●● D10 Bolus.
Answer: 2mL/kg
●● Fluid Volume Bolus.
Answer: 10mL/kg
●● Term Parenteral Fluid Requirement.
Answer: 80mL/kg/day
Enteral 100-150 mlk/kg/day
●● Preterm Parenteral Fluid Requirement.
Answer: 120
Enteral 150-200ml/kig/day
●● GIR Calculation.
Answer: (%dextrose x IV rate) / (6 x wt in kg)
,●● I/T ratio.
Answer: %Metas + Bands / %Metas + Bands + Segs
I/T ratio greater than >0.2 to >.25 suggestive of infection
>0.8 associated with shock
●● Absolute Neutrophil COUNT.
Answer: WBC x (%) Segmented neutrophils + band neutrophils +
metamyelocytes
Example. 15,000 x 35 segs + 15 bands + 3 metas (turns into percent)
15,000 x .53 = 7950
ANC <1800 suggestive of infection
Normal Range
●● Mature WBCs.
Answer: Poly, Segs, Neutrophils
●● Immature WBCs.
Answer: Meta, Bands, Stabs
,●● Platelet Range.
Answer: 150-400k
Thrombocytopenia (< 100,000/mm 3 ): possible association with
bacterial sepsis or viral infection, but usual onset does not occur until 1
to 3 days after infection onset (late indicator). May also occur with
maternal HELLP syndrome ( h emolysis, e levated l iver function test
results, and l ow p latelet count), pregnancy-induced hypertension, and
intrauterine growth restriction, as well as some syndromes such as
trisomies 13, 18, and 21, Turner's syndrome, and hemolytic disease.
●● CRP level.
Answer: CRP level usually <1.6 for the first two days of life
Elevated cord blood CRP levels are associated with chorioamnionitis
with prolonged rupture of membranes.
●● Most common pathogens.
Answer: Currently, GBS
E. coli
●● Candidas.
Answer: -Diaper dermatitis presents with intense erythema and satellite
lesions.
, -Congenital candidiasis presents with widespread erythematous
maculopapular rash, and preterm infants may present with pneumonia.
●● Congenital CMV infection.
Answer: congenital infection include: intrauterine growth restriction,
hepatosplenomegaly, jaundice, purpura, pneumonitis, microcephaly,
hydrocephalus, intracerebral calcifications, hearing loss, chorioretinitis,
and optic atrophy.
●● Endotracheal Measurement.
Answer: 6 + wt in kg
Proper placement on an endotracheal tube is midway between the
thoracic inlet and the carina.
●● Polyethelane Wrap for Infant < 29 weeks.
Answer: Dry infants head only
Place infant in bag, from neck down
Remove bag once infant is in an NTE and humidified environment
●● UAC Placement.
Answer: High Placement T6-T9
