Protecting Mother and Baby during Second Stage of Labour

I recently had a client who laboured slowly.  Her 2nd stage was prolonged, the fetal heart never once faltered and we protected her autonomy to give birth following the urges her body displayed during contractions. The mother needed the time to accustom herself to the strong sensations in her pelvic area as she had been sexually abused as a young child. The mother needed to realise that the strong sensations were not associated with that traumatic experience. We were very gentle with her; she was empowered and gave birth spontaneously to a healthy baby boy.

How does a midwife explain a slow labour or a long ‘second stage’? The point is, a mother who is forced to push (coached pushing) tires more easily and is less able to recover in-between the contractions, as is her unborn child. A mother who follows the urges of her body may have a longer second stage and give birth to a baby with a good apgar score, equal to that of a baby born to a mother coached during a shorter second stage of labour. Coached pushing  is used in the vast majority of hospital births. Several studies show that supine (lying or reclining on your back) pushing is not beneficial and can even be harmful to the mother and the baby. Pushing in a supine or even a semi reclining position works against gravity and decreases blood pressure, which can lead to fetal exhaustion. There is more damage to the pelvic floor,  an increased incidence of episiotomy, increased use of vacuum/forceps, and it is more painful for the mother.

Midwifery is both an art and a science and part of that art, in the present climate, seems to be to prevaricate in order to align ourselves with what obstetric theory advises we should be doing. According to the current practice second stage should take approximately one hour. I understand that with large numbers of women, protocols, systems and services need to be in place to ensure the safety of the general populace. Systems and protocols provide safe guidelines to follow in these situations but may preclude honouring those women who deviate from the norm. Medical science does not teach that second stage only begins when the head descends on the pelvic floor, nor does it teach spontaneous expulsion of the baby.

How does one teach, to midwifery and medical students alike, the difference between an obstructed labour or a mother who just needs time. When the fetal head is still high, even though a mother may be fully dilated, time should be given to allow descent of the head onto the pelvic floor. For some women this takes longer than for others. Pushing starts when the mother feels spontaneous urges, not when the midwife or obstetrician decides pushing should occur

Having said all this, I fully recognise that mothers and babies may be at risk when labours extend way off the partogram, although this occurs often in over utilised and understaffed services or in rural areas, where mothers are young, malnourished, there is poor transport etc. Another thing: students are not taught how to read the outward behaviour of women in labour, such as her facial expressions, body movements and sounds. Changes in behaviour during labour are clues to the experienced midwife as to the progress of labour. I remember approaching a patient who was clearly exhibiting outward behaviour that suggested she was close to spontaneous expulsion and the attending obstetrician was insisting on attaching a fetal scalp probe. I asked him to refrain and told him the woman was about to give birth. Soon after he left she gave birth to a healthy baby.

Women need privacy, quietness, time and gentle encouragement to complete the second stage of labour spontaneously and birth their babies with their own efforts. This gives women enormous satisfaction and pleasure once the baby is safely in their arms.

I attach the following references for spontaneous pushing and position during 2nd stage labour, but these do not yet solve the problem of the length of time that can be allowed from full dilatation to expulsion of the baby during 2nd stage.
