Summary Paravertebral analgesia is highly effective in blocking unilateral afferent input from the trunk, but its bilateral use does not appear to have been described. Eight patients undergoing major abdominal vascular surgery had pre‐operative bilateral paravertebral catheters inserted. A dose of 25 ml of bupivacaine 0.5% divided between the two catheters provided the basis of an effective intra‐operative analgesic regimen which was continued postoperatively by infusion of bupivacaine for 4 days. Diclofenac and morphine completed a balanced analgesic regimen which was started pre‐operatively and continued for 5 and 3 days respectively. Cardiovascular stability was notable throughout surgery, even with aortic clamping and all patients were extubated at the end of surgery. Good quality analgesia was obtained as assessed by low postoperative pain scores at rest and on movement. Three patients were not admitted to the intensive care unit, where mean stays for the group was 10 h (range 0‐24 h) and mean hospital stay was 10 days (range 7–14). There were no additional demands made on the nursing staff and no postoperative pain‐related complications occurred. We conclude that bilateral paravertebral analgesia, as part of a balanced analgesic technique, is an alternative method of providing effective afferent blockage for major abdominal surgery.
