Respiratory Emergencies

  • Epiglottitis: A potentially life-threatening condition characterized by severe sore throat, dysphagia, high fever, drooling, and respiratory distress. Immediate management includes securing the airway and providing intravenous antibiotics.
  • Croup: Common viral infection causing barking cough, stridor, and respiratory distress. Supportive care with humidified oxygen and nebulized epinephrine is the mainstay of treatment.
  • Bronchiolitis: Often caused by respiratory syncytial virus (RSV) infection, bronchiolitis presents with wheezing, cough, and respiratory distress. Management includes supportive care, oxygen therapy, and nebulized bronchodilators if indicated.

Cardiovascular Emergencies

  • Congenital Heart Disease (CHD): Various CHDs may present as emergencies, such as cyanotic spells in Tetralogy of Fallot or hypoplastic left heart syndrome. Prompt referral to a pediatric cardiologist is essential for further evaluation and management.
  • Myocarditis: Inflammation of the heart muscle leading to congestive heart failure, arrhythmias, and cardiogenic shock. Management includes supportive care, diuretics, inotropes, and antiviral therapy if indicated.
  • Kawasaki Disease: A systemic vasculitis primarily affecting children, presenting with fever, conjunctivitis, strawberry tongue, rash, and coronary artery aneurysms. Treatment involves intravenous immunoglobulin and aspirin.

Neurologic Emergencies

  • Seizures: Children may experience febrile seizures or non-febrile seizures requiring immediate management with antiepileptic drugs and addressing the underlying cause.
  • Meningitis: Bacterial or viral infection causing meningeal inflammation. Symptoms include fever, headache, neck stiffness, and altered mental status. Lumbar puncture for cerebrospinal fluid analysis and initiation of appropriate antibiotics are crucial.
  • Head Trauma: Prompt evaluation and management of head trauma, including assessment of the Glasgow Coma Scale, imaging studies, and neurosurgical consultation if necessary.

Gastrointestinal Emergencies

  • Intussusception: Telescoping of one part of the intestine into another, causing abdominal pain, currant jelly-like stools, and a palpable abdominal mass. Air enema or surgical intervention is necessary for reduction.
  • Malrotation with Volvulus: Abnormal rotation of the intestines leading to obstruction and compromised blood supply. Surgical intervention is urgent to prevent bowel necrosis.
  • Acute Appendicitis: Inflammation of the appendix requiring surgical removal. Clinical presentation includes periumbilical pain migrating to the right lower quadrant, fever, and leukocytosis.

Infectious Emergencies

  • Sepsis: Systemic inflammatory response to infection, often caused by bacteria. Early recognition, initiation of broad-spectrum antibiotics, fluid resuscitation, and management of septic shock are vital.
  • Pneumonia: Infection of the lungs presenting with fever, cough, tachypnea, and respiratory distress. Treatment includes appropriate antibiotics, oxygen therapy, and supportive care.
  • Urinary Tract Infections (UTIs): Commonly caused by bacteria, UTIs may present with fever, dysuria, and abdominal pain. Early diagnosis and appropriate antibiotic therapy are crucial to prevent renal complications.
