A Comprehensive Guide to Paediatric Cough Management in Pakistan 

Cough is one of the most common symptoms that leads to paediatric consultations worldwide, including in Pakistan. While often benign, it can also indicate serious underlying conditions. This article provides a comprehensive summary of the treatment guidelines for paediatric cough. It is crucial for healthcare providers to adhere to these guidelines to ensure effective and safe treatment for children.

Understanding Cough: A Scientific Overview

Cough is a protective reflex that clears the airways of irritants, such as mucus, foreign particles, or microbes. Scientifically, the cough reflex is initiated when sensory nerves in the respiratory tract, particularly the larynx, trachea, and bronchi, are stimulated. This stimulation sends signals to the cough centre in the brainstem, which then triggers a series of coordinated muscle actions, resulting in the expulsion of air from the lungs.

The cough reflex is vital for protecting the respiratory system from potential harm. However, when persistent or chronic, it can be a source of distress, especially in children. Understanding the types and causes of cough is essential in determining the appropriate treatment options.

The Prevalence of Paediatric Cough

Cough is a common symptom among children, often associated with respiratory tract infections. In Pakistan, the prevalence of cough among children is significant, contributing to a substantial burden on healthcare systems. Cough can significantly impact a child’s quality of life, affecting their sleep, appetite, and overall well-being. Moreover, persistent cough can be a sign of underlying medical conditions, necessitating prompt evaluation and treatment.

Paediatric cough is a significant concern for both parents and healthcare providers. According to a study published in the Journal of Pediatric Child Health, cough is one of the most frequent reasons for children visiting outpatient clinics. The high prevalence of cough-related visits highlights the importance of following evidence-based guidelines to manage this symptom effectively.

Types of Paediatric Cough

Understanding the different types of paediatric cough is crucial for accurate diagnosis and treatment. The main types include acute cough, acute prolonged cough, chronic cough, specific cough, and non-specific cough. Each type has distinct characteristics, causes, and treatment approaches.

1. Acute Cough

An acute cough is defined as a cough lasting less than three weeks. It is usually associated with respiratory tract infections, such as the common cold or influenza. Acute cough is typically diagnosed based on clinical history and physical examination.

Causes:

The most common cause of acute cough in children is viral respiratory tract infections, such as the common cold. Bacterial infections, such as streptococcal pharyngitis, can also cause acute cough, but these are less common.

Treatment:

Treatment for acute cough is primarily supportive. Rest, hydration, and the use of antipyretics, such as paracetamol, are recommended. Cough suppressants are generally not recommended in children due to the lack of evidence for their efficacy and potential side effects.

2. Acute Prolonged Cough

Acute prolonged cough lasts between three to eight weeks. It is often a continuation of an acute cough that has not resolved. Diagnosis may require further investigation, including chest X-rays or referral to a specialist if the cough persists beyond this period.

Causes:

Post-viral cough is the most common cause of acute prolonged cough. Other causes include pertussis (whooping cough), acute bronchiolitis, rhinosinusitis,  and persistent bacterial bronchitis (PBB). 

Treatment:

Management is similar to acute cough, with a focus on treating any underlying infection and monitoring for potential complications. Antibiotics may be considered in cases of bacterial infections, such as pertussis, but their use should be based on clinical guidelines.

3. Chronic Cough

Chronic cough is defined as a cough lasting longer than eight weeks. It is a concerning symptom that often requires a detailed evaluation to determine the underlying cause.

Causes:

The causes of chronic cough in children are diverse and can include asthma, gastroesophageal reflux disease (GERD), and chronic rhinosinusitis. Exposure to environmental irritants, such as tobacco smoke, can also contribute to chronic cough.

Treatment:

Treatment options for chronic cough depend on the underlying cause. For example, asthma-related cough may be managed with inhaled corticosteroids, while GERD-related cough may require dietary modifications and acid-suppressing medications . It is essential to address the root cause rather than just the symptom to achieve long-term relief.

4. Specific Cough

Specific cough refers to a cough with an identifiable cause, such as asthma, bronchiectasis, or a foreign body in the airway. Diagnosis typically involves a thorough history, physical examination, and targeted investigations, such as spirometry or bronchoscopy.

Causes:

Common causes of specific cough include asthma, cystic fibrosis, and inhalation of a foreign object. These conditions often require specialised care and management.

Treatment:

Treatment for specific coughs is tailored to the underlying condition. For instance, asthma management includes the use of inhaled bronchodilators and corticosteroids, while bronchiectasis may require antibiotics and physiotherapy.

5. Non-Specific Cough

Non-specific cough is a diagnosis of exclusion when no underlying cause can be identified. It is often a dry cough without significant clinical findings.

Causes:

The exact causes of non-specific cough are often unclear, but it may be related to post-viral inflammation or heightened sensitivity of the cough reflex.

Treatment:

Non-specific cough is typically managed with reassurance and monitoring. In some cases, empirical treatment with inhaled corticosteroids may be trialled, especially if asthma is suspected. However, unnecessary medication should be avoided.

