EPISTAXIS BY

1. EPISTAXISBY

2. Introduction • Epistaxis is a greek word meaning nose bleed. has been a part of the human experience from earliest times • Hippocrates commented that holding pressure on the nose helped to abate bleeding. Kiesselbach and Little(1879) were the first to identify the nasal septum’s anterior plexus as a source of nasal bleeding. • Pilz(1869) was the first to surgically treat epistaxis with arterial ligation

3. Incidence • Epistaxis, has been reported to occur in up to 60 percent of the general population. It has a bimodal distribution, with peaks at ages younger than 10 years and older than 50 years. • Affected persons usually do not seek medical attention, particularly if the bleeding is minor or self-limited. In rare cases, however, massive nasal bleeding can lead to death. • The incidence increases with advancing age, during the winter months, and is more common in males

4. Anatomy • The rich vascular supply of the nose originates from the ethmoidal branches of the internal carotid arteries and the facial and internal maxillary divisions of the external carotid arteries. Although nasal circulation is complex epistaxis usually is described as either anterior or posterior bleeding. This simple distinction provides a useful basis for management.

6. Common bleeding Sites • Kiesselbachs plexus Littles area • Woodruffs Area • Retrocolumellar vein • Middle turbinate

7. Local causes Epistaxis digitorum (nose picking) &Trauma Foreign bodies • Intranasal neoplasm or polyps • Irritants (e.g., cigarette smoke) • Medications (e.g., topical corticosteroids) • Rhinitis, Sinusitis acute and chronic • Septal deviation , Septal perforation • Adenoids Vascular malformation or telangiectasia

8. Systemic causes • Haemophilia • Hypertension • Leukemia • Liver disease (e.g., cirrhosis,Factor defeciency) • Medications e.g., aspirin, anticoagulants, nonsteroidal anti-inflammatory drugs • Platelet dysfunction & Thrombocytopenia • Others • Diffuse oozing, multiple bleeding sites, or recurrent bleeding may indicate a systemic process

9. Idiopathic • Vast majority of cases come under this category

10. Bleeding patterns • Septum littles area • Above the middle turb ethmoidal vessels • Below the middle turb sphenopalatine A • Posterior woodruffs area • Generalized bleeding disorder

11. Site and age relationship • Anterior 1/3 bleeds in adults Commonest from littles area Posterior 2/3 bleeds in old age At the juntion of floor and lateral wall

12. Examination • Every attempt should be made to locate the source of bleeding that does not respond to simple compression and nasal plugging. • The examination should be performed in a well-lighted room, with the patient seated and clothing protected by a sheet or gown. • The doctor should wear gloves and other appropriate protective equipment (e.g., surgical mask, safety glasses). • A headlamp /head mirror and a nasal speculum should be used for optimal visualization

13. Examination contd • Clots and foreign bodies in the anterior nasal cavity can be removed with a small suction tip, irrigation, forceps, and cotton-tipped applicators.

14. Initial Management • Application of direct pressure to the septal area and plugging of the affected cavity with gauze or cotton that has been soaked in a topical decongestant. • Direct pressure should be applied continuously for at least five minutes, and for up to 20 minutes. • Tilting the head forward prevents blood from pooling in the posterior pharynx, thereby avoiding nausea and airway obstruction. • Hemodynamic stability and airway patency

15. Management Principles • Although most patients with epistaxis can be treated as out patients, hospital admission and close observation should be considered for elderly and patients with posterior bleeding or coagulopathy. Admission also may be prudent for patients with complicating comorbid conditions such as IHD, severe hypertension or significant anemia

16. ANTERIOR EPISTAXIS • If a single anterior bleeding site is found, vasoconstriction should be attempted with topical application of oxymetazoline or phenylephrine solution. For bleeding that is likely to require more aggressive treatment, a local anesthetic, such as a • 4% Xylocaine solution, should be used. Adequate anesthesia should be obtained before treatment proceeds.

