Preliminary Signs of Labor
Lightening
Slight weight loss
Excess energy
Backache
Ripening of the cervix
Signs of TRUE Labor
Rupture of membranes
Show
Contractions
True Labor
- Timing of contractions regular
- Radiating contraction pain
- Unable to relieve contraction pain with activity
- Exam changes present
Fake Labor
- Fails to cuase changes to cervix and baby’s position
- Activity diminishes contractions
- Keep feeling contractions above belly button (they don’t radiate from back to abdomen)
- Erratic timing of contractions

e. and fetal lie.
With a big baby, you have a ____________ chance of a difficult vaginal delivery. You may also have an increased risk of _______________________________________________
greater; preterm birth, perineal tearing, and blood loss
Portion of the body of the fetus that is foremost within the birth canal or in closest proximity to it.
Presentation
The most common presentation
Cephalic
Types of Cephalic Presentation
VERTEX/OCCIPUT
BROW
MILITARY/SINCIPUT
FACE
BUTTOCKS FIRST
BREECH
Types of Breech Presentation
Frank
Complete
Footling
Fetus is in a _____________________, or the arm, back, abdomen, or side could present.
transverse lie
shoulder or acromion is presenting into the pelvic inlet
shoulder presentation
bisacromial dimatere (11 cm) presents
shoulder presentation
fetal hand or foot prolapses alongside the presenting vertex or breech
Compound presentation
relationship of the chosen portion of the fetal presenting part in reference to one of the 4 quadrants or transverse diameter of birth canal
Position
the relationship of the fetal body parts to one another
attitude
Fetal Position
Occiput (cephalic/vertex position)
Mentum or chin (face presentation)
Sacrum (breech presentation)
Acromion or scapula (shoulder presentation)
Feta lspine is parallel to the mother’s spine.
longitudinal or vertical
Fetal spine is at a right angle, or perpendicular, to the mother’s spine
transverse or horizontal
this position is very rare and occurs in fewer than 5% of pregnancies
oblique
PASSENGER ASSESSMENT
Leopold’s maneuvers
Vaginal examination
The mother’s rigid bony pelvis and the soft tissues of the cervix, pelvic floor, vagina, and introitus (external opening to the vagina)
PASSAGE/ PASSAGEWAY
most common, 55%, inlet transverse diameter is wider than the antero-posterior diameter
Gynaecoid
20% of women, heart shaped inlet, funnel-shaped cavity, narrow inlet
Android
20% women, oval-shaped inlet, maximam diameter AP with a long and narrow cavity
Anthropoid
5% of women, flattened transversely oval, shallow cavity and spacious outlet
Platypoid/Platypelloid
Forces of labor acting in concert to expel the fetus and placenta
Power
