Summary

This study will randomise pregnant women to labour epidural at a higher versus a lower lumbar level. Outcomes relating to success or failure of the epidural catheter at this level will be assessed.

Detailed description

Epidural analgesia is widely used in different types of surgeries and procedures. Pregnant women in labour compromise the single largest group benefiting from epidural analgesia. During first stage of labour (dilatation of the cervix), an epidural should cover the sensory dermatomes from T10 to L1 to achieve a good pain relief. In the second stage of labour (descent of the baby through the cervical canal), pain is mediated via S2-S4 nerve roots. Accordingly, labour epidurals are commonly placed at the lower lumbar (L3-L4) interspace.1 A study was conducted by Moore et al., comparing high vs low lumbar epidural, showed that lower epidurals provide superior perineal analgesia, when used with a patient-controlled epidural analgesia (PCEA) infusion with continuous epidural infusion (CEI), but provided less pain relief early in labour. Another study, a metanalysis showed that another mode of delivery of the local anaesthetics is more effective; which is the Programmed Intermittent Epidural Boluses (PIEB) with PCEA. The incidence of breakthrough pain, the rates of local anaesthetic usage were significantly reduced, the labour duration was statistically shorter, and the maternal satisfaction score was significantly improved in the PIEB + PCEA group compared with that in the CEI + PCEA group. This is a prospective randomised study where women will be randomised to a high or low epidural catheter to determine which is superior for maternal analgesia efficacy and satisfaction. Randomised to intervention 'high epidural' or 'low epidural' groups. Within these groups there are two subgroups based on the specific lumbar vertebral level; high epidural (L 1,2 or L 2,3 levels) and low epidural (L 3,4 or L 4,5 levels).
