Epiglottitis

Epiglottitis is a rapidly progressive and potentially life-threatening inflammation and swelling of the epiglottis and surrounding supraglottic structures. This inflammation can quickly lead to complete airway obstruction, making it a medical emergency. While historically more common in children, particularly those unvaccinated against Haemophilus influenzae type b (Hib), it can affect individuals of all ages, including adults. Prompt diagnosis and emergent airway management are crucial for a positive outcome.

The primary cause of epiglottitis is infection, most commonly bacterial.
Bacterial: Haemophilus influenzae type b (Hib): Historically the most common cause in children, significantly reduced by vaccination. Streptococcus pneumoniae*: Leading cause in both vaccinated children and adults.
Group A Streptococcus (S. pyogenes) Staphylococcus aureus (including MRSA) Klebsiella pneumoniae, Pseudomonas aeruginosa*

• Viral: Herpes simplex virus (HSV), Varicella-zoster virus (VZV)

• Direct trauma to the throat

The inflammation in epiglottitis primarily affects the epiglottis, aryepiglottic folds, and arytenoids, which are part of the supraglottic larynx. Bacterial or other insults trigger an intense inflammatory response, leading to rapid edema and swelling of these tissues. The epiglottis, which normally acts as a flap to cover the trachea during swallowing, becomes severely swollen and can obstruct the glottic opening. This swelling narrows the airway lumen, increasing resistance to airflow and ultimately leading to respiratory distress. In severe cases, the airway can become completely occluded, resulting in hypoxia, hypercapnia, and ultimately respiratory arrest. The edema can progress very quickly, making early intervention critical.

Before the widespread adoption of the Hib vaccine, epiglottitis predominantly affected children aged 2-7 years. The incidence in children has dramatically decreased by over 95% in developed countries. However, epiglottitis still occurs, primarily in:

• Unvaccinated or under-vaccinated children.

• Gender: Males are slightly more affected than females across all age groups.

Lack of Haemophilus influenzae type b* (Hib) vaccination

• Immunocompromised state (e.g., HIV/AIDS, cancer, transplant recipients, chemotherapy)


• Diabetes mellitus (in adults)


• Male gender


• Age (children 2-7 years, adults 40-60 years)


• Trauma to the throat or recent upper respiratory tract infection


• Chronic medical conditions (e.g., hypertension, obesity)


• Geographic factors: Higher incidence in developing countries where vaccination rates may be lower.

A. Early Symptoms

• Sudden onset of severe sore throat


• Difficulty swallowing (dysphagia)


• Low-grade fever B. Common Symptoms


• Drooling (due to inability to swallow secretions)


• Muffled or "hot potato" voice


• Inspiratory stridor (high-pitched crowing sound on inhalation)


• Tripod position (sitting upright, leaning forward, chin extended to maximize airway opening)


• Increased anxiety and restlessness


• Tachypnea (rapid breathing) C. Advanced Symptoms


• Retractions (supraclavicular, intercostal)


• Cyanosis (bluish discoloration of skin/mucous membranes)


• Altered mental status (irritability, lethargy)


• Weak or absent cry (in children) D. Emergency Symptoms


• Severe respiratory distress


• Complete airway obstruction


• Loss of consciousness


• Respiratory arrest


• Cardiac arrest

• Vital Signs: Fever, tachypnea, tachycardia, potentially hypoxemia.
• Inspection: Observe for drooling, tripod position, muffled voice, inspiratory stridor, signs of respiratory distress (retractions, nasal flaring). Pallor or cyanosis may be present. Avoid direct visualization of the oropharynx with a tongue depressor if epiglottitis is suspected, as this can precipitate laryngospasm and complete airway obstruction.
• Palpation: Cervical lymphadenopathy may be present.
• Auscultation: Diminished breath sounds, inspiratory stridor.

A. Clinical Assessment
Based on rapid onset of characteristic symptoms (sore throat, dysphagia, drooling, muffled voice, stridor, tripod position) and physical findings. This is often sufficient for presumptive diagnosis and emergent airway management. B. Laboratory Testing
Blood tests can help identify the causative agent and assess the severity of infection. C. Imaging Studies
Lateral neck X-ray can be performed safely if the patient is stable and a medical team is present to manage potential airway compromise. Definitive diagnosis often made via direct laryngoscopy. D. Functional Tests
Not typically used for diagnosis. E. Biopsy Findings
Not performed for diagnosis. Swabs may be taken from the epiglottis during intubation for culture. F. Genetic Testing
Not applicable for epiglottitis. G. Differential Diagnosis
Croup, bacterial tracheitis, retropharyngeal abscess, peritonsillar abscess, foreign body aspiration.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: To assess for signs of infection and systemic inflammatory response.
Expected Findings: Leukocytosis (elevated white blood cell count) with a left shift (increased neutrophils and immature forms).
Interpretation: Suggests bacterial infection. Blood Cultures
Type: Blood Test
Purpose: To identify the specific bacterial pathogen causing the infection and guide antibiotic selection.
Expected Findings: Positive culture for specific bacteria (e.g., H. influenzae, S. pneumoniae).
Interpretation: Confirms bacterial etiology and guides targeted antimicrobial therapy. Epiglottic Swab/Culture
Type: Swab (obtained during laryngoscopy/intubation)
Purpose: To identify the specific bacterial pathogen directly from the inflamed epiglottis.
Expected Findings: Positive culture for specific bacteria.
Interpretation: Provides direct evidence of bacterial infection in the epiglottic region.

