Thermal injury secondary to laparoscopic fiber-optic cables

Abstract

This study demonstrates that the temperature at the tip of the optical light cord can induce extensive damage. The by-product of light, heat, can produce immediate superficial tissue necrosis that can extend into the subcutaneous fat even when the optical tip is not in direct contact with the skin. In addition, our study shows the variation in temperature that exists between light sources and bulb status. Overall, surgeons must realize and respect the potential complications associated with optical technology.

Principles and Safety Measures of Electrosurgery in Laparoscopy

“…In a study conducted by Hindle et al, 39 it was found that the maximum temperature at the optical cable was between 119.5° C and 268.6° C. They also found that when surgical drapes were exposed to the tip of the light source, the time to char was 3 seconds to 6 seconds, and significant injury was recorded with the optical cable 3mm from the skin. Hindle et al concluded that the temperature at the tip of the optical light cord can induce extreme damage and can produce immediate superficial tissue necrosis that can extend into the subcutaneous fat even when the optical tip is not in direct contact with the skin.…”

“…Alternative site burns occur when the patient's skin is in contact with metal or other conductive materials and the electric currents return to the ground or the electrosurgical unit through this site. 39 …”

Electrosurgery: what do young surgeons need to know?

“…It may also occur if a conductor comes into contact with patient skin, creating an alternate route for current flow, bypassing the dispersive pad. Another commonly overlooked potential hazard is burns caused by fibreoptic light cables placed too close to skin or surgical drapes, which can result in burns in a matter of seconds …”

Anaesthetic consideration for robotic nipple sparing mastectomy

“…Thermal injury of flap due to fibre-optic light and heated fumes from electrocautery[4] is prevented by intermittent evacuation of CO 2 , smoke and cooling of the flap with wet gauze. Variable heat conductance in the body tissue (lower conductance in adipose tissue as compared to muscle and skin) further protects against thermal injury.…”
