This is a double-blind, randomized, placebo-controlled trial to examine the effectiveness of adding one 25mg dose of naloxegol to the cardiac surgery pre-op regimen. There will be 140 subjects per study group. The patient and treating physician/nurse will be blinded as to which group the subject is assigned. On the day of surgery, subjects in both groups will complete a questionnaire to assess compliance with prescribed pre-operative regimen. Subjects in both groups will receive post-operative bowel regimen in the cardiovascular intensive care unit (CVICU) according to current standard of care, including procedures for rescue medications for constipation prevention and induction of a bowel movement.
