Dear friend, welcome and thanks for entrusting your query here at Healthcaremagic!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
No, it is not common after a routine CABG (bypass surgery
). The chest is kept open if there are complications or ongoing or possible bleeding.
If it was really a 14 hour surgery, it is not routine surgery.
As you said rightly, prognosis depends on lot of factors. What surgery was done? What was the problem?
How was his health condition before?
We need lot of data to recommend something online.
In general, the impression about prognosis is not good.
I hope to have given you some good idea.
Please ask for any clarifications before closing and rating this answer.
