Passenger
fetus
The fetal skull consists of 3 major parts...
face, cranium, and vault
- vault consists of 2 frontal bones, 2 parietal bones, and the occipital
bones (these are not infused)
Sutures
membranous joints that unite the cranial bones, allow for molding
- frontal suture between frontal bones
- sagittal suture between parietal bones divides the skull in halves,
connect 2 fontanelles
- coronal suture between frontal and parietal
- lambdoidal suture located between parietal and occipital
Attitude
the relation of the fetal body parts to one another
- fetal posture is generally flexed
Lie
relationship of the spinal column of the fetus to the spinal column of the
mother
- longitudinal or transverse
,Presentation
- determined by fetal lie
- refers to the body part of the fetus that enters the pelvis first
- cephalic
- face
- brow
- breech
- shoulder
Descent
assesses relationship of pelvis and presenting part
- ballotable: floating or freely moveable above pelvic inlet
- engagement: occurs when the largest diameter of the presenting part
passes through the pelvic inlet
Station
the relationship of the presenting part to an imaginary line drawn
between the ischial spines of the pelvis
Position of Fetus
- left or right side of pelvis
- anterior or posterior of pelvis
- bony part presenting
- occiput (cephalic presentation)
- mentum (chin, face presentation)
, - sacrum (breech)
- acromium process (shoulder presentation)
Ways to assess position
- Leopold maneuvers
- vaginal exam
- auscultation of fetal heart tones
Passage
- birth canal
- consists of the pelvic inlet, mid pelvis, and outlet
- the size and type affects the labor and delivery process and outcome
Gynecoid
- adequate pelvic outlet
- round, slightly oval, 50% of women
- most favorable for delivery
Android
- normal male pelvis
- heart shaped, 20% of women
- not favorable for delivery
Anthropoid
- 25% of women, narrow arch
- favorable for labor
