Key Aspects of Ingestion Work-up
- History and physical exam are crucial.
- Stratify acute or chronic ingestions.
- Consider baseline medications and coingestants.
- Perform initial screening examination to identify immediate measures for stabilization.
Diagnostic Studies
- Pulse oximetry, continuous cardiac monitoring, ECG, capillary glucose measurement.

Differentiating CCB vs. Beta-Blocker Overdose
- ECG findings: PR interval prolongation and Bradydysrhythmia suggest CCB poisoning.
- Hyperglycemia in non-diabetic patients may indicate CCB overdose

- Initial resuscitation and stabilization
- ABC approach
- Consult Poison Control Center
- Empiric use of glucagon, IV fluids, and vasopressors
- Consideration of orogastric lavage and activated charcoal
Specific Medical Therapies
- Vasopressors: norepinephrine/epinephrine infusion
- Atropine for bradycardia
- IV calcium salts to overcome cardiovascular effects
- High-dose insulin and dextrose for myocardial function
- Investigational therapies: methylene blue, lipid emulsion
Procedures
- Transvenous pacemaker placement if needed
- ECMO in refractory...
