Surgical Anatomy and Laparoscopy Flashcards
1
Q
Estimated rate of serious complication at time of laparoscopy?
A
1%
2
Q
Types of electro surgical injury?
A
Insulation failure Direct coupling Capacitance coupling Direct thermal injury Thermal spread
3
Q
Insulation failure
A
Leaking of current through micro fractures in insulation of monopolar instrument
- avoid reusable monopolar instruments
4
Q
Direct coupling
A
Inadvertent contact of two non-insulated instruments
5
Q
Capacitance coupling
A
Two conductors separates by a non-conducting medium and stay current jumps from instrument to conductors
- eg. Hybrid ports
6
Q
Direct thermal injury
A
Inadvertent activation of electrosurgical instrument
7
Q
Thermal spread
A
Injury to adjacent structures
- different instruments have varying degrees of thermal spread
