Use of Two Electrosurgical Devices on One Patient
CAUTION
Danger of burns from leakage currents to other medical devices!
When using two electrosurgical devices on one patient, there is danger of burns on
unintentional body areas of the patient caused by high-frequency leakage currents. Two
electrosurgical devices should be used on one patient only if medical requirements necessitate
this.
The following rules are to be observed in the concomitant operation of two electrosurgical
devices:
•
Only electrosurgical units with type CF application parts by KLS Martin may be used.
•
Each unit to be operated in monopolar application requires a neutral electrode separately
attached to the patient. It is mandatory to comply with the instructions for proper
application of the neutral electrode.
•
Exclusively bipolar application of a unit obviates the need for application of the neutral
electrode for this unit.
•
The expected current paths from each active electrode to the corresponding neutral
electrode must not overlap or intersect. To this end, always place each neutral electrode
in the immediate vicinity of the operation field.
•
The total power of the simultaneously applied currents must not exceed 400 W.
5.6
Work on Patients with Pacemakers or Other Implants
If patients have metallic implants, the RF current paths must, as a general rule, not lead
through these implants. This must be considered when applying the active and neutral
electrode
•
The neutral electrode must not be applied over endoprostheses.
In patients with active implants such as pacemakers or implanted electrodes, the application of
the electrosurgical unit poses a risk. Application could result in irreparable damage to the
active implant or impairment of its function. The following guidelines are to be observed.
•
Patients must be monitored using suitable technology.
•
A defibrillator as well as an external pacemaker should be kept ready for use.
•
The selected power output for the electrosurgical unit should be as low as possible.
•
Do not use the active electrode of the electrosurgical unit closer than 15 cm to the implant
or its electrodes.
•
Wherever possible, use bipolar technology.
•
The rules of application such as application of the neutral electrode must be carefully
followed.
