What is the purpose of preconception care?
-to facilitate the efforts of a woman/partner to be HEALTHY before pregancy so as to have a better chanace of having a HEALTHY baby
when should preconception care begin?
3 months prior to conceiving
What is the goal of preconception care?
-to ID areas that may be unfavorable to preganancy
what do these risk factors cause duing preganancy:
Smoking? alcohol? decreased folic acid? contraceptives? Some OTC drugs?
Smoking- low birth weight, fetal nicotine addiction
alcohol-mental retard, fetal alcohole syndrome
decreased folic acid - neural tude issuses
contraceptives- decreased folic acid
Some OTC drugs- teratogens
The period of greatest enviro sensitivity and consequence risk for the developing embryo is betw/ ?
days 17 and 56 after conception (the embryonic phase)
key areas of the preconception health history are the ? (6)
- immunization status
-underlying medical issues
-reproductive heatlh
-nutrition
-lifestyle
-meds, OTC ones too
FSH is responsible for?
for maturation of the ovarian follicle
-most important during the first week of the follicular phase of the reproductive cycle
LH is responsible for?
needed for the final maturation of preovary follicles and lutenization of the ruptured follicle
-ruptures the follicle basically
estrogen is responsible for?
-helps lay down lining in the uterus
-also:
-needed to develop and mature the follicle
-increases size of uterus
-decreases after ovulation as porgesterone dominates
Progesterone is responsible for?
-allows pregnancy to be maintained by having a calming effect on the uterus (and rest of body too)
-is secreted by the corpus luteum, then the placenta
-increases ur body temp by .5- 1 degrees b4 menses
Prostaglandin is responsible for?
-helps uterine motility
-causes cervix mucus to be more helpful to sperm by way of getting into the uterus
the normal reproductive cycle consists of which two cycles?
the ovarian cycle (ovulation occure and is associated w/ the developing egg) and the endometrial cycle ( menstration occurs)
the ovarian cycle consist of 3 phases what are they?
1. the folicular phase- day one of period to ovulation, ovary grows and matures an egg (length can vary)
2. ovulation- relase of mature egg (occurs 14 days b4 menses no matter what)
3. luteal phase-begins (day 15)@ ovulation and last till next menses begins, in this phase the corpus luteum secretes increasing amount of hormone which perpares endometrial lining for implantation
mentration starts during which phase?
follicular phase (ovarian cycle) and the mentrual phase (uterine cycle)
progesterone starts being secreted during?
ovulation (b/c its secreted by the corpus luteum)
pre-embryonic phase starts? also what going on in this phase
-first 2 weeks after fertilization (w/n 12 hours)
-biggest thing going on- cellular multiplication and implantation
embryonic phase goes from ? also what going on in this phase
-from 2-8 wks
-rapid cell division and differentiation
-the fetal membranes (3 layers), amniotic fluid, and placenta form now
sufficient amounts of amniotic fluid help do what for fetus?
-help maintain constant body temp
--permit symmetric growth and development
-cushion the fetus from trauma
-allow the umbilical cord to be relatively free from compression
-and promote fetal movemetn to enhance musculoskeletal deveoplment
oligohydramnios (<500 mL of amniotic fluid @term) is associated w/ what?
uteroplacental insufficiency (insufficient blood flow to the placenta) and fetal renal abnormalities
hydramnois (>2,000 mL of amniotic fluid @term) is associated w/ what?
-maternal diabetes, neural tube deffects, chromosomal deviations, and mainly GI issuses that prevent normal swallowing of amniotic fluid by fetus
the placenta helps the baby do what? and protects the baby from what?
help protect the fetus from immune attack by mom, and removes waste products from the fetus
feuts should be moving clearly @ the latest which wk?
20th week
sex can be determined by at least which wk?
16th week
organogenic period is betw/ which weeks and is ?
@ 4-8 wks. and is the most critical period of development of congential abnormalities of "3 layers"
teratogen effect are @ greatest risk to fetus
betw/ which wks?
2-9 wks
4 causes of abnoramlities during the organogenic period are?
-genetic, enviro, multifactoral, 50-60% unknown
what are some tetatogenic agents?
any agent such as a drug, virus, or radiation that can cause development of an abnormal structure in embryo, fetus
