127
What are some of the factors that contribute to hyperbilirubinemia?
- Hemolysis of excessive RBC - Short RBC life - Liver immaturity (liver is what processes bilirubin) - Lack of intestinal flora - Delayed feeding (unable to pass their meconium) Fatty acids from cold stress or asphyxia ( FA displace bilirubin- and it is unable to bind to albumin as well). -trauma resulting in bruising or bleeding ie. cephalohematoma - build up of RBC
128
What are the 8 key checklist items that are required to evaluate / assess a baby for risk of hyperbilirubinemia?
- Was the baby premature - Did the baby experience birth trauma or bruising? Is the baby of Asian or Indigenous ethnicity? - Did the baby's siblings have newborn jaundice? - Is the baby being exclusively or partially breastfed? Are fewer than 6 diapers saturated w/ urine each day ? dehydration >> prevents urobilin - Is the baby a boy? - Is the mother Rh negative or blood type O
129
Why is breastfeeding so important to prevent hyperbilirubinemia ?
breastfeeding should be started within the first hour, and then infant should be fed 8-12 times within the first 24 hours. colostrum is a laxative which promotes stooling and helps the baby pass meconium
130
What is the best therapy for hyperbilirubinemia?
Prevention
131
What is the TCB (transcutaneous bilirubin screening) tool used for?
It is measuring the amount of bilirubin via light refraction. placed on the sternum of the newborn. 3 measurements are taken TcB can reduce the need for a blood serum test TSB . more accurate at lower levels and no longer accurate once phototherapy is initiated.
132
What would we check if the mother is Rh negative or Type O ?
DAT (direct antiglobulin test). Which checks to see if there are antibodies that can cause hemolytic disease of the newborn. DAT is used to determine whether the newborn RBCs have been attacked by the mother's antibodies. DAT is also referred to as a Coombs test.
133
what is the purpose of phototherapy?
used to reduce the amount of circulating unconjugated bilirubin. It uses blue wavelengths to change the shape of unconjugated bilirubin so it is more easily excreted
134
physiologic jaundice peaks at what days?
days 3-5
135
Why are newborns at higher risk of thermal dysregulation
Thin layer of subcutaneous fat and blood vessels are close to the surface of their skin newborns have brown fat reserve
136
What will happen physiologically if the newborn is cold?
They will cry and wiggle to try and generate heat (thermogenesis) increase in cellular metabolism which increases oxygen and glucose demand newborn will assume the position of flexion >> to decrease heat
137
Newborns typically do not shiver, what do they do to warm themselves?
non-shivering thermogenesis, metabolize their brown fat supply. reserves of brown fat are quickly depleted with cold-stress. Also term infants have greater stores of brown fat than preterm infants.
138
Is heat lost or gained? 1. Baby’s naked, dried body is placed on mom, skin-to-skin 2. Warm, wet newborn covered with amniotic fluid is delivered 3. Baby is removed from incubator for a procedure 4. Baby is placed in an incubator with warm, circulating air 5. Baby is bathed 6. Baby is placed near a cold exterior wall 7. A cool stethoscope is used when determining the newborn’s heart rate
1. Gained - best if covered with a blanket 2. Heat loss – evaporation 3. Convection - heat loss 4. Heat Gain - convection 5. Evaporation – heat loss 6. Radiation – heat loss 7. Conduction- heat loss `
139
How is non-shivering thermogenesis triggered?
Usually triggered at a mean skin temperature of 35-36° C ↓ Thermal receptors in the skin perceive a drop in environmental temperature and transmit impulses to the hypothalamus ↓ Stimulates the sympathetic nervous system ↓ Release of norepinephrine ↓ Stimulates brown fat metabolism by the breakdown of triglycerides ↓ Generates heat ↓ Increases body temperature
140
What are the physiological adaptations that occur when the newborn experiences cold stress?
``` Peripheral vasoconstriction less activity, lethargy, hypotonia depleted brown fat stores respiratory distress Metabolic acidosis >> kidneys are unable to remove acid Hypoglycemia ```
141
What are the differing displays of hyperthermia in a newborn for external vs internal sources?
External source (too many blankets): flushed skin, hands and feet warm to touch, posture of extension Internal source (d/t sepsis): pale from vasoconstriction, hands and feet are cool
142
When does the newborn experience the peaks of hypoglycemia post birth?
30-90 minutes after the cord is cut we want to see newborns glucose stabilize within the first 3 hours of life 2.5-3mmol/L and by the third day should be between 4-5mmol/L
143
“The _______ period begins after the delivery of the placenta and lasts approximately 8 weeks.
puerperium
144

146
What causes significant drops in insulin of the mother directly after birth
decrease in hPL a type diabetic mother will need less insulin HCG disappear from the maternal system pretty quickly after birth
147
What impacts a womans serum prolactin levels?
How frequently and much she breast feeds How long breastfeeding goes for woman who doesn't breastfeed, prolactin levels decrease rapidly and return to pre-pregnancy levels in 3 weeks
148
What changes occur to menstruation after birth
woman who is not breastfeeding, menstruation will return within 27 days after birth woman who is breastfeeding it will return in about 6 months
149

254
How do you tell the difference btw syncope and anaphylaxis
Fainting: vasovagal syncope >> typically anxious and hyperventilating Breath holding typically happens in very young children. upset and crying will become silent. may faint but start to breath again once they pass out. SYNCOPE: occurs within seconds/minutes, pale nausea, dizzy, ringing in ears, blurred vision, sweating, rhythmic jerking in limbs, can become unconscious in a few minutes, place in recumbent position. ANAPHYLAXIS: Develops over several mins, usually involves 2 body systems, pt does not pass out immediately, >> treatment = epinephrine
255
steps for basic management of anaphylaxis in a non-hospital setting.
1. Assess circulation, airway, breathing, mental status, skin, and body weight (mass). Secure an oral airway if necessary. Direct someone to call 911(where available) or emergency medical services. 2. Position the vaccine recipient on their back or in a position of comfort if there is respiratory distress; elevate the lower extremities. Place the vaccinee on their side if vomiting or unconscious. 3. Inject epinephrine intramuscularly in the mid-anterolateral aspect of the thigh: 0.01 mg/kg body weight of 1:1000 (1 mg/mL) solution ADOLESCENT or ADULT: maximum - 0.5 mg CHILD: maximum - 0.3 mg Record the time of the dose. Repeat every 5 to 15 minutes as needed, for a maximum of three doses 4. Stabilize vaccinee; perform cardiopulmonary resuscitation if necessary, give oxygen and establish intravenous access if available and give adjunctive treatment (i.e. diphenhydramine hydrochloride or Benadryl®) if indicated. 5. Monitor vaccinee's blood pressure, cardiac rate and function, and respiratory status. 6. Transfer to hospital for observation. ** helpful if you can have someone writing this all down. Need the time for when the epinephrine was administered.
256
Important things to remember when giving a vaccine:
No gloves are required Aspiration for blood return in not required Z-tracking is Not required. Cannot pre-load syringes, doses need to be prepared just before administration cold-chain needs to be maintained always check the basics: expiration date, cloudy vs clear solution,
257
