When comparing spinal block and epidural block groups, spinal block is simpler, easier and more reliable and it is useful for urgent Caesarean sections because of its rapid onset. In the spinal group, 0.4 per cent heavy bupivacaine is more reliable than 0.5 per cent plain bupivacaine. Spinal lidocaine can also be used for Caesarean section requiring an operation time of not more than 1 hour. If the operation time is expected to be more than an hour, spinal block with 0.4 per cent heavy is preferred. In epidural block with 2 per cent lidocaine (20 ml) time to get to T4 was more than 20 minutes after block and failure rate was higher. It should then be used in elective cases and by an experienced anesthesiologist.
