In salicylate poisoning the treatment recommended is:
**Core Concept**
Salicylate poisoning occurs when excessive amounts of aspirin or other salicylates are ingested, leading to a buildup of salicylate ions in the body. This condition can cause a range of symptoms, including tinnitus, hearing loss, and respiratory alkalosis.
**Why the Correct Answer is Right**
The treatment of choice for salicylate poisoning is alkaline diuresis. This involves administering fluids and bicarbonate to increase urine production and promote the excretion of salicylate ions from the body. The mechanism involves the kidneys' ability to secrete salicylate ions in exchange for sodium ions in the renal tubules, which is enhanced by the presence of bicarbonate.
**Why Each Wrong Option is Incorrect**
**Option A:** Alkaline diuresis is the treatment of choice for salicylate poisoning, whereas forced diuresis with water alone is not effective in promoting the excretion of salicylate ions.
**Option B:** Activated charcoal may be administered to prevent further absorption of salicylates from the gastrointestinal tract, but it does not effectively treat existing salicylate poisoning.
**Option C:** Hemodialysis may be necessary in severe cases of salicylate poisoning, particularly if the patient is showing signs of severe toxicity, but it is not the recommended initial treatment.
**Clinical Pearl / High-Yield Fact**
In patients with salicylate poisoning, a key clinical correlation to remember is that the treatment of choice, alkaline diuresis, should not be initiated until the patient is adequately hydrated and has a stable cardiovascular system.
**Correct Answer: C. Hemodialysis may be necessary in severe cases of salicylate poisoning, particularly if the patient is showing signs of severe toxicity, but it is not the recommended initial treatment.
