Takeaway

  • Women delivering in a "sensory delivery room" had a slightly lower risk of cesarean delivery (CD) compared with women in a standard delivery room.

Why this matters

  • Most primary births naturally commence at night or in the early morning.
  • This study raises an interesting idea that labor can be influenced by alteration in light or time of day.

Key results

  • Rate of CD in sensory delivery room was lower compared with a standard delivery room:
    • 6.4% vs 10.7%;
    • aOR, 0.44 (95% CI, 0.22-0.87).
  • Indications for CD (standard vs sensory) included:
    • asphyxia: 21% vs 33%;
    • inefficient uterine action: 21% vs 28%;
    • cephalopelvic disproportion: 47% vs 39%; and
    • failed vacuum: 9% vs 0%.
  • Increased risk of postpartum hemorrhage >1000 mL in the sensory group:
    • aOR, 2.01 (95% CI, 1.07-4.09).
  • Lower need for oxytocin in the sensory group:
    • aOR, 0.71 (95% CI, 0.50-1.03).

Study design

  • Retrospective observational cohort study.
  • Nulliparous women in spontaneous labor were assigned to a sensory delivery room (n=313) or a standard delivery room (n=476) based on preference and availability.
  • Sensory delivery rooms offer programmable calming lights, images, and sound effects.
  • Funding: Region Zealand in Denmark.

Limitations

  • Participants selected type of birthing room.
