What is the best treatment to reduce the need for caesarean section in nulliparous women at term with delayed first stage of labour?

* Prolonged labour is associated with adverse outcomes for mother and fetus, and intravenous oxytocin is the mainstay of treatment
* There is uncertainty as to the optimal regimen of oxytocin to decrease the chances of caesarean section with minimal adverse effects, and there is some evidence that high dose regimens may be effective
* Administer oxytocin in hospital where the mother and baby can be closely monitored
