During intensive care unit stay

Physician-led weaning

Haemodynamically stable patients aged over 18 years, receiving mechanical ventilation support after elective coronary arterial bypass grafting will be consecutively included. Written informed consent will be obtained from each patient before surgery.

Preoperative exclusion criteria: patients older than 80 years or younger than 18 years, acute or chronic obstructive pulmonary disease (primary indication for ventilation), and concomitant valvular and/or aortic surgeries, major organ failure (liver disease, renal failure), history of seizure or stoke are excluded preoperatively.

Postoperative exclusion criteria: Severe early postoperative haemorrhage (chest tube drainage >500 ml/h), surgical complications needing reoperation, myocardial ischemia (ST-segment depression) lasting more than 30 min, postoperative cardiac failure necessitating high-dose inotropes or intra aortic balloon pump; refractory hypoxemia (ratio of arterial oxygen tension [PaO2] to fraction of inspired oxygen [FIO2] < 150 mmHg)
