1
Q
Fetal fibronectin
A
- “high positive indicator”
- If its negative you are not in labour, if its positive you may do into labour in 24hrs
2
Q
ABX in PTL
A
- GBS + or unknown
- maternal fever
- chorioanyitis
- ROM > 12hrs
3
Q
tocolytics
A
- indocid ( > 28wks)
- nifetapine
4
Q
normal fetal preterm HR
A
160ish as sympathetic nervous system develops before parasympathetic
5
Q
normal fetal HR for term
A
140ish
6
Q
consideration for mg in pre-eclampsia
A
- foley
- maintain TFI at 124ml/hr (ie subtract mg does from 125ml/hr)
7
Q
definition of fetal bradycardia
A
HR < 110bpm for > 10min
8
Q
what is indomethacin
A
- NSAID
- Inhibits prostiglandin, which inhibits inflammation ( IE labour)
- indicated in PTL @ 28-32wks
- early use can cause closure of DA and increase risk of NEC
- onset 20 ish mins lasts 2 ish 2hrs, delays labour for approx 48hrs slowing for transfer and steroids
9
Q
Nifedipine (Adalat)
A
- CCB ( blocks calcium influx causing contractions)
- Fist choice tocoyltic as it has less complications
- onset 20 ish mins lasts 2 ish 2hrs, delays labour for approx 48hrs slowing for transfer and steroids
10
Q
gestational hypertension
A
- new onset > SBP 140 OR DBP 90 after 20wks
- absent proteinuria, severe HTN or signs of end-organ damage
11
Q
Severe geststaional hypertension
A
> 160/110
12
Q
Preeclampsia
A
- Proteinuria, thrombocytopenia, or elevated liver enzymes
13
Q
when are antenatal steroids given
A
- risk of delivery with 7 days
- less than 34wks
14
Q
pre-eclampsia management
A
- Nifedipine/labetalol/hydralazine, magnesium, betamethasone target < 160/110
- MgSO4 4g over 20 minutes followed by 1g/hr as a continuous infusion (seizure prophlaxis)
- Glucocorticoid course (betamethasone) for women with a viable preterm fetus (23+0 to 34+6) and preeclampsia
- Consider platelets
15
Q
eclampsia
A
new onset seizures in pregnancy or up to 1wk postpardum
