  1. Post term Pregnancy: def, effects
    • Def: when pregnancy exceeds 42 completed weeks from the 1st day of the LMP
    • Effects: Placental aging, decrease AFV (amniotic fluid volume); Problems: asphyxia, meconium aspiration, RDS, put around 1/2lb per week after
  2. Post term pregnancy: risk factors, s/s
    • Risk factors: pervious posterm delivery, estrogen deficiency, decrease placental sulfatase (which produces estrogen), decrease adrenal coritcal function.
    • S/S: diminished fetal growth, oligohydramnios (decrease fluid), meconium-stained fluid
  3. Post mature newborn:
    subcutaneous fat loss, long fingernails, wrinkled peeling skin, alert facies, absence of lanugo and vernix
  4. Management of post term pregnancy:
    • Fetal kick counts
    • side-lying position
    • good hydration
    • NST and CST
    • BPP weekly
    • Weekly cervical checks
  5. Complications of post term pregnancy:
    • Fetal acidosis
    • Oligohydramnios (decrease fluid)
    • meconium aspiration
    • fetal wasting
    • neonatal mortality
    • Neonatal hypoglycemia
    • Neonatal polycythemia (hyperbilirubinemia)
    • Neonatal impaired thermoregulation
  6. Induction of labor: def, augmentation of labor
    • Def: deliberate initiation of labor, prior to the onset of spontaneous contractions
    • Augmentation of labor: stimulation of uterine contractions after labor has started but is not progressing satisfactorily
  7. Induction of labor: mechanical vs. physiologic vs. chemical
    • Mechanical: amniotomy (can scratch baby's head if decreased fluids)
    • Physiologic: ambulation, maternal position change, nipple stimulation
    • Chemical: Prostaglandins, misoprostel, oxytocin
  8. Indications for Induction:
    • Maternal problems: Diabetes, PIH, PROM, chorioamnionitis, abruption, postdates
    • Fetal problems: fetal hemolytic disease, IUGR, low BPP, intrauterine death...
  9. Readiness for Induction:
    • Capability of delivering vaginally: r/o structural abnormalities, previous GYN/abd surgeries
    • Fetal maturity: assess L/S ratio (tests if lungs are mature)
    • Cervical readiness/fetal station: Bishops score
  10. Bishop Pelvic scoring system:
    • Max # is 13
    • 0-4 is unfavorable
    • 5-8 is questionable
    • >8 is successful induction

    • Herbal remedies
    • Stripping the membranes (can break water)
  12. Methods of cervical ripening and labor induction: pharmalogical
    • Prostaglandin gel (strongly increases contractions; contraindication is asthma and pitocin)
    • Cervidil: like a flat tampon, releases over 12 hrs, you can take it out. *Both these forms have suppository's, in larger doses, are are used for aborting fetus bc of STRONG DOSE!!!!!!
    • Misoprostel (Cytotec): 25ug tab in posterior vag fornix, some oral, NOT fda approved!
    • Mechanical means: laminaria (seaweed in cervix), foley cath in cervix
