Hemoperfusion in acute camphor poisoning.
Intensive Care Medicine
|January 1, 1988
Summary
Hemoperfusion effectively cleared camphor from plasma but did not significantly improve the clinical outcome in a severe camphor intoxication case. This suggests limited clinical benefit despite high clearance rates.
Area of Science:
- Toxicology
- Pharmacokinetics
Background:
- Camphor spirit intoxication can lead to severe neurological and respiratory complications.
- Effective detoxification strategies are crucial for managing camphor overdose.
Observation:
- A 54-year-old female presented with coma, seizures, and respiratory failure after ingesting camphor spirit.
- Gastric lavage and hemoperfusion were administered for detoxification.
Findings:
- Hemoperfusion achieved high plasma camphor clearance (89%-95%) but removed only 35 mg due to a large volume of distribution.
- Clinical status, including coma grade, showed no marked improvement despite hemoperfusion.
- Plasma elimination half-life remained unaffected, possibly due to enzyme saturation or incomplete absorption.
Implications:
- Hemoperfusion may have limited clinical efficacy in severe camphor intoxication.
- Further research is needed to optimize treatment strategies for camphor overdose.
- Understanding camphor's pharmacokinetic profile is essential for managing toxicity.
