thermal injury
Tissue damage from heat generated by electrosurgical devices during minimally invasive procedures.
Full Definition
Thermal injury in minimally invasive surgery refers to unintended tissue damage caused by heat from electrosurgical instruments such as monopolar cautery, bipolar devices, or ultrasonic scalpels. These injuries can occur through direct contact with activated instruments, capacitive coupling, or insulation failure. Thermal injuries may not be immediately apparent during surgery but can lead to delayed complications including bowel perforation, fistula formation, or tissue necrosis. Prevention strategies include proper instrument handling, insulation integrity checks, and appropriate power settings.
Usage
Usage note: Hyphenate when used as a compound modifier (thermal-injury prevention); distinguish from burns caused by external heat sources.
In Context
- "Post-operative fever prompted investigation for possible thermal injury to the bowel." — Complication assessment
- "The surgeon used lower power settings to minimize risk of thermal injury." — Operative technique note
