Study Notes

Electrode Adhesive Pad

Minimum Size: 100mm²
Minimum Diameter: 1.2 cm

Electrosurgery: Patient Return Electrode

Avoid Placing on Metal Implants: Could divert current, causing excessive heat
Integrity Check: Ensure package is intact before use. Do not use if damaged.
Safety Belt: Do not place belt over electrode or cord.
Secure Connection: Ensure a secure return electrode to generator connection. A faulty connection could create an alternative current pathway, posing a danger.
Documentation: Maintain records.

Bipolar Electrosurgery

Current Flow: From generator to forceps with active tip and inactive tip. Returns to generator through inactive tip.
Does not flow through the body, unlike monopolar electrosurgery.
Safer for: Presence of implantable device like pacemakers or defibrillators.

Electrosurgery: Generalized Safety Factors

Restrictions: Avoid use in mouth, trachea, around head, or pleural cavity due to high oxygen concentration, creating fire risk.
Electrode Placement: ECG electrodes should be placed away from the surgical site to prevent burns.
Jewelry Removal: Remove rings and other jewelry to prevent burns from diverted current.

Electrosurgery: Electrical Burns

Greatest Hazard: Electrical burns are the primary risk associated with electrosurgery.
Deep Burns: Deeper and more extensive than flame burns.
Tissue Damage: Can cause widespread necrosis and deep thrombosis.
Debridement and Grafting: May be required to manage the burns.

Electrosurgery: Additional Safety Measures

Follow Manufacturer Instructions: Adhere to operating and maintenance protocols in the manual.
Malfunction Handling: Label malfunctioning Electrosurgical Units (ESUs) as non-functional and send them for service.
Smoke Evacuation: Protect patients and personnel from inhaling smoke generated during electrosurgery. Suction can help.
Inspect Instruments: Inspect insulated instruments for breaks, as current leaks can cause burn risks.

Microsurgery

Magnification: Procedure done under magnification, providing enhanced visual acuity of small structures.
Specialized Techniques: Requires specific instrumentation and training.
Vessel Sealing: Small vessels seal as tissue is divided.

Active Electrode

Sterile Component: Directs current flow to the surgical site.
Conductor Cord: Attached to the generator.
Cord Management: Passed off the field by the scrub person and attached to the generator by the circulating nurse.
Sterile Cord: Do Not Secure with Metal Instruments.
Handpiece Storage: Keep the handpiece and active tip in a holder.
Char Removal: Avoid scraping char with a scalpel, as it can cause debris discharge.
Minimizing Damage: Use the active electrode to minimize damage to adjacent tissue.
Disposable Components: Active electrode handpiece and cord are disposable. If reusing, inspect thoroughly.

Patient Return Electrode: Additional Safety Measures

Electrode Placement: Close to the active electrode site, reducing current flow through the body.
Electrode Location: Place on a large muscle mass after patient positioning.
Surface Considerations: Avoid placing on hair or scar tissue, as it acts as an insulator.

Monopolar Electrosurgery

Current Flow: From generator to active electrode, through the patient to the return electrode, and back to the generator.
Safety Feature: Generator grounds the current. A break in the circuit activates an alarm.
Power Setting: Surgeon determines current and power settings, which the circulating nurse adjusts.

Monopolar Electrosurgery: Patient Return Electrode

Current Return: Current returns to the generator through an inactive return electrode attached to the patient.

Electrosurgical Unit (ESU) Components

Generator: Produces electric current
Foot Pedal: Controls the current flow
Cord: Connects components
Active Electrode: Directs current to the site
Inactive Dispersive Return Electrode: Returns current to the generator

Electrosurgery: Principles

Tissue Cutting & Coagulation: Electrical current used for both.
Coagulation Effects: Extensive burning can cause necrosis.
Wound Healing: Burning can devitalize tissue, hindering healing and increasing infection risk.
Skin Incision: Not typically used for skin incision.
Other Applications: Useful for fat, fascia, muscle, internal organs, and vessels.
Muscle & Nerve Stimulation: Current passes through tissue without stimulating muscles or nerves.

Electrosurgical Unit (ESU) Generator

Current Output: Produces three forms of current:
- Coagulating Current: Intense heat to seal vessels.
- Cutting Current: Continuous high-energy output for tissue separation.
- Blended Current: Combination of coagulating and cutting currents, delivered in modified cycles.
