25
Explain the 3 ways of managing a miscarriage at >6wks
- Expectant management - Medical management (misoprostol) - Surgical management
25
What USS findings suggest a non-viable pregnancy ?
- When the crown rump length is 7mm or more with no fetal HB
25
How is a miscarriage at <6 wks managed
- Expectantly (as long as there is no pain or other complications) - Repeat urine pregnancy at 7-10 days to confirm
26
What is involved in the medical management of a miscarriage
Misoprostol (vaginal suppository or orally)
27
How does misoprotol work
- Prostoglandin analogue - Leads to release of prostaglandins with soften cervix and stimulate uterine contractions
28
4 SE of misoprostol
Heavier bleeding Pain Vomiting Diarrhoea
29
what are the 2 surgical options for managing a miscarriage and what is given prior to them
- Manual vacuum aspiration (local) - Electrical vacuum aspiration (general) - Misoprostol is given prior - Anti-rhesus D prophylaxis
30
What is the criteria for manual vacuum aspiration of a miscarriage
-> <10 wks gestation
31
what are the 2 management options for RPOC ?
- Medical with misoprostol - Surgical with evacuation of RPOC - general anaesthetic
32
What is involved in evacuation of RPOC and a key complication
- Vacuum aspiration and curettage - Complication : endometritis (infection of endometrium).
33
what is considered as recurrent miscarriage and when are investigations initiated ?
-> 3 or more -> Three or more first-trimester miscarriages -> One or more second-trimester miscarriages
34
Give 7 causes of recurrent miscarriages
- Idiopathic - Antiphospholipid syndrome - Hereditary thrombophilias - Uterine abnormalities - Genetic factors - Chronic histiocytic intervillositis - Chronic diseases : DM, untreated thyroid, SLE
35
what is given to women with antiphospholipid syndrome to reduce risk of recurrent miscarriages
- Low dose aspirin - LMWH
36
Give 3 inherited thrombophilias that can cause recurrent miscarriages
- Factor V Leiden (most common) - Factor II (prothrombin) gene mutation - Protein S deficiency
37
what uterine abnormalities can cause recurrent miscarriages
- Uterine septum (a partition through the uterus) - Unicornuate uterus (single-horned uterus) - Bicornuate uterus (heart-shaped uterus) - Didelphic uterus (double uterus) - Cervical insufficiency - Fibroids
38
what is a rare cause of recurrent miscarriage, particularly in the 2nd trimester
Chronic Histiocytic Intervillositis
39
when can an abortion be carried out before 24 wks
- If continuing pregnanct involve sgreater risk to physical or mental health of : 1. The woman 2. Existing children of the family
40
When can an abortion be carried out at any time ?
- Continuing the pregnancy is likely to risk the life of the woman - Terminating the pregnancy will prevent “grave permanent injury” to the physical or mental health of the woman - There is “substantial risk” that the child would suffer physical or mental abnormalities making it seriously handicapped
41
what are the legal requirements for an abortion to be carried out ?
- 2 registered medical practitioners must sign to agree abortion is indicated - It must be carried out by a registered medical practitioner in an NHS hospital or approved premise
42
what is involved in a medical abortion ?
- Mifepristone (anti-progestogen) - Misoprostol (prostaglandin analogue) 1 – 2 day later -> from 10wks gestation, additional doses are given until expulsion
43
when would women having a medical aortion require anti-D prophylaxis
Rhesus negative women with gestational age of 10 wks or above
44
What are the two surgical options for abortion and what determines the choice ?
- Cervical dilation and suction (up to 14 wks) - Cervical dilation and evacuation with forceps (from 14-24 wks)
45
when is a urine pregnancy test done following an abortion ?
3 wks after
46
Give 5 complications of an abortion
- Bleeding -Pain -Infection - Failure of the abortion (pregnancy continues) - Damage to the cervix, uterus or other structures
47
when does N&V develop in pregnancy, when does it peak and when does it resolve
- Starts 4-7 wks - Peaks 10-12 wks - Resolve 16-20 wks (can persist)
48
how is hyperemesis gravidarum diagnosed ?
- "Protracted NVP" + ~ More than 5% weight loss compared to before pregnancy ~ Dehydration ~ Electrolyte imbalance
49
How is the severity of NVP assessed ?
-> Pregnancy-Unique Quantification of Emesis (PUQE) : - <7 : mild - 7-12 : moderate - >12 : severe
50
How can mild cases NVP be managed ?
- Oral antiemetics admission 1. Prochlorperazine (stemetil) 2. Cyclizine 3. Ondansetron 4. Metoclopramide
51
when would admission for NVP be considered ?
- Unable to tolerate oral antiemetics or keep down any fluids - More than 5 % weight loss compared with pre-pregnancy - Ketones are present in the urine on a urine dipstick (2 + ketones on the urine dipstick is significant) - Other medical conditions need treating that required admission
52
What might moderate-severe cases of NVP require ?
- IV or IM antiemetics - IV fluids (normal saline with added potassium chloride) - Daily monitoring of U&Es while having IV therapy - Thiamine supplementation to prevent deficiency (prevents Wernicke-Korsakoff syndrome) - Thromboprophylaxis (TED stocking and low molecular weight heparin) during admission
53
what is a complete hydatidiform molar pregnancy
- Two sperm cells fertilise an ovum containing no genetic material - No fetal material forms
54
what is a partial hydatidiform molar pregnancy ?
- Two sperm fertilise a nomral ovum - 3 sets chromosomes (Haploid cell) - Some fetal material forms
55
what features suggest a molar pregnancy over a normal pregnancy
- More severe morning sickness - Vaginal bleeding - Increased enlargement of the uterus - Abnormally high hCG - Thyrotoxicosis (hCG can mimic TSH and stimulate the thyroid to produce excess T3 and T4)
56
what is seen on USS in a molar pregnancy
"Snowstorm appearance" of the pregnancy
57
How is a molar pregnancy managed
- Evacuation of the uterus - Products of conception are sent for histological examination - hCG levels monitored until they return to normal - Occasionally metastasise requiring systemic chemo
58
Typical presentation of ovarian hyperstimulation syndrome
- Ascites - Vomiting - Diarrhoea - High haematocrit
59
Possible cause of ovarian hyperstimulation syndrome
Ovulation induction (Gonadotropin therapy)
60
risk of ondansetron in pregnancy
associated with a small increased risk of cleft lip / palate if used in first trimester
61
Management of thrush in pregnancy
Clotrimazole pessary (oral fluconazole is CI)
62
Most likely location of ectopic pregnancy
Ampulla of fallopian tube
63
with surrogacy, at birth who is the child's legal mother
Whomever gives birth to the child
64
What is required following a medical termination of pregnancy ?
'Multi-level pregnancy test' two weeks later
65
When should a woman take aspirin to reduced the risk of hypertensive disorders in pregnancy
women with the following should take aspirin 75-150mg daily from 12 weeks gestation until the birth ≥ 1 high risk factors ≥ 2 moderate factors
66
High risk factors for HTN in pregnancy
- Hypertensive disease in a previous pregnancy - Chronic kidney disease - Autoimmune disease, such as systemic lupus erythematosus or antiphospholipid syndrome - Type 1 or type 2 diabetes - Chronic hypertension
67
Moderate risk factors for HTN in pregnancy
- First pregnancy - Age 40 years or older - Pregnancy interval of more than 10 years - Body mass index (BMI) of 35 kg/m² or more at first visit - Family history of pre-eclampsia - M ultiple pregnancy
