Susan, age 42, has been burned over 30% of her body, including face, neck, arms, and chest, from a chemical explosion at work. ?
Susan is becoming dehydrated. Her B/P is 90/46, pulse 112, and respirations 32. Her urinary output for the past 24 hours is 100 mL. She is in burn shock. Describe the pathology that has resulted in these symptoms.
The loss of the skin surface leads to enormous losses of body fluids, electrolytes, and proteins. A protective mechanism in the body shifts the water from other tissues to the site of the burn, to compensate for the fluid loss. Unfortunately, this further reduces the blood volume and cellular fluids, which in turn lowers blood pressure and other vital signs and decreases urinary output. Additionally, the heart can no longer supply enough blood to perfuse the vital organs, thus the decreased urine output. ?
