This is my 5th morphine /dilaudid pump. Installed in February of this year. By May it was noticed that the surgical site was infected. They opened me up and found staph infection. They flushed out the pocket and gave me IV antibiotic. Sent me home with oral antibiotic. This month, August 13th, they opened me up again and found more infection so they removed the pump and catheter and again flushed out the affected areas. What percentage of people go back on the pump successfully without the return of infection?
