Growth changes in uterus during pregnancy
Nonpregnant uterus
Weight: 70g/2.5oz
Capacity: 10ml
Term uterus
Weight: 1100-1200g/2.4-2.6lb
Capacity: 5L
Uterine growth occurs as a result of ?
Hyperplasia in early pregnancy caused by estrogen and growth factors
Hypertrophy in later pregnancy due to muscle fibers stretch in all directions to accommodate growth
The fundus is normally located at the umbilicus at what gestational age
20 weeks
The fundus reaches its highest level when
The xiphoid process At 36 weeks gestation
Lightening
Descent of the fetal head into the pelvic cavity
Presumptive indications
Are subjective changes that are experienced and reported by the woman
These changes are the least reliable indicators of pregnancy because they can be caused by conditions other than pregnancy
Examples of presumptive indications
Amenorrhea Nausea and vomiting Fatigue Urinary frequency Breast and skin changes Quickening
Quickening
The first movements of the fetus felt by the mother
Probable indications
Are objective findings that can be documented by an examiner
Primarily related to physical changes in the reproductive organs
Examples of probable indications
Abdominal enlargement Goodell sign Hegar sign Ballottement Braxton hicks contractions Palpation of fetal outline Uterine souffle Positive pregnancy test
Goodell sign
Softening of the cervix due to pelvic vasocongestion
Hegar sign
Softening of the lower uterine segment that allows it to be easily compressed at 6 to 8 weeks of pregnancy
Ballottement
When the cervix is tapped, the fetus floats upward in the amniotic fluid. A rebound is felt by the examiner when the fetus falls back
Near mid pregnancy
Uterine soufflé
In late pregnancy - a soft, blowing sound may be auscultated over the uterus
This is the sound of blood circulating through the dilated uterine vessels and it corresponds to the maternal pulse
Funic soufflé
The soft, whistling sound heard over the umbilical cord and corresponds to the fetal heart rate
Examples Positive indications
Only 3 signs accepted as positive confirmation of pregnancy :
Auscultation of fetal heart , fetal movement detected by an examiner and visualization of the embryo or fetus
Chadwick sign
Bluish purple discoloration of the cervix, vagina and labia during pregnancy as a result of increased vascular congestion
Supine hypotension syndrome
When the pregnant woman is in the supine position, the weight of the uterus partially occludes the vena cava and the aorta.
Laying on your LEFT side corrects it
Progesterone and respiratory changes
Relaxes smooth muscle in the respiratory tract
Heightened awareness of the need to breathe
Estrogen and respiratory changes
Increased vascularity of mucous membranes
Causes increased nasal congestion and epistaxis
Relaxin and respiratory changes
Causes relaxation of the ligaments around the ribs
Relaxes skeletal muscle and cartilage
Ovaries and reproductive system changes
Ovulation ceases due to increased levels of estrogen and progesterone inhibiting the release of FSH and LH
Ptyalism
Excessive salivation
Progesterone and gi changes
Relaxes smooth muscle , which decreases gi motility , which can lead to constipation
Angiomas
Tiny red elevations branching in all directions
Look like red moles to me
Diastasis recti
Separation of the rectus abdominal muscles
HCG
Prevents deterioration of the corpus luteum so that it can continue producing estrogen and progesterone until the placenta is sufficiently developed and takes over
Estrogen
GROWTH
stimulates uterine growth
Increased vascularity
Prepares breast for lactation
Hyperpigmentation
Progesterone
MAINTENANCE
maintains endometrial lining / prevents menstruation
Relaxes smooth muscle
Increased respiratory sensitivity to CO2 (urge to breathe)
Suppress immune response - prevents rejection of the fetus
HPL
Human placental lactogen
Primary function to increase the availability of glucose for the fetus
What is the recommended weight gain during pregnancy
11.5 to 16 kg (25-35 lbs)
Pattern of weight gain
First trimester: gain 0.5 to 2 kg (1.1-4.4 lb)
0.35 to 0.5 kg (0.8-1lb) per week thereafter
Calorie intake during each trimester
First: no additional calories needed
Second: increase by 340 per day
Third: increase by 452 per day
Most common simple carbohydrate
Sucrose (table sugar)
Complex carbohydrates
Present in starches such as cereal, pasta and potatoes - supply vitamins, minerals and fiber
Fiber
Nondigestible product of plant foods , important source of bulk in the diet
Stimulates peristalsis, prevents constipation and slows gastric emptying causing a sensation of fullness
Fats help in the formation of
Fetal nerve, brain and visual development and visual function
Examples of Food sources for omega 3 fatty acids
Salmon, flaxseeds and oil, soybeans, walnuts
RDA of protein during pregnancy
Should be increased to 71 g daily
Compared to 46g for non pregnant females
Examples of sources of protein
Fish, egg, beans , peas , nuts, soybeans
Tofu from soybeans is a good source of protein , calcium and iron
Fat soluble vitamins
K A D E
Water soluble vitamins
B C
Women during child bearing age should consume how much folic acid
400 micrograms daily
Once pregnancy occurs should increase to 600 mcg daily
Folic acid
Deficiency results in neural tube defects, which can lead to spina bifida or skull/brain malformations
Also cleft lip, cleft palate, some heart defects, premature birth, LBW, abruptio placentae
What is the goal of iron consumption during pregnancy
To prevent iron-deficiency anemia
For best results iron should be taken with
Water or a source of vitamin c like orange juice
** don’t take with coffee, tea or milk **
Calcium is important in
Mineralization of fetal bones and teeth
Calcium is best absorbed when taken with
Vitamin d (eggs, cereal) to increase absorption
PICA
Eating substances not usually considered part of a normal diet
Ex: ice, clay or dirt and laundry starch
A multifetal pregnancy should gain how much
Woman with twins should gain 5.5 to 9kg (12-19lbs) more than a woman with a single fetus
Or
17 to 25kg (37-54lbs)
