Common respiratory disorders in children Flashcards
Laryngomalacia
- Most common
- The laryngeal structure is malformed and floppy causing the tissue to fall over the airway and partially block it
The symptoms of laryngomalacia
Stridor, difficulty breathing
Usually resolve by 2 years
Tracheo oesophageal fistula
- It is an abnormal connection between these two tubes
- So swallowed liquid or food can be aspirated into the child’s lungs
- Feeding into the stomach directly can also lead to reflux and aspiration of stomach acid and food
- Observe child’s respiratory effort and chest movement
What are the common respiratory infections?
- Upper Respiratory Tract Infections
2. Lower Respiratory Tract Infections
Upper Respiratory Tract infections
- Child < 5 years will experience about 3-8 episode/ year and over 90% are cause by a virus which antibiotic is no necessary
- Common cold ( acute infective rhinitis )
- Pharyngitis / Tonsilitis
- Sinusitis
Lower respiratory tract infections
- Acute Laryngotracheobronchitis ( Coup )
- Bronchiolitis . Bronchitis
- Pneumonia
What is the difference between upper respiratory tract infections and lower respiratory infections?
While lower respiratory tract infections involve the airways below the larynx, upper respiratory tract infections occur in the structures in the larynx or above. People who have lower respiratory tract infections will experience coughing as the primary symptom.
Acute Laryngotracheobronchitis ( Coup ) Lower Respiratory Tract infection
- It is caused by parainfluenza viruses or other causative agents : Respiratory Syncytial Virus ( RSV ) , Adenovirus
- Susceptible to 6 months - 5 years and peaks between 6 months to 2 years
- Westley Croup Score is used to determine severity
What are the symptoms of Acute Laryngotracheobronchitis ( Coup )
Fever, breathing problem at night, a few days of UTRI followed by stridor and a harsh barking cough
What is the treatment of Acute Laryngotracheobronchitis ( Coup )?
- Humidified oxygen ; Inhaled epinephrine
- Corticosteroids ; PO/IV Dexamethasone
What is the complication of Acute Laryngotracheobronchitis ( Coup )?
- Airway obstruction , respiratory failure, dehydration
- Pneumonia, hypoxia, hypercapnia
The prevention of Acute Laryngotracheobronchitis ( Coup )
Vaccination
What is bronchiolitis ?
Bronchiolitis is a viral infection that causes the airways (bronchioles) in the lungs to become narrow,
What is Croup, or acute laryngotracheobronchitis?
Croup, or acute laryngotracheobronchitis, is an acute infectious respiratory disease of infants and children caused by infection of the larynx or the trachea - alone or together. It can cause partial or severe obstruction of the airway, which results in breathing difficulties and coughing
Bronchiolitis
It can occur in any child < 2 years old
Causative agent : Respiratory Syncytial Virus ( RSV ), Rhinovirus and Influenza virus
What are the symptoms of bronchiolitis?
- It starts with UTRI, symptoms worsen 3-5 days
- Peak 5-7 days, resolve by 2-3 weeks
What are the risk factors of bronchiolitis?
- Prematurity
- Congenital diseases
What is the treatment of bronchiolitis?
- Oxygenation aim SaO2 > 95%
- Hydration & nutrition
- relieve nasal congestion
- bronchodilator
