What is the purpose of using a tourniquet in surgery?

Using a tourniquet during surgery primarily serves the purpose of temporarily restricting blood flow to a specific area. This is crucial for several reasons. By occluding blood vessels, the surgeon minimizes blood loss, which allows for better visibility of the surgical site and a cleaner field for the procedure. This is especially important in surgeries involving limbs or areas with significant vascular supply.

When blood flow is restricted, it reduces the risk of hemorrhage during the operation, which can complicate the procedure and increase recovery time. The tourniquet creates a controlled environment that aids in precise surgical maneuvers. Once the surgery is completed or the area has been sufficiently treated, the tourniquet is released, allowing normal blood flow to resume, which assists in healing post-operation.

This technique is particularly valuable in orthopedic surgeries, vascular procedures, and other scenarios where blood control is necessary for successful outcomes.
