Study Notes
Factors Affecting Labor & Delivery
-
Passage:
- Pelvic measurements are important
- Diagonal Conjugate (inlet diameter)
- Transverse Diameter (outlet)
- Posterior fontanelle (Lambda) is diamond-shaped, at junction of coronal and sagittal sutures.
- Posterior fontanelle (Lambda) is triangular, at junction of lambdoidal and sagittal sutures.
- Pelvic measurements are important
-
Passenger:
- Fetal skull: 8 bones (4 superior: frontal, 2 parietal, occipital; + 4 others: sphenoid, ethmoid, 2 temporal)
- Vertex: space between fontanelles
- Sinciput: area over frontal bone
- Occipital: area over occipital bone
- Fetal skull diameters:
- Suboccipitobregmatic: 9.5 cm (inferior occiput to anterior fontanelle)
- Occipitofrontal: 12 cm (from chin to occipital prominence)
- Occipitomental: 13.5 cm (widest AP diameter from chin to posterior fontanelle)
- Molding: change in fetal skull shape due to sutures overlapping
- Can decrease biparietal diameter by 1 cm
- Recorded as 0-3, with increasing overlapping
- Fontanelles: membrane-covered spaces at suture junctions
- Anterior fontanelle (Bregma)
- Fetal skull: 8 bones (4 superior: frontal, 2 parietal, occipital; + 4 others: sphenoid, ethmoid, 2 temporal)
-
Fetal Presentation and Position:
- Fetal attitude: degree of flexion (full, moderate, partial, poor)
- Fetal lie: relationship of fetal long axis to maternal long axis (vertical or horizontal)
Engagement
- Settling of presenting part into pelvis.
- Biparietal diameter or intertrochanteric diameter passes the pelvic brim.
Causes of Non-engagement (Primiparas)
- Abnormal fetal presentation or position
- Abnormality of the fetal head
Types of Fetal Presentation
-
Cephalic (most common, 95%)
- Vertex: optimal
- Brow: head moderately extended
- Face: head hyperextended
-
Breech:
- Complete: hips and knees flexed.
- Frank: buttocks and legs extended.
- Footling: one or both feet present first.
Fetal Positions
- Relationship of presenting part to pelvic quadrants (e.g., LOA, ROA)
- LOA: most common, presenting part towards left side of pelvis
Mechanisms of Labor (Cardinal Movements)
- Descent
- Flexion
- Internal Rotation
- Extension
- External Rotation (Restitution)
- Expulsion
Signs of Labor
-
True labor contractions:
- Regular, becoming stronger over time.
- Begin in lower back and move forward.
- Increase in frequency and intensity.
- Not relieved by rest.
- Progressive cervical dilation.
-
False labor contractions:
- Irregular and intermittent.
- Located primarily in the abdomen.
- Do not increase in intensity or frequency.
- May stop with walking or rest.
-
Show (bloody show): mucus plug expelled with blood.
-
Rupture of membranes: expulsion of fluid.
Importance of Partograph
- Prevention of prolonged labor
- Improvement in maternal and neonatal outcomes
Stages of Labor
-
Stage 1:
- Latent Phase / Preparatory Phase: regular contractions start, cervix dilates (0-3cm), effacement begins.
- Active Phase: rapid cervical dilation (4-7 cm); strong contractions.
- Transition Phase: maximum cervical dilation (8-10 cm)
-
Stage 2: (onset from full cervical dilatation to birth of infant).
-
Stage 3: (from birth of infant to expulsion of placenta).
-
Stage 4: postpartum period
Danger Signs of Labor & Delivery
- Fetal:
- High or low fetal heart rate
- Meconium staining
- Fetal acidosis (pH <7.2)
- Maternal:
- Rising BP (PIH)
- Abnormal pulse
- Inadequate contractions
- Abnormal lower abdominal contour
- Prolapse of cord
Care During Labor & Delivery
- First Stage: pain relief, void, respect contractions, position changes, bladder care.
- Second Stage: support client's pushing efforts and position, monitor FHR, support birth positions, perineal care following delivery.
- Third Stage: delivery of placenta, positioning for uterine contractions, observe for bleeding.
Placenta Assessment
- Membranes: complete, ragged.
- Maternal side: characteristics, cotyledons.
- Fetal side: umbilical cord (insertion), blood vessels.
Postpartum Period
- Retrogressing changes: uterus returns to normal size, hormonal fluctuations, circulation changes.
- Lactation: primary engagement, breast changes.
