Summary

Nosebleeds (epistaxis) are a frequent cause of emergency department visits, reportedly inciting 1 in 200 visits. They are most common in those less than ten and older than seventy, often occurring in the winter months secondary to dry indoor heating. Epistaxis is associated with elevated blood pressures, but it is controversial whether hypertension is actual a contributing cause.

In non-life-threatening epistaxis, the first step in management is commonly the application of a topical vasoconstrictive medication. In many cases this will lead to cessation of the bleeding or facilitate the exam in those that continue to bleed. Frequently used medications include phenylephrine, oxymetazoline, and lidocaine with epinephrine.

Classic teaching has been to avoid the use of these medications in patients with elevated blood pressures due to concerns of inducing hypertensive crisis. Strict avoidance of topical vasoconstrictors in this patient group with epistaxis severely limits the treatment options for a many patients given the association between the two conditions.

Though universally taught, the actual effect of these agents on blood pressure remains unquantified. Studies investigating the prevention of nose bleeding during nasotracheal intubations suggest that the effect might be minor with little variation between agents.

Clinical question:

What is the effect of commonly used intranasal vasoconstrictors on blood pressure in volunteers without a history of hypertension.

Conditions

Interventions

DRUG

Oxymetazoline 0.05%

sterile gauze soaked in 5 milliliters (mL) of Oxymetazoline 0.05% into one nostril and placement of a nasal clamp. The nasal clamp and medication will be removed after 15 minutes.

DRUG

Phenylephrine 0.25%

sterile gauze soaked in 5 milliliters (mL) of Phenylephrine 0.25% into one nostril and placement of a nasal clamp. The nasal clamp and medication will be removed after 15 minutes.

DRUG

Lidocaine 1% plus epinephrine 1:100,000

sterile gauze soaked in 5 milliliters (mL) of Lidocaine 1% plus epinephrine 1:100,000 into one nostril and placement of a nasal clamp. The nasal clamp and medication will be removed after 15 minutes.

DRUG

Bacteriostatic 0.9% NaCL

sterile gauze soaked in 5 milliliters (mL) of Bacteriostatic 0.9% NaCL into one nostril and placement of a nasal clamp. The nasal clamp and medication will be removed after 15 minutes.
