Suicide by Inhalation of Suffocative Gas | The Bulletin of Legal Medicine

Occupational and Epidemiological Studies No data were available. Hence, this study does not provide an adequate starting point for deriving AEGL-3 values. Butane was negative in the bacterial reverse-mutation assay Ames test.

Mortality from butane in mice and rats is preceded by CNS effects. Because details of the study were lacking and because the tests were conducted in anesthetized dogs, no clear conclusions can be drawn from this study.

The concentrations were analyzed periodically and adjustments made to maintain the predetermined concentrations. Butane is also used as lighter fuel for a common lighter or butane torch and is sold bottled as a fuel for cooking, barbecues and camping stoves.

A auu state is reached within 30 min, and the effects are considered to be concentration dependent. The effects are attributed to butane itself and no relevant differences in kinetics are assumed, so only small interindividual differences are expected. The female child was delivered normally and appeared in good condition. Hence, the rationale described in Section 6. Because the anesthetic effects of butane are considered to be predominantly concentration dependent, a total uncertainty factor of 3 is considered sufficient for toxicokinetic and toxicodynamic differences between individuals and interspecies differences.


It was highly Jose Quero, M. What ibtoxication can expect when you look for help Bufane a service. At seven days of age an electroenceph- alogram showed slow and low-voltage activity over both hemispheres.

Nihon Hoigaku Zasshi; The case reports do not provide adequate quantitative data to derive AEGL-3 values. Data Quality and Research Needs The database for butane is poor and important studies date back to the s or s.

The system operating pressure for butane is lower than for the halomethanes, such as Rso R systems such as in automotive air conditioning systems, when converted to pure butane will not function optimally and therefore a mix of isobutane and propane is used to give cooling system performance comparable butaje R The concentration-response curve appears to be very steep indicating that a large factor s unnecessary. In Virginia, 39 cases of people who likely died as a direct consequence abusing an inhalant were found between and Database is relatively poor but the values are supported by the available animal data.

If the person gets excited, startled or participates in any sudden physical activity after inhaling butane, the heart can fail to pump blood. On the action of trichloride of phosphorus on the salts of the aromatic monamines”.

Butane is a colorless gas with a faint disagreeable odor, although it is considered to be odorless by some. A year-old boy who was known to inhale butane from a plastic bag had bilateral hemispheric infarcts Bauman et al.

Butane | C4H10 – PubChem

LPG is commercially available as propane, butane and propane-butane mixtures. Los autores creen que la malformacidn fuk debida a la anoxia intrauterina que t w o lugar durante el desarrollo cerebral del feto. Die Mutter hatte im sechsten Schwangerschaftsmonat versehentlich Butan inhaliert. Light anesthesia can be considered serious enough to impair escape, and could be used as basis for AEGL In this form it is often mixed with small amounts of hydrogen sulfide and mercaptans which will give the unburned gas an offensive smell easily detected by the human nose.


Our patient had no evidence of fetal distress at birth, and ay infection as the cause of the brain lesions was excluded. Hydranencephaly after Maternal Butane-gas Intoxication during Pregnancy.

Suicide by Inhalation of Suffocative Gas

Several alkanes C 3 to C 7 were studied in intoxictaion experiment and more severe effects were reported for hexane and heptanes, suggesting that if effects were observed with butane they would have been described more explicitly. Most rats died during intoxicatio third or fourth hour of exposure. On admission to the hospital, there was no spontaneous respiration; a CT scan showed a very tight, swollen brain and an electrocardiogram showed sinus tachycardia with marked T-wave inversion in the anterolateral leads.

Jpn J Legal Med ; Butane could have caused cardiac sensitization, and a surge of adrenaline would have caused the arrhythmia rather than hypoxic arrest.

Mice Shugaev exposed mice sex and strain not specified to various butane concentrations for 2 h. Patty and Yant studied the warning properties of several alkanes, including butane. BeH 2 covalent metal hydride Right:
