ECG
If you have 1 seizure, how long can you not drive for? (car and HGV)
Car - 6 months
HDV - 5 years
If you have epilepsy how long are you not allowed to drive for?
Car = 1 year (or 3 years during sleep) HGV = 10 years
1st line for generalised tonic-clonic seizures?
Sodium valproate (2nd line = lamotrigine, carbamazepine)
Treatment for absence seizures?
Sodium valproate or ethosuximide
sodium valproate particularly effective if co-existent tonic-clonic seizures in primary generalised epilepsy
1st line for myoclonic seizures?
Sodium valproate
2nd line = clonazepam, lamotrigine
1st line for partial seizures?
Carbamazepine
Lamotrigine, sodium valproate
Which drug may exacerbate absence seizures?
Carbamazepine
Medications safe for N&V in pregnancy?
Cyclizine Metoclopramide Prochlorperazine Promethazine Chlorpromazine Domperidone Ondansetron
Antibiotics for UTI in pregnancy?
Nitrofurantoin generally first line (but avoid at term) Then trimethoprim (but avoid in first semester)
Cholestasis
Bile cannot flow from the liver to the duodenum
What does the bishops score predict?
Whether induction of labour will be required or not
A score of 5 or less suggests that labour is unlikely to start without induction
What happens if you have a bishops score of less than 5?
Will require vaginal PGE2 for cervical ripening and induction of labour
(bishops score of less than 5 = labour unlikely to start without induction)
(a score of 8 or more indicates a ‘favourable’ cervix. Spontaneous labour is more likely with a score of greater than 8)
If someone has headache on the OCP what should you switch them to?
Should switch immediately - POP
the oestrogen in the OCP is what increases risk of ischaemic stroke = POP only one that doesn’t contain oestrogen
