rhogam dose =< 12w
50-120mcg
rhogam dose >12w
125-300mcg
most common gene mutation causing thrombophilia in preg
Factor V Leiden heterozygous
criteria for positive CST
late decels following 50% or more of ctx (even if not enough ctx)
unsatisfactory CST
fewer than 3 ctx in 10min or uninterpretable tracing
equivocal-suspicious CST
intermittent late decels or significant variable decels
equivocal-hyperstimulatory CST
FHT decels in presence of ctx more than q2min or lasting longer than 90s
max daily caffeine intake in preg
200mg
Criteria for adequate CST
At least 3 contractions in 10 minutes
Each contraction is at least 40 seconds in duration
Positive CST
Late decelerations after 50% or more of contractions (even if the contraction frequency is fewer than 3 in 10 minutes)
Equivocal-suspicious CST
Intermittent late decelerations or significant variable decelerations
Equivocal CST
FHR decelerations that occur in the presence of contractions more frequent than every 2 minutes or lasting longer than 90 seconds
Unsatisfactory CST
Fewer than 3 contractions in 10 minutes or an uninterpretable tracing
EFM reduces the risk of…
Neonatal seizures
subgaleal hemorrhage vs cephalohematoma
cephalohematoma = “fenced-in” blood between skull bone and periosteum (dense overlying conncective tissues)
Vs subgaleal bleeding = unrestricted (crosses suture lines) bleeding in the loose tissue between aponeurosis (galea aponeurotica) adn periosteum (LIFE THREATENING)
Fetal head hemorrhage that crosses suture lines
subgaleal hemorrhage
gestational sac on TVUS at
4.5-5wk
yolk sac at

diagnostic of pregnancy failure on US
- CRL >=7mm and no FHT
- mean sac diameter >= 25mm and no embryo
- US with GS & yolk sac > 11d later embryo without FHT
- US with GS & NO yolk sac > 14d later embryo without FHT
suspicion of pregnancy failure on US
- CRL <7mm and no FHT
- mean sac diameter 16-24mm and no embryo
- US with GS & NO yolk sac > 7-13d later embryo without FHT
- US with GS & yolk sac > 7-10d later embryo without FHT
- absence embryo >= 6w from LMP
- empty amnion (+YS) without embryo
- enlarged yolk sac (>7mm)
- small gestational sac in relation to size of embryo (<5mm difference between mean sac diameter and CRL)