17. Cautrization • Larger vessels generally respond more readily to electrocautery. However, it must be performed cautiously to avoid excessive destruction of healthy surrounding tissues. • Use of electrocautery on both sides of the septum may increase the risk of septal perforation. • Some studies found no difference in efficacy or complication rate between chemical cautery (silver nitrate ) and electrocautery

18. Anterior nasal packing • anterior nasal cavity should be packed, from posterior to anterior, with ribbon gauze impregnated with petroleum jelly or polymyxin B-bacitracin zinc-neomycin . Nonadherent gauze impregnated with petroleum jelly and Bipp also works well .Bayonet forceps and a nasal speculum are used to approximate the layers of the gauze, which should extend as far back into the nose as possible. Each layer should be pressed down firmly before the next layer is inserted .Once the cavity has been packed as completely as possible, a gauze "drip pad” may be taped over the nostrils and changed periodically.

19. Anterior nasal packing

20. Complications of nasal packing • Procedures include septal hematomas and abscesses from traumatic packing, sinusitis, syncope during packing, and pressure necrosis secondary to excessively tight packing. • possibility of toxic shock syndrome with prolonged nasal packing

21. POSTERIOR EPISTAXIS • Much less common than anterior bleeding . Posterior packing may be accomplished by passing a catheter through one nostril (or both nostrils), through the nasopharynx, and out the mouth . A gauze pack then is secured to the end of the catheter and positioned in the posterior nasopharynx by pulling back on the catheter until the pack is seated in the posterior choana, sealing the posterior nasal passage and applying pressure to the site of the posterior bleeding. • It requires special training and usually is performed by an otolaryngologist

22. Post nasal packing

23. Foleys catheter • A Foley catheter (10 to 14 French) with a 30-mL balloon may be used. The catheter is inserted through the bleeding nostril and visualized in the oropharynx before inflation of the balloon. The balloon then is inflated with approximately 10 mL of saline, and the catheter is withdrawn gently through the nostril, pulling the balloon up and forward. The balloon should seat in the posterior nasal cavity and tamponade a posterior bleed. With traction maintained on the catheter, the anterior nasal cavity then is packed as previously described. Traction is maintained by placing an clamp on the catheter beyond the nostrils, which should be padded to prevent soft tissue damage. As with anterior epistaxis, topical antistaphylococcal antibiotic ointment may be used to prevent toxic shock syndrome. However, use of oral or intravenous antibiotics for posterior nasal packing is documented

24. PERSISTENT BLEEDING • Patients with anterior or posterior bleeding that continues despite packing or balloon procedures may require treatment by an otolaryngologist. Endoscopy may be used to locate the exact site of bleeding for direct cauterization. • Hot water irrigation, a technique described more than 100 years ago, has been reexamined recently. This technique has shown promise in reducing discomfort and length of hospitalization in patients with posterior epistaxis.

25. Danger signals in a severe nosebleed • Heavy bleeding. • Palpitation, shortness of breath and turning pale. • Swallowing large amounts of blood, which will cause you to vomit.

26. Indications for surgical intervention • have been widely debated, but usually include failure of medical treatment after 72 hours, • nasal anatomy that precludes local treatments, patient refusal of medical management, • initial hematocrit of <38% (males), • and the need for transfusion. • Many authors have argued that a posterior bleed that will necessitate a posterior pack is indication enough to pursue surgical treatment.

27. Surgical measures • Arterial ligation • maxillary artery • anterior ethmoidal artery • posterior ethmoidal artery • external carotid artery • Embolization • Septal surgery • lasers

28. How to avoid nosebleeds • Avoid damaging the nose and excessive nose-picking. • Seek medical treatment for any disease causing the nosebleeds. • Get a humidifier if you live in a dry climate or at high altitude.

29. summary • The medical community’s understanding of epistaxis has increased dramatically. Our treatment, though somewhat modified over the years, has continued to include techniques first noted several thousand years ago.

30. Summary • Epistaxis is the manifestation of many different disease processes. Its treatment is as varied as its etiologies. Treatment will be most effective when underlying medical problems are understood, nasal anatomy is appreciated, and the patient’s response to treatment and general medical status are taken into account. The otolaryngologist should be familiar with treatment options and be able to offer surgical intervention, if necessary.
