Postpartum Haemorrhage
Definitions
• Primary PPH –
blood loss of 500ml or more
within 24hours of delivery.
• Secondary PPH – significant blood loss
between 24 hours and 6
weeks after birth.
Why do we care?
Major obstetric haemorrhage – more than
1000ml
Very rapidly lead to maternal death
• 3rd highest cause of direct maternal death in
the UK and Ireland (2003-2005)
• 58% of these cases care was “seriously
substandard”
• Major cause of severe maternal morbidity in
“near-miss audits”
Risk Factors
Most cases have no risk factors

Previous PPH
Antepartum haemorrhage
Grand multiparity
Multiple pregnancy
Polyhydramnios
Fibroids
Placenta praevia
Prolonged labour (&oxytocin)
Prevention
• Be aware of risk factors – may present antenatally
or intrapartum
• Treat anaemia antenatally
• Active management of the 3rd stage
• Prophylactic oxytocics reduce the risk of PPH by
60% (oxytocin or oxytocin & ergometrine)
• 5IU IM for vaginal delivery
• 5IU IV for LSCS
• Consider oxytocin infusions

Perineal trauma
Operative delivery
Vaginal and cervical tears
Uterine rupture
• Blood loss is commonly underestimated
• Loss may be well-tolerated
• Beware the “trickle” and the “moderate
lochia”
• Minor PPH can easily progress to major PPH.
Management
• Has the placenta been delivered and is it
complete?
• Is the uterus well-contracted?
• Is the bleeding due to trauma?
Resuscitation
A & B – 10 -15l/min O2 by facemask
C2 14 gauge cannulae
blood for Hb, U&E, LFTs, clotting
crossmatch 4 units
2 litres of crystalloid rapidly
transfuse as soon as possible – consider O –
ve blood if any delays.

Haematological Management
•
•
•
•
DIC
Transfuse without delay
Involve haematology service at an early stage
Correct coagulopathy
Liase with consultant haematologist re use of
recombinant Factor V11 (Novoseven©) and
Fibrinogen.
• Traumatic for patient, family and staff.
• Debriefing for patient and staff.
• Case analysed to ensure care was of good
standard and any substandard care can be
improved.
Secondary PPH
•

•
Infection
Retained placenta
Trophoblastic disease
Antibiotics
Evacuation of retained products if bleeding
persistent or significant amount of tissue
retained.
