BASICS OF ELECTROSURGERY AMT ELECTROSURGERY INTEGRATING SAFETY AND PERFORMANCE BASICS OF ELECTROSURGERY

Basics of Electricity

Electrosurgial Principles Current follows pathway of least resistance Current always seeks to complete the circuit As Resistance within the circuit increases, current flow decreases

Neromuscular Stimulation

Tissue Effects: Cutting Desiccation Fulguration Soft Coagulation Bipolar Argon Plasma Coagulation

Cutting Continuous high-frequency current Blended Current Cause quick, clean cutting Minimal Thermal Artifact Blended Current Combination of cutting and coagulation waveform characteristics Moderate hemostasis

Desiccation (Forced Coag) Contact Coagulation Slow drying out of tissue Varying degrees of thermal artifact Causes eschar to form

Fulguration (Spray Coag) Non contact High Voltage Electrical current arcs from electrode to tissue Superficial

Soft Coagulation Contact Coagulation Low Voltage Continuous waveform Non Sticking non charring Reproducible

Bipolar Contact coagulation Low voltage Safer than monopolar Non charring

Argon Plasma Coagulation Non contact Non Charring Superficial
