HF leakage current flows through metal parts
The patient must not have contact with electrically conductive ob-
jects. That includes metal parts of the operating table, for example.
HF current can be discharged through points of contact accidentally
(HF leakage current).
Risk of burns to the patient!
Position the patient on dry, antistatic drapes.
If the drapes can become wet during the surgery due to sweat,
blood, irrigation liquid, urine, etc., lay a waterproof plastic sheet
under the drapes.
The connecting cables (e.g., instrument cable, neutral electrode
cable) are touching each other or the patient.
Risk of burns to the patient and medical personnel!
Do not place the connecting cables on the patient.
Place the connecting cables separate from each other.
HF leakage current flows through monitoring electrodes
HF current can be discharged through points of contact between the
skin and monitoring electrodes accidentally (HF leakage current).
Risk of burns to the patient!
Position monitoring electrodes as far away as possible from the
procedural field (area where electrosurgical instruments are
used).
Do not use needle electrodes for monitoring during electrosur-
gery.
Where possible, use monitoring electrodes that contain devices to
limit high-frequency current.
HF leakage current flows through skin-to-skin points of contact
HF current can be discharged through skin-to-skin points of contact
accidentally (HF leakage current).
Risk of burns to the patient!
Prevent skin-to-skin points of contact. For example, lay dry gauze
between the patient's arms and body.
HF leakage current flows through the skin of medical personnel
Risk of burns to the patient and medical personnel!
Do not come in contact with the patient while the surgeon is using
an active electrosurgical instrument on the patient.
