Among the maneuvers that are used in the second stage of labor, uterine fundal pressure is one of the most controversial and often diffuse in all over the world, generally not documented, or under reported in medical records . Many Authors affirms that a different new way to push may be of help. This maneuver was introduced by Kristeller, that in 1867 minutely described a procedure to shorten, through the application of a pressure on the uterine fundus whose intensity was quantified by a dynamometer and the duration measured in seconds, the length of the second phase of the labor. Although uterine fundal pressure maneuver was described by Kristeller as the placement of two hands on the uterine fundus and the consequential application of longitudinal steady pressure at a 30- to 45-degree angle directed toward the pelvis, with the avoidance of direct pressure toward the maternal spine, there is no clear definition of the maneuver and no indication for its use has been formally described to date.
