Declarations

:

: Ethics approval was obtained from the London School of Hygiene and Tropical Medicine (ref: 15194), as well as all relevant national and local ethics committees. If women are in the active stage of labour and able to give fully informed consent, written consent is obtained. However, many women arrive at hospital in the second stage of labour. Because these women are more likely to be anaemic and more likely to have a PPH, it is important to include them in the trial. However, they may not have the physical/mental capacity to give fully informed consent due to the pain of labour, poor health, or the urgency of the situation. In these cases, a clinician will assess the capacity of the woman and the most appropriate consent procedure is used, which includes giving brief verbal information, obtaining witnessed verbal agreement and delaying written consent until women regain capacity. The patient information sheet and consent form can be found at .
