He made the predecessor to the modern hemostat and called it the Bec de Corbin (crow's beak) (see image below). With it he could clamp a bleeding vessel before securing it with a ligature . Bec de Corbin. The modern hemostat is credited to several persons, the foremost of which is Jules-Émile Péan.
What is a hemostat used for?
Hemostats have three functions in emergency wound care . Originally, hemostats were designed to clamp small blood vessels for hemorrhage control. Another use is to grasp and secure superficial fascia during undermining and débriding wounds. Finally, this instrument is an excellent tool for exposing, exploring, and visualizing the deeper areas of a wound. Two types of hemostats are commonly used in wound care. For general use, the standard hemostat is recommended. Finer work in small wounds is often best served by the 5-inch curved mosquito hemostat with fine serrated jaws.
What is hemostatic powder used for?
Hemostatic powders have been used to treat significant gastrointestinal bleeding from diffuse mucosal lesions and lesions such as tumors that are unresponsive to conventional therapy.
What are the devices used in colonoscopy?
Hemostatic and ablative devices used during colonoscopy include contact thermal devices (heater probe and multipolar electrocautery probes), noncontact thermal devices (ar gon plasma coagulator and laser), injection needles, and mechanical devices (band ligators, Endoclips, and detachable ligating loops) ( Figure 158-10; see also Figure 158-7 ). 71 Hemostatic monopolar or bipolar forceps are novel alternatives for the treatment of gastrointestinal bleeding. 72,73 Hemostatic principles for the control of lower gastrointestinal bleeding (LGIB) are the same as used for upper gastrointestinal bleeding, though with a tendency to use less coagulation energy in order to avoid bowel perforation. In general, epinephrine injection alone or in combination with thermal coagulation is commonly used for hemostasis of active bleeding, especially from postpolypectomy and diverticular hemorrhage ( Figure 158-11 ). Preferred methods of thermal coagulation are bipolar or multipolar (heater probe) because of their limited depth of coagulation and are used to treat visible vessels or after cessation of active bleeding from vascular lesions, postpolypectomy sites, or colonic diverticula. Argon plasma coagulation can be used for treating superficial vascular lesions, such as vascular ectasias and chronic radiation proctopathy, the latter with sustained responses in 83% to 100% of patients. 74
How does hemostatic system work?
The hemostatic system has evolved to play a critical role in maintaining a delicate balance between keeping the blood in the fluid state so that flow is uninterrupted at all times and responding to any disruption of the vascular continuity so that extravasation is rapidly arrested by the formation of a hemostatic plug. This delicate balance is altered by changes in blood flow, the vessel wall, and/or soluble and cellular constituents of blood leading to thrombus formation (thrombosis), as proposed by Virchow in the past century. Thrombosis of the coronary and cerebral arteries consequential to rupture of the underlying atherosclerotic plaque is the major cause of morbidity and mortality in developed countries. In the past 2 decades, there have been considerable advances in the characterization of vascular and hemostatic factors at the molecular level. These advances enhance our understanding of the mechanisms by which hemostatic and thrombotic plugs are formed. As a result, newer antithrombotic agents have been developed and several of these agents have been evaluated by clinical trials. This chapter attempts to summarize the recent advances in our understanding of the mechanism of action of the newer antithrombotic drugs and their potential advantage over existing agents.
What is the role of hemostatic factors in thrombosis?
The hemostatic system maintains a delicate balance between thrombus formation and clot lysis to prevent blood loss and maintain vascular patency. Activation of coagulation and platelets leads to thrombin generation, platelet deposition and fibrin formation, while naturally occurring anticoagulants limit thrombin generation and the fibrinolytic system is involved in clot remodeling and lysis. Perturbation of these processes gives rise to bleeding disorders or to thrombosis. The contribution of genetic factors to the pathogenesis of venous thrombosis is indicated by a strong family history in individuals with premature thrombosis and causal mutations in a variety of genes encoding hemostatic factors have been identified. The development of arterial thrombosis is more complex; however, an important role for thrombosis is supported by familial clustering and the identification of variants in candidate genes encoding hemostatic factors that are associated with arterial thrombosis. Genome-wide association studies (GWAS) have successfully identified novel genetic loci associated with a number of intermediate hemostatic phenotypes. However, although gene variants associated with cardiovascular disease have also been identified through GWAS approaches, associations of disease-associated SNPs with hemostatic intermediate phenotypes have not been consistently demonstrated to date.
What is the role of familial clustering in arterial thrombosis?
The development of arterial thrombosis is more complex; however, an important role for thrombosis is supported by familial clustering and the identification of variants in candidate genes encoding hemostatic factors that are associated with arterial thrombosis.

Current health care has an emphasis on outcomes.
What is flowable hemostat?
Flowable hemostats have a thick but flowable consistency and contain a bovine or porcine gelatin matrix. Topical thrombin may be added. They are helpful when application is needed into difficult-to-reach surfaces or in a wet field. The products can be used for all surgical procedures other than ophthalmic. Surgiflo (Johnson & Johnson) contains porcine gelatin and can be mixed with thrombin. 27 FloSeal (Baxter) contains bovine gelatin matrix and human pooled plasma thrombin. 28
What is the function of thrombin?
The active hemostats include topical (bovine) thrombin (Thrombin-JMI), topical (human) thrombin (Evithrom), and topical (recombinant) thrombin (Recothrom). These agents are indicated as an aid to hemostasis whenever ongoing oozing blood and minor bleeding from capillaries and small venules are accessible. The active agents stimulate activity in the coagulation cascade and promote the conversion of fibrinogen to fibrin ( FIGURE 1 ). 8
What is hemorrhagic IMC?
Hemorrhagic IMC is a diagnostic challenge. The clinical presentation may be quite variable and masked by other conditions such as anticoagulant or antiplatelet therapy, vitamin K or liver disease, disseminated intravascular coagulation, acidosis and hypothermia, and hemodilution due to blood loss. 17,18 The management of hemorrhagic IMC often requires a hematology consult. Supportive care with extended follow-up of laboratory tests can manage a patient in the absence of overt bleeding. For the bleeding patient, packed red blood cells, platelet transfusions and immunosuppressive therapy (corticosteroids, cyclosporine), chemotherapy (cyclophosphamide, vincristine), or epsilon aminocaproic acid may be required. 12,19-21

What is Arista starch?
Arista (Medafor) is a plant-derived polysaccharide starch that acts like a sieve to dehydrate blood. This polysaccharide sphere concentrates the solid components of blood to help the blood-clotting proteins. These spheres are composed of sugar, and not more than 50 g should be used in patients with diabetes to avoid glucose overload. Studies have shown this product to be efficacious in reducing capillary, venous, and arteriole bleeding that cannot be treated by other conventional means. However, specific safety data have not been demonstrated in neurologic, urologic, and ophthalmic surgeries, and the product is not recommended for use with bone adhesives. 1
