High-Dose Insulin for Hyperkalemic Cardiac Arrest

Area of Science:

• Cardiology
• Emergency Medicine
• Nephrology

Background:

• Hyperkalemic cardiac arrest presents diagnostic and management challenges.
• Restoring normal cardiac rhythm is often delayed until potassium levels decrease.
• Current treatments can be slow to reduce potassium levels.

Purpose of the Study:

• To describe the successful management of hyperkalemic cardiac arrest using high-dose intravenous insulin.
• To highlight an alternative treatment approach for hyperkalemic cardiac arrest.

Main Methods:

• Case report of two patients with witnessed hyperkalemic cardiac arrest.
• Management included conventional advanced cardiac life support.
• Unconventionally high doses of intravenous insulin were administered.

Main Results:

• Both patients survived the witnessed hyperkalemic cardiac arrest.
• High-dose insulin contributed to the successful resuscitation.
• This approach may expedite potassium level normalization.

Conclusions:

• High-dose intravenous insulin can be a life-saving intervention in hyperkalemic cardiac arrest.
• This strategy may offer a faster alternative to conventional treatments.
• Further research is warranted to explore optimal dosing and efficacy.
