  • Administration of oxytocin for augmentation of labor [ Time Frame: During labor and birth up to 36 hours postpartum ]
  • Postpartum blood loss [ Time Frame: Up to 24 hours after birth ]
    Blood loss postpartum is weighed and measured and maternal hemoglobin levels are registered.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Supportive Care
  • Instrumental Vaginal Births
  • Oxytocin Augmentation for Labor
  • Maternal Blood Loss
  • Perineal Outcomes
  • Fetal Outcomes
Device: BirthRite 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.
Other Name: BirthRite® birthing seat
  • Experimental: Birth seat group
    Randomized to birth on a midwife designed birth seat
    Intervention: Device: BirthRite birthing seat
  • No Intervention: Non-birth seat group
    Randomized to birth in any other position except on the midwife designed birth seat.
