Epidural and spinal anaesthetics
Spinal anaesthetic
A spinal needle is a finer needle and involves one injection of anaesthetic drugs into
the spinal space and then the needle is removed. The advantage of a spinal
anaesthetic is that the onset of the anaesthetic is much faster and more complete.
It is only suitable for caesarean sections, not for ongoing analgesia during labour.
Epidural insertion
An intravenous line is inserted and administration of fluids commenced. This helps
to ensure your blood pressure remains within normal range. Your blood pressure will
be taken frequently after the epidural has been inserted. Some women experience
nausea and shivering after an epidural injection. This usually only lasts for a short
period of time.
You will be positioned either lying on your side or sitting up for the insertion of the epidural.
It is very important that you remain still during the insertion of the epidural. If you have
a contraction while the epidural is being inserted, tell the anaesthetist so that he/she can
wait for the contraction to pass before proceeding.
Following insertion of the epidural, a very thin tube called a catheter will be left in your
back so the anaesthetic can be topped up or attached to a continuous infusion pump,
or attached to a machine so that you have control of the dose yourself. The epidural
will take approximately 20 minutes to have its full effect and will be secured with tape
to your back.
An epidural can take away the sensation to pass urine. To keep your bladder empty,
you will need a urinary catheter (another thin tube) to drain your urine. You and your
baby will be continuously monitored by the electronic monitoring (CTG).Your blood
pressure will be monitored more closely by your midwife. You may still be able to feel
the urge to push but the sensation will be reduced.
Following the birth
We advise you not to attempt to get out of bed without assistance until the epidural
anaesthetic has fully worn off. Your midwife will assist you when you first mobilise.
Please do not attempt to get up or mobilise on your own. For your own safety, we ask
that you call the nurse call so supervision and assistance can be provided.
