How should the dispersive electrode be placed during surgery?

The correct approach is to place the dispersive electrode as close to the operative site as possible. This positioning is essential because it ensures efficient electrical current flow through the patient's body during electrosurgery. When the dispersive electrode is positioned nearer to the surgical area, it helps minimize the risk of electrical burns and reduces the chances of current flowing through unintended pathways, which can lead to tissue damage.

By placing the dispersive electrode near the operative site, the current returns effectively to the generator, providing better control and safety during the procedure. This placement helps to optimize the effectiveness of the surgical instruments and contributes to a safer surgical environment for the patient. Additionally, it allows for effective grounding, which is crucial for patient safety.

Other options, such as placing the electrode far from the operative site or in a corner of the operating room, would not provide the same level of safety and efficacy. Positioning it on the patient's back is also ill-advised, as it is generally too far from the surgical area, potentially increasing the risk of complications. Thus, the correct positioning principle emphasizes proximity to ensure optimal current flow and patient safety.
