Preventive Narrative Exposure Intervention for PTSD in ICU Patients After Cardiopulmonary Bypass Cardiac Surgery (ICU-pNET)
Effects of Preventive Narrative Exposure Intervention on Posttraumatic Stress Disorder Among ICU Patients After Cardiopulmonary Bypass Cardiac Surgery: A Randomized Controlled Trial
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.

Descripción detallada
Patients admitted to the intensive care unit after cardiac surgery with cardiopulmonary bypass may experience stressful events such as mechanical ventilation, invasive procedures, physical restriction, noise from monitoring devices, sleep disturbance, and uncertainty about their condition. These experiences may lead to fragmented ICU memories, gaps in factual understanding, frightening or unreal memories, and a persistent sense of threat after discharge. These factors may increase the risk of posttraumatic stress symptoms.
Existing supportive approaches, such as routine psychological education or ICU diaries, may help patients obtain factual information and emotional support. However, they may not sufficiently support patients in actively organizing and processing stressful ICU-related memories. Therefore, this study will test an ICU-based preventive narrative exposure intervention designed for patients after cardiopulmonary bypass cardiac surgery.
The intervention is delivered during the perioperative and early recovery period. It uses an ICU visitor book as a narrative support tool. The visitor book contains selected and privacy-protected photos, family messages, and key recovery events. These materials are used to help patients reconstruct the timeline of their ICU experience, understand what happened during treatment, and narrate stressful events in a guided and structured way. The intervention also includes brief education about stress reactions, grounding strategies, review of ICU experiences, and integration of the experience before discharge.
The intervention is preventive rather than therapeutic treatment for diagnosed posttraumatic stress disorder. It is intended to help patients form a more coherent and understandable account of their ICU experience, reduce distress related to fragmented or frightening memories, and support psychological recovery after cardiac surgery.
