Epistaxis By Stacey Singer-Leshinsky R-PAC
Function of the Nose • Vasculature just under the mucosa. • Vasculature supply originates from the ethmoid branches of the internal carotid arteries and the facial and internal maxillary divisions of the external carotid arteries. • Nose bleeds are very common
Epistaxis • Acute hemorrhage from the nostril, nasal cavity, or nasopharynx. • Etiology includes: infection, trauma, allergic rhinitis, renal failure, nasal defects, hypertension, tumors, use of blood thinners, aspirin. • History:
Epistaxis • Classified by the location • Can be either anterior or posterior.
Anterior Epistaxis • Kiesselbach’s plexus most common. • Clinical Manifestations: • History • Unilateral bleeding • No sensation of post nasal drip • Blood is bright red
Anterior Epistaxis • Diagnostics • Hemoglobin/Hematocrit • CBC • Bleeding time
Anterior Epistaxis • Management: • ABC • Direct pressure. Pinch nostrils sit forward. • Cautery- chemical, electric, thermal. Silver nitrate sticks • Use of vasoconstrictors sprays. / anesthetic agents. • Anterior packing Merocel: compressed sponge. • Remove any clots visualized • Anterior epistaxis balloons.
Anterior Epistaxis • Complications of nasal packing: • Septal hematomas/abscess • Sinusitis • Pressure necrosis
Posterior Epistaxis • Usual source is the branches of the sphenopalatine artery. Bleeding occurs behind the posterior portion of the middle turbinate or posterior superior roof of the nasal cavity.
Posterior Epistaxis • Clinical Manifestations: • Nausea, hematemesis, anemia, hemoptysis or melena. • No visualized anterior source of bleeding • Post nasal drip of blood • Blood is dark red • Brisk arterial bleed
Posterior Epistaxis • Diagnostics: • Hemoglobin/ Hematocrit • History of bleeding disorder
Posterior Epistaxis • Management: • Attempt to locate the source • Vasoconstrictive/ anesthetic agents • Posterior nasal packing • Immediate otolaryngologist referral • Prophylactic antibiotics • Hospitalization and monitoring
Posterior Epistaxis • Indications for surgery/ embolization • Continued bleeding with packing • Required transfusion • Nasal anomaly precluding packing • Patient intolerance to packing
EpistaxisDifferential Diagnosis • Local irritation • Occupational exposure • Allergies • Malignancy due to systemic disease such as granulomatous disease(Wegener’s sarcoidosis) • Hereditary hemorrhagic telangiectasia(Osler-Weber-Rendu syndrome) • Bleeding disorders • hypertension
EpistaxisComplications • Sinusitis • Possibility of airway obstruction • Toxic shock syndrome • Septal hematoma or abscess • Septal perforation
Osler-Weber-Rendu syndrome • Disorder of blood vessels • Etiology: Genetic: • Clinical manifestations: telangiectases on the lips, tongue and nasal mucosa • Complications include hemorrhage
