Prolonged intensive care unit stay after coronary artery bypass graft surgery: Role of perioperative factors.

Introduction: Long stay in the Intensive Care Unit (ICU) after coronary artery bypass graft (CABG) surgery has been found to result in increased hospital mortality, poor long-term prognosis, prolonged hospital stay, and consequently, high cost and expenses. We, therefore, reviewed CABG surgery performed at the Madras Medical Mission Chennai, India, during a 3-month period to determine perioperative factors that are significant predictors of prolonged ICU admission.

Methods: We retrospectively studied patients who had elective CABG surgery from November 2008 to January 2009.
