Are all Kristeller maneuver’s forbidden?

ABSTRACT
Objective. Kristeller maneuver was first described by Samuel Kristeller in Berlin in 1867, in literature named “Fundal pressure” (FP), because the original maneuver can be performed in the second stage of labor.
The aim of the narrative review is to point out that the FP maneuver isn’t prohibited by all the authors even though there are conflicting opinions in clinical practice and in literature.
Materials and methods. A literature search of the last 35 years was performed on PUBMED, SCOPUS, EMBASE, MEDLINE, GOOGLE SCHOLAR, with the aim of clarifying the real advantages or disadvantages of this maneuver and at the same time, to identify in which situations  it can be done safely due to the lack in literature, taking into account that more complications about maternal and fetal injuries related to FP are not reported in literature, for medical legal problems.
Results. These findings highlight the importance of obtaining informed consent from women before administering FP to ensure the protection of women’s autonomy during the birthing process. The impact on the maternal perineum remains uncertain based on our findings.
Through a regression analysis model, author determined that only the duration of the second stage, neonatal weight, and the use of episiotomies were significantly associated with the Kristeller maneuver.
Conclusions. It is authors’ belief that this maneuver should be reported into the international Guidelines with the aim of having strict but clear indication for its application and reducing future legal litigations.
