Detection of Deaths Caused by Hyperkalemia

Area of Science:

• Forensic Pathology
• Toxicology
• Physiology

Background:

• Potassium is primarily intracellular, with gradients crucial for cellular function.
• Disrupted gradients cause hyperkalemia (elevated extracellular potassium).
• Hyperkalemia symptoms include cardiac arrhythmias and muscle weakness.

Purpose of the Study:

• To review the challenges in post-mortem diagnosis of hyperkalemia.
• To explore novel methods for detecting hyperkalemia in forensic investigations.

Main Methods:

• Review of existing literature on hyperkalemia.
• Discussion of post-mortem potassium accumulation.
• Evaluation of alternative diagnostic techniques.

Main Results:

• Hyperkalemia deaths are often misdiagnosed due to non-specific symptoms.
• Current potassium testing methods have limitations.
• Post-mortem potassium levels can increase in various tissues.

Conclusions:

• Histopathological analysis, vitreous potassium, and aldosterone levels show potential for improved detection.
• Enhanced diagnostic approaches are needed for hyperkalemia fatalities.
• Accurate identification of hyperkalemia is crucial for forensic casework.
