Which of the following is NOT an hemostatic agent?

Oxytocin
Thrombin
Oxidized cellulose
Bone wax

The correct answer is: Oxytocin

Oxytocin is a hormone primarily involved in regulating various physiological functions, particularly childbirth and lactation. It is not classified as a hemostatic agent because it does not directly promote hemostasis or control bleeding during surgical procedures. In contrast, the other options presented are recognized hemostatic agents. Thrombin, for example, plays a crucial role in the coagulation cascade and is often used to enhance the clotting process. Oxidized cellulose acts as a topical hemostatic agent by providing a matrix for clot formation and also helps promote local tissue granulation. Bone wax is used in orthopedic surgery to control bleeding from bone surfaces by providing a physical barrier to blood flow. These materials actively contribute to the mechanisms of hemostasis, contrasting with oxytocin’s primary function in the body. Thus, the identification of oxytocin as not being a hemostatic agent is based on its lack of action in promoting clot formation or preventing hemorrhage.
