Q

Ectopic pregancy - Surgical management criteria

A
  1. HCG >5000
  2. Size >35cm
  3. May be ruptured + Pain + Visible heart beat

Mx :
⦁ Saplingectomy - surgical removal of fallopian tube if no other issues with infertility
⦁ Saplingotomy - Contents are removed via an opening in the fallopian tube
- Indic if ; other risk factors for infertility, helps to preserve both fallopian tubes

Q

Misacarriage : Missed/Delayed miscarriage

A

Definition : Dead foetus within gestational sac before < 20 weeks without symptoms of expulsion

  1. Painless vaginal bleeding
  2. Pregnancy symptoms have resolved
  3. Cervical os : closed
  4. US : Gestational sac > 25 mm and no fetal parts can be seen/ empty sac
  • Missed miscarriage - empty gestation sac without foetal pole seen on Ultrasound
  • Complete miscarriage - all products of consumptions including gestational sac would be passed - nothing in the uterus

Q

Misacarriage : Inevitable miscarriage

A
  1. Pain and heavy bleeding with clots
  2. Cervical os : open
    If not all products of conception have been expelled this is - ‘Incomplete Miscarriage’

Q

Miscarriage : Investigations

A
  • TV US < 9 weeks
  • Transabdominal US > 9 weeks gestation
17
Q

Misacarriage : First line management

A
  1. 7-14 days of monitoring without intervention for spontaenous miscarriage and ejection of foetal contents
  2. If unsucessful - consider medical /surgical management
18
Q

Misacarriage : Indication for medical/surgical management

A
  1. Increased risk of haemorrhage
    ⦁ Late in first trimester
    ⦁ Coagulopathies
  2. Evidence of infection
19
Q

Misacarriage : Medical management

A
  1. Vaginal Misoprostol
    Prostaglandin analogue, binds to myometrial cells to cause strong myometrial contractions leading to the expulsion of tissue
20
Q

Misacarriage : Surgical management

A
  1. Vacum aspiration : under local anaesthetic in OP
  2. Surgical curettage : in theatre
21
Q

Mifepristone : MOA

A

Blocks the effects of progesterone - making both cervix and uterine vessels dilate, causing uterine contraction

22
Q

Termination of pregnancy : Upper limit

A

24 weeks of gestation

23
Q

Termination of pregnancy : Medical management

A

Indication : 0 - 10 weeks of pregnancy
1. Mifepristone : block the effects of progesterone
48 hours later
2. Misoprostol : cause uterine contraction and ejection of fetal contents
3. HCG pregnancy test in 2 weeks time

24
Q

Termination of pregnancy : Surgical management

A

Done under local anaesthesia
1. Vaccum aspiration
2. Dilatation and Evacuation

25
Q

Termination of pregnancy : Time line

A

Medical abortion
< 9 weeks
Late medical abortion 9-20 weeks
Vacuum aspiration : 7-15 weeks
Dilation and evacuation > 15 weeks
