NICU - 2019 Updated! Flashcards
(210 cards)
Newborn with persistent bradycardia. ECG given. Looks like heart block… identify the problem. What 2 things is this child at risk for?
- Cardiac arrest/Death
- Syncope

- For infants and toddlers → night terrors, tiredness with frequent naps & irritability
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) 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)
32 Week infant born and mother wants to know when they can take baby home. List 4 physiologic measures of stability that baby must have:
- Themoregulation : maintenance of normal body temp when fully clothed in open cot
- Respiratory stability: maintain sats >90-95 in room air
- Control of Breathing: apnea free period (~5-7 days)
- Feeding Established w/o cardio resp compromise and sustained weight gain
33 weeker with HIE. Bad gas. Apgar at 10 minutes =4. What is the contraindication to cooling?
- Gestational age
- Apgar at 10 minutes
- Gas
- Gestational age
Cooling: For infants who are >36 weeks, < 6 hours old and meet inclusion criteria (basically a bad gas or moderate gas and bad apgars, plus S/S of encephalopathy).
No benefit in <35 weeks
An infant born at 28 weeks of gestation is currently 2 months old (chronological age) and well. He is in your level 2 nursery on supplemental oxygen via low flow nasal cannulae and learning how to feed at the breast and bottle. When will you prescribe his first series of immunizations?

Go by chronological age.
Which of the following is associated with polyhydramnios

Male 3 weeks old. Presents with shock, hyperpigmented scrotum, low NA 115, K 6.8. What is your most important investigation? What is your immediate management?
Concern for CAH
- ABCs - in shock therefore needs IV access and fluid bolus
- hydrocortisone
- Ix: 17-OHP
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. 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
Newborn with trisomy 21, non-bilious vomiting after feeds. What’s the test?
a. Abdominal ultrasound
b. Barium swallow with follow through

Baby born at home. No healthcare contact. Comes in with lethargy and bruising. Elevated PT/PTT.
a) What is likely cause?
b) How much vitamin K should be given at birth?
c) What investigation would you do immediately?
a) Vitamin K Deficiency
b) 0.5 mg IM (if BW < 1500g) or
1. 0 mg (if BW>1500g) IM x1
c) Head US/CT
Oral Dosing:
2mg at birth, repeat at 2-4 weeks and again at 6-8 weeks

d. TOF
a. CoA
37 weeker. Mild lethargy. Total bili 280 @ 30 weeks (?meant hours). No ABO. Give 3 bili charts. Mgt?
a. Follow-up in 24 hours
b. Phototherapy and repeat bili in 6 hours
c. Exchange
d. IVIG
b. Phototherapy and repeat bili in 6 hours
- medium risk line (only significant lethargy counts as a risk factor)
- at/above exchange line; no use for IVIG if no ABO

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)
- GIR = 5.5mg/kg/min
- 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
