Sometimes, the doctor may
need to start labour artificially after weighing the risk of
delivery for the
mother and the baby as compared to the risk of continuing pregnancy.
These methods are also
adopted to speed up labour that is not progressing well. Before
deciding to induce labour, the
doctor will do foetal monitoring and determine if the mothers
cervix is favorable for induction.
In certain cases it is
left to the doctor to decide whether to deliver you artificially.
Methods
of induction of labour
* |
Artificial
rupture of membranes: In prolonged labour, the
membranes which holds the bag
of water is pierced via the vaginal route, allowing some
of the amniotic fluid to escape, which
alters the pressure in the womb causing labour to start. |
* |
Oxytocin
drip: A synthetic hormone oxytocin is given by
intravenous infusion, which is carefully
monitored. These help to bring on contractions or make
them stronger and start or assist
labour. |
* |
Prostaglandin
gel or tablet: Is put in the vagina to start labour pains. |
Methods of assisting labour in later stages
When for some
reason the foetal heart beat becomes irregular or the
baby's position makes the
delivery difficult the mother is too tired to push, the doctor
may use one of the following :
* |
Forceps:
A surgical
instrument looking like two big spoons is passed around
the babies head
in the birth canal, mostly at the outlet and occasionally
at a little higher level, to gently pull
out the baby. |
* |
Vacuum
Extraction: A
plastic cup is attached to the baby's head and by using
a vacuum pump
the baby is gently pulled from the birth canal. |
* |
Caesarian
Delivery: Delivering
the baby via abdomen route when delivery via the vaginal
route is not safe
for the baby, which may happen unexpectedly,
an emergency Caesarian delivery
is done e.g. conditions of foetal distress, placental
problems with bleeding. Sometimes a Caesarian birth may
be planned well in advance, for reasons such as: |
• |
CPD (cephalopelvic disproportion) where baby is too large
to pass safely through the mother's
pelvis. |
• |
Medical
illness of the mother like diabetes and blood pressure. |
• |
Breech presentation of the baby (buttocks and feet are
placed first instead of the head,
as baby emerges from the birth canal) or other unusual
presentation. |
