Q

management for pre eclampsia

A
usually conservative
delivery of placenta is the only 'cure'
labetalol if 150/100 +
magnesium sulphate for seizure risk if severe
fluid restrictions

17
Q

management of eclampsia

A
resus
magnesium sulfate
intubation if required

(caesarean likely)
18

what are the criteria for screening for gestational diabetes

A
BMI>30
prev macrosomic baby
prev GDM
1st relative diabetic
family origin with increased risk associated
22
Q

risks of Gestational diabetes to foetus

23
Q

causes of antepartum haemorrhage

A

*placenta previa
*placental abruption
local trauma, domestic violence, vasa previa, uterine rupture

24
Q

presentation of antepartum haemorrhage

A

bleed +/- pain

contractions, foetal distress, malpresentation, hypovolaemic shock

25
Q

management of antepartum haemorrhage

A
estimate blood loss
bloods- FBC, group and save, crossmatch, clotting studies, U&Es, LFTs
foetal monitoring and ultrasound scan
antiD for resus negative
corticosteroids if preterm risk
avoid vaginal exam
26
Q

why should a vaginal examination be avoided in antepartum haemorrhage?

A

if previa then risk of torrential bleed

27
Q

what is placenta previa?

A

partial or full covering of the cervical os by the placenta

28
Q

risk factors for placenta previa

A
previous placenta previa
previous caesarean
older maternal age
increased parity
smoking
cocaine use in pregnancy
previous spontaneous or induced abortion
endometritis
assisted conception
29
Q

presentation of placenta previa

A
routine scan
painless bleed 28w+
post coital bleed
spontaneous preterm
abnormal lie- transverse/oblique
30
Q

diagnosis for placenta previa

A

ultrasound for leading edge of placenta

31
Q

management of minor placenta previa

A

vaginal delivery possible

if <2cm from os then caesarean

32
Q

management of major placenta previa

A

caesarean
no penetrative intercourse
hospitalisation from 34 weeks if bleed

33
Q

what are the risks of a placenta previa?

A

major haemorrhage- hypovolaemic shock
VTE- associated with hospitalisation
Foetal prematurity

36
Q

what are the different types of breech presentation?
