First Year Fellows Endoscopy Course (July 30-31)

Video Transcription

Video Summary

In this video, the speaker discusses the topic of electrocautery and its use in endoscopy procedures. The speaker emphasizes the importance of understanding the basic terms and principles of electrosurgery, including current, circuit, voltage, resistance, and impedance. They explain how the electrosurgical generator produces a high frequency alternating current to achieve a heating or cautery effect in the tissue. The speaker also discusses the differences between cutting and coagulation currents, as well as the differences between monopolar and bipolar circuits. They describe the concept of current density and how it can be manipulated to achieve different thermal effects. The speaker provides examples of different applications and settings for electrosurgical generators, such as polypectomy, sphincterotomy, and argon plasma coagulation (APC). They also discuss considerations for grounding pads and the potential risks associated with pacemakers and hair interfering with the current. The video concludes with the speaker emphasizing the importance of knowing and understanding the equipment and its settings for safe and effective use in procedures.
