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)
