Question: 1 / 400

What is the purpose of a tourniquet in surgical procedures?

To reduce pain

To control bleeding

The primary purpose of a tourniquet in surgical procedures is to control bleeding. When applied correctly, a tourniquet occludes blood flow to a specific area of the body, allowing surgeons to work in a dry and blood-free field. This is particularly beneficial during procedures on the extremities, where excessive bleeding can obscure the surgical site and complicate the operation.

By maintaining better visibility and control during surgery, the tourniquet helps to minimize the risk of blood loss, which can lead to complications for the patient. Additionally, controlling bleeding allows for quicker surgical intervention and enhances the overall efficiency of the surgical team.
