Postoperative chronic pain incidence and etiology in coronary artery bypass graft surgery: a prospective study

Abstract

Introduction: Post-operative chronic pain (POCP), after updated by Werner-Kongsgaard, is defined as the pain developed after the surgical procedure or increased in intensity after the procedure, as the continuation of acute postoperative pain, localized in the surgical area, lasted at least 3 months, and other causes of pain excluded. In our study, we aimed to prospectively examine the prevalence of POCP and risk factors in the first three months after coronary artery bypass graft surgery (CABGS).
