ICD-10: T46.1X2

ICD-10 code T46.1X2 specifically refers to "Poisoning by calcium-channel blockers, intentional self-harm." This classification falls under the broader category of poisoning and adverse effects related to drugs and chemicals, particularly focusing on cases where the poisoning is self-inflicted.

Clinical Description

Definition

Calcium-channel blockers (CCBs) are a class of medications primarily used to treat hypertension, angina, and certain arrhythmias. They work by inhibiting the influx of calcium ions into cardiac and smooth muscle cells, leading to vasodilation and decreased heart rate. Common examples include amlodipine, diltiazem, and verapamil. Poisoning from these substances can occur when an individual intentionally ingests a toxic dose, often as a means of self-harm.

Symptoms of Poisoning

The clinical presentation of calcium-channel blocker poisoning can vary based on the amount ingested and the specific drug involved. Symptoms may include:

• Cardiovascular Effects: Hypotension (low blood pressure), bradycardia (slow heart rate), and potential heart block.
• Neurological Symptoms: Dizziness, confusion, or loss of consciousness.
• Gastrointestinal Distress: Nausea, vomiting, and abdominal pain.
• Respiratory Issues: Difficulty breathing or respiratory depression in severe cases.

Diagnosis

Diagnosis of poisoning by calcium-channel blockers involves a thorough clinical assessment, including:

• Patient History: Understanding the circumstances surrounding the ingestion, including intent and timing.
• Physical Examination: Assessing vital signs and neurological status.
• Laboratory Tests: Blood tests may be conducted to measure drug levels and assess metabolic status, including electrolyte imbalances.

Treatment

Management of calcium-channel blocker poisoning typically includes:

• Supportive Care: Monitoring vital signs and providing oxygen if necessary.
• Activated Charcoal: Administered if the patient presents within a few hours of ingestion to limit absorption.
• Intravenous Fluids: To support blood pressure and hydration.
• Medications: Calcium gluconate or calcium chloride may be administered to counteract the effects of the blocker. In severe cases, vasopressors may be required to manage hypotension.
