NOT IVH/PVL, NOT CP
ID: Required to chart mom positive in baby chart
- HIV
- HEP B
- GBS
- Syphilis
HIV: Transmission Incidence
<1% w <1,000 copies/ml viral load
GBS: Transmission Route
- L/D most common
- in utero –> stillbirth
HIV: Risk Factors
- STI <12m
- IV drug use or partner
- new sex partner, >1 partner preg
- partner HIV or high risk
- care in hospital high incidence HIV
- location high incidence HIV
- Incarceration
- s/s HIV infection
HIV: Screening
- PNC - opt out antigen/antibody test T1, repeat T3 <36wk high risk
- Unknown prepartum - rapid HIV (confirm test, asap ART)
- Unknown postpartum or positive maternal - infant DNA
HIV: Delivery Implications
- >1,000 copies/ml or unknown w/o labor AND w/o ROM - c/s 38wk, IV zidovudine 3hr preop
- >1,000 copies/ml or unknown w labor OR ROM - no consensus
HIV: Transmission Route
L/D
HEP B: Transmission Incidence
- <1% transmission HBsAg positive w tx
- 30% transmission HBsAg positive w/o tx
- 85% transmission HBeAg positive w/o tx
HEP B: Risk Factors
- STI >12m
- IV drug use or partner
- new sex partner, >1 partner preg
- partner HIV or high risk
- care hospital high incidence HEP B
- location high incidence HEP B
- incarceration
- s/s HIV infection
HEP B: Screening
- T1 - HBsAg screen
- if positive - screen HBeAg, Hep B virus DNA, alanine aminotransferase, refer GI, repeat T3
- T3 or L/D repeat positive or high risk
HEP B: Vaccine
- HBsAg positive
- HBIG (HEP B immunoglobulin), HEP B <12hr
- HBsAg unknown
- HBIG <12hr
- <2,000g - HEP B <12hr
- >2,000g - HEP B <7d or d/c
- HBsAg negative
- <2,000g - HEP B 1m or d/c
