There was a small reduction in the length of the third stage of labour and also in the amount of blood loss when cord drainage was applied compared with no cord drainage. The clinical importance of such observed statistically significant reductions, is open to debate. There is no clear difference in the need for manual removal of placenta, blood transfusion or the risk of postpartum haemorrhage. Due to small trials with medium risk of bias, the results should be interpreted with caution.

Bleeding is a common feature of early pregnancy affecting about one-fifth of pregnant women in the first trimester. The chance of miscarriage after bleeding and a live fetus at scan has not previously been defined precisely. The purpose of this study was to evaluate the outcome of early pregnancies with a viable singleton fetus that had been complicated by bleeding. A prospective study was performed on 370 women with a singleton live fetus who had presented to the early pregnancy assessment clinic (EPAC) with vaginal bleeding. Women were grouped into light, moderate and heavy loss according to the self-assessed degree of vaginal bleeding. The women were also categorised according to the presence or absence of an intrauterine haematoma. The overall spontaneous miscarriage rate in the study was 11.1%; almost 90% of pregnancies continued to viability. Women with moderate or heavy bleeding had more than twice the rate of miscarriage compared with those with light bleeding. A total of 14% of the women had an intrauterine haematoma and those women were 2.6 times more likely to miscarry than those without (23% vs 9%). This relationship appeared to hold true even after controlling for blood loss. The data presented can be used to guide women with a live fetus about the chance of miscarriage after an episode of vaginal bleeding. We propose that a large multi-centre study should be undertaken to define precisely the risk miscarriage for each gestational week according to a range of clinical and ultrasound characteristics.
