Q

Maternal Conditions That Permit Breastfeeding

A

-Breast abscess - Breastfeeding should continue on the unaffected breast
-Cytomegalovirus in mother
-Herpes simplex lesions - breastfeed on unaffected breast
-Hepatitis B - Babies should receive Hepatitis B vaccine within 48 hours of birth
-Hepatitis A or C – There is no definite case of mother to baby transmission via breast milk;
-Mastitis – infection in the milk duct. If breastfeeding is very painful, breast milk must be removed by expression to prevent progression of the condition;
- Substance use – Mothers should be encouraged not to use these substances
- A medical condition that may make it difficult to breastfeed more frequently, such as intolerable pain that is unrelieved by intervention.

Q

lactogenesis

A

-Ductules enlarge into lactiferous ducts and sinuses, where milk collects behind the nipple
-After birth, a precipitate decrease in estrogen and progesterone levels triggers release of prolactin
-Prolactin levels highest during first 10 days after birth
-Prolactin produced in response to infant suckling and emptying of breasts
-Milk is constantly produced as the infant feeds.
-Oxytocin - Stimulated by infant suckling
-Responsible for milk ejection reflex (let down reflex) myoepithelial cells surrounding the alveoli respond to oxytocin by contracting and sending the milk forward through the ducts to the nipple

29
duration of feedings
The average time for early feedings is 30 to 40 minutes Don’t go longer than 5 hours between feedings No pacifiers for 6-8 weeks (decreases nipple confusion)
30
formula supplementation
-The CPS recommends that, unless a medical indication exists, supplements should not be given to breastfeeding newborns -Possible indications for supplementary feeding include hypoglycemia, ineffective feeding, dehydration, weight loss of more than 10% associated with delayed lactogenesis, or delayed passage of bowel movements or meconium stool continued to day 5.

35
weaning
Weaning is initiated when infants are introduced to foods other than breast milk and concludes with the last breastfeeding. Gradual weaning is easier than abrupt
36
milk banking
Fresh milk -deep freeze 6 months+ -fridge freezer 3-4 months -fridge 8 days -room temp; colostrum 24 hours; mature milk 10-12 hours Thawed breast milk - do not refreeze -can last in the fridge up to 24 hours -room temp 1 hour
37
engorgement
-breasts become enlarged, reddened, painful, shiny, and edematous. -Nipples may become effaced, milk flow decreases, and the newborn can have difficulties latching on. -Factors that contribute to engorgement include delayed initiation of breastfeeding, infrequent or time-restricted feedings, feeding supplementation, inefficient infant latch, breast surgery, or any situation where milk stasis occurs -Apply warmth to breast before, gentle massage, cold compress after feeding to help with pain
38
mastitis
-Infection/inflammation of breast -Causes - Inadequate emptying of the breasts is common, related to engorgement, plugged ducts, a sudden decrease in the number of feedings, abrupt weaning, or wearing underwire bras. Sore, cracked nipples
39
plugged milk duct
Small white pearl visible on tip of nipple
40
ready to feed formula
-no water needed. -Expensive -sterile until the can is opened. -Babies who have the greatest chance of infections should have sterile formulas. (premature, low birth weight, under two months of age, weakened immune system)
41
liquid concentrate formula
-needs to be mixed with sterilized water. -sterile until the can is opened
42
powder formula
-needs to be mixed with sterilized water. -Cheapest -Not for premature babies -Powdered formula is not sterile and may carry harmful bacteria that can make your baby sick if not prepared safely
43
formula storage
The bottle of formula can be put back in a fridge for up to 24 hours from the time it was prepared as long as you can answer “yes” to each of these statements: 1. The bottle of formula has been kept cold while travelling. 2. The bottle of formula has been out of the fridge for less than 2 hours. 3. The baby has not taken any formula from the bottle, even only a few mouthfuls.
44
warnings about formula

