A surgical assistant might need to use a tourniquet particularly in situations requiring significant blood loss control. This scenario often arises in procedures where access to a vascular area is necessary or when the surgical field needs to be as blood-free as possible to ensure visibility and precision.

Using a tourniquet effectively constricts blood flow to the area being operated on, which minimizes bleeding and allows the surgeon to work without excessive blood interfering with the procedure. This is especially critical in orthopedic surgeries, such as limb amputations or joint replacements, where large blood vessels can be involved, and significant blood loss can occur if bleeding isn't managed effectively.

In contrast, while minor skin procedures may not typically require a tourniquet, cases of low blood pressure would generally lead to caution, as applying a tourniquet could exacerbate the patient’s condition. Additionally, tourniquets are not limited to elective surgeries; they can be applied in emergency situations as well when necessary to control life-threatening hemorrhage.
