I'm considering declining VEs in labour, as it seems to me that the information they provide (2cm? 5cm?) is of no benefit to ME as the labouring mother. In fact, last time they were extremely demoralising and pretty much precipitated a big meltdown to be told I wasn't progressing, where previously I'd been coping quite well. My MW has only really managed to articulate the benefit to her, as in, "I'll know whether you're really in labour or not" (aka as I can justify buggering off for a while).
From what I've read, the 'purple line' is quite a good indication of dilatation, and there are various other signs of progression of labour.
Besides, what can one DO with the info? 2cm to 10 cm can take 2 hours in one woman, but 3 days in another, so how can any meaningful decisions be reached on that basis alone?
The only thing that concerns me is the whole 'pushing too early' scenario, when there may still be a cervical lip. (check out the MN official useful info on this topic!) Does this happen often? Are our bodies so badly designed that we feel the natural urge to push before it is safe, and need to resist our own instincts? My common sense questions this idea that women need some external third party to tell them when they can and can't push, and give them permission. I'd have thought that evolution kinda took care of that instinct properly.
But I'm open-minded, and want to hear the case for and against VEs. Do you reckon they are yet another intervention that, actually, are rather unnecessary, or do they provide vital info that we can't do without?
