25
HR
assess at rest newborn circulation: increased systemic vascular resistance, decreased pulmonary vascular resistance, enhance perfusion of body system; foramen ovale close w/n 1-2hr, ductus arteriosus close, ductus venosus close (liver perfusion) assess brachial and femoral with arms extended, bilaterally
26
BP
in nursery or before going home cap refill <2-3s highest right after birth, lowest 3hr after sensitive to change in volume, varies by birth weight and GA
27
heat loss
stabilize internal core temp in narrow range thermoregulation by metabolic rate and O2 consumption flexion decreases SA and retains heat convection (air), radiation (no contact), evaporation (moisture), conduction (contact - warm stethoscope, scale, blanket)
28
issues with thermoregulation: causes of heat loss
higher SA to body mass ratio, low SQ fat, higher body water content, immature skin (higher evaporation), poor metabolic mechanism for responding to thermal stress (cant shiver), altered skin blood flow (peripheral cyanosis) preT at higher risk bc lack of flexes posture for preserving heat, very thin skin with capillaries close to surface
29
hypothermia s/s
acrocyanosis and cool, mottled, pale skin hypoglyc, transient hypergly, brady, tachypnea, restless, shallow and irregular resp, resp distress, apnea, hypoxemia, metabolic acidosis, decreased activity, lethargy, hypotonia, feeble cry, poor feed, decreased weight gain
30
hyperthermic: causes
incubator, radiant warmer, ambient env, maternal fever, epidural anesthesia, phototherapy lights, sun, excessive bundling, infection, CNS disorder (asphyxia), dehyd
31
hyperthermic: s/s
tachy, tachypnea, apnea, warm extremities, flushing, perspiration (term), dehyd, lethargic, hypotonia, poor feed, irritable, weak cry
32
hyperthermic: consequences
hypoT and dehyd: d/t water loss seizures and apnea: bc increased core temp hyperNa resp distress
33
hyperthermic: management
adjust env, move way from heat source, undress, decrease air temp, feed freq to replace fluids
34
brown fat
non shivering thermogenesis, skin receptors sense temp change, use brown fat for heat 26-28 weeks gestation -> 3-5 weeks after birth
35
temperature management
kangaroo care for stable infants radiant warmers for c/s, unstable, close assessments
36
measurements
double weight by 6 months, triple by 12 head circumference > chest circumference (nipple line) term: lose 5-10% preT: lose 15%
37
skin
color: pink, acrocyanosis (ok after birth and first 24 hours), central cyanosis (circum oral, bad oxygenations, assess) preT: thin and transparent with veins prominent, less lines on feet T: opaque and disappearance of vernix (lipid rich) postT: peeling
38
resting posture
extended: preT flexed: term
39
head
1/4 body fontanelles: soft and flat, bulge with cry, separated, approximated, overlapping sutures (molding) forceps/vacuum marks
40
head: cephalohematoma
collection of blood between cranial bone and periosteal membrane, increased jaundice and anemia and hypoT, does not cross sutures, btw 1st and 2nd day, disappears after 2-3 weeks or may take months
41
head: caput succedaneum
soft tissue swelling - collection of fluid, edematous swelling of scalp, crosses sutures, present at birth or shortly after, reabsorbed in 12 hours or a few days after birth
42
eye variation
subconjuctival hemorrhage: will resolve, increased P, normal, vessels in sclera break transient strabismum: cross eyed, eyes still developing, not treated at birth dolls eyes: turn baby, eyes move in opposite direction, under developed head-eye coord
43
ears
low set = in line with eye (intellectual disability) preT: shapeless and flat, no recoil terms: some cartilage and slight incurring of upper pinna, good recoil
44
mouth
suck, cleft lip and palate (aspiration), precoscious teeth, epstein's pearls (cysts, harmless)
45
back
spine - straight and flat sacral dimple: pit at base, may have tuffs of hair, US if it doesnt close (hole) bc r/o spina bifida occulta or tethered cord s
46
spina bifida occulta
spine doesnt close properly around spinal cord
47
tethered cord s
tissue attached to cord limits its movement - causes weakness, numbness and bladder and bowel problems
48
lanugo
decreased with increasing GA more with non White
49
breastbud
term = 0.5 to 1cm
50
umbilical cord
3 vessels (2A, 1V) observe for umbilical hernia (AA, close by 2yr)
51
genitalia: M
withold circ if issue - consult urologist hypospadias, epispadias, phimosis (cant retract foreskin), hydrocele (fluid collection around testes), cryptorchidism (dont drop) preT: small scrotum, few rugae, testes palpable in inguinal canal T: testes in lower scrotum which is pendulous and covered with rugae
52
genitalia: F
preT: clit prominent, labia majora small and separated T: labia majora covere minora and clit pseudomenstruation: vaginal discharge tinged with blood d/t withdrawal from maternal hormones
53
vernix
lubricate skin
54
milia
clear sponatneous (1mo), exposed sebaceous glands, white spots, face and nose, dont bother them
55
telangiectatic nevi
pale pink or red spots, fade by age 2
56
mongolian spots
non white, note, look like bruise, back or butt, 4yrs, non white
57
nevus flammeus
capillary angioma, below dermis, non elevated, red-purple, face, dont go away or fade
58
strawberry mark
capillary hemangiomas, dermal and subdermal, raised, dark red, grow rapidly but may shrink and go away (9-10yr), leave alone
59
fractured clavicle
birth, large, shoulder dystocia, move both arms equally
60
erbs palsy
5th and 6th cervical roots of brachial plexus, move extremities equally
61
simian crease
down s 1 transverse palmar crease
62
syndactyly
webbing
63
polydactyly
extra digits
64
clubfoot
cant turn midline or realign
65
sole (plantar) creases
higher GA = proceed to heel
66
hip dislocation
barlows maneuver: will feel demur move out of acetabulum (pop out) ortolanis maneuver: + = hip click (pop in)
67
RDS: rf
preterm, c/s, infection, cold stress/hypothermia maternal DM -> hyperinsulinemia and hypergly reduce fetal surfactant production
