Spinal Anaesthetic
A spinal anaesthetic is the injection of a local anaesthetic into
the lower part of the mother's back (into the subarachnoid space).
Unlike the epidural anaesthetic, this method involves injecting the
anaesthetic directly into the space, and no catheter is needed.
Advantages:
- Has an immediate effect and is almost 100% effective in
relieving pain.
- There are minimal side-effects when administered correctly.
- Can be used for a Caesarean section.
Disadvantages:
- A spinal wears off more quickly than a epidural does, so it
would be of no use in those women experiencing a long labour.
- There is a risk of a fall in the mothers' blood pressure,
which in turn may reduce the oxygen supply to the baby.
- If a small amount of spinal fluid happens to leak out in the
process, it could cause violent headaches.
