Welcome to Week 9 Seminar! Trauma Trauma Units The Golden Hour The Primary Survey Airway Breathing Circulation Primary Survey Secondary Survey What do you do? A is for Airway The first, and most important factor to be assessed. Is Time Important? Polytrauma Polytrauma Hospitals Open Trauma Abrasions Outer layers skin scraped away Deeper layers exposed Avulsions Portion or skin and underlying tissue torn away Puncture Wounds Sharp foreign object penetrates soft tissue Example, animal bites Lacerations Sharp object cuts the skin Open Trauma Potential Complications with open wounds? Practice Tetanus toxoid prophylaxis is important in any person who has sustained open trauma because: A. boosters are required throughout life. B. tetanus toxoid is a broad-spectrum antibiotic C. organisms that cause tetanus enter the body directly into the bloodstream through wounds. D. All of the above Thermal Injury Hyperthemia Heat Exhaustion Heat Stroke Hypothermia Heat Illness Heat Exhaustion - a state of collapse (fainting) due to hypotension brought on by: 1.Depletion of plasma volume (sweat loss) 2.Large dilation of skin blood vessels 3. Result is hypotension due to decreased cardiac output and total peripheral resistance Heat Illness Heat Stroke - complete breakdown of heat-regulating systems, which can cause large increases in core body temperature (T co ) Symptoms: - collapse - delerium - seizures - unconsciousness All of the symptoms are due to prolonged T co elevations. The usual cause is exposure to hot/humid conditions. Hypothermia Body temperature below 95F Signs and Symptoms Numbness Fatigue Disorientation Shallow breathing Frostbite Frozen tissues Usually found on: Toes Ears Fingers Treatment? Practice A. Shivering B. Disorientation C. Fatigue D. All of the above What Disease/Condition Am I?
