title: Bacteremia following prosthetic valve replacement.
abstract: The outcome of patients developing early bacteremia was investigated in 890 patients following cardiac valve replacement over a ten-year period. Thirty-two patients developed bacteremia during the hospital recovery period from valve replacement (3.6%). Sixty per cent of the organisms involved were gram-negative. Twenty-one of 23 patients had white blood counts greater than 14,000 at the time of positive blood culture. Nine patients died, seven of septic complications. Only two patients developed endocarditis. No patient with bacteremia diagnosed within ten days of surgery developed endocarditis, however two patients developed gram-negative sepsis in this period. The diagnosis and treatment of bacteremia requires continual vigilance if significant mortality and morbidity are to be averted.
