Calcium poisoning should be more accurately described as hypercalcemia, the cause of hypercalcemia should be clarified, and the treatment needs to be based on the cause of the disease to take appropriate measures to deal with the treatment of measures to increase urinary calcium excretion, inhibit bone resorption, dialysis treatment and treatment of the primary disease and so on. 1. Increase urinary calcium excretion: diuretics such as furosemide can be used to inhibit calcium reabsorption and increase calcium excretion. 2. Inhibit bone resorption: Calcitonin can inhibit bone resorption and increase urinary calcium excretion. 3. Dialysis: it can effectively emergency calcium poisoning but should not be used in patients with renal insufficiency. 4. Treatment of primary diseases: causes of hypercalcemia such as acute and chronic renal failure, primary hyperparathyroidism, malignant tumors. Effective therapeutic measures should be taken for the primary disease. Calcium poisoning may lead to cardiac arrhythmia, which should be consulted in hospitals in time, and appropriate treatment should be chosen under the guidance of professional doctors.
