Intra-op Lidocaine and Ketamine Effect on Postoperative Bowel Function

• Status: Terminated
• Trial end date: 2006-11-01
• Target enrollment: 0
• Participant gender: All

Summary

Bowel function after bowel surgery is delayed (postoperative ileus)by both opiates and the surgery itself. We hypothesized that decreasing opiate use by other analgesics will speed the return of bowel function after surgery. Lidocaine and Ketamine are drugs that appear to be synergistic and do not slow peristalsis. This study is a Randomised Controlled Trial of Lidocaine Infusion Plus Ketamine Injection versus Placebo to to determine whether they will decrease opiate use and then whether decreased opiate use will speed the return of bowel function.
