Q

Newborn baby, a few hours old, is cyanotic. You suspect cyanotic heart disease but you don’t have access to an echo at the community hospital you’re working at.

a) Aside from an EKG and CXR, what are two tests that you could do to confirm cyanotic heart disease?
b) What treatment would you start while awaiting the transport team?

A

a) HyperO2 test
Pre- and post-ductal sats
4 limb BP
Physical exam

b) O2, manage BP
* Prostin (TAPVR with obstruction may get worse = more blood flow to lungs that cant get back)

Q

You are taking care of a newborn ventilated baby born at 26 weeks who is now 29 weeks CGA with pulmonary interstitial emphysema on CXR. He is currently ventilated with the following settings: rate 40, PIP 18, PEEP 4, 60% O2. You receive the following blood gas: pH 7.20, pCO2 58, pO2 56, HCO3 19, base deficit -6.
a. What change in ventilator settings do you make?
b. 48 hours later the baby is suddenly mottled, and has the following bloodwork: Na 139, K6.8, pH 7.18, pCO2 38, pO2 68, HCO3 12, base deficit -12. The baby’s urine output is 2.5 cc/kg/hr. What complication has most
likely occurred?

A

a. increase rate (best strategy for ventilation in PIE is permissive hypercapnia since escalating support can worsen PIE - increase rate over pressures to control ventilation)
b. Metabolic acidosis from poor cardiac output from bad PIE or pneumothorax

Q

A term baby was born following an uncomplicated pregnancy to a healthy mother. The delivery was complicated by decelerations.

b) 1
c) 2
d) 3

A

Stage 1

Q

Newborn weighs 1.8 kg. Jittery and found to have glucose 1.3. Repeat glucose is 0.8 What is this baby’s glucose requirement in mg/kg/min (1)?. Write your IV order (1)

A
  1. GIR = 5.5mg/kg/min
  2. bolus 2cc/kg of D10W IV over 5 minutes, then run D10W at TFI of 80ml/kg/day

Calculating Fluids from GIR:
D10W = 10 g dextrose/100 mL = 100 mg/mL

For D10W —> X mg/kg/min (1 ml/100 mg)(60 min/hr)(weight)

Fluids = GIR (ml/kg/min) x 0.6 x weight

Calculating GIR from Fluids
For D10W —> X ml/hr (100 mg/mL)(1hr/60min)(1/weight)
GIR = Fluids (ml/kg/hr) x 1.6666667

A

e) prostaglandins

In neonates with severe coarctation of the aorta, closure of the ductus often results in hypoperfusion, acidosis, and rapid deterioration. These patients should be given an infusion of prostaglandin E1 to reopen the ductus and re-establish adequate lower limb blood flow.

A newborn term infant had thin meconium at delivery but had good APGAR scores and required only 2 minutes of free flow O2. Now at 12 hours of age he has increasing
work of breathing. On CXR there is hyperinflation of the RUL with mediastinal shift. What is the most likely diagnosis:

CXR - radiolucent lobe and mediastinal shift.

Q

BB born at 28 weeks now 9 weeks old-do you give iron and why

A

Babies born premature are at risk for earlier, more severe nadir in hemoglobin level as they have reduced iron stores. Iron stores are transferred from mom to baby in the third trimester, and if born early this has not likely happened fully. Iron is important for generation of red blood cells and in this period, very important for maximizing developmental potential.

accounts for 70% neonatal Hgb, declines to <2% by 6-12 months

HbA2 = 2 alpha and 2 delta
Normal variant of Hgb A
<1% of Hgb at birth, but rises to adult levels (2.0 to 3.4%) by 1 year. Increased in beta-thalassemia. Normal in sickle cell

HbS = 2 alpha, and a sickle-beta is present. Normally, there is no hemoglobin S

A

a. feed and recheck BS in 1 hour

194
Q

6 week brought in with umbilical mass, present since stump separation at 10 days.

3 things on Ddx
Management plan for each

A

Umbilical granuloma - silver nitrate 1-2 x per week

Umbilical polyp - mesenteric duct remnant - surgical excision
Ectopic tissue (pancreas or liver) - surgical excision.
195
Q

Unstable premature neonate on Ventilator with ++02 needs. Desating frequently with handling and recovering with bagging. What do you do?

d) Increase sedation
e) Steroids
f) surfactant
a) Minimize handling, increase sedation

A

a) Minimize handling, increase sedation
- suspect PPHN - labile sats that recover well with bagging

? Could also consider surfactant depending on the age of the baby (first 72 hours)

196
Q 
3 day infant cyanosis with crying, investigation
a ECG 
b CXR
c ABG 
d bld cx 
e echo
A

e echo

- crying increases right sided pressure which increases right to left shunting (and therefore increases cyanosis)

197
Q

1 mo 2 day old with a vesicle noted on the upper lip?

a. Sucking blister
b. HSV
c. Varicella
d. Epidermolysis bullosa

A

a. Sucking blister
- Sucking Pads
o Calluses/vesicles found on lips in first few months
o Confirmed by observing neonate sucking the affected area

198
Q

Child with cyanosis, O2 sat 80% doesn’t improve with oxygen. Pan systolic murmur grade III/IV. CXR normal and ECG shows right axis deviation. What is the diagnosis?

A

Some kind of CHD with R -> L shunting.

Babies all have RAD.

?TOF (boot shape)
?TGA (egg on string)
Tricuspid Atresia
Pulm Stenosis
?If pulm pressures high still ASD R->L could do this too
199
Q

An infant born at 26 weeks gestation is now 28 weeks (2 weeks old). He is doing well and is going to be transferred to a level II nursery. When should he be screened for ROP.

a) if normal now, no need to do further follow-up
b) do eye exam now
c) do eye exam at 32 weeks
d) do eye exam at 38 weeks
e) do eye exam at 52 weeks

A

c) do eye exam at 32 weeks
- if born at less than 28 weeks, screen at 31 weeks CGA, if born at 28+ weeks, screen at 4 weeks of life

CPS suggests screening all infants born before 31 weeks GA, or <1250 g, or older with risk factors. Screen at 4 weeks of age or 31 weeks CGA, whichever is later. No infants found to have ROP prior to 31 weeks CGA!

Q

a. start thyroxine
b. repeat neonatal screen
c. bring them into the office as soon as possible
d. thyroid ultrasound

A

c. bring them into the office as soon as possible

201
Q

Term male, delivered by emergency C-section for fetal distress. Meconium present, suctioned below cords. Now needing 100% O2. Radial Gas PaO2 80. Umbilical gas
PaO2 40. What is the diagnosis?

a) PPHN
b) Meconium aspiration
c) TGA

A

a) PPHN

  • PPHN should be suspected in all infants with cyanosis
  • hypoxemia is present in all cases
  • intermittently unresponsive to 100% O2
  • oxygen saturation or PAO2 gradient between preductal (right radial artery) and post ductal (umbilical artery) sites of sampling imply shunting across PDA

A

d) Hydronephrosis

A

b) Wilm’s tumour

Beckwith-Wiedemann

  • Overgrowth syndrome
  • 15% familial, 85% sporadic

Hallmark: omphalocele, macroglossia, macrossomia, neonatal hypoglycemia

a) hypernatremic dehydration due to decreased fluid intake
b) hypertonic breast milk
c) diabetes insipidus
d) sepsis
e) meningitis

A

d) sepsis

206
Q

- mgmt: platelet transfusion with maternal washed platelets or HPA1a (PLA1) negative platelets

207
Q
