Microporous Polysaccharide Hemospheres Epistaxis

January 25, 2017 updated by: Oswaldo A Henriquez, Emory University

Use of Microporous Polysaccharide Hemospheres (MPH) in Management of Acute Epistaxis

The purpose of this study is to compare a new treatment for nosebleeds to the treatment that has been used for many years.

Detailed Description

Nosebleeds are a common condition which affect many Americans every day.The standard treatment in this hospital for nosebleeds that do not resolve with squeezing the nose or nasal spray is to place a nasal packing (aka nasal tampon) into the nose. This is an effective treatment in most cases, but patients may find it to be uncomfortable. The investigators will be comparing the standard nasal packing with a new type of powder which may also stop nosebleeds.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Microporous Polysaccharide Hemospheres (MPH)
Subjects with acute epistaxis will receive microporous polysaccharide hemospheres (Arista) powder. In the event that Arista fails to assist in resolving nosebleed in 15 minutes, subjects will be promptly escalated to the control group and will receive Merocel.
Device: Microporous Polysaccharide Hemospheres
Two grams of Arista powder will be placed into the nose followed by four minutes of pressure and a moustache dressing.
Other Names:
  • Arista
Device: Nasal Tampon
8 cm of Merocel dressing will be placed into one or both sides of your nose for the next three to five days and will then be removed by the physician.
Other Names:
  • Merocel
Active Comparator: Merocel (Control)
Subjects with acute epistaxis will receive standard-of-care treatment, nasal tampon (Merocel). In the event that Merocel fails to assist in resolving nosebleed in 15 minutes, subjects will be promptly escalated to the MPH group and will receive Arista powder.
Device: Microporous Polysaccharide Hemospheres
Two grams of Arista powder will be placed into the nose followed by four minutes of pressure and a moustache dressing.
Other Names:
  • Arista
Device: Nasal Tampon
8 cm of Merocel dressing will be placed into one or both sides of your nose for the next three to five days and will then be removed by the physician.
Other Names:
  • Merocel

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of subjects with resolution of bleed
Time Frame: 15 minutes (average time to resolve bleeding)
Resolution of bleeding is determined by cessation of blood flow anteriorly from the nares as well as posteriorly in the pharynx. This will be determined by the otolaryngology resident or attending managing the patient during the study.
15 minutes (average time to resolve bleeding)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time until resolution of bleeding
Time Frame: 15 minutes (average time to resolve bleeding)
Number of minutes it takes to resolve bleeding comparing the Arista powder group versus the Merocel tampon group.
15 minutes (average time to resolve bleeding)
