Primary outcomePrimary: Postoperative Numerical Pain Score-Day 0 — 3.9; 2.6 units on a scale
Summary
This is a prospective randomized study of 114 patients. The purpose of this study is to compare the efficacy of two standard methods of analgesia for pain control in patients undergoing elective colon and rectal surgery, as measured by the Numeric Pain Scale (NPS) and by the need for supplemental narcotic analgesics. This study is designed to determine if postoperative pain control by local analgesics delivered through preperitoneally placed ON-Q Silver Soaker™ catheters (CPA) is equivalent to continuous epidural analgesia (CEA).
