Epistaxis
BASICS
DESCRIPTION
Bleeding from nares, nasal cavity, or nasopharynx involving anterior or posterior mucosa.
Intractable epistaxis: recurrent or persistent despite packing or multiple episodes needing medical care.
Synonym: nosebleed .
EPIDEMIOLOGY
Bimodal incidence: peaks in children <15 years and adults >50 years (especially 70-79).
Most common in males <49 years.
Rare in children <2 years.
~6% require medical/surgical intervention; ~1 in 200 ER visits.
Lifetime prevalence ~60%.
ETIOLOGY AND PATHOPHYSIOLOGY
Most nosebleeds due to local causes rather than systemic disease.
Anterior (90-95%) : Kiesselbach plexus.
Posterior (5-10%) : Woodruff plexus (sphenopalatine artery branches). May present with hematemesis or hemoptysis.
Local causes:
Trauma, nose picking (epistaxis digitorum ).
Foreign bodies, septal perforation, fractures, surgery, barotrauma.
Local inflammation/infection (viral URI, sinusitis, TB, syphilis).
Irritant inhalation (smoking, cocaine, rhinitis).
Topical steroid/antihistamine overuse.
Nasal vasoconstrictor overuse.
Septal deviation, low humidity, oxygen, CPAP.
Tumors (benign/malignant), vascular malformations (e.g., post-trauma carotid aneurysm).
Systemic causes:
Thrombocytopenia, congenital/acquired coagulopathies.
Liver/renal disease, chronic alcohol abuse, leukemia.
Anticoagulant use, CHF.
Hereditary hemorrhagic telangiectasia (HHT).
Collagen disorders, mitral valve stenosis, multiple myeloma, polycythemia vera, HIV.
RISK FACTORS
Local irritation.
Medications: aspirin, clopidogrel, ginseng, garlic, ginkgo biloba, sildenafil, warfarin, other anticoagulants.
Prior septoplasty/turbinate surgery, anemia, thrombocytopenia increase recurrent risk.
GENERAL PREVENTION
Nighttime humidification.
Cut fingernails, avoid nose picking.
Spray nasal meds laterally, using opposite hand.
Use petroleum jelly to prevent mucosal drying.
COMMONLY ASSOCIATED CONDITIONS
Vascular malformations/telangiectasia (HHT).
Neoplasm (rare, suspect if persistent unilateral bleeding).
Systemic coagulopathy, cirrhosis, renal failure, alcohol misuse.
Hypertension not proven cause but may worsen bleeding control.
DIAGNOSIS
HISTORY
Assess anemia and cardiovascular compromise.
Determine side, severity, duration of bleeding.
Identify trauma (including nose picking), cocaine use.
Past episodes and frequency.
Comorbidities (cirrhosis, coagulopathies).
Medications: nasal sprays, anticoagulants, antiplatelets.
Symptoms of posterior bleeding (nausea, hematemesis, hemoptysis).
PHYSICAL EXAM
Airway patency and cardiovascular stability.
Localize bleeding site (anterior vs posterior).
Use nasal speculum and good light with patient upright/semi-upright.
Patient leans forward and pinches nose between exams.
DIFFERENTIAL DIAGNOSIS
Usually clear clinically.
Include posterior bleeding as differential in chronic blood loss.
DIAGNOSTIC TESTS
Labs/imaging not usually needed if bleeding controlled easily.
Initial tests
No labs for mild responsive cases.
For recurrent/intractable: CBC, PT/PTT, BMP, cross-match, toxicology if illicit nasal drugs suspected.
Follow-up and special tests
Evaluate neoplasia if recurrent unilateral bleeding.
Nasal endoscopy.
SPECIAL POPULATIONS
Pediatric: more likely anterior, idiopathic, recurrent.
Geriatric: more likely posterior bleeding.
TREATMENT
OUTPATIENT
Most cases managed outpatient.
Home treatment: Nosebleed QR powder (hydrophilic polymer + potassium salt) promotes scab.
Apply direct pressure (pinch nasal ala) 5-20 min without break stops most bleeds.
Clear clots by nose blowing.
Ice pack over nose dorsum aids hemostasis.
Inspect septum for bleeding site.
GENERAL MEASURES
Resuscitation as needed; ABC approach.
MEDICATION
First Line
Topical vasoconstrictors:
Oxymetazoline 0.05%
Phenylephrine 0.5-1%
Epinephrine 1:1000
Cocaine 4%
Second Line
Chemical (silver nitrate) or electrical cautery.
Nasal packing: ribbon gauze, nasal tampons, balloon catheters.
Refractory: surgical ligation, endoscopic ligation/cautery, endovascular embolization.
ISSUES FOR REFERRAL
Posterior bleeds often need ENT consult.
Anterior bleeds refractory to conservative, packing, cautery.
Recurrent epistaxis.
HHT patients require ENT follow-up.
Concurrent anticoagulation management:
Therapeutic INR with bleeding stop: continue same warfarin dose.
Supratherapeutic INR: manage accordingly.
Persistent bleeding: stop anticoagulants, give vitamin K, PCC as needed.
Novel anticoagulants: less epistaxis but harder to control when it occurs.
ADDITIONAL THERAPIES
Nasal packing with ribbon gauze or nasal tampons.
Routine systemic antibiotics unnecessary; topical may be effective and cheaper.
Floseal (thrombin gel): better tolerated, more effective than packing.
Local tranexamic acid reduces bleeding time versus anterior packing.
Silver nitrate cautery for active anterior septal bleeding (75% concentration preferred).
Limit cautery to one septal side; wait 4-6 weeks between treatments to prevent perforation.
Posterior packing with balloon devices (e.g., Foley catheter).
Hospital monitoring generally required for posterior packing.
SURGERY/OTHER PROCEDURES
Packing for anterior bleed
Vaseline ribbon gauze layering from floor upward.
Ends of ribbon gauze protrude outside nostril; secure with external gauze.
Nasal tampon lubricated with KY jelly or antibiotic ointment.
Merocel and Rapid Rhino packs easier and better tolerated.
Packing for posterior bleed
Foley catheter or specialized balloon inserted through nose to posterior oropharynx.
Balloon inflated (e.g., 10 mL saline), traction maintained with padded umbilical clamp.
ADMISSION AND NURSING CONSIDERATIONS
Hospitalize elderly, posterior bleeding, coagulopathy, or significant comorbidities.
Admission indications: posterior bleed, intractable vomiting, hemodynamic instability, clotting disorders.
Universal ABC approach; stop bleeding.
ONGOING CARE
FOLLOW-UP
Hemodynamic monitoring if severe blood loss.
Nasal packing left in place at least 24 hours (some recommend 3-5 days).
Rebleeds often occur 24-48 hours after removal.
Longer packing duration risks mucosal injury and toxic shock syndrome.
PATIENT EDUCATION
Teach proper nose pinching technique.
Avoid trauma or irritants.
Manage systemic illnesses and medication compliance.
PROGNOSIS
Most epistaxis self-limited.
Good outcomes with appropriate treatment.
COMPLICATIONS
Septal perforation.
Pressure necrosis of nasal mucosa.
Toxic shock syndrome (with packing).
Arrhythmias (especially with posterior packing).

CLINICAL PEARLS
Most epistaxis is anterior and responds well to pressure over anterior nares for 5-20 minutes.
Most nosebleeds are idiopathic or due to digital trauma (nose picking) .
Posterior bleeds may be asymptomatic or present with nausea, hematemesis, or heme-positive stool .
Evaluate for neoplasm if recurrent unilateral epistaxis.