Management of Paediatric Cough

The management of paediatric cough includes both pharmacological and non-pharmacological approaches. It is essential to tailor the treatment to the specific type of cough and the underlying cause.

Pharmacological Management

• Cough Suppressants: Cough suppressants, such as dextromethorphan, are generally not recommended for children, especially those under six years of age. Studies have shown that they are not more effective than placebo and can cause side effects, including drowsiness and irritability.
• Expectorants: Expectorants, such as guaifenesin, are sometimes used to help clear mucus from the respiratory tract. However, their efficacy in children is not well-established, and they are not routinely recommended in paediatric cough management.
• Bronchodilators: Bronchodilators, such as salbutamol, are used in cases where cough is associated with bronchoconstriction, such as in asthma. They help to relax the airway muscles and improve airflow.
• Corticosteroids: Inhaled corticosteroids are the mainstay of treatment for asthma-related cough. They help to reduce inflammation in the airways and prevent exacerbations. Oral corticosteroids may be used in severe cases, but their use should be carefully monitored due to potential side effects.
• Antibiotics: Antibiotics are only recommended when there is a clear bacterial infection, such as streptococcal pharyngitis or bacterial pneumonia. Overuse of antibiotics can lead to resistance and should be avoided.
• Prospan IVY Leaf Syrup: Prospan IVY Leaf Syrup is a natural herbal remedy that has been shown to be effective in treating coughs in children. It works by helping to relax the bronchial muscles and clear mucus from the respiratory tract. Prospan is a popular choice for parents looking for a safe and natural option to alleviate their child’s cough without the use of synthetic medications.

Non-Pharmacological Management

• Humidification: Using a humidifier in the child’s room can help to keep the air moist, which may reduce irritation of the airways and ease coughing. This is particularly helpful in cases of dry cough or cough associated with a common cold.
• Honey: For children over one year of age, honey can be an effective remedy for cough. Studies have shown that honey can soothe the throat and reduce coughing, particularly at night . It is important to note that honey should not be given to infants under one year due to the risk of botulism.
• Hydration: Ensuring the child is well-hydrated is essential in managing cough. Adequate fluid intake helps to thin mucus, making it easier to expel.
• Avoiding Irritants: Exposure to irritants, such as tobacco smoke, can exacerbate cough. It is crucial to create a smoke-free environment for children to prevent cough and other respiratory issues.
• Saline Nasal Drops: Saline nasal drops can help to clear nasal congestion, which can reduce postnasal drip—a common cause of cough in children.
• Warm Fluids: Offering warm fluids, such as herbal teas or warm water with honey (for children over one-year-old), can soothe the throat and help alleviate cough. Warm fluids can also help keep the child hydrated, which is essential for mucus clearance.
• Steam Inhalation: Inhalation of steam can help to moisten the airways, loosen mucus, and ease coughing. This can be done by having the child inhale steam from a bowl of hot water or taking a warm shower. However, caution is needed to prevent burns, and it is not recommended for very young children.
• Elevating the Head: For children who experience coughing at night, elevating the head while sleeping can help reduce postnasal drip and improve breathing. This can be done by slightly raising the head of the bed or using an extra pillow.
• Ginger and Turmeric: Ginger and turmeric have natural anti-inflammatory properties and have been used traditionally to alleviate cough. Ginger tea or warm turmeric milk can be given to older children as a natural remedy.

Drugs Often Used but Not Recommended

Certain medications are often used for treating paediatric cough but are not recommended due to the lack of evidence for their efficacy and potential risks. These include:

• Codeine: Codeine, an opioid cough suppressant, is not recommended for children due to the risk of respiratory depression and even death in some cases.
• Antihistamines: While first-generation antihistamines, such as diphenhydramine, are sometimes used to treat cough, they are not recommended in children due to their sedative effects and limited efficacy.
• Cough Syrups Containing Multiple Ingredients: Cough syrups that contain a combination of ingredients, such as antihistamines, decongestants, and cough suppressants, are commonly used but are not recommended for children. These products can cause a range of side effects, and there is insufficient evidence to support their effectiveness in treating paediatric cough. Moreover, the use of multiple active ingredients increases the risk of adverse reactions and accidental overdose.

Conclusion: Best Practices in Managing Paediatric Cough

Paediatric cough, while often a benign symptom of a common cold or minor respiratory infection, can sometimes indicate more serious underlying conditions. Accurate diagnosis and adherence to evidence-based guidelines are essential in managing cough effectively and safely in children.

Healthcare providers in Pakistan should focus on a comprehensive assessment of the type of cough, its duration, and associated symptoms to guide treatment. Pharmacological options should be used judiciously, with a preference for those with proven efficacy and safety in children. Non-pharmacological treatments and natural remedies like Prospan IVY Leaf Syrup can play a valuable role in managing mild to moderate coughs, particularly in cases where medication is not indicated or desired.

Ultimately, the goal is to provide relief to the child while addressing any underlying conditions and preventing complications. By following these guidelines, healthcare providers can ensure that they are offering the best care possible to their paediatric patients.
