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]
Laryngeal edema is a common cause of stridor post extubation (occurring from pressure of the endotracheal tube on the mucosa as a result of endotracheal tube that is too large (e.g. pediatrics), cuff over inflation, and prolonged intubation times.); [2] tumor (e.g., laryngeal papillomatosis, squamous cell carcinoma of larynx, trachea or esophagus);
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."
Symptoms include a chest cold with fever, cough, and sore throat. Most children get better without medicine, but doctors say, you should seek medical advice if your child: Is lethargic or not ...
A bacterium called Mycoplasma pneumoniae causes two types of respiratory tract infections: the more common chest cold, tracheobronchitis, and the less common lung infection, walking pneumonia.
The causes of upper airway obstructions can be acute or chronic. More acute causes of upper airway obstruction include foreign body aspiration, blunt trauma to the neck, infections, and swelling due to allergies or other inflammatory conditions. [3] In children, viral infections such as croup or epiglottitis are frequent causes. [4]
A wheeze is a clinical symptom of a continuous, coarse, whistling sound produced in the respiratory airways during breathing. [1] For wheezes to occur, part of the respiratory tree must be narrowed or obstructed (for example narrowing of the lower respiratory tract in an asthmatic attack), or airflow velocity within the respiratory tree must be heightened.
[1] [3] [5] In the pediatric setting, the reported most common causes of NPPE are both infectious in nature: croup and epiglottitis. [1] Other reported causes include endotracheal tube obstruction (e.g., from patient biting down on tube), tumors/masses compressing the upper airway, choking on foreign objects, strangulation.
