Sometimes amniotomy is not enough to make the contractions effective. Should that be the case, the next step then is augmentation of labor. This is only possible in a hospital. You get an IV in your hand or arm.
Prolonged labor leads to the accumulation of lactic acid in the uterus. Consequently the uterus gradually loses its abilty to respond to oxytocin stimulation. Augmentating too late is like whipping a dead horse. The contractions become disorganised, leading to fetal distress.
Timely augmentation of labor normalises labor. The laboring woman is not exhausted or demoralised. A low dose of syntocinon is often enough to get things going and the woman will have enough energy to push out her baby herself.
The baby will be monitored with CTG (EFM). That means that your room to move is somewhat limited. The length of the cord determines how far you can walk around. Some hospitals have a wireless CTG.
You do not have to lie down in bed, you can sit on the birthing ball, or stand next to the bed. Modern obstetric delivery beds can be adjusted to many positions with just one push at the button.
Depending on local agreements either your own midwife or the hospitalteam will support and monitor you. A doula stays with you any way.
