- Uses both clinical indicators and lab findings for scoring (20 lab, 35 clinical) max 55
- CBC with diff
- WBC
- Total neutrophils
- ANC
- platelet count
- ABG
- pH - if acidotic
- CBC with diff
- A score < 10:
- Healthy
- no sepsis
- A score > 10
- “sick baby”→ further diagnostic eval
17
Q
Neonatal Sepsis: Diagnostic Evaluation
A
- Gold standard: Blood, Urine, and CSF cultures
- CRP, PCT levels
- CXR, and films, joint x rays
- **There is no laboratory test that is 100% sensitive or 100% specific for sepsis. Normal results do not rule out infection or sepsis in the newborn.
18
Q
Group B strep prophylaxis
A
Treat prophylactically 4 hrs prior to birth and every 4 hrs until delivery if mom has + culture or history of positive
19
Q
Group B risk factors
A
- premature (< 37 wks)
- SGA
- Low APGAR
- ROM > 18 hrs - increase of chorionitis
- Maternal fever
- Prior infant with group b strep
20
Q
onset of GBS (early, late, late late)
A
- Early- onset GBS
- Within first 7 days of life
- 98% asx
- Late-onset GBS
- 1 - 3 months
- bacteremia, meningitis, bone infxn
- Late, late-onset GBS
- > 3 months of age and older
- More likely in NB born < 28 wks gestation or immune deficient
21
Q
positive or unknown GBS status of mother laboring:
A
at onset of labor, give IV penicillin then ampicillin then every 4 hours until baby is born.
if c section before ROM, don’t need antibiotics bc intact amniotic membranes
22
Q
GBS diagnostics
A
- same as sepsis
- culture
23
Q
antepartum tx of asymptomatic GBS positive mothers
A
NOT RECOMMENDED
get IV penicillin or ampicillin onset labor, q 4 hrs til born except during c section before ROM
24
neonatal abstinence syndrome (NAS) onset
Usually within 2-3 days but can be delayed up to 28 days depending on ½ life of substance and last dose
25
NAS sx/s
* may persists 4-6 months after birth
* High pitched cry
* Irritability
* Trouble sleeping
* Seizures
* Hypertonia
* Present up to 72 hrs - 28 days and sx’s persist up to 6 months
* **Premature infants have immature neuro so less likely to experience NAS**
26
mothers and prenatal substance
* **All mothers should be assessed for prenatal substance use-universally, every patient, every visit**
27
NAS: Symptoms and Diagnostics
* Signs reflect dysfunction in any of 4 domains:
* state control and attention
* motor and tone control
* sensory integration
* autonomic functioning
* Diagnostics on infant:
* Urine - detects 30 days
* Alcohol few hrs after last use
* Cocaine - 1-3 days after last use
* Opioids 2-4 days
* Weed - 1 month after last use
* Meconium & hair samples
* Collect first 48 hrs of life
* Can detect from 20 weeks on in pregnancy
* Mother’s report
* Consent issues
* Report to Child protection if present
28
what tool to use to assess NAS and guide treatment
* “Modified Finnegan Score”
* score of \< 8 = no withdrawal
* assess infant 2 hrs after birth then q 4 hrs
* include caregiver
29
ESC Tool & Non pharm management
* Eating, Sleeping, Consoling Care
* Tx of NAS - supportive care
* focuses on infant function and comfort rather than reducing the signs and symptoms of withdrawal.
* Performed q 3-4 hours for first 4-7 days of life
* Non-pharmacologic management:
* 4 “S”- shush, suck, swing, swaddle
* Calm environment
* Rooming in
* Skin to skin
* If ^ doesn’t help, med considered
30
NAS pharm therapy
* if non pharm doesn't work
* Aimed at the short-term improvement of clinical symptoms
* Drug chosen from SAME class that was exposed to, then gradually weaned
* Ie: first line opioid w/drawal: morphine, methadone
* 2nd line: clonidine or phenobarbital
* Risks to consider before starting medications to treat NAS
* Longer length of stay
* Reinforce discomfort should be medicated
30
NAS Discharge and Follow up considerations
* Monitor in hospital until symptoms managed and weaned from narcotic meds
* Close follow up → risk for neurodevelopmental concerns and to monitor social situation
* Stable home environment (substance use at home)
31
Chlamydia: conjunctivitis
* Mild swelling to blood discharge with erythema eyes
* **presents in 5-14 days**
* mucopurulent eye exudate and eye swelling
* Dx: NAAT - swab nasopharyngeal and conjunctiva swabs
* exposure during delivery
32
staccato cough
* inspiration/breath between each single cough
* from Chlamydia pneumonia
* Nasal congestion
* Crackles / rales
* CBC - eosinophilia
* CXR: hyperinflation with bilateral, symmetrical interstitial infiltrates
33
chlamydia In NB treatment
* Treat *both* conjunctivitis and pneumonia with **ORAL** **Erythromycin** x 14 days
* Assess risk for hypertrophic pyloric stenosis in infants \< 6 weeks
* call if projectile vomiting
* NO topical therapy (doesn't work)
* Evaluate for N. Gonorrhoeae
* Educate mom on sx’s of conjunctivitis or pneumonia
34
if mom is chlamydia positive and infant is asymptomatic
* \*\*\*\*\*No prophylaxis treatment is given for an _asymptomatic_ infants with _chlamydia positive mom_
* because risk of pyloric stenosis when give infant erythromycin
* Educate mom on sx’s of conjunctivitis or pneumonia
35
Gonorrheal Ophthalmia neonatorum
sx's & Dx
* Purulent and profuse exudate, swelling of the eyelids within first 5 days of life
* Onset usually 2-5 days after birth
* ulceration, scarring = blindness
* dx: culture and gram stain, consider chlamydia co infection
36
Gonorrhea: Ophthalmia Neonatorum Treatment
* Ceftriaxone 25-50 mg/kg, max 125 mg, IV/IM x 1
* Isolation for 24 hrs
* Evaluate for disseminated gonorrheal infection (DGI)
* Sx: fever , rash, arthritic joint pain
37
Gonorrhea eye prophylaxis
every infant at birth
* 0.5% erythromycin ophthalmic ointment or 1% tetracycline ophthalmic ointment
38
Sudden Infant Death Syndrome
* sudden and unexpected death of an infant \< 1 yr
* cause was not obvious prior to investigation, without any underlying medical problems
* death remains unexplained despite a thorough investigation, including autopsy, death scene investigation, and review of the clinical history.
39
leading cause of death in infants between 1 month and 1 year of age in the United States
SIDS
40
SIDS risk factors
* Any sleeping position besides back
* prone, side
* Soft bedding
* Bed sharing with parents or other siblings.
* Exposure to tobacco smoke
* Premature or low birth weight
* Late or no prenatal care
* Young maternal age
41
SIDS protective factors
* breastfeeding
* Pacifier use → stimulates breathing
* Room sharing for 6-12 months but co sleeping
* Immunizations.
* ceiling fan → cool environment
* The biggest risk reduction we can have is the safe sleep environments
* avoid smoking/alcohol/drug use
42
how to correct gestational age for a premature infant?
ex: born 32 wks gestation, comes in at 16 weeks old
32 weeks - 40 weeks = 8 weeks premature
8 - 16 weeks = 8 weeks/2 months
