General anaesthetic


Hi All! After some advice. Due to undergo an endometrial ablation under general anaesthetic. (Hopefully to help address chronic iron deficiency anaemia) Aside from having my b12 jab afterwards as opposed to before....anything else I should be aware of in relation to general anaesthetic? Last GA I had was over 20 years ago before I had all these health issues. Mildly anxious. TIA 😊

Hi Portia1974

Nitrous oxide is a super-oxidiser when it comes to B12 and converts it to a form that the body cannot use, so if you had an absorption problem and couldn't replace your the oxidised B12 with new B12 then it would be a permanent problem.

Nitrous oxide isn't a local anaesthetic so suspect it isn't used for most day surgery but if you have any doubt then I would suggest that you contact the hospital/surgery where the operation was done and ask them to clarify.

I am not a medically trained person but I've had Pernicious Anaemia (a form of B12 deficiency) for more than 46 years.

I wish you well.

Thanks Clive. Haven't had the op yet. Just getting my research in ahead of it so I'm prepared. Thanks for the info 😊 Wishing you well too 😊

When I had an op. last year I told the anaesthetist I had B12 deficiency, and asked him if I could not have Nitrous Oxide. He knew all about it, and made a note not to give it to me.

Thanks lovely😊

Good luck
