Answer

Routine preoperative investigations include the following [3] :

  • Full blood count (abnormalities corrected)

  • Clotting screen

  • Creatinine and electrolyte levels (abnormalities corrected and discussed with the anesthetist)

  • Liver function tests

  • Screening for methicillin-resistant Staphylococcus aureus

  • Chest radiography

  • Electrocardiography (ECG)

  • Echocardiography or ventriculography (to assess left ventricular [LV] function)

  • Coronary angiography (to define the extent and location of coronary artery disease [CAD])

A raised white blood cell (WBC) count should prompt a careful examination for any cause of infection. If possible, CABG should be postponed until infection has been excluded or treated. If the patient’s demographic characteristics (eg, age or smoking) indicate an increased risk of cancer, a gastrointestinal or urinary tract malignancy should be excluded.
