How long should it take to get over open heart surgery with a staph infection?

It really depends: A staph infection can include so many things. This can range from a surgical wound infection, a lung infection (pneumonia), a urine infection, and even skin where no surgery was done. The worst case would probably be an infection of the breast bone. This often requires multiple surgeries to treat and will prolong your recovery several months. Fortunately, this is a rare complication of surgery.

That depends: A sternal wound infection is very serious, even if the bone is preserved. Generally an infection requires a long course of antibiotics, and the bone may need to be debrided and the chest reconstructed. Some respond quickly if the infection is minor - a major infection can take months to get over. The internet is not the best place to get answers - always remember to talk to your doctor.

Varies: Depends on the site of infection (mediastinum, sternum, superficial soft tissue, vein harvest site, central line, lung, bladder, etc), immunosuppression, nutrition, and treatment.
