Coughing is a reflex action with the essential role of keeping the airways clear of irritants and preventing unwanted substances from reaching the lungs. This mechanism involves the expulsion of particles, which might include mucus-containing phlegm or, less commonly, blood. Coughs can be classified as either productive, meaning they produce phlegm or blood, or non-productive (dry coughs), which do not.

In terms of dealing with expelled content, practices vary by age: older children and adults are likely to spit out whatever is brought up, whereas it is not uncommon for younger children to swallow it.

Coughing is a common symptom among children and frequently propels parents to seek medical advice. It's a symptom healthcare professionals should thoroughly evaluate and parents should carefully observe.

Deciphering the Cough: Causes and Concerns

The genesis of a cough can be complex, influenced by both its duration—acute meaning less than four weeks, and chronic being four weeks or longer—and its nature.

Common Causes

  • Acute coughs are often triggered by viral upper respiratory infections.
  • Chronic coughs may typically be attributed to conditions like asthma, gastroesophageal reflux, or postnasal drip.

Uncommon Causes

Acute coughs might also arise from aspiration of foreign objects, or less common respiratory infections such as pneumonia, pertussis, or tuberculosis. Chronic coughs can be reflective of underlying genetic disorders, congenital malformations in the respiratory system, chronic inflammatory issues, or even stress-related factors (habit cough or psychogenic cough).

Clinical Assessment of Pediatric Cough

Not every cough necessitates an immediate visit to the doctor’s office. Recognizing signs that may signal a severe underlying issue is crucial for caregivers.

Warning Signs

Some symptoms accompanying a cough demand more urgent medical attention, such as:

  • Bluish skin or lips (cyanosis)
  • A noticeable high-pitched whistling sound during breathing (stridor)
  • Breathing difficulty
  • An overall sick appearance
  • Repetitive uncontrollable coughing spasms followed by a sharp intake of breath (whooping cough-like symptoms)

When to See a Doctor

Children exhibiting these warning signs should be promptly seen by a physician or taken to an emergency department, especially if there is a suspicion of foreign body inhalation. For those without urgent signs but experiencing severe or harsh coughs, contacting a physician is advised. Whether assessments occur on the same day or the next is determined by the child’s age, other symptoms, and medical history. Conversely, in a generally healthy child with infrequent coughs and common cold symptoms, medical consultation might not be necessary.

Children with chronic cough without warning signs should still see a doctor, though a short waiting period is generally safe.

The Physician’s Approach

The first step for physicians is to gather a thorough patient history and conduct a physical examination. Factors such as the cough's timing, its triggering factors, its sound, associated symptoms, and whether it produces phlegm or blood help narrow down potential causes.

Nighttime coughs might be related to asthma or postnasal drip; whereas a rough cough might indicate croup or a lingering cough from a viral upper respiratory infection. A sudden cough in an otherwise symptom-free child raises concern for foreign body aspiration.

A detailed physical examination, including auscultation of the chest, is fundamental. When examining a child between 6 months and 6 years old, physicians inquire about possible foreign body ingestion—anything from small toys to food items.

Diagnostic Testing

For children displaying warning signs, tests such as pulse oximetry and chest x-rays are common. Additional tests are tailored based on clinical findings. Typically, in children without warning signs, extensive testing is not immediately pursued if a cough has persisted less than four weeks and is accompanied by common cold symptoms. However, if certain infections such as COVID-19 are a concern, testing may be more readily pursued.

Addressing Pediatric Cough

Treatment strategies center on addressing the underlying cause, with remedies ranging from antibiotics for bacterial pneumonia to antihistamines for allergic rhinopharyngitis.

To ease cough symptoms, traditional remedies have been used, like ensuring the child breathes humidified air and stays well-hydrated. While these methods are safe, their efficacy is not robustly supported by scientific evidence. However, for children over a year old, honey (pure or diluted) can be an effective cough suppressant.

Cough and cold medicines, including dextromethorphan and codeine, are not typically recommended for children due to the importance of cough in clearing airways and potential side effects. Mucolytics, designed to thin and loosen mucus, are also generally not advised for children.

Key Takeaways

- A clinical examination is usually decisive in identifying the cough's cause.
- For young children, the possibility of a foreign body aspiration should be considered.
- Chest x-rays are warranted for children with alarming symptoms or when a cough surpasses a four-week duration.
