Thermal spread
Unintended extension of heat energy beyond the target tissue during electrosurgical procedures, potentially causing collateral damage.
Full Definition
The phenomenon where thermal energy from electrosurgical devices extends beyond the intended target tissue, potentially causing injury to adjacent structures. In laparoscopic surgery, thermal spread is a particular concern due to close proximity of vital organs and limited tactile feedback. Factors influencing thermal spread include power settings, electrode design, tissue characteristics, and duration of energy application. Understanding thermal spread is crucial for preventing complications such as bowel perforation, nerve injury, or vascular damage during laparoscopic procedures.
Usage
Usage note: Critical safety concept that should be emphasized in surgical education and documentation.
