This has been really fascinating to read, and I'm a bit ashamed to have only a tiny, N=1 point to bring to the table. But here goes ...
A lot of 'good' births on paper will have very different meaning to the woman involved. With DD2, I had a precipitous labour (90 mins from first twinge to baby) and arrived by ambulance. I climbed up onto the table, was examined, found to be complete with bulging membranes and two pushes later had my lovely, if 5 weeks early, daughter. My notes estimate my blood loss to be 100ml. As I pushed I was given the gas and air mouthpiece to bite on, but no gar and air.
Sounds pretty good, doesn't it? Healthy mum, healthy baby, minimum interventions - fab!! A midwife, reading my notes, told me how pleased I must have been to do it all naturally, and how lucky I'd been to avoid an epidural and all that.
I didn't feel very lucky. In fact, a few weeks after I was home I started a thread on here about whether or not it was normal or okay to scream during labour. This thread was prompted by the midwives who attended my delivery.
When I arrived at hospital, two midwives greeted the ambulancemen with rolled eyes and "so this is the one that called the ambulance. You do know it's not a taxi, don't you love?". I got further rolled eyes when I walked over to the bed, and with a sigh one midwife said she would check me to see if I should be sent home. At this point, she clearly felt waters and/or head, I'm not sure, but there was suddenly frantic activity. Nobody told me what was happening for a good few minutes, although most effort was devoted to telling me to sit absolutely still whilst the attached two monitoring belts. Predictably, the baby was too far down to get a good trace, but it did not stop them telling me not to move a muscle which as anyone would agree is bloody hard when you're about to have a baby. The midwife then re-checked me (why?) mid contraction, whereupon I screamed. She took her hand out sharply, my membranes ruptured and she informed me that I should push. I asked about pain relief and was given the gas and air mouthpiece to bite on but no gas and air as I in their opinion "didn't need it". As I pushed, I screamed again and the midwife sternly informed me that I was wasting my energy, to calm down and think about pushing. Another loud push later, and it was over.
I felt like an absolute fraud and a failure. I felt like I'd been an inconvenience to the midwives when I arrived, then a failure in their eyes for not being quiet and getting on with it. The birth was fast and furious but with the right support it could and should have been fanrastic - it had all the makings of one of those textbook births that DH learned about in medical school. Instead the feelings of shame associated with the event are only just now, a year on, starting to fade. I wished, and still wish, that I had simply stayed at home and given birth on my own / with DH's help.
That probably wasn't a point particularly well made (waffly, but mumsnet is a great place for birth catharsis) but what I meant to show is that a physiologically 'normal', no intervention birth in the statistics might mean something completely different to the mum - just as one medicalised up to the eyeballs (e.g. mine with DD1) could be fabulous. The common denominator in both occasions was a fabulous/not so fabulous midwife. I really wish more questions were asked about birth satisfaction. Whilst the results are suggestive of a complex interaction of factors(e.g. Hodnett, E. (2002) Pain and women's satisfaction with the experience of childbirth: a systematic review. American Journal of Obstetrics & Gynecology Volume 186, Issue 5, Supplement , Pages S160-S172) more needs to be done to elucidate these and to ensure they are reflected, as far as is possible, in current practice.
