I am very suspicious about this
Has some NHS official (of which there are thousands) had some kind of nudge from a drug company, to steer women towards, well, drugs. Gas and air is of course a drug, but how profitable? Who profits? And are pethidine and epidurals more lucrative? But maybe I am over-sceptical. Certainly in regard to health-damage to the professionals, I would have thought the stress and overwork are of greater concern. If it's just a matter of B12 that could be replaced by supplements. Whatever, it is appalling and my heart goes out to those poor women labouring without pain relief. What horror story next, from our struggling NHS?
