Powder hemostats that offer an alternative solution to ensure haemostasias for wide-surface bleeding comes with numerous advantages compared to other hemostats. Powder hemostats provide a powder-like structure when applied to the bleeding tissue with the help of an applicator, provide bactericidal effect due to low pH properties against various microorganisms, penetrate to the source of bleeding and creates a matrix for thrombocyte adhesion and aggregation. (1, 2)

Powder hemostats manufactured from different raw materials such as oxidized regenerated cellulose with bactericidal properties are used in surgical procedures when ligation or other traditional control methods are impractical or ineffective to help managing the venous and small arterial bleeding. In this article, we will talk about the properties and usage areas of Reoxcel Powder absorbable powder hemostat manufactured from oxidized regenerated cellulose (ORC) (polyanhydride glucuronic acid) oxidation. (3,4)

Properties and Usage Areas of Reoxcel Powder Hemostats

Reoxcel Powder absorbable hemostats is in powder form in an applicator to easily apply on the bleeding areas and it is absorbed without tissue reaction in the implantation region when applied appropriately at minimum level to the wide-area bleeding region ensuring multi-dimensional compliance. The absorption rate of the Reoxcel Powder absorbable powder hemostat which provides bactericidal effect against 40 types of microorganisms depends on the tissue type, the amount of used powder hemostatic agent and blood saturation level. (1,2,4,5)

What Are The Usage Areas of Powder Hemostats?

Reoxcel Powder absorbable powder hemostat manufactured with ORC oxidation which works independent of the coagulation mechanisms of the body is designed to ensure to stop the parenchymatic organ bleeding and bleeding in recession areas during surgical operations for hemostats in the shortest time. Reoxcel Powder absorbable powder hemostat can be completely absorbed by the body between 7-14 days and can be used for stopping the bleeding when other hemostatic procedures are insufficient. (3,4)

Powder Hemostats Operation Mechanism

Reoxcel Powder absorbable powder hemostat forms a brownish or black gelatinous mass when it comes in contact with blood which aids clot formation. This gelatine-like mass acts as a physical structure for the blood platelet. The bleeding is stopped by blood platelet accumulation and platelet-fibrine plaque formation. (4,5)

Bactericidal Effect Against 40 Types of Microorganisms

Reoxcel Powder absorbable hemostat powder has been proven to have a bactericidal effect in vitro against 40 types of Gr (+) (gram positive) and Gr (-) (gram negative) microorganisms. The table below lists the microorganisms that Reoxcel Powder absorbable powder hemostatic agent provides antibacterial effect. (4, 5)

Hemostats also known as antihemorrhagic agents are hemostatic agents used on the bleeding region to stop the bleeding on a tissue or organ. The process to stop the bleeding is called haemostasias. The bleeding will stop on its own in individuals without any hemostasis mechanism disorders as inflammation stage by blood clothing. (1,13.14) When the body is insufficient to stop major or minor bleeding because of internal or external wounding due to external intervention, tearing, rupture, traumatic cuts, dental operations, surgical or spontaneous interventions, surgical intervention is performed and hemostatic agents must be used. (21) In this article, we will look into hemostats which are antihemorrhagic or hemostatic agents.

What Is Hemostasis?

Stopping the bleeding caused by tissue wounding, tearing or rupture due to trauma or surgical intervention is called hemostasis. When the tissue is cut and the bleeding starts, the defense mechanism will be activated as soon as the blood contacts with the air. The end of the cut vessels will contract at first. Then, there will be clothing at these ends and the coagulation will expand to block the vessel and stop the bleeding. The hemostasis state refers to blood coagulation and stopping the bleeding as a result of the relationship between natural-biologic or artificial-human intervention thrombocyte and coagulation factor. (1,7,11,13)

What Are The Usage Areas of Antihemorrhagic Hemostatic Agents?

In general, antihemorrhagic hemostatic agents are used for stopping both internal and external major or minor bleeding due to injuries, cuts, tearing, ruptures, traumatic cuts, dental operations, surgical or spontaneous interventions. (15)

What Are Hemostat (Antihemorrhagic Agent) Types?

The main hemostatic agents when we talk about hemostats are cellulosic or collagen-based agents. Also, there are antihemorrhagic agents with fibrine materials, synthetic adhesives or hemostatic powder or hemostatic matrix. Today, hemostatic agents produced from oxide cellulose are often preferred for minor bleeding. Cellulose hemostats produced in Boz Medical comply with “Oxidated Regenerated Cellulose” and “Oxidates Cellulose” standards of USP American Pharmacopeia. (1,3,15,21)

What Are Cellulose-Based Hemostatic?

