L’effet de l’extubation precoce apres chirurgie cardiaque pour la rehabilitation post opératoire

Abstract

Introduction: Postoperative rehabilitation after cardiac surgery is based on medical-surgical management in order to reduce the lenght of stay in hospital and the costs of this high risk surgery. Early tracheal extubation (within the first 6 hours) is the cornerstone of fast-track surgery. Our study aimed to evaluate fast-track practice and early tracheal extubation in scheduled cardiac surgery for adult patients in our Institution. Methods: We conducted a descriptive study including all patients aged over 18 years who consecutively had undergone scheduled cardiac surgery and postoperative treatment in the post-operative intensive care unit in the Department of Thoracic and Cardiovascular Surgery at the Habib Bourguiba University Hospital, Sfax. Inclusion criteria were: patients aged 18 years and older who had undergone scheduled cardiac surgery and postoperative treatment in the post-operative intensive care unit in the Department of Thoracic and Cardiovascular Surgery. Standardized anaesthetic protocol was used in all cases: propofol, remifentanil, cisatracrium. We recorded the mean postoperative extubation time and the factors affecting extubation time. Results: We collected data from 200 patients who consecutively had undergone scheduled cardiac surgery. Among these patients, 115 underwent coronary artery bypass surgery, 79 valvular surgery and 6 combined surgery or another surgical procedure. Patients’ demographic characteristics were comparable. 152 patients (76%) underwent postoperative extubation within the first 6 hours. 48 patients couldn’t be extubated within the FIrst 6 hours. The main causes of early extubation failure were: catecholamines in high doses, bleeding, arrhythmia and neurological disorders. Conclusion: Our study demonstrates that postoperative rehabilitation can be performed in our Institution and that all patients undergoing scheduled cardiac surgery should be candidates for early extubation.
