Abstract

Introduction

The following quantitative observational study aimed to analyse the maternal and neonatal outcomes of 90 low-risk pregnant women who gave birth in water at São Bernardo Hospital.

Methods

A form containing information on the obstetric history of the parturient, the type of immersion, and the labour and birth follow-up was used by midwives to collect the data.

Background

The Apgar score (at 1 min after birth) used in this study, called Aqua Apgar, was adapted by Cornelia Enning.

Results

The mean water immersion time was 1 h and 46 min and had an influence on the duration of labour (mean 5 h and 37 min), with a statistically significant difference (P = 0.004). There was a decreased cervical dilatation time and a shorter duration of the expulsion phase. In the immersion scenario, 30% of the women did not undergo any examination to assess the length of the cervix, and 57.8% presented intact perennial areas or first-degree tears. As for neonatal outcomes, during maternal immersion, 97% maintained normal fetal heart rates (between 110 and 160 beats per minute) and Aqua Apgar was higher than 7, both in the first minute (mean of 9.4) and in the fifth minute of life (mean of 9.9).

Conclusion

These safety outcomes, based on sound scientific evidence, should increasingly support and inform clinical decisions and increase the number of waterbirths in health facilities. The results of this study align with growing evidence that suggests waterbirth is a safe delivery option and therefore should be offered to women.
