ] [ 12 ] [ 57 ] [ 58 ] Additionally, corticosteroid therapy in children with bronchiolitis may prolong viral shedding and transmissibility. [ 9 ]
X-ray findings may include subglottic narrowing. The priority is to secure the patient's airway, and to rule out croup and epiglottitis which may be fatal. Suspicion for tracheitis should be high in cases of onset of airway obstruction that do not respond to racemic epinephrine. [citation needed]
This form of treatment is often prescribed in conditions where people have difficulty in breathing. An oxygen tent can be used in either a hospital setting or outside a health-care facility, and can be recommended for short- or long-term therapy.
Treatment depends on how severe the patient's condition is and the cause of the obstruction. If the patient is choking on a foreign body, the Heimlich maneuver can be used. More invasive methods, such as intubation, may be necessary to secure the airway. In severe cases, intubation may be difficult and a cricothyrotomy or tracheostomy may be ...
