Bupivacaine infiltration after lumbar laminectomy. Local infiltration in the control of early postoperative lumbar laminectomy pain.

This is a report of a double-bind controlled trial to test the hypothesis that peroperative local infiltration of the wound of lumbar laminectomy with bupivacaine produces a significant reduction in postoperative back pain. No such effect was demonstrated when the linear analogue was used to record the patients' subjective response to pain. It is suggested that this treatment is not indicated as a routine method.
