Asthma in Children
Having trouble breathing can be terrifying for a child and extremely distressing for parents to witness.
Asthma, one of the most prevalent chronic illnesses in children, is a respiratory condition characterized by bronchial spasms, leading to breathing difficulties. According to the Centers for Disease Control and Prevention, asthma affects 4.6 million children under 18 years old.
Living with asthma can significantly impact a child’s daily life, causing disruptive symptoms that interfere with play, sports, school, and sleep. In some cases, unmanaged asthma can result in severe asthma attacks, posing a serious health risk.
Childhood asthma is a major reason for emergency department visits, hospitalizations, and missed school days.
Symptoms of Asthma in Children
Common symptoms of childhood asthma include:
- Wheezing or whistling sounds while breathing out
- Shortness of breath
- Chest congestion or tightness
- Frequent coughing that worsens during viral infections, sleep, exercise, or exposure to cold air
Asthma symptoms can vary among children and may fluctuate over time. Some children may experience only one symptom, such as a persistent cough or chest congestion.
It can be challenging to determine whether a child’s symptoms are due to asthma. Wheezing and other asthma-like symptoms can also be caused by infectious bronchitis or other respiratory issues. Therefore, it’s essential to consult with the child’s pediatrician about any symptoms. Early treatment can help manage asthma symptoms and potentially prevent future asthma attacks.
Childhood asthma may also cause:
- Difficulty sleeping due to shortness of breath, coughing, or wheezing
- Increased coughing or wheezing during cold or flu episodes
- Prolonged recovery or bronchitis following a respiratory infection
- Breathing difficulties that limit play or exercise
- Fatigue due to disrupted sleep
Asthma Attacks
An asthma attack typically starts with a trigger. Common triggers include allergies, the common cold, and specific irritants such as cigarette smoke, strong odors, dust, high ozone levels, and changes in humidity.
When a trigger occurs, the smooth muscle around the airways contracts, narrowing the airway. This narrowing, coupled with airway irritation, leads to swelling and mucus secretion, further constricting the airway.
As the airway narrows, an asthma attack ensues, characterized by a dry cough, respiratory distress, and the sensation of not being able to breathe. In severe cases, the airway constriction may be so intense that it causes a wheeze, which can sound like a musical note.
In the initial stages of an asthma attack, the wheeze is heard during exhalation. As the attack progresses, the wheeze may occur during both inhalation and exhalation.
Severe asthma attacks may manifest as wheezing only during inhalation, or in the most severe cases, there may be no audible wheezing due to extremely restricted airflow.
If wheezing occurs, even if the child has a known asthma diagnosis, it is crucial to seek immediate medical attention.
Treatment for Asthma
Unfortunately, asthma cannot be cured, and symptoms may persist into adulthood.
For immediate relief during an asthma attack, an albuterol breathing treatment is typically administered to relax the airway muscles.
Subsequently, a steroid, administered via IV, intramuscular injection, or oral medication, may be prescribed to reduce airway swelling.
If a child experiences respiratory distress with wheezing, immediate medical attention is necessary. Daytime asthma attacks can be addressed by the child’s regular physician, but if a severe attack occurs at night, the child should be taken to the nearest Emergency Department promptly.
In instances where a parent is alone with a child experiencing a severe asthma attack, calling 911 is recommended, as it can be challenging to drive safely while attending to a child struggling to breathe.
Preventing Asthma Attacks
Careful planning and avoiding asthma triggers are key to preventing asthma attacks.
Understanding the triggers is essential. If a parent knows specific allergens that trigger their child’s asthma, they should take steps to avoid them.
Parents should strictly prohibit smoking around their child, as exposure to tobacco smoke during infancy is a significant risk factor for childhood asthma and can trigger asthma attacks.
Encouraging the child to stay active, provided their asthma is well-managed, can help improve lung function.
During allergy seasons, daily medications can help control allergic reactions, and inhaled steroids may reduce chronic inflammation for some individuals.
For children whose asthma is triggered by dust, regular cleaning and monthly replacement of air filters are recommended.
Maintaining a healthy weight is crucial, as being overweight can exacerbate asthma symptoms and increase the risk of other health issues.
Managing heartburn effectively is important, as severe heartburn can worsen asthma symptoms. Prescription or over-the-counter medications may be necessary to control acid reflux.
If avoiding triggers and using an inhaler are insufficient in controlling a child’s asthma attacks, further treatment may be needed. The child’s pediatrician may refer them to a specialist, such as a pulmonologist or allergist, for additional treatment and prevention strategies.
