Patent number: 6261582Abstract: Administration of a morphine-based analgesic paste directly to the epidural space during lumbar decompressive surgery significantly improves post-operative pain control, reduces prescribed analgesic consumption, and improves overall health perception for a period of up to 6 weeks following surgery. In a series of 60 patients no treatment related complications attributable to the paste were observed. This post-operative pain control strategy may provide a new gold-standard of care patients undergoing lumbar disectomy or laminectomy.Type: GrantFiled: May 29, 1998Date of Patent: July 17, 2001Assignee: C.
