Abstract

Obstetric forceps are used as an instrumental delivery method when physiological childbirth fails to progress. The technique comprises the insertion of two stainless steel blades in the vagina that are subsequently coupled to make firm contact with the fetal head. In this paper, we assessed the effect of symmetric against asymmetric placement of the blades around the fetal head. Assessment was facilitated in-silico by creating mesh models of the fetal head and forceps and conducting implicit dynamic finite element analyses using the Hilber-Hughes-Taylor integration method, with imposed contact constraints between the virtual head and forceps. We observed that asymmetric forceps blade placement causes increased local deformations and strains that may potentially be harmful to the fetus. We conclude that forceps traction should not be applied when blades are asymmetrically placed around the fetal head.
