NOVAPAK is a sponge-like material made from materials found in shellfish. It is commonly used after nasal surgery or in nasal bleeding, as it promotes healing, decreases bleeding, and has antibacterial properties. Although NOVOPAK does not contain proteins or compounds known to be responsible for allergic reactions in people with a known allergy to shellfish, out of an abundance of caution, the manufacturer (Medtronic) has recommended avoidance in those with known shellfish allergy. There have been no reported allergic reactions in patients with shellfish allergy who were given chitosan bandages in emergencies (e.g. military applications). The study aims to investigate the safety of its use in patients with known shellfish allergy to improve healthcare quality and patient care support.
