O efeito do banho de imersão na duração do trabalho de parto

Abstract

The objectives of this experimental, randomized, controlled trial study were to evaluate the effect of immersion baths on the length of the first stage of childbirth labor and on the frequency and length of the uterine contractions. Data were collected in a philanthropic public maternity hospital of the city of São Paulo whose month average is 1,100 births. The sample was comprised of 108 women in labor--54 in the control group and 54 in the experimental group that had immersion baths. The results showed that immersion baths did not have any influence on the length of labor and on the frequency of uterine contractions. However, the length of contractions was statistically shorter in the experimental group (experimental 41.9 versus control 44.6 min). The conclusion was that immersion baths are an alternative for the woman's comfort during labor, since it provides relief to her without interfering on the labor progression or jeopardizing the baby.

Resultados maternos e neonatais em Centro de Parto Normal peri-hospitalar na cidade de São Paulo, Brasil

“…A randomized clinical trial concluded that the immersion bath is an option for the comfort of the parturient, offering relief, without interfering in the progression of labor and without any harm to the newborn (20) . A systematic review about the immersion bath during labor, with 3,146 women, suggests that this practice reduces the use of epidural analgesia and shows no reports of adverse effects to the mother and the fetus (21) .…”

Non-pharmacological strategies on pain relief during labor: pre-testing of an instrument

“…In an experimental randomized clinical assay, performed at a philanthropic public maternity in São Paulo City, it was noticed that the immersion bath in pain relief during labor presented advantages in reducing and postponing the use of drugs in pain control, thus being a feasible option for the comfort of the parturient, without interfering in the progression of labor (13) .…”

Abordagem fisioterapêutica no pré-parto: proposta de protocolo e avaliação da dor

“…As contrações uterinas são dolorosas por causas não totalmente estabelecidas, como hipóxia do miométrio contraído, compressão de gânglios nervosos na cérvix e na parte inferior do útero pelos feixes musculares entrelaçados, estiramento cervical durante a dilatação e estiramento do peritônio subjacente ao fundo uterino 23 . Assim, observa-se a necessidade de aliviar a dor e a ansiedade da parturiente, uma vez que esses mecanismos podem prejudicar o feto e afetar a progressão fisiológica do trabalho de parto.…”

“…Assim, observa-se a necessidade de aliviar a dor e a ansiedade da parturiente, uma vez que esses mecanismos podem prejudicar o feto e afetar a progressão fisiológica do trabalho de parto. O uso de métodos não farmacológicos no alívio da dor durante o trabalho de parto tem a vantagem de reduzir e/ou postergar o uso de fármacos no controle da dor, proporcionando condições para a colaboração ativa da mulher e permitindo maior participação do acompanhante 23 .…”
