Definition And Epidemiology

  • Defined as bleeding from nostril, nasal cavity, or nasopharynx warranting medical care.
  • Includes severe, persistent, or recurrent bleeding affecting quality of life.
  • Recurrent epistaxis defined as five or more episodes per year.
  • Accounts for 0.5% of pediatric emergency department visits.
  • Peak presentation occurs between 2 and 10 years of age.
  • Rare in infants under 2 to 3 years of age; incidence is 1 per 10,000.
  • Declines in incidence after puberty.
  • More frequent during winter months due to dry air.

Anatomy And Pathophysiology

  • Most common bleeding site is anterior nasal septum.
  • Area known as Kiesselbach plexus or Little’s area.
  • Region features convergence of internal carotid branches (anterior and posterior ethmoid arteries) and external carotid branches (sphenopalatine and terminal internal maxillary arteries).
  • Superficial mucosal location makes vessels highly vulnerable to mechanical and chemical insults.
  • Posterior bleeding arises from posterior sphenopalatine branches, Woodruff plexus, and venous sources.

Etiology And Risk Factors

  • Classified clinically as primary (idiopathic) or secondary (identifiable cause).
CategorySpecific Causes
PrimaryIdiopathic
Local TraumaDigital manipulation (nose picking), facial trauma, septal perforation
Inflammation & InfectionUpper respiratory tract infections, allergic rhinitis, sinusitis, foreign body, nasal diphtheria
Neoplasms & MassesNasal polyps, juvenile nasopharyngeal angiofibroma, rhabdomyosarcoma
Hematologic & CoagulopathiesHemophilia, von Willebrand disease, leukemia, immune thrombocytopenia, platelet dysfunction, aplastic anemia, liver disease
MedicationsAnticoagulants, nasal steroid sprays, aspirin, nonsteroidal anti-inflammatory drugs
Vascular AnomaliesHemangiomas, hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome)
Systemic ConditionsHypertension, pertussis, renal failure

Age-Specific Etiology

  • Children over 2 years: Primarily local factors (trauma, mucosal drying, infections) or systemic clotting disorders.
  • Children under 2 years: Requires intensive workup for child abuse, intentional trauma, or severe hematological illness.

Clinical Presentation And Differential Diagnosis

  • Occurs without warning; blood flows slowly but freely from nostrils.
  • Bleeding often follows physical exercise in children with nasal lesions.
  • Nighttime bleeding often swallowed; manifests later as hematemesis or melena.
  • Posterior epistaxis presents with copious bleeding; mimics upper gastrointestinal source.
  • Unilateral foul-smelling discharge suggests foreign body.
  • Profuse, recurrent unilateral bleeding in adolescent males strongly suggests juvenile nasopharyngeal angiofibroma.

Assessment And Evaluation

  • Initial stabilization mandates immediate evaluation of airway obstruction and circulatory imbalance.

Clinical History

  • Document onset, duration, frequency, and laterality of bleeding.
  • Estimate blood loss objectively.
  • Inquire regarding easy bruising, bleeding from other sites, or family history of bleeding disorders.
  • Elicit history of antithrombotic medications, recreational drugs, or nasal steroid sprays.

Physical Examination

  • Assess vitals for tachycardia and hypotension.
  • Inspect skin for pallor, jaundice, petechiae, purpura, and telangiectasias.
  • Evaluate central nervous system for vision or hearing changes associated with nasopharyngeal masses.
  • Palpate abdomen for hepatosplenomegaly signifying malignancy or liver disease.
  • Perform anterior rhinoscopy using otoscope with wide-tipped speculum.
  • Clear purulent secretions and blood clots to visualize bleeding point.
  • Identify transverse nasal crease or Dennie-Morgan folds indicating allergic rhinitis.
  • Refer to otolaryngologist for flexible endoscopic evaluation if bleeding point remains unidentified.

Investigations

  • Usually self-limited; potentially life-threatening episodes require detailed evaluation.
  • Perform full blood count, urgent blood grouping, cross-matching, and coagulation studies for recurrent, prolonged, or significant bleeding.
  • Screen for von Willebrand disease in patients with familial bleeding history; standard coagulation profiles may appear normal.

Management

Immediate Resuscitation And First Aid

  • Position upright leaning slightly forward; prevents blood aspiration or swallowing.
  • Apply firm, constant pressure on caudal soft nose for 5-10 minutes.
  • Avoid pinching bony nasal bridge; provides inadequate pressure.
  • Apply cold compresses to nose.
  • Instruct patient to gently blow nose to evacuate fibrinolytic blood clots if bleeding persists after initial compression.

Pharmacological And Local Therapy

  • Administer topical vasoconstrictors (oxymetazoline or phenylephrine 0.25-1%); reapply pressure.
  • Cauterize identified anterior bleeding points with topical silver nitrate.
  • Avoid simultaneous bilateral septal cauterization; prevents septal perforation.
  • Utilize bipolar electrocautery for recurrent epistaxis as alternative to chemical cautery.

Nasal Packing

  • Insert anterior nasal pack using absorbable hemostatic agent if pressure and cautery fail.
  • Retain anterior packing for 24-48 hours.
  • Utilize combined anterior and posterior packing for uncontrolled posterior bleeds.
  • Consult otolaryngologist for posterior bleeding management.

Surgical And Advanced Interventions

  • Consider minimally invasive transnasal endoscopic sphenopalatine artery ligation for severe, unremitting epistaxis.
  • Utilize endovascular embolization to occlude feeding vessels in patients with sinonasal tumors.
  • Avoid embolization of ethmoidal arteries; derivation from ophthalmic artery carries blindness risk.
  • Administer blood transfusions and specific factor replacement for severe hemorrhage with underlying coagulopathy.

Prevention

  • Discourage digital manipulation and nose picking.
  • Maintain proper room humidification during dry winter months.
  • Apply petrolatum ointment to nasal septum; increases moisture and prevents fissuring.
  • Treat underlying allergic rhinitis and nasal infections promptly.
  • Discontinue offending medications such as nasal steroid sprays if implicated.
