25
Placenta Increta
deep penetration of the myometrium by the placenta Adherent retained placenta (2)
26
Placenta percreta
Uterus is perforated by the placenta Adherent retain placenta (3)
27
Treatment of Adherent retained placenta
Blood replacement and hysterectomy, placenta is retained too deep, will continue to bleed
28
Inversion of the uterus
Complete: red mass protrudes 20-30 cm out of the introitus (vagina) Incomplete: palpated smooth mass that comes through dilated cervix Can be life threatening Factors: Fundal implantation, uterine atomy, excessive cord traction, adherent placenta tissue
29
Subinvolution of Uterus
Late pp bleeding r/t retained placenta fragments, pelvic infection SS: prolonged lochial discharge, irregular or excessive bleeding, hemorrhage, larger than normal uterus + boggy Treat cause - may include remove fragments and treat with antibiotics
30
Hypovolemic shock
Emergency, vessels constrict so the blood goes to vital organs, cell death occurs, lactic acid and acidosis increases Management: Restore blood volume (fluids and replacement) Treat cause of hemorrhage
31
Hypovolemic shock interventions
Signs may not appear until 30-40% of volume has been lost, improve/monitor perfusion, take vitals, watch I/O
32
DIC
Form of clotting where all the clotting factors are consumed leads to widespread bleeding SS: Unusual bleeding from IV site, venipuncture sites or petechia under BP cuff
33
DIC management
Treat underlying cause (arrest, hemorrhage, preeclampsia, sepsis) Replace volume, replace blood, apply oxygen, monitor labs and perfusion + IO
34
Thromboembolic Disease
Formation of clot in vessel but inflammation Risk: hypercoagulation, venous statis, obesity, smoking Increasing ambulation decreases risk
35
Thromboembolism Superficial
Pain and tenderness in lower extremities with warmth, redness and enlarged vein over the site
36
Deep thromboembolism
More common in pregnancy, unilateral leg pain, calf tenderness, swelling, redness and warmth, positive homans (flex knee and ankle causes pain in leg)
37
PP Infection risk
Prolonged labor, c section, internal monitoring, diabetes, immunosuppression
38
Endometritis
Most common PP infection - begins as localized infection at placenta site SS: fever, chills, pelvic pain, foul smelling discharge
39
Mastitis
Unilateral, after flow of milk has been established, edema obstructs flow, can progress into an abscess, most common staph aureus SS: chills, fever, malaise, local tenderness, pain, swelling, redness Treatment: antibotics and frequent emptying
40
Best way to prevent infections
Hand hygiene
41
Physiologic Adjustment of the NB
Establish and maintain respirations, circulatory changes, regulating temperature, ingesting retaining and digesting nutrients, eliminating waste and regulating weight Breathing, Temp, Nutrients, Waste and Weight
42
NB Behavioral Adaptation Tasks
Pattern of sleep, regulating arousal, processing storing and organizing stimuli and relationship with providers
43
Transition period for NB
First 6-8 hours
44
What does clamping the cord do?
Increase the baby BP, increased circulation and lung perfusion
45
Chemical stimulation of respiratory
Decreases prostaglandin, causes fetal hypoxia Contractions lead to decreased Po2, increased PCO2 and a lowered pH Planned C-Section babies at risk because they did not get this benefit
46
Mechanical Respiratory stimulation
Intrathoracic pressure when the fetus is going through the uterus
47
Thermal Factors stimulating respiration
Extrauterine environment is colder (72 standard) than the uterus, the skin
48
Sensory Factors stimulating respiration
handling of baby, suctioning (mouth then nose or will aspirate) drying, pain, lights/sounds/smells
49
Surfactant
Alveoli are lined with this and the lung expansion at birth releases it. The surfactant reduces the pressure required to keep the alveoli open
50
Respiratory Vitals in NB
30-60 per minute with pauses of 15 seconds normal If pause is >20 it is apnea and that is problematic
51
Signs of respiratory distress
Nasal flaring, retractions, grunting, seesaw respirations, pallor, central cyanosis
52
Cardiovascular NB adaptations
Increased pulmonary blood flow will close the foramen ovule over time can lead to a transient (come/go) murmur Immediate closure of the ductus arteriosus and ductus venosos
53
Normal NB HR
100-160 Crying or deep sleep can alter values, count for a full minute at the fourth intercostal space and to the left of the midclavicular line
54
Signs of CV dysfunction, what should you do?
