Epistaxis

Nasal bleeding that does not stop with a topical vasoconstrictor and direct pressure applied by the patient (described below in the “Technique” section).


PROCEDURES



imagesCauterization


   imagesAnterior source bleeding that can be visualized


imagesAnterior Nasal Packing


   imagesAnterior source bleeding that cannot be visualized


   imagesCauterization fails


imagesPosterior Nasal Packing or Balloon Tamponade


   imagesAnterior source cannot be identified and


      imagesBleeding from both nares or


      imagesBlood draining into the posterior pharynx


   imagesAnterior packing of both nares fails to control bleeding


CONTRAINDICATIONS



imagesNone


RISKS



imagesNasal packing can cause pain or discomfort


imagesRisk of infection, septal damage, and ulceration


imagesRisk of balloon migration, airway obstruction, or aspiration with posterior packing


LANDMARKS



imagesThe choice of procedure depends on the source of bleeding. The source can be identified by direct visualization, or with use of a nasal speculum (described in more detail in the “Technique” section).


imagesNosebleeds are most commonly anterior (80% to 90%), originating from the Kiesselbach plexus in the septum


imagesMost posterior nosebleeds originate from branches of the sphenopalatine artery in the posterior nasal cavity or nasopharynx. A posterior source is likely when an anterior source cannot be identified, when bleeding is from both nares, or when blood is draining into the posterior pharynx.

TECHNIQUE



imagesPatient Preparation


   imagesAsk the patient to blow his or her nose, which decreases the effects of local fibrinolysis and removes clots (FIGURE 75.1)


   imagesAsk the patient to lean forward and apply continuous pressure to the alae of both nares for 10 to 20 minutes. If this stops bleeding, consider sending patient home with follow-up to ear, nose, and throat (ENT) specialist or Primary Medical Doctor (PMD).


imagesAnalgesia


   imagesApply a topical anesthetic and vasoconstrictor


      imagesSoak cotton or gauze in 2% lidocaine with or without topical epinephrine or 4% topical cocaine. Place in the nasal cavity for 15 to 20 minutes.


      imagesAlternatively, a topical anesthetic with a decongestant (2% lidocaine and 4% phenylephrine mixed 1:1) or oxymetazoline hydrochloride (Afrin) nasal spray may be used


   imagesBecause patients may be apprehensive and packing is uncomfortable, opiates or benzodiazepines may be given before the examination (strongly recommended in cases of posterior packing)


imagesVisualization


   imagesPosition the patient sitting upright, facing forward in the sniffing position


   imagesInsert a nasal speculum so that one blade moves superiorly and the other inferiorly and spread the nares vertically. Suction all remaining clots and blood. This permits visualization of most anterior sources.


imagesCauterization


   imagesIf an anterior source is visualized, cauterization should be attempted. To be effective, cautery should be performed after bleeding is controlled. Only cauterize one side of the septum at a time to prevent perforation or necrosis of the septum.


   imagesChemical cauterization can be performed using silver nitrate sticks. Apply the tip of a silver nitrate stick to the bleeding site until a white precipitate forms (usually a few seconds, rarely more than 10).


   imagesIf bleeding is vigorous, electrocauterization can be used. Apply the device to the bleeding site for up to 10 seconds or until a white precipitate forms.
