Effect of adding ketorolac to intravenous morphine patient‐controlled analgesia on bowel function in colorectal surgery patients – a prospective, randomized, double‐blind study

Abstract

The results of this study suggest that addition of ketorolac to intravenous morphine PCA provides an opioid-sparing effect but has limited benefit in shortening the duration of bowel immobility and time to first ambulation. These findings imply that postoperative ileus is attributable to multiple factors in addition to morphine consumption.
