Overview of Epistaxis Nose bleeds are very common. The majority are controlled by time and direct pressure. Anterior rhinoscopy will show a dilated septal mucosal vessel with an overlying sore or scab. Treatment consists of placing the mucosa at rest with a small cotton plug and vasolinated ointment for 35 days. Thereafter, the individual can apply the vasolinated ointment to their nose 2,3 or 4 times daily. For those on anticoagulants, the altered coagulation should be carefully checked and monitored. For those on aspirin as a general prophylaxis for arteriosclerosis, 80 mgs of aspirin is sufficient. Most use 300 mgs daily, as the adult aspirin tablets are easier to find and cheaper to purchase. If the vessel continues to bleed, it may benefit from cautery. Silver nitrate cautery will stop some, others will require electric cautery. Never cauterize both sides of the septum at the same time for this places the individual at risk for septal perforation. A few patients develop profuse epistaxis and these invariably come from medium sized arteries in the superior and posterior nasal cavities. These are only controlled by tamponading the bleeding vessel, accomplished by occluding the posterior choana and the anterior naris commonly called an anterior posterior pack. Assuming ENT referral is available, this is recommended. The otolaryngologist will typically vasoconstrict and anesthetize the nose and then endoscopically examine the nasal cavity. If the bleeding artery can be identified, it can be cauterized. If the bleeding is profuse and endoscopy is impossible, or if the septum is tortuous or the anatomy is such that the bleeding site cannot be seen, the otolaryngologist can place a more secure anterior posterior pack. Treatment alternatives are then threefold. The most conservative conventional approach is to hospitalize the patient and leave the packing in place for 35 days. The packing is then removed and most patients are successfully discharged. Three to five days of hospitalization is expensive. The anterior posterior pack is uncomfortable. A surgical alternative is to anesthetize the patient, examine the nose endoscopically, and cauterize the bleeding vessel. If the septum prevents this, a septoplasty is performed. If this is not successful then the internal maxillary artery and its contributing branches can be ligated in the sphenopalatine fossa behind the maxillary sinus. These are accessed through a standard Caldwell Luc procedure. Fifteen percent of nose bleeds arise from the ethmoid vessels, and in these cases an additional incision will be made between the nose and the eye and the anterior and posterior ethmoid arteries clipped. The third alternative is to perform an arteriogram and if the bleeding comes from the internal maxillary artery, embolize the artery. The anterior ethmoid arteries arise from the ophthalmic which arises from the internal carotid. These are not amenable to embolization. The disadvantages of arteriography and embolization are the expense and the small risk of a stroke. The skilled interventional radiologist-angiographer experienced in embolization can do this reasonably well and reasonably safely. For the most part angiography and embolization are reserved for very sick individuals who are significantly anticoagulated and for whom surgery is not a safe option. Nose picking is a contributing factor in epistaxis. Adults can usually be instructed to be more careful. Children pick their nose at night and this is best controlled by placing a glove or sock over their hand so that their fingers no longer fit inside their nose. Dry climates predispose to recurrent nose bleeds. Daily or twice daily application of vasolinated ointment provides substantial benefit. The polysporin antibiotics are not recommended as these predispose to topical sensitivity. Bacitracin containing ointments contain the necessary petroleum properties and are bacteriostatic. Other petroleum products such as A&D ointment, Aloe Vera ointment and even Vaseline probably work almost as well. There is a caveat for nose bleeds. While most are simple, straight forward problems, they are often the heralding sign of underlying coagulopathy. Hemophilia, von Willibrandt's disease, thrombocytopenia, all may have epistaxis as their initial symptom. |
