NCT05175599

Brief Summary

This study aims to explore outcomes of waterbirth in comparison to conventional land birth for low-risk healthy women and neonates in a hospital setting in Milwaukee, WI. This study hypothesizes that women who labor and birth in water will use less pain medication, have a shorter labor, will be more likely to initiate breastfeeding prior to discharge, will not experience more negative outcomes, and will experience greater satisfaction than women who labor and birth on land.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Number of Women Using Intravenous Narcotic Analgesia and Epidural Anesthesia

    The number of women in the waterbirth cohort who use IV narcotic and epidural anesthesia compared with the land birth cohort.

    Time of admission to birth of the baby

Secondary Outcomes (7)

  • Median Time of Labor Duration

    Time of labor onset to time of birth

  • United States Birth Satisfaction Scale-Revised (US-BSS-R) Score

    Up to 72 hours post delivery

  • Number of Reported Maternal Adverse Outcomes

    During labor and birth through the immediate postpartum hospital admission (24-48 hours after the birth)

  • Number of Patients Breastfeeding

    Measured from birth (immediate) through discharge from hospital (24-48 hours)

  • Number of Neonatal Adverse Outcomes

    Immediately after the birth until the time of the postpartum visit (usually 4 to 6 weeks of life)

  • +2 more secondary outcomes

Study Arms (2)

Land Birth

NO INTERVENTION

Women in the land birth group will labor and give birth according to standard of care procedures.

Water Birth

EXPERIMENTAL

Women in the water birth group will give birth in the water. During the first stage of labor, women may enter or leave the water at any point.

Other: Water Birth

Interventions

The water birth group will use a tub of a water to labor and give birth.