-Preterm and multiple birth rates are leading causes of neonatal morbidity and mortality. Other causes of neonatal death: -Low birth weight -Respiratory distress syndrome -Sudden infant death -Effects of maternal complications
59
first trimester screening
-Aneuploidy - having one or more extra or missing chromosome (eg, downs syndrome) -ultrasound examination for nuchal translucency (measures fluid in nape of neck) >3mm highly indicative of genetic disorder or physical anomalies >3.5 mm increased risk of CHD -Amniocentesis to confirm or echo
60
second trimester screening
MSAFP levels are used as screening tool for open neural tube defects and abdominal wall defects
61
Noninvasive prenatal testing (NIPT)
-Blood test -Screens for aneuploidy -done at 10-12 weeks -Uses a sample of maternal blood which has broken down components of fetal cells Measures amount of cfDNA circulating in maternal blood and compares it to known standards -Ex: if more than the expected amount of chromosome 21 DNA is detected, it can then be assumed that the fetus is contributing the extra amount and therefore has trisomy 21 Only free if >40 when delivering or already have a baby with trisomy
62
ultrasonography
-Fetal activity, gestational age, fetal growth, fetal anatomy, placental position and function -Done around 6 weeks -Provides visual assistance for invasive procedures -Full bladder helps push uterus up and get a better picture
63
amniocentesis
-Performed to obtain amniotic fluid which contains fetal cells to test for chromosomal problems -Under ultrasound, a needle is inserted trans abdominally into the uterus and amniotic fluid is withdrawn -Possible after 14 weeks -Can assess fetal lung maturity late in pregnancy
64
amniocentesis risks
Leakage of amniotic fluid through puncture hole Maternal hemorrhage Infection Accidentally puncture bladder or intestine Amniotic fluid embolism Labour, miscarriage
65
Chorionic villus sampling (CVS)
-Technique for genetic studies -Earlier diagnosis and rapid results -Performed between 10 and 13 weeks of gestation -Equal to amniocentesis in accuracy and risk -Indications similar to amniocentesis -Removal of small tissue specimen from fetal portion of placenta -Chorionic villi originate in zygote. -Tissue reflects genetic makeup of fetus.
66
Percutaneous umbilical blood sampling (PUBS)
-Insertion of needle directly into fetal umbilical vessel under ultrasound guidance -Direct access to fetal circulation -Used for fetal blood sampling and transfusion -Second and third trimester
67
Maternal serum alpha-fetoprotein (MSAFP)
-used as screening tool for neural tube defects -Detects 80% to 85% of all open NTDs and open abdominal wall defects early in pregnancy -Screening recommended for all pregnant women at 15-20 weeks -Triple- and quad-screening to detect autosomal trisomies (21 Downs and 18 at 16-18 weeks) -Not diagnostic just indicates a possibility
68

