surrounding body tissue. Currents trasferred in this way in nearby tissue can cause irreversible damage. the movement of
electrically charged ions in capacitively coupled tissue can cause currents that can heat tissue sufficiently to produce burns.
Several measures are used during electrosurgical operations to limit and minimize the risks of patient injury:
-
a better and more complete training for the medical staff;
-
visual examination of the surgical instrumentation (active electrode, laparoscope);
-
use of disposable electrodes (but the thinner insulation doesn’t reduce the risk of breakdown or capacitive coupling);
-
prohibiting the use of hybrid (plastic-metal) cannulas;
-
adopting tbipolar electrosurgery (not-versatile, but safer, because the necrosis happen only if there is a long and
continuous application of the current).
In the HF electrosurgery burns are a real hazard that can be minimized by the knowledge of the causes and especially if the
surgeon is prepared against these.
