Clinical Case Reports
|September 28, 2020
Summary
Severe hyperkalemia caused hemodynamic instability and bradycardia in a patient with diabetic ketoacidosis and acute kidney injury. Drug interactions can trigger life-threatening hyperkalemia, highlighting the importance of ECG monitoring and prompt treatment.
Area of Science:
- Internal Medicine
- Cardiology
- Nephrology
Background:
- Diabetic ketoacidosis (DKA) and acute kidney injury (AKI) are significant comorbidities.
- Polypharmacy is common in patients with multiple chronic conditions.
Observation:
- A case of severe hyperkalemia presenting with hemodynamic instability and bradycardia is described.
- The acute onset was triggered by DKA and AKI in the context of polypharmacy.
Findings:
- Severe hyperkalemia can lead to life-threatening bradycardia and hemodynamic compromise.
- Drug interactions are a frequent cause of iatrogenic hyperkalemia.
- Electrocardiogram (ECG) findings are critical for diagnosing hyperkalemia.
Implications:
- This case underscores the importance of recognizing drug interactions as a cause of hyperkalemia.
- Prompt ECG interpretation and management are crucial for patient outcomes.
- Treatment strategies for hyperkalemia must be tailored to clinical setting and available resources.

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
