ICD-10: T46.5X2

The ICD-10 code T46.5X2 refers to "Poisoning by other antihypertensive drugs, intentional self-harm." This classification indicates a specific scenario where an individual has intentionally ingested antihypertensive medications with the intent to harm themselves. Understanding the standard treatment approaches for this condition is crucial for effective management and patient safety.

Overview of Antihypertensive Drug Poisoning

Antihypertensive medications are commonly prescribed to manage high blood pressure and can include various classes such as beta-blockers, ACE inhibitors, calcium channel blockers, and diuretics. Poisoning from these drugs can lead to significant cardiovascular and neurological complications, particularly when taken in overdose or with the intent of self-harm.

Initial Assessment and Stabilization

1. Emergency Response

• Call for Help: Immediate medical attention is essential. Emergency services should be contacted to transport the patient to a healthcare facility.
• Airway, Breathing, Circulation (ABCs): The first step in treatment is to ensure the patient's airway is clear, breathing is adequate, and circulation is stable. This may involve administering oxygen or performing CPR if necessary.

2. Triage and Evaluation

• History and Physical Examination: Gathering information about the specific antihypertensive drug(s) ingested, the amount, and the time of ingestion is critical. A thorough physical examination will help assess the severity of the poisoning.
• Vital Signs Monitoring: Continuous monitoring of vital signs, including heart rate, blood pressure, and oxygen saturation, is essential to detect any deterioration in the patient's condition.

Decontamination

1. Activated Charcoal

• If the patient presents within one hour of ingestion and is alert, activated charcoal may be administered to limit further absorption of the drug. The decision to use activated charcoal should be made cautiously, considering the patient's airway protection and the specific drug involved.

2. Gastric Lavage

• In cases of severe overdose or when the patient is unconscious, gastric lavage may be considered, although its use is less common due to potential complications and the availability of more effective treatments.

Specific Antidotal Therapy

1. Supportive Care

• Fluid Resuscitation: Intravenous fluids may be necessary to manage hypotension and maintain adequate perfusion.
• Electrolyte Monitoring: Regular monitoring of electrolytes is crucial, as antihypertensive overdoses can lead to imbalances, particularly with diuretics.

2. Pharmacological Interventions

• Vasopressors: In cases of severe hypotension, vasopressors such as norepinephrine may be required to stabilize blood pressure.
• Atropine: For bradycardia (slow heart rate), atropine may be administered to increase heart rate.
• Calcium Gluconate: In cases of calcium channel blocker overdose, calcium gluconate may be used to counteract the effects of the drug.

Psychiatric Evaluation and Follow-Up

1. Mental Health Assessment

• Following stabilization, a comprehensive psychiatric evaluation is essential to address the underlying issues related to the intentional self-harm. This may involve collaboration with mental health professionals.

2. Safety Planning
