What treatment for salt overdose?

Answer 1

Hyperkalemia (too much potassium in the blood) is a medical emergency. It can induce EKG changes. Emergency aggressive therapy must be initiated.

One way to reduce the serum potassium levels is by driving potassium into the cells. This can be achieved by administering insulin + dextrose. Insulin is needed to move the potassium into the cells, but dextrose (sugar) is also given to avoid hypoglycemia (low blood sugar).

However, calcium gluconate IV is administered temporarily until the potassium is driven into the cells by the insulin. Calcium gluconate does not decrease the blood level of potassium. Instead, it antagonizes the effect of the potassium on the heart muscle.

Answer 2

Injestion of water to dilute the saline content, either orally, SQ or IV. Gastric lavage if there's a reasonable chance the salt has not left the GI tract. I note this question is categorized for "hair" as well as Health. I am not aware of any correlation between NACL overdose and hair conditions.