69
third trimester assessment
Fetal movement counting Electronic fetal monitoring Nonstress test (NST) Contraction stress test (CST) Biophysical profile (BPP) Amniotic fluid volume (AFV)
70
fetal movement counting
-Fetal movement is a reassuring sign -Decreased fetal movement → decreased placental perfusion, fetal acidemia -In a reclined position should feel 6 movements within 2 hours
71
electronic fetal monitoring
-Most common method of fetal assessment -Hypoxia or asphyxia -redistribution of blood flow to vital organs -Decreased total oxygen consumption -Switch to anaerobic glycolysis
72
non stress test (NST)
-a normal fetus produces characteristic heart rate -patterns in response to fetal movement. -FHR should accelerate with movement -can be performed easily and quickly in an outpatient setting -It is noninvasive and has no known contraindications. -Disadvantages → high rate of false-positive results for atypical or abnormal tracings
73
NST procedure
-Empty bladder, sit semi fowlers with slight left tilt -FHR is recorded with doppler, tocodyna, ometer detects uterine contractions or fetal movements -Abnormal tracing persistently lacks accelerations after 80 minutes or contains significant abnormality of baseline heart rate or variability or shows evidence of significant decelerations -Normal NST is predictive of good perinatal outcome for 1 week
74
Contraction stress test (CST)
-Evaluest response of fetus to induced contractions to identify poor placental perfusion -The goal of a CST is to induce three contractions, each lasting 1 minute within a 10-minute period so that the fetal heart response to the contractions can be evaluated Nipple-stimulated contraction test -Massage nipple for 2 minutes, rest for 5, repeat Oxytocin-stimulated contraction test -Iv infusion of oxytocin -Negative result = no late decelerations -Positive result = repetitive late decelerations -Provides a warning of fetal compromise earlier than NST
75
contraction stress test contraindications
preterm labour, placenta previa, vasa previa, cervical insufficiency, multiple gestation, previous classical uterine incision for c section
76
Biophysical profile (BPP)
-Non invasive -used to assess current fetal well-being by observing fetal breathing movements, fetal movements, fetal tone, and amniotic fluid volume Score interpretation -Score of 8-10 is healthy -Score of 6 means we need to retest in 24 hrs -Score of 6 with abnormal fluid means delivery must happen now -less than 6 means delivery
77
BPP components
1) breathing movements -at least one episode continuing more than 30 seconds 2) movements -at least 3 body or limb movements 3) tone -an episode of active extension with return to flexion, or opening and closing of the hand 4) amniotic fluid volume -at least one cord and limb free pocket which is 2cmx2cm
78
amniotic fluid volume
-Abnormalities in AFV are frequently associated with fetal disorders. -depths (in centimeters) of amniotic fluid in all four quadrants surrounding the maternal umbilicus are totalled, resulting in an amniotic fluid index (AFI) -AFI less than 5 cm = oligohydramnios -AFI more than 25 = polyhydramnios
79
doppler blood flow
-systolic/diastolic flow ratios and resistance indices to estimate blood flow in various arteries. -17-22 weeks -Vessels studied Fetal umbilical and middle cerebral arteries; maternal uterine arteries -it is a helpful tool in the management of high-risk pregnancies due to intrauterine growth restriction (IUGR), diabetes mellitus, multiple fetuses, or preterm labour

