Decreased urine output after burns

Introduction Reduced urine volume after burns (generally refers to adult urine volume below 20 ml per hour): It is an important and early manifestation of burn shock. If kidney function is not seriously damaged, urinary oliguria can generally reflect tissue blood perfusion and severe shock. degree. The main cause of oliguria is insufficient blood volume and reduced renal blood flow. Of course, it is still associated with increased levels of anti-urinary hormones and aldosterone. If there is no urine, the systolic blood pressure is below 10.7 kPa. When there is oliguria, there are many other serious symptoms such as shock, severe dehydration, heart failure, acute glomerulonephritis, renal insufficiency and so on.

Cause

Insufficient blood volume and reduced renal blood flow. Of course, it is still associated with increased levels of anti-urinary hormones and aldosterone. When there is oliguria, there are many other serious symptoms. Common diseases include shock, severe dehydration, heart failure, renal artery embolism, renal tumor, acute glomerulonephritis, and renal insufficiency. If you find that you have less urine during the day and there are no other symptoms, you should consciously drink more water to increase the amount of urine. This will not only promote the discharge of metabolic waste in the body, but also help flush the urinary tract through the urine. Infection of the urinary system.

The diagnosis of burn shock can be made based on clinical manifestations. If conditions permit. The necessary laboratory tests such as plasma osmotic pressure, hematocrit, red blood cell count, hemoglobin count, hemoglobin, etc., are helpful for early diagnosis of burn shock and can also be used as a therapeutic reference.

Differential diagnosis

Pulse growth after burns: one of the symptoms of burn shock. The majority of burn shock is secondary shock, usually occurring in the first few hours or more than 10 hours after burn. It belongs to hypovolemic shock because of the large amount of plasma in the wound from the capillaries to the wound and tissue. The gap causes a reduction in effective circulating blood volume.

Thirst after burns: It is due to a large amount of fluid exudation of Jiangyang after severe burns, which reduces blood volume, resulting in insufficient circulating blood volume. The larger the burn area, the more severe the exudation and the more obvious the thirst, which is the clinical manifestation of the early occurrence of burn shock. The diagnosis of burn shock can be made based on clinical manifestations. If conditions permit. The necessary laboratory tests such as plasma osmotic pressure, hematocrit, red blood cell count, hemoglobin count, hemoglobin, etc., are helpful for early diagnosis of burn shock and can also be used as a therapeutic reference.
