Q

Heat Loss

A
  • conduction=loss to object touching baby
  • convection=loss to surrounding air
  • radiation=loss to object at greater distance (window nearby)
  • evaporation

Heat production-nonshivering thermogenesis; metabolism of brown fat (sympathetic nervous system); increased metabolic rate.

Cold stress leads to: hypoglycemia, weight loss, respiratory distress, hyperbilirubinemia

  • GI-poor digestion and absorption, poor gag reflex, incompetent cardiac sphincter, small stomach capacity, high conc of whey to casein ratio, deficient of Ca and P, increased BMR and O2 req’d related to effort of sucking, feeding intolerance and necrotizing enterocolitis r/t decr blood flow to intestines
  • need supplemental vitamins, vit E
  • no weight gain expected until day 5
  • 120 cal/kg/day
  • 34 wks or greater for oral feeding
  • may have patent ductus arteriosus

20
Q

A
  • Causes-smoking, HTN, DM
    • perinatal mortality 8X that of AGA
  • Symmetrical (SGA)-chronic growth restriction, utero-placental insufficiency, chronic hypoxia
  • Asymmetrical (IUGR)-acute compromise of uteroplacental blood flow, head large for body bc brain growth spared, begins later in gestation >28 wks.
  • Characteristics: sparse hair, wide suture lines, scaphoid abd, loose dry skin, malnourished
  • Complications: perinatal asphyxia, aspiration syndrome (gasping at birth), heat loss, hypoglycemia, hypocalcemia, polycythemia (from hypoxia); later-learning difficulties.
21
Q

Third Stage of Labor

A

birth until placenta is delivered

administer oxytocin

care of infant: Apgar at 1 & 5 minutes, sucition as needed, thermoregulation, identification

watch for signs of placental separation (lengthening of cord, gush of blood, change in uterine shape)

document time and method of placental delivery (spontaneous, assisted, shiny/dirty)

21
Q

A

alcohol

aminoglycosides

anticonvulsants

statins

antineoplastics

antithyroid

cocaine

DES

folic acid antagonists

infections (CMV, Herpes, HIV, Rubella, Syphilis, Toxoplasmosis, varicella)

lithium

mercury

retinoic acid

tetracycline

tobacco

warfarin

22
Q

Tocolytics

A

-Beta-adrenergic agonist: Terbutaline (caution with DM, increased HR > 110, pulmonary edema)

-CCBs: Nifedipine (hold for low BP)

-Prostaglandin inhibitor: Indocin

-CNS depressant: MgSO4

22
Q

Alcohol During PG

A
  • Fetal Alcohol Syndrome -includes malformations (facial), smaller head
  • Fetal Alcohol Effects -cognitive difficulties-life long affecting learning, behavior, relationships
  • affects speech, hearing, language, eating, sleeping
  • leading cause of mental retardation
  • SGA/IUGR (growth deficits)
  • difficulty blocking out repetitive stimuli
  • impulsivity
  • early on=sleeplessness, crying, abn reflexes, hyperactivity, jittery, excessive mouthing behaviors, hyperactive rooting, incr non-nutritive suck
23
Q

C-Section

A
  • catheter
  • type & cross
  • baby out STAT bf anesthesia affects it
  • pre-op meds: anti-emetics, bicitra (antacid), atropine (post-op N/V), antibiotics
  • Low, transverse-heals better, less likely to rip, can have VBAC
  • Low, vertical-can be extended upward to make larger incision if needed, more likely to rupture during subsequent birth
  • Classical (verticla, up higher)-most likely of incisions to rupture during subsequent births, elimnates VBAC.
24
Q

DM in PG

A
  • blood sugar control is important-baby less likely to be hypoglycemic, jaundice, LGA (so less trauma at birth)
  • placental hormones cause insulin resistance so that glucose is available for the fetus
  • GDM-first dx during PG, may be asymptomatic, resolves after delivery, increased risk of DM later in life
  • DM in general-decreased insulin during 1st trimester, increased insulin 2nd trimester, increased insulin during labor (bc more energy needed), greater risk of DKA, vascular disease may progress.
  • complications: hydramnios, preeclampsia, ketoacidosis, vaginitis, UTI, PROM
  • for baby: death, congenital anomaly (cardiac), birth trauma (LGA), IUGR, respiratory distress syndrome, hypoglycemia after birth
  • GDM-screen 24-28 wks, 50 g glucose soln, serum glucose > 130 perform GTT test (3hours). GTT is gold standard-fasting: 1 hr > 180, 2 hr >155, 3hr>140
  • GDM mgt-diet, exercise, blood glucose monitoring; fetal-kick counts, NST, US for growth and/or AFI (amniotic fluid index), BPP, amniocentesis for lung maturity (lecithin-sphingomyelin ratio)
  • Post Delivery-mom rapidly returns to normal, newborn-monitor BS >40, assess jitteryness, prompt feeding, assess birth trauma
  • Newborn is used to high BS-compensates with high insulin; at birth BS goes down rapidly, but insulin remains high.
25
Q

Fourth Stage of Labor

A

1-4 hours post-delivery

VS of mother, fundus, lochia, bladder, perineum, pain (return of sensation)

promote bonding

promote comfort

  • intrauterine asphyxia r/t withdrawal (hyperactivity-increased O2 consumption)
  • intrauterine infection
  • S/S of withdrawal=poor weight gain, N/V, tremors, seizures, SIDS
