Electrosurgery Safety Checklist: 10 Must‑Do Steps Before Every Procedure
Electrosurgery saves lives every day, but a single missed setting can turn a clean cut into a burn disaster. That’s why I keep a printed checklist on my OR side table – it’s my “second pair of eyes” when the lights are bright and the stakes are high.
Why a Checklist Matters
In the OR we trust our hands, our training, and the machines we use. Yet even the best devices can misbehave if we forget a simple step. A checklist forces us to pause, verify, and protect the patient before the scalpel even touches skin. It also gives the whole team a shared language – no more “I thought you checked that” after the case is over.
1. Verify Patient Identity and Procedure
Before you even think about the electrosurgical unit (ESU), confirm the patient’s name, MRN, and the exact procedure. I still remember a junior resident who almost started a laparoscopic cholecystectomy on the wrong patient because the wristband was swapped. A quick “Name and DOB?” saved the day and reminded me why the first line of any safety list is always the patient.
2. Review the Electrosurgical Mode Required
Electrosurgery has three basic modes: cut, coag, and blend. Cut uses continuous high‑frequency current for a clean incision, coag uses intermittent bursts to stop bleeding, and blend mixes the two for a balanced effect. Knowing which mode you need prevents accidental burns or inadequate hemostasis. If you’re unsure, ask the device rep or check the manufacturer’s guide – it’s better to ask than to guess.
3. Check the Grounding Pad Placement
A grounding (or return) pad must be placed on a well‑vascularized, muscle‑rich area away from bony prominences. The pad should be flat, free of hair, and have good contact. I once saw a pad placed on a patient’s thigh with a small skin fold underneath; the resulting high resistance caused a spark that singed the drape. A quick visual and tactile check avoids that embarrassment.
4. Inspect Cables and Connectors
Frayed cables, loose connectors, or mismatched plugs can interrupt the circuit and cause unpredictable spikes. Pull gently on each cable, wiggle the connector, and make sure the “click” is firm. If anything feels loose, replace it. The ESU is a delicate instrument; treat it like a prized scalpel, not a disposable cord.
5. Set the Correct Power Level
Every tissue type has an optimal power range. Too low and you’ll waste time; too high and you risk thermal injury. Most modern ESUs have preset levels for common procedures – use them. If you must adjust manually, start low and increase incrementally. I keep a pocket card with typical wattage ranges for skin, fascia, and organ work; it’s a lifesaver during emergencies.
6. Confirm the “Active” Electrode Type
There are monopolar and bipolar electrodes. Monopolar requires a grounding pad and delivers current through the patient; bipolar has both active and return tips on the same instrument, limiting current spread. Using the wrong type can lead to unintended burns. Double‑check the tip label and make sure the device matches the planned technique.
7. Test the Circuit Before Incision
Most ESUs have a “test” button that sends a low‑energy pulse to verify continuity. Press it and watch the indicator light or hear the beep. If the test fails, abort the case and troubleshoot. I’ve saved a patient from a near‑miss by catching a faulty cable during this quick test.
8. Ensure Proper Smoke Evacuation
Electrosurgery produces surgical smoke that contains toxic chemicals and viral particles. A smoke evacuator with a high‑efficiency filter should be positioned within 2‑3 inches of the active tip. Not only does this protect the OR staff’s lungs, it also improves visibility. I like to turn the evacuator on a second before I fire the first cut – it’s a habit that feels almost ritualistic.
9. Review Patient‑Specific Contraindications
Some patients have implanted devices (pacemakers, neurostimulators) that can be affected by high‑frequency currents. Always check the chart for any “no electrosurgery” notes. If a device is present, consider using bipolar energy, a lower frequency, or a different hemostatic method. I once had to switch to a harmonic scalpel because the patient’s pacemaker was set to “sensitive” mode – a good reminder that technology is not one‑size‑fits‑all.
10. Communicate the Plan with the Team
Finally, announce the electrosurgery plan out loud: mode, power, electrode, and any special precautions. A simple “We’ll be using monopolar cut at 30 watts with the grounding pad on the right thigh” aligns everyone – surgeon, scrub tech, anesthesiologist, and circulating nurse. It also gives the team a chance to ask questions before the first incision.
A Quick Recap (for the busy surgeon)
- Patient ID – name, DOB, procedure
- Mode – cut, coag, blend
- Ground pad – flat, well‑vascularized, secure
- Cables – no frays, tight connections
- Power – start low, use presets
- Electrode – monopolar vs. bipolar, correct tip
- Test – run the circuit check
- Smoke – evacuator on, close to tip
- Contraindications – implants, special conditions
- Team brief – speak the plan aloud
When I first started using this checklist, I thought it was “extra work.” After a few months, it became second nature, and the OR ran smoother, quieter, and safer. The checklist isn’t a bureaucratic hurdle; it’s a simple habit that protects the patient, the staff, and your own peace of mind.
Stay sharp, stay safe, and keep those electrosurgical units humming the right way.
