SCARABOTTO, Leila Barreto and RIESCO, Maria Luiza Gonzalez. Factors related to perineal trauma in normal births in nulliparous. Rev. esc. enferm. USP [online]. 2006, vol.40, n.3, pp. 389-395. ISSN 1980-220X. http://dx.doi.org/10.1590/S0080-62342006000300011.
Many studies have been undertaken with the purpose of contributing towards the prevention of perineal trauma in normal birth. The objective of this study was to relate height of the perineum, duration of the second stage of labor, variation of the position of the head detaching, kind of effort, presence of the umbilical cord around the babies' neck, birth weight and vulva's ardor to urinate with the occurrence of perineal laceration. The study was undertaken in 2003 at the Normal Birth Center of the Amparo Maternal, with a sample consisting of 67 women in labor without previous vaginal births. The results demonstrated that there were no significant statistical differences between the variables verified.
