Post delivery bleeding may sometimes turn into
haemorrhage. Are you aware of the causes of post delivery haemorrhage? Read on
to know more about the common causes of post delivery haemorrhage.
In simple terms, when there is a loss of
500ml or more blood within the first twenty-four hours of delivery, it is known
delivery haemorrhage. This happens in 18%
of births across the world. It is an unfortunate condition as doctors do take
into consideration the risk factors and are armed with the preventive
strategies but in certain cases, the haemorrhage happens to be unexpected and
is actually unavoidable. Given below are the common broad reasons that lead to post
This is found to be the most common
cause of post delivery haemorrhage, in around 70% of the cases. In otherwise
normal conditions, the uterus contracts to its earlier size after delivery.
Ideally, the myometrial contraction takes place and this in turn results in the
separation of the placenta and the gradual constriction of the blood vessels.
When these factors follow one another, a retroplacental clot is created and the
bleeding from the placental bed is stopped, when the separation of the placenta
Uterine atony refers to the state when
the uterine contraction does not happen following the birth of the baby.
So, the entire process is stopped due to uterine atony and the woman is exposed
to severe blood loss. This condition can be effectively dealt with through the administration
of certain uterotonic drugs like oxytocin and misoprostol during the third
stage of labour.
This condition is a reference to the
tearing or laceration of the genital tract during childbirth.
Considered to the second most common cause leading to post delivery
haemorrhage, which approximately amounts to twenty percent, trauma is also a
condition that involves uterine inversion and uterine rupture.
The tearing can happen in three stages:
cervical, perennial or vaginal. But according to various studies of cases, the
exact site of bleeding often is very difficult to detect. This makes it
extremely difficult for the physician to prevent and control the bleeding.
Precisely this is one of the reasons why trauma is said to be more difficult to
deal with in comparison to atony. In most cases, it is found that balloon
tamponades were effectively used to bleeding resulting from vaginal laceration.
Blood clots and retention of certain
products that constitute tissues result in almost ten percent of the post
delivery haemorrhages. In most of the cases, it follows due to the retention of
the placenta. The possible causes leading to this condition can be detected and
taken care of by extensive examination of the placenta, a proper exploration of
the uterine cavity and finally by manually removing the retained tissue. A
timely surgical management can effectively deal with this less serious post
delivery haemorrhage cause.
This condition is defined by an abnormal
coagulation process in the woman, whereby, the normal activity of blood
clotting is disrupted or does not happen at all. This is a very uncommon cause
of post delivery haemorrhage. The deficiency needs to be identified at first
and the clotting factor replacement must be arranged in time. With early recognition
and proper evaluation, which includes timely treatment, the potential severe
outcomes of this reason of post delivery haemorrhage can be effectively dealt
with. Immediate fluid resuscitation is very important.
There are new
technologies and practices evolving everyday in the medical world which can
efficiently deal with these four principal causes of post delivery haemorrhage
leading to maternal mortality. As stated above, atony and trauma constitute
around ninety percent of maternal deaths, while the latter two are less common.
