The fetal attitude refers to the position of the fetuses head in respect to the fetal spine. The longitudinal position is optimal for vaginal delivery with singleton fetus (Kirkpatrick, Garrison, & Fairbrother, 2021). The lie can be longitudinal with vertex or breech presentation, transverse with a shoulder presentation or oblique. The fetal lie refers to the longitudinal lie of the fetus in comparison to the longitudinal axis of the uterus, in other words the relationship of the spinal column of the fetus to the spinal column of the pregnant client. With breech presentation, whether complete, footling, or frank, delivery typically occurs via C-section. Most other positions may cause cephalopelvic disproportion and cause labor to become irregular and lead to surgical intervention via cesarean section (C-section). Vertex (occiput) is the optimal presentation for a vaginal delivery. A fetus descending into the pelvis and birth canal can be in a multitude of presentations and would be documented as such as the pregnant client is progressing. The possible presenting parts of the fetus are: vertex (occiput), breech (sacrum), shoulder (scapula), brow, face, or chin (mentum). The fetal presentation is the part of the fetus entering the maternal pelvic inlet first. These suture lines and fontanels can be utilized for assess for the fetal position with in the pelvic inlet during labor. As seen in the in Figure 1 the fetal head is comprised of several unfused suture lines, and fontanels allowing the fetal head to “mold” as it passes through the birth canal. The biparietal diameter measurement is the transverse distance between the the parietal bone protuberance. The biparietal diameter of a term 40 weeks gestation fetus is approximately 9.5 cm. The fetal head is the largest part of the baby. Passenger (The Fetus) – Fetal Head, Fetal Presentation, Fetal Lie, Fetal Attitude, Fetal Position Fetal Head The ability of the fetus to successfully negotiate the pelvis during labor and delivery depends on the complex interactions of three variables: uterine activity, the fetus, and the maternal pelvis” (Kirkpatrick, Garrison, & Fairbrother, 2021). “Labor and delivery are not passive processes in which uterine contractions push a rigid object through a fixed aperture.
