The Waterbirth Project: São Bernardo Hospital experience.

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 1min after birth) used in this study, called Aqua Apgar, was adapted by Cornelia Enning. RESULTS: The mean water immersion time was 1h and 46min and had an influence on the duration of labour (mean 5h and 37min), 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.

Perineal outcomes and its associated variables of water births versus non-water births: a cross-sectional study / Desfechos perineais e as variáveis associadas no parto na água e no parto fora da água: estudo transversal

Abstract Objectives: to describe the perineal outcomes of women who had delivered in water and out of water. Methods: a cross-sectional and quantitative study developed in a public hospital in Setúbal, Portugal. The population was of women who participated in the "Water Birth Project" in the period from 2011 to 2014, which gave birth in water and out of water. 104 women were selected according to established inclusion criteria. The groups were compared according to the following variables: demographics, obstetric information, delivery care and perineal outcomes. The data were analyzed in the Stata(r) software, with descriptive and bivariate statistics (chi-square and Fisher's test). Results: the medical records of 73 women who gave birth in water and 31 women who gave birth out of water were studied. Water deliveries were significantly associated with fewer perineal lacerations, lower rates of episiotomy, and shorter delivery time. Conclusions: the results of the study suggest that childbirth in water has a protective effect against severe third or fourth degree perineal tears, during fetal expulsion in water.

Resumo Objetivos: descrever os resultados perineais de mulheres que tiveram parto na água e fora da água. Métodos: estudo transversal e quantitativo desenvolvido em um hospital público de Setúbal, Portugal. A população foi de mulheres que participaram do "Projeto Parto na Água", no período de 2011 a 2014, que deram à luz na água e fora da água. Foram selecionadas para o estudo 104 mulheres de acordo com os critérios de inclusão estabelecidos. Os grupos foram comparados de acordo com as seguintes variáveis: demografia, informação obstétrica, assistência ao parto e resultados perineais. Os dados foram analisados no software Stata(r), com estatísitica descritiva e bivariada (qui-quadrado e teste de Fisher). Resultados: foram estudados os prontuários de 73 mulheres que deram à luz na água e 31 mulheres que deram à luz fora da água. Os partos na água foram significativamente associados a menos lacerações perineais, menores taxas de episiotomia e menor tempo de parto. Conclusão: os resultados do estudo sugerem que o parto na água tem um efeito protetor contra lacerações perineais severas de terceiro ou de quarto grau durante a expulsão fetal na água.
