    • 5x the risk during peurperium (approx 6-8wks postpartum)
  23. Endocrine changes during pregnancy
    • Euthryroid--
    • -gland enlargement
    • -placental Hcg-->stimulation of T4
    • Estrogen-->hepatic synthesis of TBG-->increased levels of total T3 and T4
    • Thyroid is working normally, but other hormones are affecting serum levels
  24. Description of the fetus during labor
    • Stations--0=presenting part is level with ischial spine
    • (-) values are superior to ischial spines
    • (+) values are inferior to ischial spines
  25. Placenta Previa defined
