Bleeding after childbirth.
Causes
|
There are many cases where complications
are presented in an unexpected manner by
which the appropriate care depends on
the immediate identification and
appropriate treatment. The key to
success is to recognize these
complications in patients at risk and
take precautions to avoid these
problems.
Bleeding after vaginal or caesarean
section is one of the most common
complications and their causes may be:
pre-eclampsia, birth of twins,
prolonged, laceration of the soft
tissues, use of forceps during delivery,
infection in the uterus .
Episiotomy (cut is made in the normal
output to help prevent fetal and
maternal tears) may be made to the
medial (toward the anus) or in a half
lateral (sideways direction), this
latter is more bleeding associated with
abundant, are more painful and have more
difficulty in healing than in the medial
cut. By contrast half episiotomy
increases the risk of spreading the
court and injuring the rectum.
The use of forceps during delivery is
another cause related to bleeding after
childbirth, and the use of this
instrument depends on the approach,
skills and experience of the doctor.
Post partum hemorrhage occurs mainly by
two mechanisms: first by the lack of
contractility of the uterus to compress
the blood vessels and bleeding by the
second flaw in the system of blood
clotting.
The lack of contractility of the uterus
is called uterine atony, which can be
caused by the presence of remnants of
the placenta inside the uterus after
childbirth; exaggerated distention of
the uterus, either by multiple pregnancy
or excess fluid anmiótico ; precipitate
or forceps delivery, use of certain
drugs during labor and physical activity
after childbirth (eg household chores)
The retention of the placenta is another
cause of bleeding after childbirth, as
is the placenta which is firmly attached
to the uterus (placenta accreta), the
latter occurs more often in women who
have had previous Caesareans.
Also lead to post partum hemorrhage
rupture of the uterus by intense and
prolonged contractions, and uterine
inversion, which are serious and require
immediate correction.
