Success rates were 82·3% in lateral pre‐iliac – lumbar paravertebral sciatic nerve and 74·7% in dorsal paravertebral – sciatic nerve groups. Bupivacaine, levobupivacaine and ropivacaine were used. Total local anaesthetic doses, intraoperative hypotension and postoperative methadone administered were similar between groups; minimum alveolar concentration multiple was significantly (P<0·001) lower in lateral pre‐iliac – lumbar paravertebral sciatic nerve group.
