Fetal Malpresentation Flashcards
What is the difference between malpresentation and malposition
Malpresentation: When any fetal part other than the occiput (the back of the fetal head) is the presenting part.
Malposition:
Types of malpresentations:
Breech
Cephalic presentation with deflexion attitudes
compound presentation
Transverse lie
Describe breech
Fetal buttocks, knees, or feet are presenting
describe cephalic presentations with deflexion attitudes
fetal head is presenting but the baby’s head is extended (tilt back). This means that the top of the baby’s head or the face is presenting.
Describe compound presentation
The baby’s hand or arm is in front of the head
Types of breech presentations
complete breech
frank breech
footling breech
Presentations if persistent, is an indication for a cesarean delivery
Transverse lie
Mentum anterior presentation
What is a mentum anterior presentation
Abnormal form of cephalic presentation when the presenting part is the mentum(chin)
Hyperextension of the neck and the occiput touching the fetal back
Describe frank breech
when the baby’s leg are folded flat up against the head and his bottom is closest to the birth canal
Flexed at the hips and extended at the knees
Describe complete breech
when both of the baby’s knees are bent and his feet and bottom are closest to the birth canal
Describe footling breech
when one or both feet are presenting
Describe transverse lie
the long axis of the baby’s body is diagonal or crosswise (rather than longitudinal or aligned with) the mother’s body.
This often means that the baby’s shoulder is presenting.
Factors that increases success in External cephalic version
Parity
Transverse and oblique presentations
Amniotic fluid volume
Location of placenta
Maternal weight
