Case study: 3rd Degree Burns

Case study: 3rd Degree Burns

1. Integumentary (epithelial) system

   • Physiology: protects against environmental hazards, regulation of body temperature, provides sensory information
     • physical barrier
       • first line of defence
         • We are extremely succeptible to infection due to the loss of this initial barrier

   • Anatomy
     • Anatomy: skin, hair, sweat glands, nails
       • Cells
       • Glands
     • Epithelial cells
       • Stratified
         • Squamous
         • Cuboidal
         • Columnar
       • Simple
         • Squamous
         • Cuboidal
         • Columnar

2. Disruption of homeostasis related to third degree burns

   • Fluid loss
   • Dehydration
   • Electrolyte imbalances
   • Thermoregulatory issues
     • Heat
       • Vasodilation and sweating are the body's main defense against the heat
     • Cold
       • Vasoconstriction and shivering
         • Non-shivering thermogenesis, primarily in infants
         • Shivering thermogenesis, increases metabolic rate by 10x
   • Catecholamine mediated changes in cardiac physiology