This hemostatic agent which is the most preferred antihemorrhagic agent produced from oxidized cellulose was first developed as to act as a buffer for the bleeding tissue. This cellulose-based antihemorrhagic agent designed to induce the tissue for coagulation should only be used for the local management of minor bleeding. (1,3,4)

What Is Microfibril Collagen?

These are antihemorrhagic agent types developed in 1970 from bovine hide raw material to create hemostatic effect by applying on irregular surfaces in the bleeding region. This is a white, soft-looking, dry powder. (1,5)

What Is Anastomotic Adhesive?

Anastomotic adhesives that are used as hemostatic for surgical operations and trauma are divided into three as gelatin, thrombin and fibrinogen agents.

Hemostatic Agents With Bovine Gelatin and Human Thrombin

Collagen which is the building block protein type for the bovine or swine movement system is used for gelatin production. (16) Thrombin is coded by F2 gene in humans to trigger coagulation and created with thromboplastic effect from prothrombin in hemostasis. (7) This is locally applied to tissue surface for bleeding due to capillary damage. (6) The gelatin particles consisting of collagen and human derivative thrombin will expand when contacted with blood, absorb the blood 40 times more and can reach 200% times more that the initial size. These hemostatic agents are in sponge, solution or powder form.

Hemostatic Agents with Fibrinogen

Fibrinogen is an important protein produced by the body for the coagulation process. This is a protein type known as proto-coagulator and activates when any tissue in human body is damaged. Hemostatic agents with fibrinogen are combined with human derivative thrombin to turn into a stable fibrin. The existing thrombin levels around the wound region and fibrinogen levels determine the coagulation speed. (6,18)

What Is Synthetic Adhesive?

An adhesive type produced from bovine albumin and glutaraldehyde is applied to the bleeding wound for a flexible and practical sealing with this hemostasis method that is independent of the coagulation mechanism of the body. Glutaraldehyde molecules and bovine albumin molecules have covalent bound. (1)

What Is Micro Porous Polysaccharide Hemosphere?

Micro porous polysaccharide hemosphere (MPH) is plant-based and accelerates coagulation in contact. This is a fluid hemostatic powder designed for fast blood dehydration. After applying the powder on the bleeding surface, the osmotic effect of the dissolved materials inside the cell will expand the powder particles and increases the density of serum protein, thrombocyte or blood-platelet and other elements on the tissue. It creates the skeleton for fibrin coagulation as the hemostatic powder and tightened cells are coated. The hemostatic powder on the tissue is completely absorbed in 24-48 hours and the powder is enzymatically cleaned from the wound on the tissue or organ. (1,17)

What Are Chitin and Chitosan-Based Hemostatic Agents?

Chitin is one of the most important and second most common amino polysaccharide in the nature which is a type of carbohydrate used by arthropods such as crab and shrimp to dry the outer skeleton and by mushrooms to form the cellular wall. (8,10,19) While there are various chitin types, the most important one is chitosan. Chitosan was produced in 1894 by Hoppe-Seyler by processing chitin inside potassium hydroxide at 180°C (deacetylation) and chitosan was produced with decreased acetyl content. The data from the animals showed that hemostats containing chitosan acetate as an active ingredient decreased bleeding. Today, chitosan has an important place in the medical field and it is used as a raw material for antihemorrhagic agent hemostatic material production and animal and human band aid product as this material accelerates the wound healing by 30%.

What Is Zeolite Antihemorrhagic Agent?

Zeolite is a natural mineral in the nature and absorbs the water on the damaged tissue with exothermic reaction. Therefore, this material increases blood platelet density by breaking down the matured cells in coagulation factor and bone marrow to induce coagulation. (1,17)

Additionally, this material has FDA approval only for external bleeding. This is because 95% local temperature on tissue surfaces of animal models. As a result, there is need for more research since this material is dangerous for internal bleeding by considering the partial damage the material causes for external application. (1,20)

What Are Hemostats Similar to Ankaferd?

Ankaferd antihemorrhagic hemostatic agents are used as hemostats in Anatolia for centuries in alternative medicine field. These hemostats used for stopping the external bleeding are a plant-based mixtures used as a first-aid material rather than for medical operations. This is a hemostatic antihemorrhagic agent with two types which are spray and cream. (1,2,12)
