29
Q

  • Pain
  • Vaginal bleeding (may be minimal bleeding)
  • Increased uterine activity
33
Q

Management of placental abruption

A

Management will vary from expectant treatment to attempting a vaginal delivery to immediate caesarean section

34
Q

Complications of placental abruption

A
  • Maternal shock, collapse (may be disproportionate to the amount of bleeding seen)
  • Foetal death
  • Maternal DIC, renal failure
  • Postpartum haemorrhage ‘couvelaire uterus’
35
Q

Preterm Labour

A
  • Onset of labour before 37 completed weeks gestation (259 days)
  • 32-36 wks mildly preterm
  • 28-32 wks very preterm
  • 24-28 wks extremely preterm
36
Q

Incidence of preterm labour

A
  • Around 5- 7% in singletons
  • 30 - 40% multiple pregnancy
37
Q

Predisposing factors for preterm labour

A
  • Muliple pregnancy
  • Polyhydramnios
  • APH
  • Pre-eclampsia
  • Infection eg UTI
  • Prelabour premature rupture of membranes
  • Majority idiopathic
38
Q

Diagnosis of preterm delivery

A

Contractions with evidence of cervical change on VE

39
Q

Management of preterm delivery

A
  • Consider tocolysis to allow steroids/ transfer
  • Steroids unless contraindicated
  • Transfer to unit with NICU facilities
  • Aim for vaginal delivery
40
Q

Neonatal Morbidity resulting from Prematurity

A
  • respiratory distress syndrome
  • intraventricular haemorrhage
  • cerebral palsy
  • temperature control
  • jaundice
  • infections
  • visual impairment
  • hearing loss
41
Q

Primary post partum haemorrhage

A

Primary post-partum haemorrhage is the loss of >500 ml of blood per-vagina within 24 hours of delivery.

It can be classified into two main types:

  • Minor PPH – 500-1000ml of blood loss
  • Major PPH – >1000ml of blood loss
42
Q

Causes of primary post partum haemorhage

A
  • Tone
    • ‘Tone’ refers to uterine atony, which is the most common cause of primary post-partum haemorrhage. This is where the uterus fails to contract adequately following delivery, due to a lack of tone in the uterine muscle.
    • The risk factors for uterine atony include:
      • Maternal profile: Age >40, BMI > 35, Asian ethnicity.
      • Uterine over-distension – multiple pregnancy, polyhydramnios, fetal macrosomia.
      • Labour – induction, prolonged (>12 hours).
      • Placental problems – placenta praevia, placental abruption, previous PPH.
  • Tissue
    • ‘Tissue’ refers to retention of placental tissue – which prevents the uterus from contracting. It is the second most common cause of 1° PPH
  • Trauma
    • This refers to damage sustained to the reproductive tract during delivery (e.g. vaginal tears, cervical tears). Risk factors include:
      • Instrumental vaginal deliveries (forceps or ventouse)
      • Episiotomy
      • C-section
  • Thrombin
    • ‘Thrombin’ refers to coagulopathies and vascular abnormalities which increase the risk of primary post-partum haemorrhage:
      • Vascular – Placental abruption, hypertension, pre-eclampsia.
      • Coagulopathies – von Willebrand’s disease, haemophilia A/B, ITP or acquired coagulopathy i.e. DIC, HELLP.
43
Q

Managment of uterine atony

A
  • Bimanual compression to stimulate uterine contraction – insert a gloved hand into the vagina, then form a fist insider the anterior fornix to compress the anterior uterine wall and the other hand applies pressure on the abdomen at the posterior aspect of the uterus (ensure the bladder is emptied by catheterisation).
  • Pharmacological measures – act to increase uterine myometrial contraction.
  • Surgical measures
    • intrauterine balloon tamponade,
    • B-lynch suture
    • bilateral uterine or internal iliac artery ligation
    • hysterectomy (as a last resort)
44
Q

Pharmacological managment of primary post partum haemorrhage

A
  • Syntocinon (synthetic oxytocin)
  • Ergometrine
  • Carboprost (prostaglandin analogue)
  • Misoprolol (prostaglandin analogue)
45
Q

Preventative measures to reduce risk and consequence of post partum haemorrhage

A
  • Treating anaemia during the antenatal period
  • Giving birth with an empty bladder (a full bladder reduces uterine contraction)
  • Active management of the third stage (with intramuscular oxytocin in the third stage)
  • Intravenous tranexamic acid can be used during caesarean section (in the third stage) in higher-risk patients
46
Q

Secondary post partum haemorrhage

A

Secondary postpartum haemorrhage is where bleeding occurs from 24 hours to 12 weeks postpartum.

This is more likely to be due to retained products of conception (RPOC) or infection (i.e. endometritis).

47
Q

Investigations for secondary post partum haemorrhage

A
  • Ultrasound for retained products of conception
  • Endocervical and high vaginal swabs for infection
48
Q

Managment of secondary post partum haemorrhage

A
  • Surgical evaluation of retained products of conception
  • Antibiotics for infection
