First Year Fellows Endoscopy Course (July 26-27)

7-Electrocautery_2024

Pdf Summary

Electrocautery is a crucial tool in endoscopy but also potentially the most dangerous due to its high frequency alternating current. The therapeutic basis of electrosurgery lies in producing heat at a cellular level, achieved by passing current through tissues. Different effects like cutting and coagulation can be achieved by varying voltage and current density. Understanding resistance and impedance in tissues is vital for effective use. The document emphasizes the importance of grounding pads and proper equipment setup to prevent harm to patients, outlining rules for safety. The text also discusses techniques like snare closure and bipolar vs. monopolar approaches in electrosurgery. Factors like pad placement, hair presence, and minimizing circuit length are critical for safe use. Specific considerations for patients with pacemakers or ICDs are highlighted, emphasizing the need for specialized consultation and equipment. The document also covers Argon Plasma Coagulation (APC) including its advantages, settings, and applications in various conditions. Physicians are reminded of their responsibility to understand electrical principles, equipment setup, and to prioritize patient safety during electrosurgical procedures. It stresses the importance of personal knowledge in managing and operating electrocautery devices effectively and safely.
