Lumbar epidural block was given for pain relief to 296 women in labour. Bupivacaine was used as the analgesic agent and the technique is described in detail. Satisfactory analgesia was obtained in 92% of the cases during the first stage of labour and in 84% during the second stage of labour. The frequency of instrumental deliveries and of occipitio-posterior position increased but the clinical condition of the newborn seemed to be unaffected.
