Do not take rectal temps as bowel sphincter can cause rectal prolapse
What is meningocele spina bifida
Hernial protusion of a sac like syst filled with meninges and spinal fluid that is visible on the outside of the spinal cord
What is myelomeningocele spina bifida

What is Neonatal sepsis?
A blood infection that occurs in newborns (<28 days).
Why do newborns have increased susceptibility to infection?
Due to their diminished inflammatory and humoral immunity. This causes decreased or no inflammatory response to signal that there is an infection.
What is early onset neonatal sepsis?
Occurs within the first 3 days, and is typically acquired during labor from mom.
What is the most common bacteria that causes early onsite neonatal sepsis?
GBS
What are other bacteria causes of early onset neonatal sepsis
E.Coli, listeria
What are some complications that can be caused if neonatal sepsis is left untreated?
Neuro and respiratory problems
What is late onset neonatal sepsis?
Sepsis that occurs 4 days or later after birth.
What are some different bacteria that cause late onset neonatal sepsis?
Staphyicocci, e. coli or candida
From: skin, mucous membranes, or umbilical stump
How does pregnancy cause neonatal sepsis?
from maternal bloodstream to placenta (CMV, toxo lasmosis)
How does labor cause neonatal sepsis?
passes infection from mom to baby in the birth canal
What are causes postnatally of neonatal sepsis?
invasive devises, cross contamination with other babies or people, prolonged ROM, preterm, traumatic / difficult labor
What are s/s of neonatal sepsis ?
-Body temp changes
-irregular respirations
-Reduced sucking, grunting, retractions
-lethargy, irritability
-Abdominal distention, vomiting
-jaundice, pallor, cyanosis
How do you diagnose neonatal sepsis?
-Early recognition of s/s
-definitive DX: Blood culture, urine culture, CSF
How can we prevent neonatal sepsis ?
-GBS testing at 36 weeks
-If (+), Abx and potential C-section
-HepB + HIV screening (passed through breastmilk)
-Early recognition
-Abx therapy BEFORE lab results are confirmed and organism is identified
-Respiratory support
-VS monitoring, fluid regulation
-thermoregulation
What are treatment options for neonatal sepsis?
-Antibiotics
-potential blood transfusion for anemia
(+) organism screening needs Abx for 7-10 days
(-) organism screening, discontinue abx 48 - 72 days
What is PKU (Phenylketonuria) ?
A rare genetic disorder where babies lack the enzyme needed to breakdown phenylalanine into tyrosine
What does a build up of phenylketonuria lead to?
neuro and cognitive impairment as the body will excrete an abnormal amount of phenylaetic acid.
what are the S/S of PKU?
-Failure to thrive
-Vomiting, irritability, convulsions
-Hyperactivity, erratic behavior problems
-Older children can experience bizarre, schizoid behavior (due to decrease in dopamine and serotonin)
-musty odor (due to increase uric acid)
-lighter skin (due to decreased tyrosine (makes melanin)
-heart defects
-seizures
How do you diagnose PKU
newborn blood tests on baby (PKU test)
screen mom before pregnancy
Key: test after 24 hours old and after baby has ingested protein
That is the treatment for PKU?
Diet: limited intake of protein
PKU Formula: gived you protein that does not have phenylalanine
Watch amount of protein eaten (milk, eggs, cheese, meat, poultry, fish)
What should moms with PKU while they are pregnant, but what are the risks?
PKU moms should follow a PKU diet
Risk: microcephaly, cognitive impairment, heart defects, mother could suffer miscarriage.
What is neonatal jaundice?
yellow discoloration of a newborns eyes and skin due to excess bilirubin in the blood
What is bilirubin?
a substance that is produced and released with the breakdown of RBCs in the liver. It travels from the liver and is stored in the bile duct and expelled in the stool
What causes jaundice?
newborns produce more bilirubin than adults and their liver cannot break it down fast enough.
what are other causes of jaundice?
internal bleeding
infection / sepsis
Rh incompatibility
Biliary Atresia
Liver disfunction
What are the different types of neonatal jaundice?
Pathologic
Physiologic
Prolonged
What is Pathologic jaundice
Not normal
Onset: first 24 hours
Cause: Sepsis or decrease in blood (ABO, Rh incompatibility)
What is physiologic jaundice
Very common
Onset: 2-14 days
Cause: Immature liver has a tough time breaking down RBC and handling lots of bili
What is prolonged jaundice?
Further testing is needed
onset: >14 days *may last 4-5 weeks
Cause: may indicate an underlying condition such as hypothyroidism, biliary atresia, cystic fibrosis
What are the S/S of neonatal jaundice?
-#1; jaundice skin and sclara
-poor feeding
-not gaining weight
-high pitch cry
-lethargic
-pale stools
How to diagnose neonatal jaundice
-presenting symptoms
-bilirubin level in blood
-LFT’s torch screen -> look for underlying issue
What is a normal Bilirubin level?
<5 mg/ dl
What are treatment options for neonatal sepsis?
-phototherapy
-nutrition (more frequent feedings, breastfeeding)
-transfusion (if there was a blood incompatibility with mom)
*1st IVIg Transfusion
*2nd blood transfusion
What is a Febrile Seizure?
Seizure that is triggered by increased temperature
6mo to 5 year
What do febrile seizures happen?
Cause is unsure:
-fever increases core temp -> neurons become excited
-fever causes hyperventilation, which lowers CO2in blood (leading to resp alkalosis increase blood ph), neurons get excited
-Fever is caused by cytokines that get released by WBCs during antibodies immune response.
What are risk factors for febrile seizures?
-6 mo - 5 years (majority 12-18 mo)
-rapidly developed fever
-high fever number
-certain vaccines that stimulate the immune system (MMR)
-Family HX of febrile seizures
-the younger the age at onset, the increase risk of reoccurring episodes
What are S/s of febrile seizures
-Fever >38 C / 100.4 F
-Simple febrile seizure
*has one seizure in 24 hour span
*affects the entire body
*lasts less than 15 minutes
-complex febrile seizure
*more than one in 24 hours
*affects only one part of the body or one side
*lasts longer than 15 minutes
What are manifestations of febrile seizure
-flutter eyelids or roll eyes
-stiffen, jerk or twitch muscles
-clench jaw, lose bladder function
-lose consciousness (post ictal state)
Treatment for febrile seizures
ground and side laying position
antipyretics
antiseizure
distinguish fever from other causes (meningitis, encephalitis)
