Clinical triad of pre-eclampsia?
BP elevated, usually above 140/90
Proteinuria on dipstick or 0.3g or more over 24hrs collection
Oedema of the face/hands/legs/feet
Symptoms of pre-eclampsia
5
Headache Visual disturbance Vomiting Flash oedema Subcostal pain
Antihypertensives safe in pregnancy
3
- LABETALOL
- Methyldopa
- Nifedipine
Prenatal care in pre-eclampsia
incl. foetal monitoring x4
ONCE-ONLY proteinura assessment with dipsticks, if more than 1+, do P:CR or 24 collection
Control BP - almost always labetalol, usually only treat @ 150/100 or more
Measure BP several times per day
Bloods:
Regular U&Es, FBC, bilirubin
Foetal monitoring:
CTG @ diagnosis and weekly
USS foetal growth @ diagnosis
Amniotic fluid volume assessment @ diagnosis
Umbilical artery doppler velocimetry @ diagnosis
Regular assessment of syx
Timing of birth:
Manage conservatively (i.e. not immediate delivery) until 34 weeks unless severe where birth may be offered before
If moderate/mild, offer birth in 24-48hrs where HTN persists to 37+0
REMEMBER STEROIDS IF PRE 36 WEEKS
Intrapartum/postpartum antihypertensive use in pre-eclampsia
Intra: Monitor BP hourly in mild/mod Monitor BP continuously in severe Continue antihypertensive through labour Recommend operative birth in 2nd stage in severe cases not responding to treatment
Post:
Continue treatment postnatally and consider reducing if achieve below 140/90
Maternal complications of eclampsia
8
Placental abruption Neurological defecits Aspiration pneumonia HELLP Pulmonary oedema Cardiovascular problems - IHD, stroke, chronic HTN etc. Acute renal failure Death - via DIC, sepsis, stroke etc
Risk factors for pre-eclampsia
9
Primigravida Extremes of age HTN DM Previous pre-eclampsia Family hx Renal disease Obesity SLE, APLS
Clinical signs of pre-eclampsia
5
HTN Papilloedema Brisk reflexes Clonus Visual defect HELLP syndrome (Seizure - eclampsia)
Foetal complications of eclampsia
3
Prematurity - STEROIDS
IUGR
Bronchopulmonary disease
What is HELLP syndrome? When may it occur?
Haemolysis, elevated liver enzymes, low platelets
As a severe form of pre-eclampsia, patients are at high risk of DIC, abruption, renal failure and pulm oedema
Risks associated with pre-existing maternal DM?
6
Congen abnormalities Misacarriage Macrosomia as a result of foetal hyperinsulinaemia, predisposed to IUD Polyhydramnios Infection Stillbirth
Produce testosterone
Leydig cells
Form the blood-testis barrier
Sertoli cells
Days of the menstrual cycle when menses occur
1 to 7
Causes ovulation
Luteal surge, massive rise of LH @ day 14
Proliferating stage of menstrual cycle
days 7 to 14
Follice becomes this after ovulation
Corpus luteum
Causes proliferation of the endometrium
Progesterone
Produced by the corps luteum when it forms
Progesterone
Progesterone stimulates these to be formed in the endometrium
Spiral arteries
Increases uterine secretions to nourish embryo
Progesterone
Produced by a blastocyst upon implantation
hCG
Happens to the corpus luteum if no implantation, and why
atrophies and dies, as LH no longer being produced, then means no progesterone and next follicular phase can begin
Happens to corpus luteum if implantation occurs
hCG resembles LH, so CL can survive and continue to produce
