- amniotic sac may rupture
delivery of baby - ✅✅-- begins when cervix dilated
- 20 min-2 hrs
delivery of placenta - ✅✅ -- 5-10 min
- contractions again
- placenta separates from uterine wall
✅✅-analgesia, anesthesia, oxytocics
three drugs used in childbirth -
Analgesia vs Anesthesia - ✅✅-drugs that relieve pain; includes narcotics,
tranquilizers, and barbiturates
anesthesia - ✅✅-drugs that blocks pain, can be general or epidural
oxytocics - ✅✅-drugs that stimulate contractions and induce labor
postpartum psychological adjustments - ✅✅-coordinating schedules, readjusting
social relationships, bonding with baby
pros and cons of naturalistic observation - ✅✅-pro: can observe natural behavior
con: can only study what you can see
pros and cons of case study - ✅✅-pro: rich and detailed info, especially in a rare
case
con: may not be applicable to other cases
pros and cons of surveys - ✅✅-pro: a lot of info, large sample, easy
