Ep 26 - Intro to EM: The ED approach to the child with shortness of breath

Managing Shortness of Breath in Pediatric Patients: A Comprehensive Guide Welcome to the St. Emlins blog. I’m Iain Beardsell, and I’m joined by our resident pediatric expert, Natalie May. Today, we’re discussing a challenging but crucial topic for those in Emergency Medicine: managing pediatric patients with shortness of breath. Understanding Pediatric Shortness of Breath Shortness of breath in children is a frequent and often intimidating presentation in the emergency department, especially during winter. This guide aims to provide a systematic approach to assess and manage these young patients effectively. Initial Assessment: Stay Calm and Structured When managing a child with shortness of breath, it's essential to stay calm and use a structured approach: Level of Consciousness: Determine if the child is alert or needs immediate resuscitation. Breathing Effort: Look for signs of respiratory distress such as the use of accessory muscles, intercostal and subcostal recession, tracheal tug, or head bobbing in infants. Breathing Efficacy: Listen for extra sounds like wheezes or stridor to identify the underlying pathology. Oxygen Delivery: Check the child's oxygen saturation, level of consciousness, and heart rate to evaluate breathing effectiveness. Oxygen Administration: A Safe First Step Administering oxygen is a safe and effective initial treatment for children with shortness of breath. It is unlikely to cause harm and can be crucial for stabilizing the patient while further assessments are made. Detailed History and Physical Examination Gathering a detailed history from the parents is essential: Chronology of Events: Determine how long the child has been short of breath. Pre-existing Conditions: Ask about any previous lung problems. Additional Symptoms: Note any associated symptoms like fever or cough. Inhaled Foreign Body: Consider this, especially if the onset of symptoms was sudden. This information helps in deciding the appropriate therapy and whether the child needs hospital admission. Common Causes of Pediatric Shortness of Breath 1. Bronchiolitis and Viral Wheeze Bronchiolitis is a common winter illness in children under two, often caused by respiratory syncytial virus (RSV). Key signs include: Respiratory distress with significant use of accessory muscles. Wheezing and low oxygen saturation. History of recent cold symptoms in the family. Viral Wheeze often presents similarly but occurs in slightly older children. Differentiating between bronchiolitis and viral wheeze involves assessing the severity and duration of symptoms. Management: Oxygen: Provide supplemental oxygen if saturation levels are low. Bronchodilators: Trial with salbutamol through a spacer or nebulizer can be beneficial. Steroids: Generally avoided in children under five unless there is a formal asthma diagnosis or previous steroid-responsive episodes. Admission Criteria: Severe respiratory distress. Persistent low oxygen saturation. Poor feeding and hydration status. History of prematurity or chronic lung disease. 2. Croup Croup is another common viral illness presenting with a characteristic seal-like barky cough and inspiratory stridor. It often worsens at night, causing significant distress to both the child and the parents. Management: Dexamethasone: A single oral dose (0.15-0.6 mg/kg) is effective in reducing airway inflammation and improving symptoms. Observation: Monitor the child for 2 hours post-treatment to ensure improvement. Calm Environment: Minimize distress and avoid unnecessary interventions that might exacerbate symptoms. Safety Netting: Provide parents with clear instructions on when to return to the hospital, especially if symptoms worsen during the night. 3. Bacterial Infections: Pneumonia Though less common than viral infections, bacterial pneumonia should be considered, particularly if the child presents with: Fever. Persistent cough. Decreased oxygen saturation. Subtle respiratory distress. Management: Chest X-ray:
