Electrosurgery – FAQ

What is the difference between high-frequency surgery (HF surgery) and cautery?

In HF surgery, the heat (thermal effect) is produced by the flow of current in the tissue itself (endogenous). In cautery, an instrument such as a thermocautery device heats the tissue from the outside (exogenous).

Why does HF surgery not result in neuromuscular irritation?

In HF surgery, alternating currents with a frequency of over 200,000 Hz (200 kHz) are used. In this high frequency range, the flow direction changes so quickly between plus and minus that the current does not cause neuromuscular irritation.

In electrosurgery, which colour symbolises cutting and which symbolises coagulation?

On the handle and the foot pedal, the yellow switch activates the cutting current and the blue switch activates the coagulating current.
This colour code is internationally standardised.

What is the difference between monopolar and bipolar HF surgery?

In monopolar HF surgery, the current flows from the instrument's active electrode through the patient to the large neutral electrode and back to the generator. With bipolar HF surgery, two active electrodes are integrated into the instrument. Current only flows in the specific tissue region between the two electrodes. A neutral electrode is therefore not required.

What point is used as a reference for selecting the application site of the neutral electrode?

The level of the heart is used as a guide for selecting the application site. Depending on the surgical field, the neutral electrode is preferably placed on the nearest upper arm or thigh but not closer than 20 cm to the surgical site. The path of the current must not go through the heart!

Why should split neutral electrodes be used for electrosurgical devices with a contact-quality monitoring circuit?

With split neutral electrodes, the resistances between the two contact strips and the patient's skin are continuously measured. Advantage: Alarm notification with application stop when the neutral electrode detaches during surgery minimises risks.
