BACKGROUND
The hemostatic quality of the poly-N-acetyl glucosamine (p-GlcNAc) patch was compared with a fibrin sealant, fibrin bandage, and cellulose patch.
METHODS
A 2 x 2-cm capsular strip to a depth of 3 mm of the swine spleen was used as a source of bleeding. Splenic lacerations were created in
BACKGROUND
It has been shown that poly-N-acetyl glucosamine produces rapid hemostasis by stimulating erythrocyte aggregation. Endoscopic injection of this substance may be effective in the treatment of bleeding varices.
METHODS
In eight heparinized dogs with a bleeding esophageal varix greater than
OBJECTIVE
To compare the hemostatic capabilities of poly-Nacetylglucosamine (p-GlcNAc) with three currently available products: Actifoam, Surgicel, and Bolheal fibrin glue. This study was conducted in a controlled animal model, with monitoring of hematologic parameters over the course of the study.
BACKGROUND
The Rapid Deployment Hemostat (RDH) Bandage was developed for the rapid control of bleeding caused by trauma.
METHODS
An extremity wound involving skin, muscle, bone, and femoral arterial injury and a 1-cm vertical incision in the abdominal aorta in swine were studied to compare the RDH
BACKGROUND
Maintenance of functional vascular access is crucial for the delivery of hemodialysis. The SyvekPatch is a topical marine microalgal poly-N-acetyl glucosamine hemostat approved by the Food and Drug Administration for use in the local management of bleeding wounds, such as vascular site,
BACKGROUND
Vacuum-assisted closure (VAC) has become the preferred modality to treat many complex wounds but could be further improved by methods that minimize bleeding and facilitate wound epithelialization. Short fiber poly-N-acetyl glucosamine nanofibers (sNAG) are effective hemostatic agents that
BACKGROUND
The safety and efficacy of poly-N-acetyl glucosamine (p-GlcNAc) gels were compared with standard agents in three different dog studies to assess abdominal venous collaterals, bleeding esophageal varices, and bleeding gastric varices.
METHODS
Adult dogs with prehepatic portal hypertension
BACKGROUND
An advanced hemostatic dressing is needed to augment current methods for the control of life-threatening hemorrhage. A systematic approach to the study of dressings is described. We studied the effects of nine hemostatic dressings on blood loss using a model of severe venous hemorrhage
Polysaccharides are becoming increasingly developed as therapeutics and medical products, as the new field of Glycomics expands. Glycosaminoglycans that contain N-acetyl glucosamine constituents have been the focus of research leading to medical devices. A new hemostatic bandage, the Syvek Patch,
BACKGROUND
Topical hemostatic agents are frequently needed for control of intraoperative bleeding. Currently available topical products each have potential drawbacks, making a more effective topical hemostatic agent desirable. This study was performed to evaluate the effectiveness of a particular
Stress-induced hyperglycemia is necessary for maximal rates of survival after severe hemorrhage; however, the responsible mechanisms are not clear. One consequence of hyperglycemia is an increase in hexosamine biosynthesis, which leads to increases in levels of O-linked attachment of
BACKGROUND
The Rapid Deployment Hemostat (RDH) Bandage has been designed in collaboration with the Office of Naval Research for the treatment of bleeding because of extremity trauma. It is intended as both a battlefield and civilian severe trauma wound dressing. It consists of a specific formulation
The wound healing promoting effect of negative wound pressure therapies (NPWT) takes place at the wound interface. The use of bioactive substances at this site represents a major research area for the development of future NPWT therapies. To assess wound healing kinetics in pressure ulcers treated
BACKGROUND
It has been previously demonstrated that short-fiber poly-N-acetyl-glucosamine (sNAG) nanofibers specifically interact with platelets, are hemostatic, and stimulate diabetic wound healing by activating angiogenesis, cell proliferation, and reepithelialization. Platelets play a significant
OBJECTIVE
The purpose of this study was to evaluate the effect of chitosan on lingual hemostasis in rabbits whose coagulation pathway had been impaired by administration of intravenous heparin.
METHODS
Bleeding times were measured for bilateral (15 mm x 2 mm) tongue incisions in 10 New Zealand white
