SOAP Note

To approach this case, we'll start by creating a SOAP note, which stands for Subjective, Objective, Assessment, and Plan. Given the information, the SOAP note would look something like this:

• Subjective: A 2-year-old child presents with shortness of breath (SOB). Questions to ask include:
  • How long has the child been experiencing SOB?
  • Has the child had any recent illnesses or infections?
  • Are there any known allergies or medical conditions?
  • Has the child been exposed to anything that could cause respiratory distress (e.g., smoke, chemicals)?
• Objective:
  • Vital signs: respiratory rate, oxygen saturation, heart rate, blood pressure.
  • Physical examination findings: lung sounds, presence of wheezing, stridor, or retractions.
• Assessment: Differential diagnosis based on the history and physical examination.
• Plan: Further diagnostic tests and management based on the differential diagnosis.

Differential Diagnosis

Given the presentation of a 2-year-old with shortness of breath, the differential diagnosis can be categorized as follows:

• Single Most Likely Diagnosis
  • Viral lower respiratory tract infection (e.g., bronchiolitis): This is a common cause of respiratory distress in young children, often caused by respiratory syncytial virus (RSV).
• Other Likely Diagnoses
  • Asthma: Although less common in very young children, asthma can cause episodic SOB, wheezing, and cough.
  • Pneumonia: Bacterial or viral pneumonia can cause SOB, fever, and cough in children.
  • Foreign body aspiration: This is a common emergency in toddlers, who often put objects in their mouths, which can lead to airway obstruction.
• Do Not Miss Diagnoses
  • Epiglottitis: Although rare, it's a life-threatening condition that requires immediate recognition and treatment. It presents with severe respiratory distress, stridor, and difficulty swallowing.
  • Congenital heart disease: Certain congenital heart defects can present with respiratory symptoms due to pulmonary congestion or other complications.
  • Pneumothorax: Air in the pleural space can cause sudden onset of SOB and is a medical emergency.
• Rare Diagnoses
  • Cystic fibrosis: A genetic disorder that leads to persistent lung infections and progressive reduction in lung function.
  • Interstitial lung disease: A broad category of diseases that affect the lung tissue and can cause SOB among other symptoms.
  • Tumor or cyst causing airway obstruction: Rarely, tumors or cysts can compress or obstruct the airways, leading to respiratory distress.

Each of these diagnoses has a different set of risk factors, clinical presentations, and diagnostic approaches. A thorough history, physical examination, and appropriate diagnostic tests (such as chest X-rays, blood gases, and pulmonary function tests when applicable) are crucial for making an accurate diagnosis and guiding management.
