ELECTROCAUTERY

Surgical Diathermy or Electrocautery

Surgical diathermy or Electrocautery uses direct current whereas electrosurgery uses alternating current. Radiofrequency Generator:Generates high-frequency currents (100 K-Hz to 4 MHz) which induces ionic vibration but no movement.Ionic vibration generates intracellular heat but no muscle/nerve depolarization.Power settings are in Watts (amps x volts).Intracellular heat can cause:boiling + explosion (CUT), and/ordehydration…
