Dystocia, shoulder dystocia and obstetric trauma are all increased in post-term pregnancy . Here, the risks increase with increasing fetal weight, but gestational age remains a risk factor independent of birthweight. In a case-matched study of 285 women with uncomplicated singleton post-term pregnancy and spontaneous onset of labour and 855 women with uncomplicated singleton term pregnancy, Luckas et al.  showed that Caesarean section was significantly more common in women with post-term pregnancy (relative risk = 1.90, 95% CI = 1.29-2.85). The increase was equally distributed between Caesarean sections performed for failure to progress in labour (RR = 0.74, 95% CI = 1.02-3.04) and fetal distress (RR = 2.00,95% CI = 1.14-3.61). This finding is consistent with the hypothesis that some cases of prolonged pregnancy are associated with a defect in the physiology of labour, in addition to any increase in risk of fetal hypoxia. However, the possibility of bias in management arising out of the knowledge that a pregnancy is post-term cannot be excluded as a factor in the increase in Caesarean section rates.
