How are nosebleeds controlled by cauterization

Attempting a Novel Hemostatic Chitosan Sealant in the Treatment of Complicated Epistaxis

detailed description

Epistaxis is a common reason for emergency room visits and referrals to the ENT. Epistaxis management methods include nasal wrapping, chemical or electrical cautery, and arterial ligation or embolization.

There are numerous nasal wrap products on the market that are used to help or stop preventing nosebleeds. The ideal nasal pack should be effective in controlling bleeding. have antimicrobial properties and are well tolerated. There is currently no perfect nose pack, but some are closer to ideal than others. Nasal packs can be classified as non-absorbable and absorbable nasal packs.

Recently a new hemostatic product was launched and used in military wound dressings, the ChitoFlex®. ChitoFlex® consists of chitosan, a naturally occurring, biocompatible polysaccharide. Because chitosan has a positive charge, red blood is drawn to cells that have a negative charge. The red blood cells seal the wound, are pulled into the bandage and form a very tight, cohesive seal. The ChitoFlex® dressing has been demonstrated by AATCC Test Method 100-2004, Evaluation of Antibacterial Surfaces (America Association of Textile Chemists and Colorists Technical Handbook) as an antibacterial barrier in laboratory tests with a variety of Gram-positive and Gram-negative bacterial organisms.
