Q

What is a septic miscarriage and what are the signs and symptoms?

A

Any of the above with clinical infection of the uterus and its contents

Signs and symptoms
Temp ≥38°C
Maternal PR>100bpm
Purulent vaginal discharge
Pelvic pain/tenderness

16
Q

How is a septic miscarriage managed?

A
  • Resuscitation: IV fluids +/- blood transfusion
  • Monitor Vital Signs and urine output
  • Benzyl Penicillin 2 MU IV Q6H, Gentamycin 320mg IV OD, Metronidazole 500mg IV Q8H
  • Switch to DCN 100mg BD plus Metronidazole 400mg TDS X 7 days when able to take oral drugs
  • Evacuation by experienced doctor to avoid perforation
17
Q

Define ectopic pregnancy.

A

Ectopic pregnancy is a pregnancy that occurs outside of the uterus.

18
Q

Where do most ectopic pregnancies implant?

A

Ampulla of the fallopian tube

19
Q

Give 6 risk factors for ectopic pregnancy.

A
  • History of prior ectopic pregnancy
  • History of tubal surgeries
  • History of pelvic inflammatory disease
  • Smoking
  • Infertility
  • Prior abdominal surgeries
  • Failure of contraceptive method
  • Fundal fibroid
  • Age 35-45 years
20
Q

What is the classic triad for ectopic pregnancy?

A

Abdominal pain, amenorrhea and vaginal bleeding

21
Q

List 4 investigations that would be important in an ectopic pregnancy.

A

Urine pregnancy test, transvaginal ultrasound, blood samples for X-match

22
Q

How do you manage an ectopic pregnancy if unstable?

A

2 large-bore IV lines, take FBC, group & crossmatch

If in shock: Resuscitate with IV fluids (RL/NS), transfuse blood

If ruptured: Emergency laparotomy ± transfusion

If unruptured: Urgent laparoscopy/laparotomy

Send tissue for histology ± D&C if indicated

23
Q

How do you manage an ectopic pregnancy if stable?

A

Indications: Stable, no rupture/bleeding, normal FBC

Drug: Methotrexate (1st choice)

Follow-up: FP counseling, warn of future ectopic risk

24
Give 4 prerequisites for medical management of an unruptured ectopic pregnancy.
- Failed medical management - Any contraindication to use of methotrexate - Completed family - Surgery can be performed in form of salpingectomy or salpingostomy
25
Give 3 prerequisites for medical management of an unruptured ectopic pregnancy.
The woman should be stable, motivated and compliant to follow ups Beta- hCG < 3000 IU/L Absent cardiac activity Size of gestational sac < 4cm
26
What is a molar pregnancy?
A molar pregnancy (hydatidiform mole) is the result of a genetic error during the fertilization process that leads to the growth of abnormal tissue within the uterus.
27
What is a complete molar pregnancy?
A complete mole is caused by a single sperm combining with an egg which has lost its DNA
27
What will be the genotypes of complete molar pregnancies?
46XX or 46XY
27
Give 3 risk factors for ectopic pregnancy.
1. Previous history of molar pregnancy 2. Extreme age: Elderly patients with high parity Teenagers 3. Ethnicity: Asians, Hispanics, American Indians
27
What are the clinical features of a complete molar pregnancy?
- PV bleeding - Uterus larger than dates - Hyperemesis gravidarum - bHCG >100,000 - No foetal heart beat - Pre-eclampsia
28
When does a partial molar pregnancy occur?
Partial mole occurs when an egg is fertilized by 2 sperms or, by sperm which replicates itself yielding the genotype of 69 XXY or 92 XXXY
29
Name 5 investigations that you would do for a molar pregnancy.
- Urine pregnancy test - bHCG - FBC - U&Es + creatinine - LFTs - TFTs - CXR, Histology - USS pelvis and abdomen
30
What would be the USS findings for a complete molar pregnancy?
"snowstorm" or "bunch of grapes" pattern, with numerous fluid-filled cysts within the uterus and no visible fetal tissue
31
What would be the USS findings for a partial molar pregnancy?
Fetal tissue, which can be small or underdeveloped, along with cystic changes in the placenta
32
How do you manage a molar pregnancy?
- Ultrasound guided dilatation, suction and curettage - Consider anti-D for Rhesus negative mums Chemotherapy for neoplasia - bHCG 2 weekly until normal, then monthly for a year - Contraception for at least 6 months post normalization of bHCG (do not offer IUCD) - Counsel patient on importance of early antenatal care and order ultrasound to look for any recurrent mole.
33
What is Gestational Trophoblastic Disease (GTD)?
Diseases that arise from abnormal proliferation of placental trophoblastic cell
34
Which conditions does GTD include?
GTD includes hydatidiform mole (complete or partial) and Gestational Trophoblastic Neoplasia (GTN), choriocarcinoma, and placental site trophoblastic tumor
