Spinal anaesthesia is now practised widely. This article is not intended to be an exhaustive review; it will focus on some new developments and techniques.

Key points

Reduction in spinal needle size has significantly reduced the incidence of post-dural puncture headache, but failure rates increase with needles of 29G or smaller.

Newer needle designs may be associated with a higher rate of successful identification of the subarachnoid space, faster CSF backflow and fewer neurological symptoms than standard 25G Whitacre needles.

Both ropivacaine and levobupivacaine have been used successfully for spinal anaesthesia, but glucose-free solutions produce sensory block of variable extent.
