Fundal pressure during the second stage of labor in a tertiary obstetric center: A prospective analysis

Aim: To ascertain whether uterine fundal pressure should have a role in the management of the second stage of labor and to determine its prevalence, benefits and adverse maternal-fetal outcomes. Methods: This was a prospective observational study set in a tertiary teaching and research obstetric hospital. A total of 8097 women in labor between 37 and 42 gestational weeks with a singleton cephalic presentation were enrolled. Subjects were subdivided into two groups: fundal pressure group (n = 1974 women) and control group (n = 6123 women). The primary outcome measure was the duration of the second stage. The secondary outcome measures were maternal outcomes (immediate or delayed) and neonatal outcomes. Results: The prevalence of fundal pressure in our center was 24.38%. Fundal pressure maneuver significantly shortened the duration of the second stage among primiparous women, increased the risk of severe perineal laceration and admission to neonatal intensive care unit in comparison to the non-fundal group. Delayed maternal outcomes showed significant increase in dyspareunia and de novo stress urinary incontinence in the fundal pressure group. Conclusion: Although fundal pressure maneuver shortens the duration of the second stage of labor among primiparous women, it should not be used except when indicated, and under strict guidelines owing to its adverse maternal and fetal outcomes. © 2014 Japan Society of Obstetrics and Gynecology.
