Term
What is hCG's (Human Chorionic Gonadotrophin) function in pregnancy?
Definition
-it is secreted from from the trophoblast
-prevents degeneration of the corpus luteum and stiumlates it to secrete oestrogen and progesterone until placenta takes over around 12 wks
-linked to changes in smell, taste and saliva
-may be responsible for nausea in 1st trimester
-has an immonosuppressant effect thereby preventing the woman from rejecting her foetus and placenta
-present in the bloodstream 7-10 days after conception, and in the urine 26-28 days
Term
Trophoblast
Definition
the flattened outer cells of the blastocyst that eventually forms the placenta
Term
Corpus luteum
Definition
A hormone-secreting structure that develops in an ovary after an ovum has been discharged but degenerates after a few days unless pregnancy has begun
Term
Hormonal adaptation
Definition
-hCG (Human Chorionic Gonadotrophin)
-hPL - Human Placental Lactogen
-Oestrogen
-Progesterone
Term
Human Placental Lactogen (hPL)
Definition
-reduces maternal usage of glucose by reducing the response of maternal cells to insulin, thereby making more available to the foetus
-mobilises maternal lipid stores leaving the glucose for foetal uptake
-accelerates maternal transfer of amino acids to the foetus
Term
Oestrogen
Definition
-stimulates growth of tissues - uterus, breasts
-causes swelling and softening of connective tissue
-increases sensitivity of the uterus to progesterone
-increases sensitivity of maternal resp system to Co2
-effects lead to some water retention, oedema, pelvic relaxation of ligaments and joints
Term
Progesterone
Definition
-lowers smooth muscle excitability
-has a role in implantation and helps to suppress maternal immunological response
-responsible for oesophageal reflux, N/V, UTI, Varicose veins, Haemorrhoids, Postural Hypotension and Body temp increase by 0.5-1 degree
Term
Respiratory adaptation during pregnancy
Definition
-increased basal metabolic rate
-progesterone and oestrogen work to increase sensitivity of the resp centre to CO2 resulting in mild hyperventilation
-increases oxygen consumption - 20%
-Flared ribs and raised the position of the diaphragm caused by relaxing of the muscles and cartilage of the thorax
-change from abdominal to thoracic breathing
-sleep disordered, snoring
Term
Skeletal adaptation during pregnancy
Definition
-progesterone relaxes ligaments and muscles thereby increasing pelvic capacity, pelvis is widened and the coccyx is able to be pushed out of the way during labour
-Lordosis of the spinal column (causes back pain)
Term
Lordisis
Definition
exaggerated forward curvature of the lumbar and cervical regions of the spinal column
Term
Renal adaptation during pregnancy
Definition
-increased metabolic wastes from the maternal and foetal metabolism
-glomerular filtration rate increased by 40-50% in 1st Trimester due to increase in renal blood flow
-mild glycosuria, proteinuria and increased creatinine clearance - resulting from normal changes in renal function
-relaxation of smooth muscle by progesterone affecting the bladder and ureters increases the risk of urine stasis and UTI's
-sodium retention
-increased extracellular volume
-decreased bladder tone
-bladder capacity doubles
Term
Glomerular Filtration
Definition
-filtration of fluid through the kidneys
-it allows water, solutes and small protein molecules to pass through, but blood cells and larger protein molecules are prevented from passing through.
-in pregnancy the glomerular size increases the the number of cells stay the same...therefore, larger molecules can pass through, thus the incidence of proteinuria
Term
Glomerular Filtration
Definition
-filtration of fluid through the kidneys
-it allows water, solutes and small protein molecules to pass through, but blood cells and larger protein molecules are prevented from passing through.
-in pregnancy the glomerular size increases the the number of cells stay the same...therefore, larger molecules can pass through, thus the incidence of proteinuria
Term
Cardiovascular adaptation during pregnancy
Definition
-increase in blood volume 30-50%
-Haemo dilution causes a drop in Hb (Haemoglobin/Iron)115-160d/l (non pregnant) to 100-150g/l (pregnant)
-WCC increases and iron stores can also fall
-BP same or drops slightly
-relaxation of walls of the veins increases their capacity by as much as a litre
-Skin and mucous membranes receive up to 70% increase in blood flow by the 36th week
-Supine posi causes uterus to compress vena cava and decrease venous return
-effects: heat intolerance, sweating, nasal congestion
Term
Integumentary adaptation in pregnancy
Definition
-melanocyte-stimulating hormone increases which causes deeper skin pigmentation that can lead to: chloasma (irregular brownish or blackish spots especially on the face), Linea nigra (pigmented line on abdomen from navel to pubis) and areola darkening and toughening
Term
Reproductive adaptation in pregnancy

Cause & Treatment for Morning Sickness
Definition
Changes is taste and smell can contribute & more severe in women with higher hCG levels. Also, iron supplements can increase nausea.
