REPRO 6 Flashcards
(47 cards)
when does blood pressure normally fall in pregnancy
second trimester
when is htn in pregnancy diagnosed (3)
> = 140/90 on two occasions
DBP >110 or SBP >160
rise of SBP by 30 or DBP by 15 or more from booking
complications of hypertension during pregnancy
PET, IUGR, abruption
when is pregnancy induced hypertension diagnosed and when does it resolve
second half of pregnancy and resolves 6 weeks PN
what percentage of patients with hypertension go on to develop PET and what is the recurrence rate
15%
high
treatment - in order of hypertension - and CI/SE
Labetalol PO/IV asthma, IUGR
Nifedipine PO
IV hydralazine
Methyldopa - can cause rebound hypertension
what is the triad of PET
oedema
hypertension
proteinuria >=3g/24h
when is maternal artery doppler done
what is it checking for
20-24weeks
placentation
what is abnormal placentation
failure of trophoblasts and placentation leading to low flow and high pressure
what is HELLP syndrome
haemolysis, elevated liver enzymes and low platelets
what is the normal amniotic fluid index and what is it in PET
6-22
<6
complication involving mean arterial pressure
MAP >=150 -> cerebral haemorrhage
what should the blood pressure aim be
140-150/90-100
what is eclampsia
PET and tonic clonic gen seizures
how many patients have seizures before the onset of hypertension/proteinuria
1/3
when do most patients have seizures
in labour or after
what is eclampsia associated with
ischaemia/cereberal vasospasm
treatment of eclampsia - htn
Labetalol, nifedipine, hydralazine
treatment for eclampsia - seizures
if further seizure
if even further seizure
4g IV magnesium sulphate loading dose over 5-10mins
then 1g/hour infusion for 24 hours
2g magnesium sulphate
Diazepam 10mg IV
eclampsia fluid balance and why is this important
run patient dry at 80mls/hour
giving fluids can lead to pulmonary oedema
what is given to induce labour in eclampsia and what should be avoided
syntocin
ergometrine - causes hypertension
steroids in pregnancy - what and till when
12mg beclamethasone IM 2 doses 24h apart
up to 36 weeks
mod risk factors of PET
first pregnancy >=40 pregnancy interval >10y FH multuple preg BMI >35
high risk factors for PET
prev PET/htn CKD AI disease like SLE antiphos DM type 1 or 2 chronic hypertension
