Just have to speak from a midwives point of view. I know this was more aimed at dating scans and nuchal translucency scans etc but if a woman came in labouring and hadn't had a scan thats the first thing we would do to ensure the placenta was in a safe spot for delivery. I think its very fortunate we live in times where this is an option as it does save lives. I personally know of several people who had undiagnosed placenta previa's two who died (with the baby of course) and all the others also lost their babies. This was prior to routine ultrasounds. They are all elderly now except my aunty (48) who had a stillborn DD 16years ago prior to routine scans. She presented as normal in labour with her 3rd baby and was labouring well until she had a massive bleed very suddenly. She had an emergency C/S but it was too late to save her bub.

I can see how early scans are not neccessary and alot inbetween but I would be concerned about a woman who presented with no scans the entire pregnancy. Yeah most of the time it would be fine and a healthy baby would be delivered but what about the others which wouldn't be? And some conditions in babies that have paeds at delivery, surgery ready etc knowing bub has a problem that can be treated? It is horrible to be in that position as a mother or health professional at delivery when a potentially treatable condition was undiagnosed and a baby/mother was lost or left with a disability as the cause wasn't known. I have been in that position and its not nice. Then usually there is an inquest into how it happened. Interesting thread!
