[The effect of immersion baths on the length of childbirth labor]

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.
