What Is a Partial Thickness Debridement?

The skin is made up of the dermis and epidermis. The dermis, or bottom cells, migrate upward, creating the epidermis -- the top two to three skin layers. When injured, the movement of dermis to epidermis is hindered by proteins and intercellular material from the injury. At this point, debridement is needed.

Partial Thickness Debridement

• Partial thickness debridement occurs when damaged, dead or infected tissue needs to be removed from only the superficial (top) or periphery (outer edges) of the wounded area. The removal of dead tissue allows for replacement of the damaged cells by the underlying dermis.

Instruments Used

• Instruments for partial thickness debridement include tweezers, small scissors, hemostats, scalpel, cotton swabs, antibiotics, a bright light for vision of the wound and, on occasion, magnifying glasses. Depending on the type of the wound, it might require dressing ranging from wet to dry. The dressing collects liquid and infection inside the bandage from the wound and brings it to the top of the bandage so the dressing can be changed later.

Healing

• Healing occurs when the new cells are brought to the surface. Initially you will see a white crystallization around the periphery of the wound. The crystallization moves to the center of the wound until only new and healthy skin is left behind, leaving the wound healed.
