What is the main purpose of using a tourniquet during surgery?

The primary purpose of using a tourniquet during surgery is to temporarily restrict blood flow to a specific area to reduce bleeding. When a tourniquet is applied, it compresses the blood vessels in the limb or area being operated on, which minimizes blood loss and makes it easier for the surgical team to see the surgical field clearly. This is particularly vital in procedures where significant bleeding can complicate the operation or pose a risk to the patient's safety.

Using a tourniquet effectively allows surgeons to focus on the surgical technique and proceed with the procedure more efficiently. By controlling blood flow, it creates a bloodless field, reducing the risk of complications associated with excessive bleeding and improving overall outcomes for the patient.
