He may refuse to speak or speaks in a very soft voice and may drool. He usually seems frightened and refuses to lie supine, preferring to sit up with the neck extended. A lateral neck radiograph shows an abnormally thickened epiglottis.
Acute epiglottitis is an airway emergency. The child must never be left unattended or transported out of an area without equipment and personnel for emergency airway management. The epiglottis must be visualized under controlled conditions by a staff member skilled in airway management, and intubation is almost always required to secure the airway. Retropharyngeal abscess is another cause of upper airway obstruction in young children.
It results from bacterial infection of the lymph nodes that drain the head and neck to the retropharyngeal region. The infection results in expansion of what is normally a potential space, which then encroaches on the airway lumen.
The diagnosis is confirmed by a lateral neck radiograph with the child positioned with the neck moderately extended. The film reveals widening of the prevertebral space. Treatment includes careful attention to the airway, IV antibiotics, and, in some cases, surgical drainage of the abscess.
Asthma, a common chronic disease in children, is characterized by coughing, wheezing, and shortness of breath. Because cough is a principal symptom of asthma, it is possible to mistake the cough of asthma for croup. Foreign body aspiration rarely presents with stridor, although it may be the presenting complaint with a high tracheal or esophageal foreign body. It is easy to miss the diagnosis initially because the child may not have the typical history of choking on an object.
Radiographs may be helpful if the foreign body is radio-opaque, but films may also be completely normal. When a foreign body is suspected, therefore, rigid bronchoscopy is appropriate to identify and remove the foreign body. Airway compression intraluminal or extraluminal has a variety of causes, including airway hemangioma, hematoma caused by trauma, cyst, tumor, lymphadenopathy, and a foreign body in the esophagus. Although it is wise to include airway compression in the differential diagnosis of croup, the presentation is usually far more insidious, with symptoms that have gradually become evident or worse.
Allergic reaction and angioneurotic edema can present as acute airway obstruction. Anaphylaxis is a severe, systemic manifestation of type I hypersensitivity and usually occurs shortly after exposure to the offending antigen. The child often exhibits a combination of symptoms, including urticarial rash, respiratory distress caused by bronchospasm and airway edema, and cardiovascular collapse. Stridor may be a rare presenting symptom of anaphylaxis and should therefore be included in the differential diagnosis.

CME: That characteristic cough: When to treat croup and what to use. Oxygen delivery at less than 8 litres per minute will not drive the nebuliser adequately Admission criteria As a 'rule of thumb' children without stridor do not need to be admitted This decision would be influenced by the distance parents live from the hospital, the reported severity of symptoms at home and past history of severe croup.
Infection control Children presenting to hospital with croup should be managed with droplet precautions. Discharge criteria The child must meet all of the following criteria: Clinically improved Steroids received No stridor at rest No other clinical or social concerns.
Nursing Minimal nursing intervention is encouraged to avoid distressing the child and increasing respiratory distress. Patients should remain in a position of comfort.
Children with croup require close observation. Record baseline observations: heart rate, respiratory rate, oxygen saturations and temperature on the Observation and Response Tool and document additional observations on the Clinical Comments chart.
The presence or absence of the following clinical features should be assessed and documented: stridor barking cough degree and type of recession i. Observations should be recorded at least hourly whilst in the emergency department. Any significant changes should be reported immediately to the medical team. Oxygen saturations and ECG monitoring is recommended if adrenaline is given. Before applying consider whether the risk of distress negates the accuracy of monitoring.

The effects of dexamethasone should last as croup itself is usually limited to days of symptoms. Parents need to be aware that some symptoms of respiratory distress can return, usually the following night.
This can provide a challenge — balancing upsetting the child and making the upper airway obstruction worse and performing an invasive swab. It is sensible not to swab the child whilst there is still concern about acute stridor and work of breathing.. There have been some case studies to suggest a small cohort of patients with croup who were SARS-CoV-2 positive are less responsive to the usual treatment Venn These cases may need prolonged admission due to lack of response and the need for additional supportive therapy.

