Aspirin (Acetylsalicylic Acid [ASA])
- Clinical Manifestations
- Acute poisoning (early symptoms)
- Nausea
- Hyperventilation
- Vomiting
- Tinnitus
- Diaphoresis
- Acute poisoning (later symptoms):
- Hyperactivity
- Fever
- Confusion
- Seizures
- Renal failure
- Respiratory failure
- Chronic poisoning
- Same as above but subtle onset and nonspecific symptoms (often mistaken for viral illness)
- Bleeding tendencies
- Comments
- It may be caused by acute ingestion (severe toxicity occurs with 300 to 500 mg/kg).
- It may be caused by chronic ingestion (i.e., more than 100 mg/kg/day for 2 or more days) and can be more serious than acute ingestion.
- Time to peak serum salicylate level can vary with enteric aspirin or the presence of concretions (bezoars).
- Treatment
- Hospitalization is required for severe toxicity.
- Activated charcoal is given as soon as possible (unless contraindicated by altered mental status). If bowel sounds are present, may be repeated every 4 hours until charcoal appears in the stool.
- Lavage will not remove concretions of ASA.
- Sodium bicarbonate (intravenous) is used to correct metabolic acidosis, and urinary alkalinization may be effective in enhancing elimination; hypokalemia may interfere with achieving urinary alkalinization.
- Be aware of the risk for fluid overload and pulmonary edema.
- Use external cooling for hyperpyrexia.
- Administer anticonvulsants if seizures are present.
- Provide oxygen and ventilation for respiratory depression.
- Administer vitamin K for bleeding.
- In severe cases, hemodialysis (not peritoneal dialysis) is used.
