2. CASE 1.1
“My period is 2 weeks late and I am bleeding.”
A 23-year-old nulliparous woman has had 6 weeks of amenorrhoea.
She has not been using any contraception. She normally has a regular
menstrual cycle every 28 days. A pregnancy test is positive. She has
noticed slight vaginal spotting.
3. WHAT IS THE LIKELY DIFFERENTIAL DIAGNOSIS?
Miscarriage
Ectopic Pregnancy
Molar Pregnancy
4. Six weeks of amenorrhoea and a positive pregnancy
test,after regular menstrual cycles,indicate an early
pregnancy . These small amount of bleeding is a sign
that the patient is threatening to have a miscarriage.
11. CASE 1.1
“My period is 2 weeks late and I am bleeding.”
A 23-year-old nulliparous woman has had 6 weeks of amenorrhoea.
She has not been using any contraception. She normally has a regular
menstrual cycle every 28 days. A pregnancy test is positive. She has
noticed slight vaginal spotting.
12. What additional features in the history would
you seek to support a particular diagnosis?
How much blood?
How’s the pain?
Do you pass out anything?
13. What clinical examination would you perform
and why?
Haemodynamic status
General exam, vitals, conjunctival colour
Abdominal Exam
To assess uterine size, to exclude acute abdomen
Per Speculum
To see if os is open , any fetal tissues, cervix.
VE and bimanual exam
Assess os, Elicit cervical excitation and adnexal mass in
ectopic pregnancy
15. Inevitable Miscarriage
Pain : Considerable
Bleeding : Heavy
Os : Open
Ultrasound is important in determining the
:
absence or persistence of
conception products inside
uterine cavity
16. Complete Miscarriage
Pain : Slight
Bleeding : Slight-moderate
Os : Open, then close
afterwards
Ultrasound Empty uterus
:
17. Silent Miscarriage
Pain : Absent
Bleeding : Slight, chronic
Os : Close
Ultrasound failure to identify fetal heart beat
:
Gestational sac >20mm in diameter and
no embryonic/fetal part can be seen
6 mm embryo with no heart activity on
TVS
18. Molar Pregnancy
Pain : Slight/None
Bleeding : Slight-moderate
Os : Close
Ultrasound Classic “snow-storm”
:
appearance of vesicles
Honeycomb appearance
19. Ectopic Pregnancy

May see adnexal mass
21. CASE 1.1
“My period is 2 weeks late and I am bleeding.”
A 23-year-old nulliparous woman has had 6 weeks of amenorrhoea.
She has not been using any contraception. She normally has a regular
menstrual cycle every 28 days. A pregnancy test is positive. She has
noticed slight vaginal spotting.
22. What investigations would be most helpful and
why?
Urine pregnancy test
A quick test but may be unreliable
FBC
To assess Hb, TWC
Blood group and GSH
To check rhesus status, and to prepare for tranfusion
Ultrasound
To locate the fetus, to assess viability and to look for POC
Histology
Any tissues expelled should be investigated to exclude
molar or ectopic pregnancy
23. Ultrasound assessment
Look for pregnancy within the uterus
Presence of fetal heart
Should be present 6 weeks
If CRL< 6mm or MSD<20mm with no yolk
sac/fetus – rescan
Uncertain viability and unknown location
Presence of yolk sac
Adnexal masses
Free fluid/ endometrial thickness

35. Should all women with early pregnancy loss
receive anti-D immunoglobulin?
36. Non-sensitised rhesus (Rh) negative women
Anti-D
should receive anti-D immunoglobulin in the

46. What is the advantages of prostaglandin
administration prior to surgical abortion?
47. “ significant reductions in
dilatation force,
haemorrhage and
“
uterine/cervical trauma.
There is no randomised evidence to guide practice in cases of first-
trimester miscarriage,particularly in the presence of an intact sac
49. “ There is insufficient evidence to
recommend routine antibiotic
prophylaxis prior to surgical uterine “
evacuation.
Antibiotic prophylaxis should be given based on
individual clinical indications
A randomised trial of prophylactic doxycycline in curettage for incomplete
miscarriage did not demonstrate an obvious benefit
50. What are the alternatives to surgical uterine
evacuation for miscarriage?
51. Medical methods
are an effective alternative
in the management of
confirmed first-trimester
miscarriage.
53. Higher success rates were associated with
Incomplete miscarriage (70–96% success rate)
High-dose misoprostol (1200–1400 micrograms),
Prostaglandins administered vaginally
and clinical follow-up without routine ultrasound.

