Nosebleeds

Introduction

Nose bleeds are common, but there are a great number of reasons for a nose bleed to occur, from the innocent dry mucous membrane to a serious intranasal tumor.

Fortunately most nose bleeds are only a nuisance, but occasionally life threatening blood loss can result from them, so each nose bleed should be viewed with caution and a physician should find out the cause in the particular patient. Here are a few of the common causes of nose bleeds (compiled from text of Ref. 4, p. 1747).

Symptoms

Most nose bleeds stop spontaneously with pressure after some time. However, when the patient has a blood coagulation problem, high blood pressure or a ruptured blood vessel of a nasopharyngeal angiofibroma profuse bleeding can occur, which is considered a medical emergency.

Common causes of nose bleeds

Medical condition: Comments:
infections of sinuses, rhinitis, cold viral, bacterial, fungal infections leading to inflammation
allergic rhinitis swelling and itching causing picking of nose
dry air in heating season dryness leads to breakdown of mucous membrane and bleeding
juvenile nasopharyngeal angiofibroma common in adolescent males
blood thinning hereditary coagulopathies; coumadin, ASA or heparin.
patients with high blood pressure arteries are more rigid in these patients leading to more profuse bleeding

Treatment

In an emergency the physician may have to stop an acute bleed through a procedure called tamponade where packing is applied into the affected nostril.

There are probes that can be inserted and inflated. Also, an ENT surgeon could stop a nose bleed by cauterizing the bleeding blood vessel (the larger blood vessels are located higher up, thanks to www.moondragon.org for the image) in the anesthetized patient. The underlying condition (see table) has to be addressed by appropriate therapy. With repeat nose bleeds the patient should be referred to an ENT specialist to rule out any more serious condition (like cancer). If the bleed is due to prominent dilated superficial veins in the mucous membranes of the nasal cavity, this can be remedied by cauterization of these under a local anesthetic.