Viral laryngotracheobronchitis. This inflammation causes a tell-tale cough and noisy breathing due to the obstruction to flow. There may be signs of increased work of breathing too such as sub-costal recession or a tracheal tug. They are generally quite well and are running around the waiting room!
These kids are usually between six months and four years of age, and occurs at the beginning of autumn, though this spring we are seeing a lot of cases. Children with croup may present with a preceding coryza-like illness and a low-grade fever. Boys are more commonly affected than girls, and some children seem to get it yearly. This depends on your assessment of the child. Croup is a self-limiting viral illness and treatment tends to look to short term reduction in the inflammation to improve the work of breathing.
Historically clinicians have used Westley scoring system to score croup and assess their severity before giving medication. In children who look unwellit is important to not upset them by avoiding unnecessary interventions such as excessive handling or performing an ENT exam.
If the child is able to take the medication, dexamethasone or prednisolone should be given to all cases of croup where any stridor or increased effort in breathing is present. Dexamethasone appears to be more efficacious than prednisolone.
It has an onset of action within 1 hour 30 minutes — 4 hours and has a half-life of up to hours Schimmer There has been debate overdosing with doses of 0. Ultimately, 0. If there are concerns about re-occurrence patients are occasionally sent home with an additional dose to be taken 12 hours later. There appears to be no significant clinical difference between the two different steroids in terms of the need for additional treatment or length of stay. Dexamethasone was associated with a reduction in re-attendances, which may be due to the shorter half-life of Prednisolone GatesSchimmer Nebulised budesonide 2mg stat dose is reserved for children who cannot take the dose.
This may be because it was spat ou tor because they are working too hard to breathe. A Cochrane review in shows that budesonide is not superior to dexamethasone, with Westley Croup scores better in the dexamethasone group at 6 and 12 hours compared to budesonide.
A combination of treatment does not appear to lead to additional benefit Gates In severe cases, when the child has features of severe work of breathingincluding significant recession, hypoxia or tiring, nebulised adrenaline has been used 0.
Adrenaline provides short term relief from respiratory distress and can be a bridge to getting steroids on board. The effects are short-acting and wear off after a couple of hours. In the olden days parents tried treating croup at home with steam inhalation not effective. In hospitals, humidified oxygen has also been tried though this has not been proven to be effective either Moore Heliox oxygen and helium combined has also been looked at as it may improve airflow.
The evidence is limited and safety and efficacy remain questionable More, There is no evidence that salbutamol works in croup. If they are well and the stridor has resolved, patients can be discharged home with safety-netting advice. The effects of dexamethasone should last as croup itself is usually limited to days of symptoms.

Definition Croup laryngotracheobronchitis is an upper respiratory illness characterised by a hoarse voice, barking cough, and stridor. The clinical symptoms are a result of inflammation and narrowing of the upper airway larynx, trachea and bronchi. Background Croup is most commonly caused by the Parainfluenza virus, but a variety of respiratory viruses may be responsible Symptoms are usually more prominent at night Most cases are mild and do not require admission Severe cases can be life-threatening due to potential airway compromise.
Assessment Do not upset the child — this will exacerbate the symptoms The severity of the stridor is not an indication of the severity of croup History Ask about the onset and duration of symptoms: Coryza Cough Stridor Increased work of breathing. Possibility of inhaled foreign body or anaphylaxis Past history — e. Examination It is important not to exacerbate the symptoms by upsetting the child — keep your assessment short and as non-invasive as possible.
Keep the child in their most comfortable position e. Work of breathing: Degree mild, moderate or severe Recession sternal, intercostal, subcostal, tracheal tug. Monitor for signs of impending respiratory exhaustion.
Differential diagnoses Underlying congenital abnormality eg: laryngomalacia, tracheomalacia Inhaled foreign body Anaphylaxis Epiglottitis Bacterial tracheitis. Management All children who present to Emergency Department with croup should receive corticosteroids Additional treatments depend on the severity and may include nebulised adrenaline See Croup Management Flowchart.

Initial management Severe croup is treated as above with high flow oxygen and nebulised adrenaline. Medications Corticoteroids Steroids start working by 30 minutes and reduce time in hospital, transfers to PCC, the chances of intubation for inpatients, and also reduce the likelihood of relapse after discharge home.
Steroid therapy is extremely successful in treating stridor, but does not resolve the underlying viral symptoms. A single dose of steroid is usually all that is required in mild to moderate croup.
Medication Dose Route Treatment Dexamethasone 1 0. Dexamethasone 1 0. Can give if oral steroids are not tolerated e. Adrenaline The effect of nebulised adrenaline is short lived and is thought not to change the natural history of croup. It may be repeated after 15 minutes if necessary.
