Study Summary
The purpose of this study is to compare postoperative pain control after minimally invasive coronary artery bypass grafting for patients who receive an intercostal block (an anesthetic medicine injected in an area under the ribs) in the operating room and IV acetaminophen (Tylenol) to those who receive an intercostal block and On-Q pain pump catheter (a balloon pump attached to 2 small tubes near your procedure site that automatically delivers pain medicine).
Primary Outcome
Pain scores will be assessed using a Numerical Rating Scale (NRS) (an 11-point scale, 0 through 10, with 0 representing 'No pain' and 10 representing 'Worst imaginable pain'). Pain scores will be entered by nursing staff every 2 hours in ICU, and every 6 hours on the floor for the duration of the hospital stay, an expected average of 4 days.
Interventions
