Primary postpartum haemorrhage
A primary postpartum haemorrhage is defined blood
loss of over 600 ml within the first 24 hours after the baby is born (or if the
woman is quite physically affected after a ‘normal’ blood loss). This is the
most common type of postpartum haemorrhage, complicating up to 6% of all
births.
loss of over 600 ml within the first 24 hours after the baby is born (or if the
woman is quite physically affected after a ‘normal’ blood loss). This is the
most common type of postpartum haemorrhage, complicating up to 6% of all
births.
The amount of blood lost can be all at once (which
is the most common, usually within the first hour after the baby is born) or
accumulate over a period of time. For example a woman may lose 300 ml with the
birth, then an hour later a further 200 ml, then a few hours later 300 ml,
meaning that she is now classified as having had a primary postpartum
haemorrhage (Bias, et al., 2010).

Secondary postpartum haemorrhage
A secondary postpartum haemorrhage is when more
than 600ml of blood is lost after 24 hours but up to 6 weeks after the birth of
the baby. This type of haemorrhage is much less common, occurring in less than
1% of all births.

The amount of blood lost in a secondary haemorrhage
is not generally added to the amount lost within the first 24 hours after the
birth. The reasons for a secondary postpartum haemorrhage are normally related
to either an infection of the uterus or part of the placenta being retained and
causing an infection (Bias, et al., 2010).
