Brief summary
The purpose of this study is to determine whether birth on a birthing seat will effect numbers of instrumentally assisted vaginal births, vaginal traumas, blood loss,use of artificial oxytocin for labour augmentation and fetal outcomes.
Interventions
DEVICEBirthRite birthing seat
Randomization takes place on admission to the labor ward when the participants are in active labor.Participants in this arm were to sit on the seat for 20 minute periods.After these 20 minutes, the participant should stand and mobilize during two to three contractions, before resuming the birth seat position. If progress of the descent of the fetal head was obvious the participant was not asked to mobilize.
