During surgical procedures, the types of hemostasis listed below can be used to control bleeding while avoiding and reducing the risk of tissue destruction. Hemostasis can be achieved by chemical agent as well as mechanical or physical agents. Which hemostasis type used is determined based on the situation. [8]
Halsted's principles, also known as Tenets of Halsted, are the basic principles of surgical technique regarding tissue handling. [1] These key points were introduced in the late 19th century by William Stewart Halsted, co-founder of Johns Hopkins Hospital.

They vary based on their mechanism of action, composition, ease of application, adherence to tissue, immunogenicity and cost. These agents permit rapid hemostasis, better visualization of the surgical area, shorter operative times, decreased requirement for transfusions, decreased wound healing time and overall improvement in patient recovery time.
The test is started by adding appropriate reagents. The instrument measures and graphically displays the changes in elasticity at all stages of the developing and resolving clot. The typical test temperature is 37 °C, but different temperatures can be selected, e.g. for patients with hypothermia.
Hemostats. A hemostat (also called a hemostatic clamp; arterial forceps; and pean, after Jules-Émile Péan) is a tool used to control bleeding during surgery. [1] Similar in design to both pliers and scissors, it is used to clamp exposed blood vessels shut.
Intraoperative blood salvage (IOS), also known as cell salvage, is a specific type of autologous blood transfusion. Specifically IOS is a medical procedure involving recovering blood lost during surgery and re-infusing it into the patient.
The course covers the theoretical basis and practical skills required to manage critically ill surgical patients. It is managed by the Royal College of Surgeons of England. The 4th edition, which reduced the duration to 2 days, was released in February 2017.
