These include both direct beam hazards such as tissue burns, eye damage, endotracheal tube fire, drape fire, and explosion of gases, or non-beam hazards (those that are secondary to the actual beam interaction) such as laser generated airborne contaminants (surgical plume), electrical damage, toxic dyes, and system ...

Can laser damage organs?

Internal Organs: Although rare, there is a minimal risk of damage to internal organs. This can occur if the laser fiber is not precisely controlled.

How does laser affect human health?

Laser light stimulates the cells that control the inflammatory process. The effect is seen in the form of decreased swelling, decreased redness and decreased tenderness. 2. Endorphins are released through stimulation of the nerve cells, which, like the laser light, influences inflammation.
