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

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

Which is true of ophthalmia neonatorum a) The most common organism is Neisseria Gonorrhea, but it is now almost always resistant to the prophylaxis, therefore prophylaxis is not indicated b) Ophthalmia neonatorum can lead to significant eye injuries and blindness, therefore antibiotic prophylaxis is indicated c) The most efficient way of preventing it is through screening and treatment of pregnant women rather than the current prophylaxis.
The most efficient way of preventing it is through screening and treatment of pregnant women rather than the current prophylaxis. We screen at first prenatal visit, do a test of cure, and repeat in 3rd trimester.

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

A term infant was the product of an uncomplicated pregnancy to a healthy mother with protective serologies, normal ultrasounds, and routine prenatal care. The delivery was marked by a slow 2nd stage due to cephalopelvic disproportion. A shoulder dystocia required multiple maneuvers to extract the baby. He was born vigorous, without need for resuscitation, but the obstetricians are concerned that he may have an Erb’s palsy. Should that be the case, what are you likely to find on your physical exam? a) Presence of a grasping reflex in the affected limb b) Presence of a symmetric Moro reflex c) Presence of brachial deep tendon reflexes in the affected limb d) Significant swelling of the affected limb
a) Presence of grasping reflex in affected limb Erb's palsy: - areflexive or hyporeflexive in involved arm - grasp usually intact - asymmetric moro - affected arm atrophy - limb may be cool
