monday 9th Flashcards
(43 cards)
When is anti D given?
28 and 34 weeks
When is an USS done in placenta praevia?
32 weeks
what are 4 things looked at on CTG?
baseline rate (110-160 is reassuring)
variaibility (5-25 is reassuring)
accelerations (good)
descelerations (prolonged are bad)
what are the movements of the fetus in labour
descent
engagement
neck flexion
internal rotation
crowning
extension of the presenting part
restitution
external rotation
lateral flexion
what are the two stages of the first stage of labour?
latent (0-3cm)
active (3-10cm)
how is active management of the third stage managed?
IM oxytocin and controlled cord traction- when the placenta is detached there will be lengthening of the umbilical cord, explusion of blood and ascension of the uterus in the abdomen
what are 2 definite indications for active management of the third stage?
haemorrhage or passive management taking over 60 minutes
what are the 5 things considered in bishops scoring and what score indicates induction is needed
cervical effacement
cervical consistency
cervical position
cervical dilation
fetal station
what antibiotics will be given for asymptomatic bacteriuria in the first trimester and in the third trimester
first- nitrofuratoin
third- amoxicilin
what test for syphilis is done at booking appointment
VDRL test
what three things will be assessed in determining the risk of premature birth?
- part history of premature birth
- cervical length on transvaginal USS (if less than 25mm it is likely)
- fetal fibronectin (if <50 then unlikely
what two things can be done to prevent premature birth and why would one be chosen?
- vaginal progesterones
- cervical clerclage
Cervical clerclage will be done if previous premature labour, or if cervical trauma such as cone biopsy
when should someone with gestational diabetes be delivered?
38 weeks
when should someone with obstetric cholestasis be delivered?
37 weeks
what are some indications for induction of labour
post maturity
decreased fetal movements
conditions such as gestational diabetes (38) and obstetric cholestasis (37 weeks)
pre-eclampsia
fetal death
PPROM
What bishops score needs induction of labour ?
5 or below
what are 4 methods that will be used in induction of labour
Membrane sweep
Vaginal prostoglandins E2
Balloon catheter
Amniotomy and IM syntocinon
what is the main complication of induction of labour and what would it be characterised?
uterine hyperstimulation (indicated by >5 contractions in 10 mins)
what defines miscarriage, what is early and what is late?
spontaneous termination of a pregnancy before 24 weeks
early = <12 weeks
late= 12-24 weeks
before what gestation can medical management of a miscarraige be used?
before 13 weeks
what defines recurrent miscarriages ?
3+ miscarriages
what are the main causes of recurrent miscarriage
anti-phospholipid syndrome
endocrine - poorly controlled diabetes
smoking
uterine abnormality
what may be given to those with recurrent miscarraiges ?
low molecular weight heparin and aspirin
what sign may be seen on transvaginal USS of ectopic
blob sign
