Acute C4 Ingestion and Toxicity: Presentation and Management

Area of Science:

• Toxicology
• Military Medicine
• Emergency Medicine

Background:

• Composition C4 is a plastic explosive, with hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) as its active component.
• Limited data exists on the clinical effects and management of ingested C4.
• Understanding RDX toxicity is crucial for military and emergency medical personnel.

Purpose of the Study:

• To provide a comprehensive overview of human exposure to cyclonite/RDX from C4 ingestion.
• To outline the clinical manifestations and toxicological effects.
• To discuss essential management strategies for C4 exposure.

Main Methods:

• Literature review utilizing MEDLINE and Google Scholar.
• Keywords included "C4 ingestion", "RDX exposure", and "cyclonite toxicity".
• Inclusion of case reports, series, animal studies, clinical guidelines, and reviews.

Main Results:

• Few studies report on C4 ingestion, with central nervous system (CNS) effects being most common.
• Renal and gastrointestinal symptoms are also frequently observed.
• Management priorities include airway control, seizure management, and fluid resuscitation.

Conclusions:

• Human exposure to RDX via C4 ingestion presents with significant CNS effects.
• The toxidrome is generally transient, with supportive care being the mainstay of treatment.
• Prompt medical intervention focusing on critical symptoms improves outcomes.
