Burn Victim Case Study – BIO 168 Chief Complaint: 7-year-old girl admitted for severe second- and third-degree burns following her rescue from a burning house. History: Helen Hogan, a 7-year-old white female, was transported by ambulance to the emergency room after being rescued from her burning house. She was asleep at night when a spark from the family fireplace started a fire, leaving her trapped in her bedroom. By the time the fire rescue squad arrived, she had suffered severe burns and excessive smoke inhalation. In the emergency room, Helen was unconscious. She had second-degree burns over 5% of her body and third-degree burns over 15% of her body -- both covering her thoracic and abdominal regions and her right elbow. Her vital signs were quite unstable: blood pressure = 55 / 35; heart rate = 210 beats / min.; and respiratory rate = 40 breaths / min. She was quickly deteriorating from circulatory failure. Two IVs were inserted and fluids were administered through each. Her vital signs stabilized and she was transported to the pediatric intensive care unit (ICU). Helen regained consciousness the following morning, surprisingly complaining of only minor pain over her trunk. Following debridement of her burns and application of a broad-spectrum, topical antibiotic, a plastic epidermal graft was applied over the burned areas. Despite treatment with a broad-spectrum antibiotic, she developed a systemic staphylococcal infection, necessitating a switch to a different antibiotic. Helen began a long, slow recovery. Her position in bed had to be changed every 2 hours to prevent the formation of decubitus ulcers (i.e. bedsores). She lost 9 pounds over the next 3 weeks, despite nasogastric tube feeding of 5000 calories ("Kcals") per day. After 9 weeks, sheets of cultured epidermal cells were grafted to her regenerating dermal layer. By the 15th week of her hospitalization, her epidermal graft was complete, and she was back on solid foods, her antibiotics were discontinued, and she was discharged from the hospital with a rehabilitation plan for both physical and occupational therapy at home, as well as twice-weekly visits by a nurse.

Questions: Research the following questions about Helen’s case fully using lecture notes, your textbook, and any other sources to help you. Answer in full, complete sentences using proper terminology.

1.Briefly describe the three major layers that make up healthy skin and the connective tissue that holds it on. What is found in each layer and what purpose does each layer serve?

2.Briefly describe the extent of damage seen in first-degree, second-degree, and third-degree burns. How are they different?

3.Why was Helen (the patient) relatively pain-free when she woke up? Would she have been pain-free if she had suffered first-degree burns rather than third-degree burns?

4.Explain why Helen’s blood pressure was so low and her heart rate so high upon arrival at the emergency room.

5.Why was it important to immediately administer intravenous fluids to Helen?

6.What is a “broad-spectrum” antibiotic, and why did Helen need one so quickly?
