Summary
Butane intoxication from lighter refills can cause fatal asphyxiation. This study found unexplained myocardial damage in fatal butane abuse cases, suggesting a novel toxic mechanism beyond simple asphyxia.
Area of Science:
- Toxicology
- Cardiology
- Forensic Pathology
Background:
- Butane abuse, often via inhalant use of lighter refill cans, presents a significant public health risk.
- Previous reports on butane intoxication primarily focused on asphyxial effects and cardiac arrhythmias.
- The mechanism underlying fatal outcomes in butane abuse remains incompletely understood.
Observation:
- Three cases of fatal butane intoxication are presented.
- Inhalant abuse involved direct spraying of butane from lighter refill cans.
- Autopsies revealed non-specific signs of asphyxiation, including petechial hemorrhages and pulmonary edema.
Findings:
- A key finding was the presence of hemorrhagic microruptures within myocardial fibers.
- These cardiac lesions were observed despite the absence of mechanical trauma.
- The observed myocardial damage suggests a direct toxic effect of butane on the heart muscle.
Implications:
- The findings suggest butane may have a direct cardiotoxic effect, leading to myocardial damage.
- This cardiotoxicity could be a significant factor in the fatal outcomes of butane intoxication.
- Further research is warranted to elucidate the precise mechanism of butane-induced myocardial injury and inform clinical management and prevention strategies.
