Epidural analgesia in labour aims to provide high-quality pain relief of rapid onset and prolonged duration, while minimizing both maternal side-effects, particularly impairment of mobility, and impact on the fetus or on the outcome of labour. In conjunction with pharmacological research on spinal analgesics (local anaesthetics, opioids and other drug classes), refinement of new or established drug delivery techniques has allowed progress toward more reliable and improved pain relief at all stages of labour and childbirth, reduced individual drug doses with reduction of unwanted effects and greater safety and enhancement of maternal satisfaction. Patient-controlled epidural analgesia in labour has been in use for almost a decade, although is only now at a stage where its role is well defined and utility can be increased. Combined spinal-epidural analgesia is a more recent refinement which appears to be extremely promising but awaits further investigation.
