- Reason for Slow Fetal Growth
- Prescription drugs, smoking, psychoactive drugs, maternal malnutrition, multiple births
- BPD
- Chronic lung disease, from baby having air forced into their lungs, repeated hypoxic events, risk for asthma, risk for pneumonia, irritable
- Kangaroo Care
- Mother spends at least an hour a day holding hertiny newborn between her breasts, newborns slept more deeply and spent more time alert
- Teratogen
- Substances and conditions that increase the risk of prenatal abnormalities, increase risk of harm, not always cause damage
- Fourth to Sixth Month of Pregnancy
- Heartbeat becomes stronger, finger and tonails form, hair grows, brain grows six times size, sleep wake cycles (28 weeks), body movement becomes reactive
- After birth
- Placenta born, release of oxytosin causes uterus to go into prepregnancy phase, placenta should come naturally (hemorrage), to help involution breast feed within 1 hour
- Preterm vs. newborn
- Differenceis in maturation of the neurological, respiratory and cardiovascular systems
- Preterm births
- Babys born before 37 weeks, don't get mom's antibodies so more at risk if they get sick, given gantamycin which makes them deaf, less fat means cold, stress makes brain bleeds
- Iatrogenic effects
- Measures to keep babies alive, cause a lot of mental retardation
- Paternal Alliance
- Intimate communication crucial throughout pregnancy, commitment by both parents to cooperate in raising the child
- Staydol
- Babies will be groggy and have trouble eating, used for panicing moms, makes mom relax
- Magical Beginnings with Chopra
- Have mind body connection, learn about water births, yoga positions, aroma therapy and relaxation techniques one week each
- Active phase
- Contractions 5 min apart, keep walking, dialation 3-9cm, contractions get painful, want to get to hospital when cervix 5-6cm, body expels everything, feel urge to push at end
- Hospital Births
- No better for baby than family centered births, 41% of US births
- Intensive care infants
- Placed in nurseries, deprived of gentle rocking in darkness, regular handling invoved in feeding and bathing, provide with massage and soothing stimulation
- Doula
- Woman who helps other women with labor, being hired by more women
- Early phase
- Feels like back hurting, beginning contractions, starts to feel like menstreul cramps, can be in for 1-24 hours, should eat light and sleep, water breaks and lose mucus plug
- Interaction Effect
- One substance intensifies the effects of another
- Genetic Vulnerability
- To what extent a developing organisms genetic makeup makes them susceptable to a teratogen (Spina bifida when sine does not close properly, anecephaly when part of the brain doesn't form, boys have more problems from behavioral teratogens)
- Anoxia
- Temporary lack of oxygen
- Small for Gestational Age
- Fetuses that gain weight to slowly through pregnancy, signifies impairment
- Teratology
- Study of birth defects and risk analysis, includes timing, dosage and genetic vulnerability
- Apgar Scale
- Assessment to check five of baby's vital signs, heart rate, breathing, muscle tone, color, reflexes, one minute after birth, five minutes after birth, if bad check at 10,12,14,20min, after 5min brain damage can occur
- Braxton Hicks
- Prelabor contractions, if you get up and walk around will go away,
- Last Month of Pregnancy
- Fetus will change position and turn upside down, fetal brain releases certain hormones cases uterine muscles to contract
- Contraction stage
- Divided into Three phases,Early phase, active phase, Transition phase, becoming dialated (pain)
- Extremely low birthweight
- Weight of less than 2 lbs 2oz, 1kg
- High-risk infants
- More distractible, less obedient, high rates of obesity and diabetes
- Embryo Period
- First sign of the human body appears, line becomes the neural tube, head begins to take shape (4th week), buds to become arms and legs appear (5th week), embryo has all basic organs and body parts (except for sex organs)
- Age of viability
- Age at which a preterm newborn can survive, about 22 weeks, weight and maturity are crucial
- Transition phase
- 9-10cm dialation, contractions begn to connect, shortest stage of labor 30min
- Effacement
- Thinning of the lip around the cervix
- Syphillis and AIDS
- Less likely to harm fetus if the woman is diagnosed and treated early
- Cesarean Section
- Fetus removed through incisions in mother's abdomen, 28% US births
- Third month of Pregnancy
- Development of the sex organs begins in ninth week, at end of third month has all body parts, organs aren't functioning yet
- Repeated hypoxic events
- Can cause brain damage at birth
- Preterm
- Baby born 3 or more weeks before standard 38 weeks (+SGA = most of low birthweight babies)
- Three stages of labor
- Contraction stage, Parturition stage, After birth
- Bradly Method - 80s
- First classes in first trimester to learn about nutrition, exercises and talk, develop birth plan, last trimester is second class with relaxation techniques to help with pain, relax through pain, think short term, most won't need epideral
- Threshold Effect
- Teratogens that are harmless until exposure reaches a certain level (vitamen A)
- Behavioral Teratogens
- Teratogens that harm the brain and make a child hyperactive, antisocial or learning disabled
- Postpartum Depression
- Sense of inadequacy and sadness, mother finds normal baby care to be burdensome, thoughts of neglecting or abusing the infant
- Newborns first minutes
- Breathe or cry on own, fingers grab anything, mucus in babies throat cleared, umbilical cord cut to detach placenta, wrapped in blanket
- Parent Infant bond
- Speculated to develop in the first few hours of life
- Brachial Plexus Injury
- Baby's shoulder gets stuck
- Critical Period
- Time of greatest susceptablility, no safe period for behavioral teratogens
- Parturition Stage
- Signaled by crowning, baby born covered in vernix (lubricant, lotion), pat baby off
- Father support
- Can be crucial in helping mother to be stay healthy and nourished, marriage and healthy pregnancies have high correlation
- Fetus
- From the ninth week of conception to birth
- Low birthweight
- Weight of less than 5.5 lbs, 2.5kg
- Epideral
- Given in between vertebral disks, if put in wrong place could cause back problems, messes up nervous connection, need to sit up soon after birth to get organs back in place
- Germinal Period
- First 14 days, week after conception multipyling cells seperate into outer shell that will become the placenta and the inner cell that will become the embryo, first task of the outer cells is implantation
- Lamaze - 50s
- First to look at anesthesia, if given baby stops helping which leads to increased use of forceps and longer labor, babies groggy first few days, help moms manage pain without meds, concentrate and distract yourself away from the pain, needa coach because easy to hyperventilate under labor, many start to late and don't gain enough experience
- Final Three Months of Pregnancy
- Fetus gains 4.5 lbs, relationship between mother and baby intensifies, communication can begin (28th week), fetus feels maternal movement
- Leboyer - 70s
- Makes birth pleasant for baby, lower lights, warmer, fathers shouldn't be in delivery room, problems were dad needs to be present and hospitals need to be cold to inhibit bacterial growth
- Birth Times
- After 12 hours of active labor for first born, 7 hours for subsequent births
- Very low birthweight
- Weight of less than 3 lbs 5oz, 1.5kg
- Before Labor
- Amniotic fluid trickles out, hard to tell if sack broke or peed, bloody show is seeing blood in urine and seeing mucus plug in cervix come out which means labor is coming
- Cerebral Palsy
- Difficulties with movement control resulting from brain damage, often from genetic vulnerability or anoxia
- Three approaches of Childbirth
- Leboyer (freud), Lamaze Theory, Bradly Method, Magical beginnings by Chopra
