Birth was one of the biggest causes of death for mother and child in the past because of:
Risk of infection (it wasn't until Semmelweis in the 19th century that people actually realised that they should be washing their hands before inserting them in women). Childbed or puerperal fever was a major cause of death.
Lack of antenatal care to pick up things like eclampsia, heart problems, diabetes, malformed pelvises, multiple births, HELLP syndrome etc.
Lack of anaesthetics, aseptic environment and antibiotics after C-sections and birth in general. Women with stuck babies could labour for days whilst their dead baby either rotted inside them or had them removed in pieces. Dehydration and exhaustion, blood loss or infection would often kill the mother.
Lack of skilled professionals. Lots of doctors left university to deliver babies having seen only one natural delivery. Midwives were discredited but at certain points in history you were more than twice as likely to die under the care of hospitals than giving birth at home, not least because you were exposed to unfamiliar germs and would often be sharing a bed with two other women in a filthy environment. When the hospital then became the place to be for upper and middle class mothers they often had again a higher death rate than the poorer women who had to stay at home. Doctors were the only ones allowed to use forceps and there is evidence from diaries that they used them to earn their bigger fee and justify their presence, rather than midwives who were skilled in other techniques.
Inability to deal with premature babies or birth defects.
No way of detecting things like rhesus incompatibility that can lead to stillbirth
Prevalence of diseases that are now treatable. Syphilis and other sexually transmitted infections, scarlet fever and the following rheumatic fever that damaged hearts. Rickets where the pelvis could become so malformed there was no way a baby could get out. Vaginal and uterine prolapse, fistulas. High blood pressure, undetected cancers/tumours or polyps.
Placenta previa, placental abruption could not be detected and prove fatal nowadays without scans.
Hemmorage-no way to stop this
Lack of universal medical care so many women were too poor to afford doctors and any intervention they might need
Martha Ballard-a midwife in colonial America delivered 996 babies in her lifetime. Out of those 996 births, four mothers died.
Most of those factors have now been removed through knowledge about bacteria etc and excellent ante-natal care. I was told about the small risk of haemorrage (lessened by the fact I had one successful birth with no problems) and the risk of shoulder dystocia (for which i had two or three of the risk factors) but I had confidence in my midwife that she could deal with this, she had done it before and was able to allay my fears.
There is no shame in having a C-section but it wouldn't have been my choice. But I wouldn't tell someone who was planning one or who had had one that they were wrong. I would have had one if it had been indicated as a necessity for me. Likewise medical intervention and a hospital birth.
I would expect other people to respect my choice.
Just read above- medical intervention can affect bonding with a baby, not in every case of course and other factors can be involved. But some interventions can interfere with the production of oxytocin and other 'love' hormones. A mother who has had intervention could find it more difficult (note not impossible) to have skin to skin due to either position, medication, the process of being stitched, having to have paeds work on the baby immediately etc. Also sometimes a mother who has gone through a difficult birth that has caused her emotional/physical pain afterwards may find it hard to accept the baby that caused that pain, no matter how taboo that sounds.
The organisations mentioned above do not advocate homebirth, no, but neither do they say its a dangerous thing to do. I would imagine that most members of the RCOG don't regularly attend homebirths and their comment reflects that, anything further would surely be seen as a criticism of their workplace and methods.
