Proper patient preparation is essential prior to an electrosurgical procedure. Since a current will be flowing from the electrosurgical generator unit through the patient, the patient must be properly grounded to avoid electrical shock. If a metal surgical table is used, it must first be covered with a rubber mat and then covered with two surgical towels. The grounding plate may then be placed on top of the surgical towels. Never place a grounding plate directly on a metal table as electric shock would occur. Next, the grounding plate must be positioned under the patient so that 85%-95% of the grounding plate is in contact with the patient. Then, a conductive gel is placed on the grounding plate to ensure good contact between the patient and the grounding plate.
Patient positioning is critical during electrosurgical procedures. Alternate site burns may be caused by the current seeking an alternate route to the return electrode. This can occur if a patient has two body parts touching, such as crossed legs or a leg touching the chest. Therefore, the patient should be placed on the surgery table in such a manner that avoids any skin-to-skin contact points. Gauze may be placed between areas of potential contact to lessen the chance of accidental contact.
It is important to note that all patient jewelry that could conduct electricity should be removed prior to the electrosurgical procedure.
When preparing the surgical site, non-flammable disinfecting agents should be used. If flammable disinfectants must be used, they should be allowed to evaporate prior to using the electrosurgical generator unit.
