  5. Friction burns • rubbing of the skin • outer layer • anti-inflammatory creams

  6. Thermal burns • flames • hot liquids • hot objects • gases

  7. Electrical burns • accidental electrical contact • depend on: • strength of electrical current • duration of contact • commoncauses : workplace injuries • rare causes: lightning

  8. Radiation burns • UV light • X-rays • sunlamps • radiation therapy

  10. Classification • First degree burn  superficial • Second degree burn  partial thickness • Third degree burn  full thickness • Fourth degree burn subcutaneous tissue, muscles, bones

  11. First-degree burns • epidermis • symptoms • redness • pain • dry skin • no blisters • no scars • example – mild sunburn

  14. Fourth-degree burns • epidermis, dermis and underlying tissue • symptoms • black skin • no sensation • example - flames

  15. Complications • infection • peripheral vascular resistance and hypovolemia • acute tubular necrosis • cardiac arrhythmias • cardiac arrest

  16. Treatment • Relieving pain NONSTEROIDAL-ANTI-INFLAMMATORY DRUGS • Preventing infection  antibiotics • Maintaining –body fluids electrolytes
