- Pre-eclampsia
- Cerebral venous thrombosis
- Intracranial mass
- Stroke
- Hypoglycaemia
- Migraine
- Hyponatraemia
- Drugs/Withdrawal

What epileptic medication has highest risk of foetal abnormality associated with it?
Sodium valproate
When should a pregnant woman with epilepsy be started on Vit K in the last 4 weeks of pregnancy, and why?
If on following antiepileptic drugs - All enzyme inducers - clotting factors may be reduced in the newborn
- Carbemazepine
- Phenytoin
- Primidone
- Phenobarbitol
- Ethosuximide
When is fitting in labour indicative for a C-section?
Only if in status epilepticus - otherwise
Should you continue anti-epileptic drugs during labour?
Yes
Are epidurals safe in epileptic women going through labour?
Yes
How would you manage seizures during labour that were not self-limiting?
Benzodiazepines - lorazepam, diazepam
Why are seizures in epilptic pregnant women common intrapartum and postpartum?
- Sleep deprivation
- Reduced drug efficacy - increased volume of distribution, increased serum binding
- Hyperventilation
- Hormonal changes
- Nausea and vomiting
Why would you give vitamin K to a child post birth?
To reduce risk of haemorrhagic disease of the newborn
What might you have to do with the dose of oral contraception in post natal epileptic women if they are on enzyme inducing drugs?
Increase dose of oral contraceptive
What cardiopulmonary disease carries a high risk of mortality in pregnant women?

What is gestational diabetes?
Diabetes which develops during pregnancy which reverts to normal after pregnancy
What are risk factors for gestational diabetes?
- BMI > 30
- Previous macrosomic baby
- Previous GDM
- FH of diabetes
- High risk groups - asian origin
- Previous polyhydramnios
Why can insulin requirements of pregnant type I/type II diabetics increase?
Increase in:
- Human plcaental lactogen
- Progesterone
- B-HCG
- Cortisol
Why can foetal hyperinsulinaemia occur in pregnancy of diabetic women?
Maternal glucose crosses the placenta and induces increased insulin production in the foetus -> Causes macrosomia
What complications are those who have type I/II diabetes at risk of during pregnancy?
- Foetal congenital abnormalities - especially if blood sugars high peri-conception
- Miscarriage
- Pre-eclampsia
- Macrosomia
- Polyhydramios
- Operative delivery
- Shoulder dystocia
- Worsening maternal nephropathy, retinopathy, hypoglycaemia, reduced awareness of hypoglycaemia
- Infections
- Stillbirth
- Neonatal - impaired maturity, neonatal hypoglycaemia, jaundice
Complications of diabetes in pregnancy
- Shoulder dystocia
- Macrosoma
- Amniotic fluid excess
- Stillbirth
- Hypertension and neonatal hypoglycaemia
What measures would you take preconception when managing someone who wants to get pregnant and has diabetes?
Better glycaemic control
- 4-7mmol/l pre-conception
- HbA1c <6.1% (<43 mmol/mol)
- Folic acid 5mg
- Dietary advice/Weight reduction
- Retinal assessment
- Renal assessment
What antenatal measures would you want to take during pregnancy when managing a diabetic woman?
- Aim to stay normoglycaemic
- Increase BM monitoring - Provide kits for hypo’s
- Detailed scan at 18-20 weeks - look for foetal abnormality
- Insulin increase - can be 50-100%, but may need to decrease towards end
- Monitor foetal growth
- Regular U+E’s, MSSU, HbA1c, Eye exam
- Aim for tight control
