We propose to conduct a randomised-controlled study to investigate whether adopting McRoberts’ position, after 45 minutes of active pushing with no signs of progress, can increase the probability of vaginal delivery, preventing the need for forceps or vacuum assistance. In our study we will allow 45 minutes of pushing before a further 45 minutes of either the same, or our intervention (McRoberts’ manoeuvre).