Perinatal asphyxia Immunodeficiency MAS Hypoglycemia → oral feedings or IV dextrose Hyperglycemia Heat loss → external heat source (radiant warmer or isolette) Polycythemia
252
Large for gestational age difficulties
-Greater risk for morbidity -Higher incidence of birth injuries -Asphyxia -Congenital anomalies
253
Infants of mothers with diabetes
Macrosomia Hypoglycemia shortly after birth Hypocalcemia and hypomagnesemia Cardiomyopathy Hyperbilirubinemia and polycythemia RDS Congenital hyperinsulinemia → can lead to reduced surfactant → RDS
254
birth trauma
-Physical injury sustained during labour and birth -Elective Caesarean birth is chosen for some pregnancies to prevent significant birth injury.
255
birth trauma: skeletal injuries
-Linear fracture -Depressed fractures (ping pong ball indents) -Clavicle most commonly fractured
256
birth trauma: peripheral nervous system injuries
Erb palsy → arm just hanging there, not flexed Brachial palsy Facial nerve paralysis Phrenic nerve paralysis → paralyzes the diaphragm (cyanosis and resp distress)
257
birth trauma: neurological injuries
Intracranial hemorrhage Cerebral palsy Seizures Hydrocephalus Spinal cord injury Hypoxic ischemic encephalopathy
258
Hypoxic ischemic encephalopathy
Reduction in oxygen delivery to the fetus (caused by placental insufficiency, umbilical cord accidents, abnormal fetal presentation, prolonged late stages of labour)
259
sepsis
-GBS leading cause of sepsis -Early onset (congenital) within 24-48 hours after birth -Late onset (occuring after 72 hours of age) -Acquired through the infant's environment (hospital-acquired) -Apnea, tachypnea, grunting, nasal flaring, hypotension, tachycardia, lethargy, hypotonic, seizures, vomiting, pallor, petechiae -50% mortality rate
260
TORCH Screening
group of infectious diseases that may contribute to newborn illness Toxoplasmosis Other (HBV, parvovirus, HIV, West Nile virus) Rubella Cytomegalovirus (CMV) Herpes simplex virus (HSV)
261
Leading cause of neonatal hearing impairment & cognitive delay
Neonatal Cytomegalovirus Infection
262
covid-19 in neonates
-changes the placental structure which may damage the placental bloodflow to baby, negatively effecting fetal growth -no convincing evidence of in-utero transmission of COVID-19 to the fetus -The rate of neonatal infection is very low -Severity of infection in infants is less then in adults
263
covid-19 and breastfeeding
-breastfeeding is not contraindicated for mothers who are suspect or COVID-19 positive -just use precautions (hand washing, masks, coughing away fro infant)
264
Nursing Care of Infant With Infectious Disease
Hand hygiene most important to reduce spread Goal is to identify causative organism Routine precautions Pregnant health care provider precautions Specimen collection Assist family with coping
265
hemolytic disorders
-Hemolytic disease occurs when blood groups of the mother and newborn are different. -Rh incompatibility: -ABO incompatibility -Occur when maternal antibodies are present naturally or form in response to antigen from fetal blood crossing placenta and entering maternal circulation -High risk of jaundice
266
The most common major congenital anomalies that cause serious problems in neonate are as follows
Congenital heart disease Abdominal wall defects Imperforate anus Neural tube defects Cleft lip or palate Clubfoot Developmental dysplasia of the hip
267
Phenylketonuria
-deficiency in or absence of the enzyme needed to metabolize the essential amino acid phenylalanine into tyrosine → hyperphenylalaninemia -failure to thrive, frequent vomiting, irritability, hyperactivity, cognitive impairment. -Needs low diet in phenylalanine and medications
268
Galactosemia
-three enzyme deficiencies → galactose accumulates in blood -Hepatic dysfunction → cirrhosis & jaundice, enlarged spleen -Vomiting, diarrhea, therapy, weight loss. -Eliminate all lactose including breastmilk
269
Hypothyroidism
-poor feeding, lethargy, prolonged jaundice, bradycardia, cyanosis. -large fontanels, hoarse cry, constipation -Needs medications, lifelong thyroid hormone replacement
270
neonatal abstinence syndrome
-set of behaviours exhibited by newborns exposed primarily to opioids -Intrauterine exposure to drugs may lead to neonatal intoxication or withdrawal -Is not always illicit drug use. -The presentation of NAS can be similar to, and must be distinguished from: neonatal sepsis -Hypoglycemia, -hypocalcemia -intracranial hemorrhage. -If NAS is left untreated, seizures from withdrawal and intracranial hemorrhage may occur
271
Neonatal Abstinence Syndrome: signs and symptoms
Neurological -Irritability, high-pitched cry -Seizures, hyperactivity, tremors, hypertonic muscles Autonomic -Sweating, hyperthermia, mottled skin, nasal stuffiness, tachypnea Gastrointestinal -Poor feeding, uncoordinated or ineffective suck -Vomiting, loose stools, dehydration, weight loss Miscellaneous -Disrupted sleep patterns, excoriation, temp instability
272
NAS: treatment
-eat, sleep, console Reduce environmental stimuli Rooming In Caregiver presence Skin-to-skin contact Baby held by caregiver Safe swaddling Optimal feeding at early feeding cues Quiet, low light environment Non-nutritive sucking/pacifier Rhythmic movement Additional help/support in room Cue-based responsive care Limiting visitors Caregiver self-care/rest pharmacological --> morphine
273
pessary
used for uterine prolapse A fitted pessary may be inserted into the vagina to support the uterus and hold it in the correct position
274
risk factors for PPH
-overdistended uterus (twins) -magnesium sulphate during labour -forceps assisted birth -oxytocin induced labour -high parity
275
side effects of hemabate
headache, nausea, vomiting, diarrhea, fever, chills, tachycardia, hypertension
276
neonatal syphillis
copper coloured maculopapular rash on the palms, and around the mouth and anus
277
