Q

19
Q

What is important before in conception in pre-existing diabetes?

A

Counselling to inform women of the implications on pregnancy

20
Q

What should be aimed for before conception in pre-existing diabetes?

A

HbA1c <6.1%

21
Q

Why is a low HbA1c desirable before conception in pre-existing diabetes?

Is metformin usually continued in pregnancy?

A

Yes

24
Q

Are other oral hypoglycaemics usually continued in pregnancy?

What medication that may treat complications of diabetes may not be safe in pregnancy?

A

ACE inhibitors

26
Q

What supplement should women with pre-existing diabetes take increased doses of pre-conception?

A

Folic acid

27

Who may be involved in an obstetric diabetes clinic?

A
  • Obstetrician
  • Endocrinologist
  • Diabetes specialist nurse
  • Dietician
  • Specialist midwife
28
Q

What is the goal of treating pre-existing diabetes in pregnancy?

A

Keep blood glucose as close to normal as possible whilst avoiding hypoglycaemia

29
Q

What is often required in order to achieve the aims of controlling pre-existing diabetes in pregnancy?

A
  • More frequent capillary blood glucose monitoring

- Tighter control

30
Q

How is fetal well-being measured in pre-existing diabetes in pregnancy?

A

Fetal assessment for abnormalities

31
Q

What abnormality assessments may be given to a fetus of a pregnant woman with pre-existing diabetes?

  • Routine anomaly scan at 20 weeks
  • Additional scanning for cardiac abnormality
  • Regular serial growth scans
32
Q

Why are regular serial growth scans useful in fetus of a pregnant woman with pre-existing diabetes?

A

To detect macrosomia and fetal growth restriction

33
Q

How can maternal wellbeing be increased in women with pre-existing diabetes in pregnancy?

A
  • Low-dose aspirin from second trimester
  • Keep BP low in women with vascular disease
  • Ophthalmic assessment each trimester
34
Q

What can low dose aspirin from the second trimester do for women with pre-existing diabetes in pregnancy?

A

Reduce the risk of pre-eclampsia

35
Q

Where should women with pre-existing diabetes give birth?

A

Hospital with neonatal facilities

36
