In the context of energy use for hemostasis, bipolar energy is associated with which advantage?

• A. Less lateral thermal spread
• B. Increased energy requirement
• C. Cannot be used in wet fields
• D. Causes more collateral damage

Answer: (A)

Bipolar energy confines the current to the tissue between the two tips of the instrument, so heating is localized to a small area. This produces coagulation with much less spread of heat to surrounding tissue, reducing the risk of collateral injury to nearby structures. Because the energy path is short and self-contained, bipolar devices work well in tight spaces and even in wet fields. The other statements aren’t true: you don’t inherently need more energy with bipolar, and the device is not limited to dry fields; it also doesn’t cause more collateral damage.
