Cross-sectional study, developed with data from the research "Born in Belo Horizonte Labor and birth survey, "conducted with 577 women who had their children via vaginal birth. In order to verify the magnitude of the association between episiotomy and its possible determinants, logistic regression models were constructed to estimate the odds ratio. Episiotomy was performed in 26.34% of women, and 59.21% knew they had been subjected to it. We observed that younger women, primiparous women, women assisted by a professional other than the obstetric nurse and women who had their babies in a private hospital have an increased chance of being submitted to this procedure. Considering the rates of episiotomy, this study highlights the need for the absolute contraindication to indiscriminate performing it.

To evaluate effectiveness of using educational intervention serial album to positioning pregnant women for spinal anesthesia. Randomized clinical trial with 90 women casually assigned to control (CG) and intervention group (IG), in a maternity hospital located in Northeast region of Brazil. The primary endpoint was "achieve correct positioning to perform spinal anesthesia"; and secondary, "how number of spinal cord puncture attempts". Effectiveness was verified using the chi-square test, Fisher's exact test and likelihood ratio. The positioning was correct in 37 women in each group. There was an association between women in control group remaining still, relaxing shoulders and flexing the spine; and women in intervention group should remain still and relax the shoulders; furthermore there was a statistical association achieved by correct positioning and the number of attempts to access the lumbar puncture.
