This is the most recent of various research and is largely reassuring, although mostly on boys. The animal studies are quite concerning but I think much higher doses of anaesthetic were involved.
It sounds like some strategies for neuroprotection during anaesthesia are being studied but like everything it takes so long.
My 1 year old girl needs a procedure soon that can't wait until she is 3 and I know it's the right thing to do but I feel absolutely sick and not that reassured by "it's probably ok" although I know the drs looking after her are doing their best and the right thing. It's booked for later this month.
Does anybody have any reassuring stories? She's so perfect, I don't want her to change, though I know rationally she won't.
