No AEGL-1 effects at 10, ppm for 10 min. Metabolism Tsukamoto et al. What you can expect when you look for help Find a service.
Butane | C4H10 – PubChem
Concentration-time mortality response relationship of irritant and systemically acting vapours and gases; pp. Odor thresholds and irritation levels of several chemical substances: A number of fatal and nonfatal cases related to butane abuse or suicide attempts have been described. During his hospitalization his cardiac status improved but brain functions remained disturbed Bauman et al.
The authors found an zyxwvu Grasp and sucking reflexes were present. Light and complete anesthesia occurred in mice exposed to initial concentrations of butane atppm within 25 min andppm within 15 min. Butane concentration in exhaled breath decreased rapidly to less than 5 ppm, 20 min after exposure ended.
Froth was present in the trachea and bronchi; pulmonary edema was also reported. Tolerance to butane can develop quickly meaning that more of the substance is required to get the same effect. Data on intoxication by liquefied petroleum gas a mixture of predominantly propane and butane in varying proportions were not considered. Estos hallazgos eran compatibles con hidranencefalia.
inttoxication On the action of trichloride of phosphorus on the salts of the aromatic monamines”. Blood concentrations of butane also decreased rapidly to less than 0. Death was attributed to multiple organ failure involving the CNS brain edemacardiovascular system, pulmonary system, and the liver.
Suicide by Inhalation of Suffocative Gas
No data other than that described in Sections 3. Most deaths attributed bbutane butane use are caused by SSDS. Case Reports Substance abuse is one of the predominant causes of death from butane intoxication. A steady state is reached within 30 min, and the effects are considered to be concentration dependent. However, the experimental procedure is poorly described but suggests that reported concentrations are probably initial concentrations in a closed-chamber setting.
Subsequently she was not under regular obstetric supervision until inroxication 39th week, when an intra-uterine ultrasound scan showed an almost complete absence of brain tissue Fig. The results of the key study in mice are comparable with the results from a second study in mice.
Suicide by Inhalation of Suffocative Gas.
Suicide by Inhalation of Suffocative Gas | The Bulletin of Legal Medicine
Phenomenology intoxicatio intoxication with toluene-based adhesives and butane gas; pp. LPG, butane, propane, suicide, autopsy. A year-old boy was found unresponsive and cyanotic after reportedly inhaling butane from a plastic bag. Concentrations of hydrocarbons in tissues as a measure of toxicity. Guinea pigs exposed for 5 min at 50, ppm showed no significant effects.
Two relevant animal studies are available, a study with rats and mice by Shugaev and a study in mice by Stoughton and Lamson Thus, the concentration of butane will have decreased during buatne.
He had a history of butane abuse. The subsequent cavitation Antonio Gonzalez, M.
Experimental Studies Patty and Yant studied the warning properties of several alkanes, including butane. No deaths occurred in mice exposed for intoxicwtion h atorppm. Surviving mice recovered rapidly, within 5 min after exposure ended Stoughton and Lamson Butae dogs were exposed to butane by a tracheal cannula, and epinephrine 0.
Butane is a highly flammable, colourless, odourless gas. Retrieved 11 December The cause of death was cardiac arrhythmia and lung edema. Retrieved 20 September Other viscera were reported to be unremarkable.
Cardiopulmonary resuscitation was commenced. Shugaev exposed mice and rats to butane for 2 and 4 h, respectively. Very pure forms of butane, especially isobutane, can be used as refrigerants and have largely replaced the ozone-layer-depleting halomethanesfor instance in household refrigerators and freezers. The only study with human volunteers Patty and Yant is rather old and focused on the warning properties of butane.
Not applicable Time scaling: Normal butane can be used for gasoline blending, as a fuel gas, fragrance extraction solvent, either alone or in a mixture with propaneand as a feedstock for the manufacture of ethylene and butadienea key ingredient of synthetic rubber.
Propane and isobutane were also detected. Summary A number of fatal and nonfatal cases related to butane abuse or suicide attempts have been described.
Quantitative human data include an old study with human volunteers focused on the warning properties of butane. Experiments with dogs Chenoweth ; Krantz et al. However, it might be an indication that mice are more susceptible to butane toxicity, because a steady state is expected to be reached rapidly butwne butane see Section 6. Four human subjects 3 male, 1 female; years of age were exposed to butane at ppm for 4 h. The infant intoxcation born at 39 weeks.
