Menorrhagia, anaemia, bulk-related symptoms e.g. bloating/urinary frequency →? uterine fibroids how to manage
COCP
is Undiagnosed vaginal bleeding is a contraindication for hrt
yes
A 49-year-old patient presents with hot flushes and mood swings. She has no previous medical history or family history. She has been amenorrheic since her Mirena (levonorgestrel) coil was placed 2 years ago. She would like to consider HRT with the least side effects
oestrogen patch
The patient requires combined HRT as she has a uterus, so requires progesterone for protection of the endometrial lining against estrogen. However, the patient has a Mirena coil in situ, which is the only form of contraception licensed to be used as the progesterone component in HRT. It is licensed for 4 years if used as HRT.
Therefore the patient only requires oestrogen preparation only.
Transdermal oestrogen such as patches and gels do not have an increased risk of deep vein thrombosis, compared to oral oestrogen preparations

risk factor for placental abruption
ABRUPTION:
A for Abruption previously;
B for Blood pressure (i.e. hypertension or pre-eclampsia);
R for Ruptured membranes, either premature or prolonged;
U for Uterine injury (i.e. trauma to the abdomen);
P for Polyhydramnios;
T for Twins or multiple gestation;
I for Infection in the uterus, especially chorioamnionitis;
O for Older age (i.e. aged over 35 years old);
N for Narcotic use (i.e. cocaine and amphetamines, as well as smoking)
A woman at moderate or high risk of pre-eclampsia should take
aspirin 75-150mg daily from 12 weeks gestation until the birth

Pregnant women ≥ 20 weeks who develop chickenpox are generally treated with
oral aciclovir if they present within 24 hours of the rash
The requirements for instrumental delivery can be easily remembered by the mnemonic FORCEPS:
Fully dilated cervix generally the second stage of labour must have been reached
OA position preferably OP delivery is possible with Keillands forceps and ventouse. The position of the head must be known as incorrect placement of forceps or ventouse could lead to maternal or fetal trauma and failure
Ruptured Membranes
Cephalic presentation
Engaged presenting part i.e. head at or below ischial spines the head must not be palpable abdominally
Pain relief
Sphincter (bladder) empty this will usually require catheterization
what is bishops score
Evaluating cervical readiness for labour
What normally happens to blood pressure during pregnancy?
Falls in first half of pregnancy before rising to pre-pregnancy levels before term
