Clinical Symptoms of Aspirin Poisoning

Clinical Presentation of Poisoning

Identification of Symptoms

• A patient who presents with the following symptoms may be suspected of having ingested a harmful substance:
  • Rapid breathing: Indicates possible respiratory distress or compensation for metabolic acidosis.
  • Nausea and vomiting: Common non-specific symptoms of poisoning, can indicate gastrointestinal irritation or systemic effects.
  • Ringing in the ears (tinnitus): A symptom often associated with certain toxic substances, particularly salicylates like aspirin.
  • High fever: Can signify an infection, but in the context of poisoning, may indicate metabolic changes or direct effects of toxins on the body.

Substance Suspected

• Given the combination of symptoms above, the ingestion of a significant quantity of the following substances should be suspected:
  • a. Aspirin (Acetylsalicylic Acid):
  • Known to cause symptoms such as ringing in the ears (tinnitus), nausea, vomiting, and respiratory alkalosis followed by metabolic acidosis when ingested in large quantities.
  • b. Ibuprofen:
  • Typically causes gastrointestinal upset but is less likely to produce tinnitus and the combination of acute symptoms as described.
  • c. Cocaine:
  • May cause various neuropsychiatric symptoms but does not commonly present with the combination of symptoms listed (nausea, vomiting, high fever).
  • d. Tylenol (Acetaminophen):
  • Can lead to liver toxicity but does not typically present with rapid breathing or tinnitus as prominent symptoms.

Conclusion

• The symptoms described strongly suggest that the substance likely ingested is aspirin, particularly due to the presence of ringing in the ears and high fever alongside nausea and vomiting.
