Preventive Narrative Exposure Intervention for PTSD in ICU Patients After Cardiopulmonary Bypass Cardiac Surgery

This clinical trial aims to evaluate whether an ICU-based preventive narrative exposure intervention can help prevent posttraumatic stress symptoms in adult patients after cardiac surgery with cardiopulmonary bypass. The study will include adult patients who undergo cardiac surgery with cardiopulmonary bypass and are admitted to the cardiac surgical intensive care unit. Participants will be randomly assigned to either the intervention group or the control group. Participants in the control group will receive routine care and routine psychological support. Participants in the intervention group will receive routine care plus an ICU-based preventive narrative exposure intervention supported by an ICU visitor book. The intervention includes preoperative education, review of ICU experiences, construction of a timeline, guided narration of stressful ICU-related events, and integration of the experience before discharge. The ICU visitor book includes selected photos, family messages, and key recovery events. It is used to help patients better understand and organize their ICU experience. Researchers will compare the intervention group with the control group to see whether the intervention reduces posttraumatic stress symptoms. The primary outcome is posttraumatic stress symptoms at 1 month after discharge. Secondary outcomes include posttraumatic stress symptoms at 3 months after discharge, ICU memories, anxiety, depression, sleep quality, quality of life, and patient and family satisfaction with ICU care. The findings may provide evidence for an early psychological nursing intervention to prevent posttraumatic stress disorder in ICU patients after cardiopulmonary bypass cardiac surgery.
