What is important to keep in mind when performing electrocautery?

• A. Place a grounding pad on the patient's thigh or ground the patient
• B. Disinfect only after procedure
• C. Ignore grounding; it's optional
• D. Only use under minor anesthesia

Answer: (A)

Grounding a patient is essential when using monopolar electrocautery because the current must have a return path to complete the circuit. The grounding pad acts as a large, safe sink for the electrical energy, spreading it over a wide area to keep current density low and prevent thermal injury at the pad site or along the tissue path. The best practice is to place a well-adhered, clean, dry grounding pad on a large, well-vascularized area such as the thigh, away from the operative field, and to ensure good contact (no wrinkles, no moisture, no scar tissue or inflamed skin under the pad). Check the pad connection and cable before energizing the unit. If a suitable site cannot be found or if there are concerns about skin integrity, consider using bipolar electrocautery, which does not require a grounding pad. Disinfection should occur before the procedure, and the requirement for grounding is not dependent on anesthesia level.
