Wounds

The term “wound” refers to an interruption in the continuity of tissues (skin or mucous membrane) as a result of damage.

Damage:

  • May be intended e.g. in case of surgical cutting
  • May be accidental, as a result of an injury
  • develops as a result of complex processes taking place in the course of many diseases

Wounds – types

Due to the depth of tissue damage, the following types of wounds are distinguished:

  1. a) superficial wounds: do not exceed the subcutaneous tissue
  • Abrasions and scratches – damage to the epidermis and superficial layers of dermis
  • Incisions – caused by a sharp object, slight tissue damage, rapid healing.
  • Contused wounds – caused by a blunt object, uneven wound edges, tissue bruising.
  • Chop wounds, crush wounds, lacerated wounds
  • Stab wounds – inflicted with a long sharp tool
  • Gunshot wounds – action of bullets or their parts.
  • Flap wounds – injury tangent to the skin surface, detachment of the skin from the substrate

Deep wounds

  1. b) deep wounds: Loss of continuity of the skin or mucous membrane, surrounding tissues, with full thickness loss of dermis.These type of wounds may also affect subcutaneous tissue and structures lying underneath it, i.e. tendons, muscles and bones.6

Factors worsening wound healing

It has been shown that the supply of L-arginine is an effective additional therapy for wound healing.7

Inside the wound or pressure ulcer, the amount of L-arginine decreases to an undetectable level, thus the external supply is essential for the wound to heal.
