Burns Epithelial injury due to thermal, radioactive, chemical, or electrical agent. Generally the skin, but can involve respiratory and GI tract Local affect is not as serious as systemic effect (dehydration, shock, reduced circulation, urine production, bacterial infections) Four degrees of burns

1st Degree Pain Redness Swelling Tissue damage in the epidermis Sunburns are typically 1st degree burns

2nd Degree Pain Redness Swelling Blistering Epidermis damage and partially dermis Blood vessels and nerves are not affected

3rd Degree White or blackened, charred skin that may be numb Tissue is deep dermis to hypodermal layer Blood vessels and nerves destroyed Skin grafting is necessary to prevent infection, gangrene, and death

4th Degree Destroys all tissue Exposes muscle and bone

Wounds Skin deflects injuries and barrier against pathogens Process of wound healing depends on the extent and severity (Reading details the wound healing process)

Laceration Tissue tearing Blunt force Typically jagged edges, so scarring occurs

Abrasion Skin is rubbed off by rough surface “Road rash” Little to no scarring, depending on depth

Avulsion Skin catches on an object, while body part continues motion Tears the skin away from tissues below Skin may be torn completely off or hanging as a flap May be surgically re-attached or removed and replaced with skin graft Moderate scarring

Puncture Injury that is deeper than it is wide Surface may heal too fast, trapping infection inside Little scarring

Design Challenge Teams of 2-4 SHARE your table’s materials Remember: SUSTAINABILITY! Please do not waste materials. Choose to demonstrate one of the types of injuries: burn (first, second, or third degree), laceration, abrasion, avulsion, puncture Select a wound location. Examples are provided, but you can choose your own as long as it is not covered by clothing. Be sure to use anatomical terminology. If choosing the manus, you may create your wound on a glove. If the brachial, you may create your wound on the plastic wrap. Sketch the wound in the space provided. Describe the wound using anatomical terminology. Create your wound on ONE person in your team. Take a picture of your wound and text it to 352-874-5567 with names! Answer the analysis questions.

Time Remaining? Patient goes to a different group Have them diagnose the wound or burn Have them decide treatment plan Does your group agree? Explain. Write this on the back of your paper!
