Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study is a prospective clinical trial to investigate the efficacy of a chitosan-coated nasal packing (ChitoFlex® used in conjunction with the HemCon Nasal Plug) in the management of difficult spontaneous epistaxis and to evaluate its healing effect on nasal mucosa.
The introduction of products that enhances hemostasis can have clinical advantages when associated with traditional nasal packing. These advantages include a better hemostatic control and the reduction of nasal packing duration. Furthermore, this study will help determine if there are any non-desirable effects that chitosan may have on the nasal cavity, such as the production of fibrosis and foreign body reaction.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
There are numerous nasal packing products available in the market, and are used to stop or prevent nasal bleeding. The ideal nasal pack should be efficient in controlling bleeding, have antimicrobial properties and be well tolerated. Currently, there is no perfect nasal pack, but some are closer to ideal than others. Nasal packs can be classified into non-absorbable and absorbable nasal packs.
Recently, a new hemostatic product has been introduced in the market, and used as a military wound bandages, the ChitoFlex®. ChitoFlex® is made of chitosan, a naturally occurring, bio-compatible polysaccharide. Because chitosan has a positive charge, it attracts red blood cells, which have a negative charge. The red blood cells create a seal over the wound as they are drawn into the bandage, forming a very tight, coherent seal. The ChitoFlex® -dressing has been demonstrated by AATCC Test Method 100-2004, Evaluation of Antibacterial Finishes (Technical Manual of the America Association of Textile Chemists and Colorists) as an antibacterial barrier in laboratory testing with a variety of gram-positive and gram-negative bacterial organisms.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Epistaxis Group
Subjects presenting with epistaxis that have not been controlled by traditional nasal packing, or that recurred immediately upon removal of the nasal packing will be included in this study. Subject will be evaluated during the packing period to determine the effect of hemostasis. Chitosan coated packing will be removed after 48 hours. Subjects' nasal cavities will be examined endoscopically to evaluate bleeding control, morphological changes induced by the chitosan coated packing.
One week after the removal of the packing, the patients will be endoscopically examined to assess the healing of the packed area, to monitor control of bleeding, and observe any potential delayed reaction to the packing material.
