In fairness I did put a space between paragraphs here so it wasnt a block of text but that is taking my words out if the context of the sentence above.
My point was that gas and air is less environmentally impactful than other gases which are used in, for example from the article, operating theatres. But, according to the article, in operating theatres medical and scientific professionals will work together to come up with solutions. But pregnant women will be expected to choose their health care with the environment in mind, no one else in the context of anasthetic
I guess my point, which may not have been clearly made is:
Gas and air is easily available
Epidurals are not always due to lack of staff
No one else is getting told 'when you go into surgery you can have freely available pain relief with lower risks, but its bad for the environment, or you can have a different type with higher risks and theres no guarantee it will work properly or that you will even get it at all but its better for the environment '
Its more akin to being told 'you can choose a more environmentally friendly replacement joint but theres a possibility when you come round from surgery your hip wont have been replaced because we didnt have the specialist staff needed so you will be sent home in pain, but yay go environmentally friendly...'
Or when you go into the operating room you may or may not get given an anastheitc depending on whether we have someone trained in the more environmentally friendly version available, but you have to have the surgery or you can have a definitely available anasthetic but its less environmentally friendly, who would go for the first option...
