Wong et al developed 3 cardiac risk scores for patients undergoing coronary artery bypass graft (CABG) surgery. One of these helped to identify a patient who may have delayed extubation (prolonged intubation). The authors are from the University of Toronto.
Parameters:
(1) age in years
(2) gender
(3) bleeding after surgery
(4) intra-aortic balloon pump
(5) therapy with inotropes
(6) atrial arrhythmia

total score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: 0
• maximum score: 21
• The higher the score the greater the risk of delayed extubation.
