ICD-10: T46.4X3

Poisoning by angiotensin-converting enzyme (ACE) inhibitors, classified under ICD-10 code T46.4X3, typically occurs due to an overdose or inappropriate use of these medications. This condition can arise from various scenarios, including accidental ingestion, intentional self-harm, or assault. The management of such cases requires a comprehensive approach that includes immediate medical intervention, supportive care, and monitoring.

Understanding ACE Inhibitors

ACE inhibitors are commonly prescribed medications used to treat conditions such as hypertension, heart failure, and certain kidney diseases. They work by inhibiting the enzyme that converts angiotensin I to angiotensin II, leading to vasodilation and reduced blood pressure. Common ACE inhibitors include lisinopril, enalapril, and ramipril.

Clinical Presentation

Patients experiencing poisoning from ACE inhibitors may present with a range of symptoms, including:

• Hypotension: Significantly low blood pressure is a common and serious consequence of overdose.
• Bradycardia: A slower than normal heart rate may occur.
• Dizziness or fainting: Due to reduced blood flow to the brain.
• Cough: A persistent dry cough can be exacerbated in some cases.
• Angioedema: Swelling of the deeper layers of the skin, particularly around the eyes and lips, which can be life-threatening if it affects the airway.

Standard Treatment Approaches

1. Immediate Medical Attention

In cases of suspected poisoning, immediate medical evaluation is crucial. Emergency services should be contacted, and the patient should be transported to a healthcare facility.

2. Stabilization

Upon arrival at the hospital, the following steps are typically taken:

• Airway Management: Ensuring the airway is clear and providing oxygen if necessary.
• Intravenous Access: Establishing IV access for fluid resuscitation and medication administration.
• Monitoring Vital Signs: Continuous monitoring of blood pressure, heart rate, and oxygen saturation.

3. Decontamination

If the ingestion of ACE inhibitors occurred recently, activated charcoal may be administered to limit further absorption of the drug. This is most effective within one hour of ingestion.

4. Supportive Care

Supportive care is essential in managing symptoms:

• Fluid Resuscitation: Administering IV fluids to combat hypotension and maintain blood pressure.
• Medications: In severe cases, vasopressors may be required to stabilize blood pressure. Atropine can be used for bradycardia if necessary.

5. Monitoring and Observation

Patients should be closely monitored for complications, including renal function tests, electrolyte levels, and signs of angioedema. Hospitalization may be required for observation, especially if the overdose was significant.

6. Psychiatric Evaluation

In cases of intentional overdose or assault, a psychiatric evaluation is essential to address underlying mental health issues and ensure the safety of the patient.

Conclusion

The management of poisoning by ACE inhibitors, particularly in the context of assault, requires a multifaceted approach that prioritizes immediate medical intervention, stabilization, and supportive care. Continuous monitoring and psychiatric evaluation are also critical components of the treatment plan.