tachypnea, tachycardia, pallor, cyanosis, absence of peripheral pulses, poor perfusion Do: Obtain 4 pt blood pressures - if the MAP is below the gestational age it is hypotensive Hypertensive is a MAP between 50-70
55
Blood volume of NB
85 ml/kg at birth 300 ml (if delayed clamping extra 100 ml) Late clamping increases HR, increases systolic, increases respirations
56
Pathologic jaundice
Occurs before 24 hours related to availability of RBCS or RH issues Abnormal destruction of RBC's leads to jaundice
57
Signs of NB sepsis
Low temp, decreased WBCS, pallor
58
Thermoregulation in NB
maintaining balance - not losing heat or producing heat 97.8-98.8 use clinical judgement for higher temps At risk for loss r/t less adipose tissue, vessels close to skin, large surface area to body weight
59
Convection - Heat loss
Losing heat to cooler air
60
Radiation - heat loss
Loss of heat due to cooler surface that is not in direct contact
61
Evaporation - heat loss
Losing heat turning liquid to vapor (sweating)
62
Conduction - Heat loss
Loss of heat bc of contact with a cooler surface
63
NB thermogenesis
Generating heat by increasing muscle activity, crying/restless
64
Brown fat
Unique to NB, richer vascular and nerve supply that increases heat production, located over important organs
65
NB cold stress
Respirations increase, burning glucose in the blood, increases risk of acidosis and hyperbilirubinemia
66
Hyperthermia
Skin vessels dilate, flushed skin, warm to touch, extension of limbs Septic hyperthermia: constricted, pale, hands/feet cold
67
Red Brick Staining
uric acid crystals in urine that can look like blood
68
When should babies first void
Most void within 30 hours if not before 48 consider renal impairment
69
Daily fluid requirements
First 2 days: 40-60 mL/kg Then: 100-150 ml/kg 75% of body weight is water 40% of body weight is extracellular
70
Loss of fluid after birth
Baby should lose 5-10% of birth weight in the first 3-5 days then regain that by day 14
71
Epstein perals
White cysts present in the gums of NB, retention cysts
72
Stomach capasity of NB
30-90 ml, avoid over feeding
73
When should baby pass meconium what is it composed of
Within 24 hours of life has amitotic fluid, intestinal secretions and cells
74
Blood sugar of NB and signs of hypoglycemia
40-80 Jitters, tremors, irregular RR, difficulty feeding, lethargy, apnea, cyanosis

81
cephalhematoma
collection of blood between skull bone and periosteum that does not cross the suture line
82
NB vision
React to light, track objects, 12 inches of vision and prefer patterns
83
Pain in neonate
Increased RR and HR, shallow respirations, pallor, dilated pupils, grimacing ,eye squeezing, quivering of tongue, open mouth
84
Maternal adjustment - taking in
self focus, relies on other for needs, exited, relives the birth experience
85
Taking hold - maternal adjustment
focus on baby, taking charge, eager to learn and practice, still needs help from others
86
Letting go = maternal adjustment
forward as fmaily unit, resuming individual roles, resuming relationship with partner including sexual intimacy
87
Breast feeding contraindications
HIV, TB, HSV on breasts, galactosemia in NB, humal t-cell, chemo in mom and radioactive isotopes
88
mL for babies
20-40 mL/kg (until day 2) 100-140 mL/kg
89
protein values needed for nb
2.25-4g/kg/day
90
fat values needed for nb
5-7g/kg 15% of calories must come from fat corn oil is fat in formula
91
what produces the milk in breasts
alveoli
92
what are the alveoli surrounded by
myoepithelial cells - that contact the milk and send it inot the ductules
