Cardiovascular responses to systemic bacteremia were evaluated in a pre-instrumented, conscious pigs. Basal observations were obtained 5-7 days after instrumentation. On the next day, Escherichia coli 0111.B4 (1.1 to 33 × 109 CFU/kg)-laden fibrin clots were implanted intraperitoneally. Nonsurvivors (9/18) demonstrated rapid cardiovascular decompensation. Survivors (9/18) demonstrated significant cardiovascular injury, which was reversed by 5-7 days postimplant. Cardiac inotropicity was significantly reduced in this period, but recovered by day 7. Circulating myocardial depressant substance activity (assayed by serum-induced depression of beating neonatal rat myocytes) was present on days 1-4 of bacteremia and recovered to basal values on day 6. No clinical or cardiovascular changes were seen in pigs implanted with sterile clots (n = 4). These data demonstrate that implantation of bacteria-laden fibrin clots in pigs induces cardiovascular alterations that mimic responses seen in human sepsis. f.
