Study to Determine if Pre- and Post- Operative TAP Catheters With Ropivacaine Versus Placebo Affects Anesthetic, Narcotic Dosing, and Pain Scores

A randomized controlled trial to determine if pre- and post- operative regional pain control (transversus abdominis plane block) with ropivacaine versus placebo leads to lower anesthetic and narcotic dosing, and alters pain scores. This study plans to learn more about regional anesthesia and pain control during abdominal surgery. The study will gather data about the effectiveness of continuous catheter infusion of local anesthetic after an abdominal operation. Outcomes include pain scores, IV pain medicine requirements, and delirium.
