ICD-10: T44.7X2

ICD-10 code T44.7X2 refers specifically to "Poisoning by beta-adrenoreceptor antagonists, intentional self-harm." This classification is part of the broader category of poisoning diagnoses and is crucial for accurate medical coding, treatment, and epidemiological tracking.

Clinical Description

Definition

Beta-adrenoreceptor antagonists, commonly known as beta-blockers, are medications primarily used to manage cardiovascular conditions such as hypertension, heart failure, and arrhythmias. They work by blocking the effects of adrenaline on beta-adrenergic receptors, leading to decreased heart rate and blood pressure. However, in cases of intentional self-harm, these medications can be ingested in excessive amounts, leading to poisoning.

Symptoms of Poisoning

The clinical presentation of poisoning by beta-blockers can vary significantly based on the amount ingested and the specific type of beta-blocker. Common symptoms include:

• Cardiovascular Effects: Bradycardia (slow heart rate), hypotension (low blood pressure), and potential heart block.
• Respiratory Issues: Bronchospasm, particularly in patients with asthma or reactive airway disease.
• Neurological Symptoms: Dizziness, confusion, or even coma in severe cases.
• Gastrointestinal Distress: Nausea, vomiting, and abdominal pain may also occur.

Diagnosis

Diagnosis of beta-blocker poisoning typically involves a thorough clinical history, including the patient's medication use and the circumstances surrounding the ingestion. Laboratory tests may include:

• Serum Drug Levels: To determine the concentration of the beta-blocker in the bloodstream.
• Electrocardiogram (ECG): To assess for arrhythmias or conduction abnormalities.
• Blood Pressure Monitoring: Continuous monitoring is essential due to the risk of severe hypotension.

Treatment

Management of beta-blocker poisoning involves several critical steps:

1. Supportive Care: This includes monitoring vital signs and providing oxygen if necessary.
2. Activated Charcoal: If the patient presents within a few hours of ingestion, activated charcoal may be administered to limit further absorption of the drug.
3. Antidotes and Medications: In severe cases, glucagon may be used as an antidote, as it can counteract the effects of beta-blockade. Other medications, such as atropine for bradycardia or intravenous fluids for hypotension, may also be indicated.
4. Advanced Interventions: In cases of severe toxicity, advanced interventions such as pacing or even extracorporeal membrane oxygenation (ECMO) may be necessary.

Epidemiology

Intentional self-harm involving beta-blockers is a significant concern in mental health and emergency medicine. Understanding the patterns of such incidents can help in developing preventive strategies and improving mental health support systems.
