Passenger-Lie
|
the relationship to the maternal longitudinal axis (spine) to the fetal longitudinal axis (spine).
|
|
|
Lie - (Transverse)-
|
fetal long axis horizontal-not accomodate vaginal birth. Shoulder is presenting- C-section needed.
|
|
|
Lie- (Parallel or longitudinal)
|
fetal long axis is parallel to maternal long axis. Cephalic or breech presentation.
|
|
|
Passenger - Attitude
|
relationship of fetal body parts to one another.
|
|
|
Attitude - Fetal Flexion
|
chin flexed to chest, extremities flexed into torso. (normal). Abnormal- can cause longer labor/c-section.
|
|
|
Passenger - Presentation
|
the part of the fetus that is entering the pelvic inlet 1st.
|
|
|
Presentation - What are the diff. parts that can enter inlet first?
|
back of the head (occiput), chin (mentum), shoulder (scapula), or breech (sacrum).
|
|
|
What are the different kinds of presentation?
|
brow, face, breech,complete, frank, footling, shoulder.
|
|
|
Breech presentation
|
butt enters 1st, usually when abnormalities of the uterus and pelvis or preterm fetus.
|
|
|
Fetal Position
|
relationship of presenting part of the fetus in reference to its directional position as it relates t o 1 of the 4 maternal quadrants.
|
|
|
Fetal position labeling
|
1. 1st letter- R or L side of maternal pelvis
2. 2nd letter- presenting part of fetus. 3. 3rd letter- Anterior, posterior, or transverse part of pelvis. |
|
|
station
|
measurement of fetal descent in cm w/ station 0 being at level of an imaginary line at level of the ischial spines: - stations above and + is below. They use 2 fingers to tell.
|
|
|
engagement
|
the presenting part occurs when largest diameter of presenting part reaches or passes through pelvic inlet.
|
|
|
Engagement
|
determined by vaginal examination. Occurs diff. times for primi's and multi's. Multi's might be ballotable.
|
|
|
Why might one do a digital vaginal exam during labor?
|
To assess for cervical dilation/effacement, fetal station, fetal position-presenting part-lie, and ROM-intact or ruptured?
|
|
|
Positional changes of the fetus during Labor
|
Descent, flexion, internal rotation, extension, restitution, external rotation, expulsion.
