Summary
Hyperinsulinemic-euglycemic therapy effectively treated a patient with calcium channel blocker overdose unresponsive to conventional treatments. This approach improved both neurologic and hemodynamic status, offering a new treatment avenue.
Area of Science:
- Cardiology
- Toxicology
- Endocrinology
Background:
- Calcium channel blocker (CCB) overdose can cause severe hypotension and bradycardia.
- Conventional treatments including fluids, calcium, glucagon, and vasopressors are often insufficient.
Observation:
- A 77-year-old male presented with hypotension and bradycardia after nifedipine and atenolol overdose.
- Standard therapies failed to stabilize the patient's hemodynamic condition.
Findings:
- Hyperinsulinemic-euglycemic therapy (HIET) was initiated.
- HIET led to significant improvement in the patient's neurologic and hemodynamic status.
Implications:
- HIET may be a beneficial alternative for refractory CCB intoxication.
- Understanding the role of hypoinsulinemia in CCB toxicity is crucial for treatment.
- This case highlights a potential novel therapeutic strategy for severe CCB overdose.
