Generally, the diagnosis of burn shock can be made based on the clinical manifestations of acid burns. If conditions permit, necessary laboratory tests such as plasma osmolality, hematocrit, red blood cell count, hemoglobin count, hemoglobin, etc., can help in the early diagnosis of burn shock and can be used as a reference for treatment. The necessary laboratory tests can help in the early diagnosis of burn shock and the judgment of the progress of the disease. The laboratory changes of burns are mainly reflected in the following three aspects. Laboratory tests: 1. pituitary The trigger reaction of the adrenal glands, manifested as eosinophilia, lymphocytes and platelet reduction, increased blood catecholamine content. 2, hypovolemia Low blood flow and tissue hypoxia are reflected by blood concentration, increased red blood cell count, increased hemoglobin and hematocrit, decreased central venous pressure, metabolic acidosis, decreased arterial partial pressure of oxygen, normal or decreased partial pressure of carbon dioxide, normal or decreased pH of arterial blood, decreased carbon dioxide binding capacity of venous blood, decreased buffer base and residual base in blood, etc. Metabolism, manifested as blood glucose, blood non-protein nitrogen, increased blood potassium, low blood sodium, etc. 3. The reflection of visceral organ dysfunction varies depending on the surface of the visceral organ dysfunction.
