There have been reports of salicylate toxicity and in rare instances death from sports creams that contain methyl salicylate also known of oil of wintergreen. Salicylates are contained in many prescription and non-prescription products, from acetylsalicylic acid (aspirin), to methyl salicylate (oil of wintergreen) which is. Salicylate poisoning, also known as aspirin poisoning, is the acute or chronic poisoning with a salicylate such as aspirin. The classic symptoms are ringing in the Symptoms: Ringing in the ears, nausea, abdo.

Potassium and sodium bicarbonate are excreted in the urine.
This phase may last as long as 12 hours. Characterized by methyl salicylate poisoning aciduria in the presence of continued respiratory alkalosis occurs when sufficient potassium has been lost from the kidneys.
How should the results be interpreted?
The appropriate tests to order will vary based upon the actual presenting symptoms, but commonly may include: A salicylate level methyl salicylate poisoning be ordered when the diagnosis is methyl salicylate poisoning. The salicylate level should be followed serially, as the half-life can vary with exposure amounts.
At therapeutic doses, the half-life is generally between 3 and 12 hours, however this may increase up to 30 hours at toxic doses. The Done nomogram has not been shown to be as useful for salicylate toxicity as other nomograms for other ingestions.
Salicylate poisoning - Wikipedia
A basic metabolic panel and arterial blood gas can be useful in defining the patient's acid-base status and assessing for respiratory alkalosis and metabolic acidosis which can be seen in salicylate toxicity. In patients with intentional or unintentional overdoses, it methyl salicylate poisoning be useful to rule out common coingestants with a urine drug screen, acetaminophen level, ethanol level, and levels for methyl salicylate poisoning other medications that the patient takes on a regular basis or has access to.
Measuring serum osmoles to evaluate the osmolar gap can be useful in screening for other ingestants, particularly in the case of a metabolic acidosis with increased anion methyl salicylate poisoning.
Salicylate toxicity may lead to a low uric acid level, though it is not necessary to order this routinely.
An electrocardiogram is useful in general screening of patients with acute overdoses to look for signs suggestive of specific toxidromes. A complete blood count CBC and coagulation studies are useful to rule out hemolysis methyl salicylate poisoning can occur with salicylate toxicity.
methyl salicylate poisoning Patients with glucosephosphate dehydrogenase G6PD deficiency are particularly at risk for this. Only the non-ionized form can penetrate the cell membrane and therefore when the systemic pH falls and more salicylate is in the form of salicylic acid, there is a greater distribution into the cells.
Methyl salicylate poisoning is very important clinically since salicylate causes its major toxicity once it is intracellular. The metabolism and excretion of salicylic acid is also concentration dependent. The enzymatic metabolism of salicylic acid is saturable and at high levels, most of the removal is then due to excretion of salicylic acid in the urine.
Methyl salicylate poisoning excretion of salicylate is pH dependent as well.
Alkalinization of the urine increases the ionized form of salicylate which is then unable to diffuse out of the urine back into the tubular cell. Clinical and laboratory findings in salicylate intoxication Figure 2 lists the most methyl salicylate poisoning findings in salicylate intoxication. The symptoms of salicylate intoxication differ according to the age of the patient and whether the intoxication is acute or chronic.
In chronic intoxication and in the elderly, methyl salicylate poisoning will occur at lower levels. Clinical effects of salicylate intoxication.

The common symptoms in all settings are nausea, vomiting, tachypnea, tinnitus, stupor, coma, and convulsions. In severe intoxication, patients can methyl salicylate poisoning kidney and respiratory failure, cardiovascular collapse and coma. Tests that may be done include:
