Q

What is the treatment for VTE in obstetrics?

A

LMWH
As it doesn’t cross the placenta and reduces risk of bleeding

Death

18
Q

What are the treatment options for VZV during pregnancy?

A
  • Symptomatic treatment and hygiene
  • Oral Aciclovir should be prescribed if they present within 24 hours of onset of rash
19
Q

What are the risks of VZV infection during pregnancy?

A
  • If infection occurs in last 2 weeks of pregnancy, there is significant varicella infection in new born
  • Avoid delivery until at least 7 days since appearance of rash if possible
  • Inform neonatologist
20
Q

What is preterm labour?

A

Labour before 37 weeks gestation
- 8-10% of all deliveries -

21
Q

What is the survival rate at 23 weeks gestation?

A

8%

22
Q

What is the survival rate at 28 weeks gestation?

A

74%
an increase of 3% each day after that

23
Q

What are the fetal issues of prematurity?

A
  • Respiratory distress syndrome
  • Necrotising enterocolitis
  • Retinopathy of prematurity
  • Sepsis
  • Intraventricular haemorrhage
  • Periventricular leucomalacia
  • long-term cognitive and sensory impairment
24
Q

What is Periventricular leucomalacia?

A

A type of brain injury most common in premature babies

The white matter (leuko) surrounding the ventricles of the brain (periventricular) is deprived of blood and oxygen leading to softening (malacia)

25
Q

What are the risk factors for premature birth?

A
  • Previous preterm delivery
  • Previous preterm prelabour rupture of membranes (PPROM)
  • Mid-trimester pregnancy loss
  • Congenital uterine anomalies
  • Multiple pregnancy
  • Vaginal bleeding
  • Short cervix
  • Previous multiple LLETZ of the cervix or cone biopsy
26
Q

What is meant by a short cervix?

A

One that is less than 25mm (2.5cm) long at around 20 weeks of pregnancy

27
Q

What is LLETZ?

A

AKA large loop excision of the transformation zone

Treatment to remove cell changes (abnormal cells) in the cervix

28
Q

What are some methods of preventing pre-term labour?

A

1.Treatment of infection
2. cervical cerclage (sewing cervix shut with stitches)
3.Tocolysis (medical treatment to stop preterm contractions)

29
Q

Which medications are used in tocolysis?

A
  • Betamimetics (such as terbutaline)
  • Magnesium sulphate
  • Prostaglandin inhibitors (like indomethacin, ketorolac)
  • Calcium channel blockers (nifedipine)
  • Nitrates (like nitroglycerine)
  • Oxytocin receptor blockers (like atosiban)
30
Q

How is preterm labour diagnosed?

A

Abdominal and pelvic examination of the woman and assessment of uterine activity

31
Q

What % of women will go into labour 24hours after PROM?

A

60%

32
Q

What is PROM?

A

Premature rupture of membranes

33
Q

What are the risk factors for PROM?

A
  • Infections
  • Smoking
  • Previous pre-term delivery
  • Vaginal bleeding
  • Polyhydramnios
  • Multiple gestation
  • Cervical insufficiency
  • Chorioamnionitis
34
Q

What is Chorioamnionitis?

A

Infection of placenta and amniotic fluid
- Often happens when the amniotic sac is broken for a long time

35
Q

What is the amnisure test?

A

Test strip test for the detection of the placental alpha microglobulin-1 protein (PAMG-1)
Used to help diagnose ruptured membranes in patients presenting with signs and symptoms of PROM

  • False positive if done after vaginal examination or if there is significant vaginal bleeding
36
Q

What is P-PROM?

A

Preterm premature rupture of the membranes

37
Q

What are the degrees of post-partum haemorrhage?

A

Minor PPH: 500-1000ml blood loss without clinical signs of shock

Major PPH: >1000ml blood loss, or <1000ml visible blood loss with clinical signs of shock

Massive Obstetric Haemorrhage: >2500mls or requiring 5units of blood transfusion

38
Q

What is the difference between primary and secondary post-partum haemorrhage?

A

Primary: within 24hours of delivery

Secondary: 24hours to 12 weeks post-delivery

39
Q

What are the risk factors for post-partum haemorrhage?

A
  • Previous PPH
  • Multiparity
  • Overdistension of the uterus (polyhydramnios/macrosomia/multiple pregnancy)
  • Clotting disorders
  • Antepartum haemorrhage
  • Placenta praevia
  • Prolonged labour
  • Operative birth or caesarean section, episiotomy
  • Induction of labour
  • General anaesthesia, magnesium sulphate, or nifedipine
40
Q

What are the causes of post-partum haemorrhage?

A
  • Tone (most common)
  • Trauma to uterus
  • Thrombin (coagulation disorder)
  • Tissue preventing contraction
41
Q

Which medications are given to help the uterus to contract?

A

Oxytocin, Ergometrine, Carboprost, or Misoprostol
