Information to the hospital staff:

In waterjet cutting, water under extremely high pressure (up to 400 MPa) is used. A water jet beam which hits the body surface immediately penetrates the skin. This can happen even if protection equipment is used. An immediate spreading of water happens subcutaneously along the bundle. Corticalis (the surface) of the underlying skeleton parts can also be penetrated which can cause water to be pressed into the center of the bone. The hands are the most common localisation of injury. If the water used is contaminated by bacteria a spreading of bacteria’s in the total area of the wound may be a result.

Initially the symptoms appear relatively minor with a minimal wound and a slight swelling in the surrounding soft parts. Depending on the content of bacteria in the water and their virulence an infection can start in the tissue.

In a worst case scenario it is very strong and begins in a few hours. Severe pronounced damage of the tissue can follow.
 
The recommended treatment at manifested infection is immediate surgery in the form of splitting up. Also if the symptoms are minor at the first examination it is recommended that the damage is followed up because of the risk of infection. Prophylaxis of antibiotics should be considered.
