3. Basic principles: Accidental (non surgical) wounds should be considered infected, therefore we should remove: - the causative agents - the devitalized tissues Accidental wound should be transformed to surgical one. PhasesManagement InspectionUnder sterile circumstances (hat, mask, gloves) Anamnesis  Elucidation of the circumstances of injury  Tetanus  Rabies Diagnostic procedures Exclusion of accompanying injury Examinations of the circulatory, sensory and motoric functions Exclusion of bone fractures (X-ray) Wound management The accidental wound care should be based on the depth of injury and the danger of infection with primary- or delayed wound closure (see next table). About wounds - in general

4. Types of wound closure Definite primary wound management (within 12 hrs)Immediate wound closure Always perform primary wound closure:  penetrating injury of the abdomen  chest  dura mater - Primary delayed suture (3-8 days) - Early secondary wound closure (> 14 days ) - Late secondary wound closure (4 - 6 weeks ) When primary wound closure is contradicted:  infectious signs  severely spoiled  foreign body  pouched, greatly bruised wounds  special injury forms of some professions (e.g. surgeons, butcher, veterinarian, pathologist, bacteriologist)  bite, shot, deep incised wound  hostility wound

5. Local anesthesia Excision Primary suture Drain Primary wound closure - debridement

7. Depending on the function: - adherent/taped bandages: (to fix covering bandages or for the approximation of edges of small wounds) - covering bandages: (to protect the wound and absorb secretion. Prevention from secondary infection and mechanical trauma) - pressing bandages: (for temporary handling of capillary and venous bleedings under 40- 60 mmHg.) - wedging bandage (used for temporary handling of capillary arterial and venous bleedings until surgical management. Should be relieved in every 2 hrs) - compressing bandages: (to prevent postoperative bleeding on the limbs, and for the prophylaxis of thrombosis and for the reduction of chronic lymph-edema. Always placed from distal to proximal - fixing/retention bandage (to immobilize the injured body part or to fix the reposition). TYPES OF BANDAGES

8. 1.Layer in direct contact with the wound (sterile, hypoallergenic, not irritating, non-sticking) - simple sheet (e.g. Mull sheet: good fluid absorbent, but easily sticks to the wound) - impregnated sheet (vazeline, paraffin: ie. “Jelonet”, non-sticking) (with saline which melts when gets into contact with body fluids i.e. Mesalt.) 2.Absorbent layer (to absorb and store blood and excretions) 3.Fixing layer to secure the bandage (adherent tapes i.e. Centerplast, Leukoplast or Mefix, Mepore; the latter two for bigger surfaces). Layers of bandages