Help: Eat small meals often, avoid greasy & spicy foods, drink small amounts of fluids often, mandarin oil, VitB6, accupressure/puncture, ginger tea & glace fruit, eat watermelon, carb snacks at bedtime & before rising.
Term
Cause & treatment for Urinary frequency
Definition
Increased circulating volume, increased GFR, increased pressure on the bladder from the uterus in 1st & 3rd trimester
Help: Burning or pain needs to be ruled out for UTI & vaginal infections, maintain fluid intake
Term
Cause & treatment for Increased Perspiration
Definition
Increases in endocrine glands on skin, possible because of increased thyroid activity, increased dilation of the blood vessels in the skin.
Help: reassure the this is normal, bathing, loose fitting clothing of absorbent material, control room temperature
Term
Cause & Tx for Dizziness & Syncope
Definition
Growing uterus causes compression of lower extremities & pelvic veins causing venous pooling, warm weather makes it worse, hypoglycaemia secondary to n&v.
Help: calf exercises & long support stockings to combat venous pooling; use left lateral tilt position for correcting hypotension
Term
Cause & Tx for Oedema
Definition
Slowed venous return caused by uterine pressure on Vena Cava in 3rd tri, increased circulating blood volume.
Help: avoid sitting & standing for long periods of time, daily leg exercises, support stockings, loose fitting waistbands, leg elevation & rest
Term
Cause & Tx Varicose Veins
Definition
Relaxation of smooth muscle, increased venous pressure in pelvis & lower extremities, found in legs & vulva, leads to leg fatigue & painful night leg cramps.
Help: rest & elevation, elastic stockings
Term
Cause & Tx Lower back ache
Definition
Altered center of gravity, stretched abdo muscles, lumbar lordosis, 3rd tri joints & ligaments become more lax.
Help: avoid excessive weight gain, improve posture, proper bending with straight back, sleeping on firm mattress, local heat, massage
Term
Oedema Classifications
Definition
1+ slight pitting, disappears rapidly (2 mm)
2+ deeper pit, disappears in 10-15 secs (4mm)
3+ Pit is noticeably deep and may last more than a minute. The extremity looks fuller & swollen (6mm)
4+ the pit is very deep, lasts 2-5mins, and the extremity is grossly distorted (8mm)
Term
Cause & Tx Abdominal Pain
Definition
Sharp pain caused by spasm of round ligaments...enlarged uterus make them more susceptible, pain associated with abrupt movements, other causes: contractions, gastroenteritis, appendicitis & renal or billary colic
Help: physical exercise within tolerance, rise & sit gradually, avoid sudden movements, rest with local heat appplication
Term
Cause & Tx leg cramps
Definition
caused by a build up of acids that cause involuntary contractions of the affected muscles, usually at night, more common in 2nd & 3rd trimesters
Help: walk around, stretch & massage the affected muscles to disperse the build up of acids
Term
Cause & Tx Leucorrhea
Definition
Vaginal flow is increased - whitish in colour & variable consistency, non-problematic unless accompanied with itching, burning, foul odour or labial swelling; change in quantity or quality should be differentiated from leaking or ruptured membranes
Help: regular hygiene & wear cotton underwear
Term
Cause & Tx Headaches
Definition
Can be related to sinus congestion, increased vascular blood flow, nasal oedema, fatigue, tension eyestrain & migraines
Help: relaxation & warm compresses, be alert for headaches that are accompanied by dizziness, blurred vision(possible sign of preeclampsia)
Term
Cause & Tx Fatigue
Definition
can be related to basal metabolic rate, increased demand on CV & renal systems, loss of sleep due to urinary frequency, emotional factors, stress anxienty, depression
Help: proper nutrition & exercise & treat possible anaemia with diet & exercise
Term
Cause & Tx sleep difficulties
Definition
early in pregnancy (psychological stressors & frequency of urination), later in pregnancy (difficulty finding position of comfort, fetal movements, feeling short of breath)
Help: plan quiet time before going to bed, limit fluid intake prior to sleeping, pillows to support back, abdomen & legs, warm bath or shower and massage, meditation & visualisation, warm milk

gum hypertrophy, gum bleeding (gingivitis) & tooth decay (more rapid in pregnancy)
Help: soft toothbrush, mild toothpaste, daily flossing, dental work can be done with anaesthesia
Term
Cause & Tx Heartburn/reflux
Definition
Caused by reflux of acid gastric contents into oesophagus, most problematic after 30wks, main cause: relaxing effect of progesterone on muscle of cardiac sphincter
