Notes:
From July 1996 to March 2000, 391 patients with intraoperative cardiac lowoutput syndrome who underwent surgery with heart-lung bypass and had an intre-aortic balloon pump (IABP) Implanted were analyzed in a prospective study. Of these 391 patients, 153 (39%) were operated on in an emergency situation, and 238 (61%) patients had elective surgeries. The perioperative mortality was 34% (133 patients). Clinical parameters were analyzed 1 hour after IABP support began. Statistical multivariate analysis showed that patients with an adrenaline requirement higher than 0.5 μg/kg/min, a left mrial pressure higher then 15 mmHg, output of less than 100 mL/hour, and mixed venous saturation (SvO2) of less then 60% had poor outcomes. Using this data, we developed an IABP score to predict survival early after IABP implantation in cardiac surgery. We conclude that the success or failure of perioperative IABP support can be predicted early after implantation of the balloon pump. In patients with low-output syndrome despite IABP support, implantation of a vantricular assist system should be considered.
