What can lead to unseen thermal burns during endoscopic procedures?

• A. Improper storage of instruments
• B. Insulation defects in instruments
• C. Excessive cleaning of tools
• D. Inadequate surgical lighting

Answer: (B)

Unseen thermal burns during endoscopic procedures can indeed result from insulation defects in instruments. During these procedures, various instruments are often used that may generate heat, such as those that utilize electrical energy. If the insulation on these instruments is compromised, it may allow heat to escape, potentially leading to burns. These burns could occur without any visible signs if the affected tissue is not directly exposed to the heat source, resulting in risks to patient safety.

In contrast, while improper storage of instruments, excessive cleaning of tools, and inadequate surgical lighting are relevant considerations in surgical practices, they do not directly lead to the specific issue of unseen thermal burns. Improper storage may lead to instrument damage or contamination, excessive cleaning may compromise the integrity of tools, and inadequate lighting can hinder visibility but does not cause thermal injuries through insulation failure.