54. Misoprostol
prostaglandin analogue
cheap, highly effective
active orally and vaginally
No significant difference in successful outcome
May bleed up to 3 weeks
Used in combination with mifepristone
S/E: Diarhhoea, abd pain, nause, headache
55. Cervagem
Gameprost
Inserted into the vagina
S/E: vaginal bleeding or uterine pain
nausea, vomiting, lower abdominal pain, backache
headache, slight fever, flushing, chills
56. “Vaginal misoprostol for the termination of
second and third trimester of pregnancy “
appears as effective as cervagem, but
information about maternal safety is limited.
57. effective regimens for
missed miscarriages
•a higher dose of prostaglandin with longer duration of use
•or, alternatively, priming with antiprogesterone.
58. Incomplete miscarriage
Can be managed with prostaglandin alone
No statistical difference in efficacy between
surgical and medical evacuation for
incomplete miscarriage and for early fetal
demise at gestations less than 71 days or sac
diameter less than 24mm.
59. Threatened miscarriage
No specific management
Reassurance
Rest
Sedation
weekly ultrasound examination
61. Expectant management
Watch and wait
Serial scans and HCG
More successful in incomplete miscarriage
28% success if intact sac
94% if incomplete
May have prolonged bleeding
Can convert at anytime to medical/surgical
62. Concerns have been raised about the
infective risks of non-surgical management
But published data suggest a reduction in
clinical pelvic infection and no adverse
affects on future fertility.
66. Septic miscarriage
Genital swab
I/V broad spectrum antibiotics to cover g(+)ve, g(-)ve
and anaerobic organism
change antibiotics according to culture and sensitivity
result
Remove the septic focus
ERPOC
Laparotomy and drainage for pelvic abscess
TAH for septic uterus and uterine perforation
67. What are the advantages of arranging
histological examination of tissue passed
at the time of miscarriage?
68. Tissue obtained at the time of miscarriage
should be examined histologically to
confirm pregnancy and
to exclude ectopic pregnancy or
unsuspected gestational trophoblastic
disease.
69. CASE 1.2
A 32-year-old patient, Mrs. A, immigrated to the United
States several years ago. Following the birth of their first
daughter, Mrs. A has had three miscarriages between
eight and 12 weeks' gestation, the most recent one being
one month ago.
70. What are the recommended investigations of
couples with recurrent first-trimester
miscarriage and second-trimester miscarriage?
71. Investigations would include the following:
•chromosomal analysis of the products of conception;
•chromosomal analysis of both parents – a chromosomal
abnormality (e.g.balanced translocation) will be
diagnosed in one of the partners in 5–7per cent of cases
of recurrent abortion;
•maternal blood for anticardiolipin antibodies and lupus
anticoagulant
72. Should I be given some kinda drug to avoid
getting another miscarriage?
73. “Aspirin alone or in combination with heparin is
being prescribed for women with unexplained
Recurrent miscarriage,with the aim of improving
pregnancy outcome.”

74. Recent Data suggest that the use of empirical
treatment in women with unexplained
recurrent miscarriage is unnecessary and
should be resisted.

75. In the absence of any identifiable cause,what
are my chances of achieving an ongoing
pregnancy on the next occasion?
76. There is a 60–70% likelihood of
successful pregnancy if no cause is
found for recurrent miscarriage
77. Is there potential benefit from support
and follow-up after pregnancy loss?
78. “All professionals should be aware of the
psychological sequelae associated with
pregnancy loss and should provide support,
follow-up and access to formal counselling when
necessary. “
