Fluoride Toxicity Clinical Presentation
- Author: Richard D Shin, MD; Chief Editor: Asim Tarabar, MD more...
Determine the exact nature, amount and time of exposure or ingestion. Query patient, bystanders, paramedics, and family members regarding specifics of exposure or ingestion, including possible co-ingestants. Delayed clinical presentation of significant exposures is quite common.
Monitor and watch patients in the emergency department for 6 hours before possible discharge. Patients may be discharged if asymptomatic and ingestion was less than 3 mg/kg by accurate history. If a patient presents with persistent signs and symptoms, admit to a monitored bed.
Gastrointestinal signs and symptoms, as follows, predominate:
- Abdominal pain
- Mucosal injury
Neurologic effects are as follows:
- Muscular spasm
- Tetanic contractions
- Hyperactive reflexes
- Muscle weakness
Cardiovascular effects are as follows:
- Widening of QRS
- QTc prolongation
- Various arrhythmias
- Cardiac arrest
