ICD-10: T39.09

ICD-10 code T39.09 pertains to "Poisoning by, adverse effect of and underdosing of other salicylates." Salicylates, commonly known for their use in medications like aspirin, can lead to various clinical presentations when overdosed or when adverse effects occur. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this code is crucial for accurate diagnosis and treatment.

Clinical Presentation

The clinical presentation of salicylate poisoning can vary significantly based on the amount ingested, the patient's age, and their overall health status. Key aspects include:

• Acute Symptoms: Patients may present with symptoms shortly after ingestion, including nausea, vomiting, abdominal pain, and tinnitus (ringing in the ears) due to the irritative effects of salicylates on the gastrointestinal tract and central nervous system[1][2].
• Chronic Symptoms: In cases of chronic salicylate toxicity, symptoms may develop more gradually and include confusion, lethargy, and respiratory distress, often due to metabolic acidosis and respiratory compensation[3].

Signs and Symptoms

The signs and symptoms of salicylate poisoning can be categorized into mild, moderate, and severe manifestations:

Mild Symptoms

• Gastrointestinal Distress: Nausea, vomiting, and abdominal pain are common early signs[1].
• Tinnitus: A frequent early indicator of salicylate toxicity, often described as a ringing or buzzing in the ears[2].

Moderate Symptoms

• Respiratory Changes: Hyperventilation may occur as the body attempts to compensate for metabolic acidosis[3].
• Altered Mental Status: Patients may exhibit confusion, agitation, or lethargy as toxicity progresses[2].

Severe Symptoms

• Severe Metabolic Acidosis: This can lead to respiratory failure and shock if not addressed promptly[3].
• Cerebral Edema: In extreme cases, increased intracranial pressure can occur, leading to seizures or coma[1][2].
• Renal Failure: Acute kidney injury may develop due to dehydration and metabolic disturbances[3].

Patient Characteristics

Certain patient characteristics can influence the presentation and severity of salicylate poisoning:

• Age: Children are particularly vulnerable to salicylate toxicity due to their smaller body size and potential for accidental ingestion. Elderly patients may also be at higher risk due to polypharmacy and decreased renal function[1][2].
• Underlying Health Conditions: Patients with pre-existing conditions such as asthma, renal impairment, or liver disease may experience exacerbated symptoms and complications[3].
