Thanks Sally. 

I also read this article but wondered at the paucity of information regarding the position of the birthing woman, certainly not difficult to establish given the retrospective nature of the study. Considering most midwives and most women would already know of the effects of different foetal positions on length of labour (and I really dislike the use of mal as a way of describing foetal position, such a threatening word, and I noticed that the problem of such positions remains an “obstetric challenge” and never mind the woman).   I suggest a more useful study would be to forget about determining times ad nauseam and look at the effects of maternal position when the foetus is lying less favourably, but perhaps that’s coming…!  Certainly enough Midwives have looked at the issue from a research perspective.

 

Apologies for the negative note to this post, but I am feeling slightly cynical today,

Foetal malposition lengthens labour and poses maternal risks

Assessing the impact of foetal position at full dilatation on labour duration and indicators of maternal morbidity.

Pregnant women with occiput posterior or transverse position at full dilatation are at increased risk of a prolonged second stage of labour and of maternal morbidity, research shows.

"Since Mauriceau's classical work was published in 1681, the occiput posterior and transverse malpositions have remained an obstetric challenge," write Julie Senecal (Laval University, Canada) and colleagues.

For the current study, the team assessed the effect of such foetal positions on the duration of the second stage of labour and on indicators of maternal morbidity, using retrospective data for 210 women whose foetus was in the posterior position, 200 with it in a transverse position, and 1198 with an anteriorly positioned foetus.

This revealed that foetal malposition at full dilatation was associated with significant maternal morbidity, including increased risks of instrumental delivery, caesarean delivery, oxytocin administration, episiotomy, and blood loss exceeding 500 ml.

In addition, the duration of the second stage of labour with early or delayed pushing was higher for transverse (3.6 hours and 2.5 hours, respectively) and posterior (3.8 hours and 3.0 hours, respectively) positions than for the anteriorly positioned group (3.1 hours and 2.2 hours, respectively).

"Guidelines that propose norms for expected labour duration should take into consideration position of the foetal head at full dilatation and the strategy of pushing," conclude the researchers.
