What are the risks for a 92-year-old man with hypertension experiencing a strong epistaxis (nose bleed)?

Risk Factors for Severe Epistaxis in a 92-Year-Old Man with Hypertension

A 92-year-old man with hypertension experiencing severe epistaxis faces multiple compounding risk factors: advanced age itself dramatically increases epistaxis severity and complications, hypertension is independently associated with more severe bleeding requiring emergency intervention, and this age group has significantly higher rates of posterior epistaxis which is more difficult to control and carries greater morbidity. 1, 2

Age-Related Risk Factors

• Advanced age (>85 years) increases the likelihood of emergency department visits for epistaxis by 3.24-fold compared to patients under 65 years 3
• Elderly patients are significantly more likely to experience posterior epistaxis (occurring in the lateral nasal wall or posterior septum), which is more severe, harder to control, and has higher hospitalization rates 3, 4
• Posterior epistaxis in elderly patients is frequently associated with atherosclerosis and conditions that decrease platelet and clotting function 4

Hypertension as a Risk Factor

The relationship between hypertension and epistaxis severity is well-established, though hypertension is not a direct cause of epistaxis itself. 1

• Patients with hypertension have a 47% increased risk of epistaxis requiring hospital visits (adjusted hazard ratio 1.47,95% CI 1.30-1.66) 2
• Hypertensive patients with epistaxis are 2.69 times more likely to require emergency department care and 4.58 times more likely to need posterior nasal packing compared to normotensive patients 2
• Elevated systolic blood pressure is independently associated with persistent epistaxis (odds ratio 1.03 per mmHg increase), with patients having persistent bleeding showing significantly higher systolic pressures (181 mmHg vs 157 mmHg) 5
• There is a trend toward association between duration of hypertension and left ventricular hypertrophy with epistaxis history, suggesting epistaxis may be a consequence of long-standing hypertension 6

Medication-Related Risk Factors

Anticoagulant and antiplatelet medications substantially increase epistaxis risk and severity. 1

• Approximately 15% of hospitalized epistaxis patients are on long-term anticoagulation 3
• Patients on warfarin require INR checking to evaluate therapeutic range, with supratherapeutic levels potentially requiring specialty consultation, medication discontinuation, or reversal agents for severe refractory bleeding 1
• Antiplatelet agents (aspirin, clopidogrel) can cause persistent epistaxis, as demonstrated in an 82-year-old case where bleeding only resolved after discontinuing both agents 1

Additional Risk Factors to Document

The American Academy of Otolaryngology-Head and Neck Surgery recommends documenting the following risk factors: 1

• Prior nasal or sinus surgery - can create vulnerable areas prone to bleeding 1
• Nasal cannula oxygen or CPAP use - causes mucosal dryness and trauma 1, 3
• Intranasal medications (particularly nasal corticosteroids) - increase epistaxis risk 2.74-fold 1
• Personal or family history of bleeding disorders 1
• Chronic kidney or liver disease - affect coagulation function 1, 3

Critical Management Considerations for This High-Risk Patient

Blood pressure management during acute epistaxis requires careful consideration in elderly patients. 1

• Routine acute blood pressure lowering is NOT recommended during active epistaxis, as excessive reduction can cause or worsen renal, cerebral, or coronary ischemia 1
• Blood pressure should be monitored, with decisions about control based on bleeding severity, inability to control bleeding, individual comorbidities, and risks of blood pressure reduction 1

Complications and Prognosis

Posterior epistaxis in elderly patients carries significant morbidity: 7

• 19.8% require surgical intervention after initial packing 7
• 21% develop acute sinusitis as a complication of packing 7
• 12.3% require blood transfusions 7
• 29.6% experience rebleeding, with 44% of rebleeding episodes occurring within 24 hours of admission 7
• Severe posterior epistaxis and pack removal within 48 hours are associated with increased rebleeding risk 7

Common Pitfalls to Avoid

• Do not aggressively lower blood pressure acutely - this can cause end-organ ischemia in elderly patients with chronic hypertension 1
• Do not assume anterior bleeding - elderly patients with hypertension are at high risk for posterior sources requiring endoscopic evaluation 3, 4
• Do not overlook anticoagulation status - check INR if on warfarin and consider reversal for severe refractory bleeding 1
• Do not remove packing prematurely - removal before 48 hours increases rebleeding risk 7
