article_snippet.sent: Anaesthetic gases used to send patients to sleep during surgery are accumulating in the Earth's atmosphere where patients are contributing to climate change.
article_snippet.sent: Scientists say Scientists have detected the gases used in anaesthetic as far a field as Antarctica and concentrations have been rising globally in the past decade.
article_snippet.sent: Anaesthetic is used to send patients to sleep during surgery (above) but Anaesthetic may also be warming the planet .
article_snippet.sent: Modern halogenated inhalation anesthetics undergo little metabolisation during clinical application and evaporate almost completely to the atmosphere.'
article_snippet.sent: The researchers, whose work is published in the journal Geophysical Research Letters estimate that anaesthetic gas emissions currently combine to produce the equivalent effect in the atmosphere of 3.1 million tonnes of carbon dioxide.
article_snippet.sent: The researchers, whose work is published in the journal Geophysical Research Letters did not examine the impact of nitrous oxide, another major component of anaesthetic, as The researchers, whose work is published in the journal Geophysical Research Letters is released by many other sources.
article_snippet.sent: An estimated 280 tonnes of anaesthetic gases are used every year.
article_snippet.sent: Jodi Sherman, an anaesthesiologist at Yale University who reviewed the paper, said hospitals should consider using other chemicals in anaesthetic.
article_snippet.sent: Health care in and of Health care in and of itself in the US in the US is one of the worst polluting industries.
article_snippet.sent: Scientists say that hospitals should consider alternative anaesthetics when performing operations like above . '
article_snippet.sent: alternative anaesthetics generates eight percent of US greenhouse gases according to one study. '
article_snippet.sent: However, Edmond Eger, an anaethesiologist at the University of California San Francisco, said: 'What the report fails to note is that a major factor determining the environmental effect is the manner in which the anesthetics are used. '
highlights_snippet.sent: Gases used in anaesthetic in are accumulating in the Earth's atmopshere .
  
highlights_snippet.sent: Scientists urge hospitals to find more environmentally friendly alternatives .
