Preoperative Pain Neuroscience Education in Patients Undergoing CABG

This randomized controlled trial evaluated the effects of a single preoperative pain neuroscience education (PNE) session on postoperative pain-related outcomes in patients undergoing elective coronary artery bypass grafting (CABG). Participants were randomly allocated to either a PNE group, which received a structured preoperative PNE session in addition to routine preoperative care, or a control group, which received routine preoperative information and care. Outcomes included pain intensity, pain catastrophizing, pain vigilance and awareness, and pressure pain threshold. Assessments were conducted preoperatively and at 24 hours, 1 month, and 3 months after surgery.
