HemCon Bandages have undergone extensive clinical studies to test efficacy and effectiveness. Below is a collection of published, peer reviewed journal articles by publication date that show data from these studies. Most are comparisons with other competitive products; others are collections of anecdotal data of both, HemCon and competitive products.
: Efficacy data comparing HemCon vs. Gauze in 2.7 mm arterial punch in inguinal femoral arteries. Pressure to injury 3 minutes. Dressings have to hold hemostasis for 30 minutes, if failed, second attempt.
HemCon® Bandage provided superior hemostasis to gauze.

Treatment of Dialysis Access Puncture Wound Bleeding with Chitosan Dressings.
Summary: Bleeding in hemodialysis patients. Safety and efficacy comparison between HemCon® Bandage and conventional gauze. Compared time to hemostasis and compression strap usage. Hemostasis analyzed at 2 and 4 minutes after application. Hemostasis - 2 min – HB 30%, Gauze 38%, 4 min – HB 86%, Gauze 72%. Compression strap usage was reduced by 50% with the HB.

Biomaterials
Use of chitosan bandage to prevent fatal infections developing from highly contaminated wounds in mice.
Summary: Ability to rapidly kill bacteria in vitro and in mouse models of infected wounds was tested. HemCon was more adhesive to the wound and conformed well to the injury compared to algianate. The data suggests that chitosan acetate rapidly kills bacteria in the wound before systemic invasion can take place, thus due to its chemical structure the HemCon® Bandage is antimicrobial and is superior to alginate bandage and silver sulfadiazine that may both encourage bacterial growth in the short term.