Lateral Neck X-ray
Purpose: To visualize the supraglottic structures and assess for swelling.
Typical Findings: "Thumb sign" – an enlarged, edematous epiglottis resembling a thumb, protruding into the airway. Effacement of the vallecula.
Clinical Importance: Can support the diagnosis of epiglottitis in a stable patient, differentiating it from other causes of stridor. It's crucial that this is performed with airway management personnel and equipment readily available. Flexible Fiberoptic Laryngoscopy
Purpose: To directly visualize the epiglottis and surrounding structures.
Typical Findings: Severely erythematous, cherry-red, swollen epiglottis; edematous aryepiglottic folds.
Clinical Importance: The definitive diagnostic test, but carries a risk of precipitating acute airway obstruction, especially in children. Usually performed in a controlled environment like an operating room by an experienced clinician (anesthesiologist, ENT surgeon) prepared for immediate intubation.

• Croup (Laryngotracheobronchitis): More common in younger children, typically preceded by viral URI, presents with a "barking" cough, hoarseness, and milder inspiratory stridor. No drooling or severe dysphagia. X-ray shows "steeple sign" (subglottic narrowing).
• Bacterial Tracheitis: Similar to croup but more severe. Presents with a high fever, toxic appearance, thick purulent tracheal secretions, and unresponsive to standard croup treatments.
• Retropharyngeal Abscess: Presents with fever, dysphagia, neck stiffness, and muffled voice. Can cause airway compromise. Lateral neck X-ray and CT scan are diagnostic.
• Peritonsillar Abscess: Severe unilateral sore throat, dysphagia, "hot potato" voice, trismus. Uvular deviation is common.
• Foreign Body Aspiration: Sudden onset of choking, coughing, stridor, or respiratory distress, often without fever.

• Acute Airway Obstruction: The most severe and life-threatening complication.
• Respiratory Arrest: Consequence of unmanaged airway obstruction.
• Hypoxia/Hypercapnia: Due to inadequate ventilation.
• Pneumonia: Aspiration or direct extension of infection.

• Septic Arthritis: Hematogenous spread of bacteria.
• Pericarditis: Rare, but can occur from systemic spread.
• Death: If airway is not secured promptly.

A. Lifestyle Modifications
Not applicable. B. Preventive Measures
Vaccination: Haemophilus influenzae type b* (Hib) vaccine is the most effective preventive measure, especially in children. C. Medical Treatment

• Antibiotics: Intravenous broad-spectrum antibiotics are initiated immediately after securing the airway, targeting common pathogens. Examples: Ceftriaxone or Cefotaxime (third-generation cephalosporins). If MRSA is suspected, Vancomycin may be added. Once cultures return, therapy can be narrowed.


• Corticosteroids: Often used, but their efficacy in epiglottitis is debated. Dexamethasone is commonly administered to reduce inflammation and edema.


• Oxygen Therapy: Supplemental oxygen should be provided immediately to hypoxic patients. D. Surgical Treatment


• Tracheostomy: Performed if endotracheal intubation is unsuccessful or contraindicated, providing a definitive surgical airway. E. Interventional Procedures


• Endotracheal Intubation: The cornerstone of emergency management. Performed in a controlled environment (e.g., operating room) by an experienced professional (anesthesiologist, ENT surgeon) prepared for difficult airway. A smaller than usual endotracheal tube may be needed due to severe swelling. Extubation usually occurs after 2-3 days when swelling has resolved. F. Rehabilitation

• Secure Airway Immediately: The absolute priority. Do not delay.


• Maintain Calm Environment: Minimize agitation, especially in children, as crying can worsen airway obstruction.


• Avoid Oral Examination: Do not attempt to visualize the epiglottis with a tongue depressor outside of a controlled setting.


• Preparation for Intubation: Ensure experienced personnel, equipment for intubation, and emergency tracheostomy are readily available.


• Oxygen & Monitoring: Provide supplemental oxygen and continuous monitoring of vital signs.

With prompt recognition, emergent airway management (typically intubation), and appropriate antibiotic therapy, the prognosis for epiglottitis is excellent, with full recovery expected. Mortality rates have dramatically decreased with modern management, estimated at less than 1%. However, without timely intervention, acute airway obstruction can lead to severe hypoxia, respiratory arrest, and death.

Primary Prevention: Hib Vaccination: The most effective preventive measure for childhood epiglottitis. Complete the recommended series of Haemophilus influenzae type b vaccine according to national immunization schedules.
Secondary Prevention: No specific screening programs for epiglottitis beyond general public health awareness of vaccination and prompt medical attention for suspicious symptoms.
