| Popis: | Data on 14, 168 adult patients undergoing surgery in the 44 months from November 1, 1975 to July 1, 1979 were analyzed to determine the incidence of need for escalating degrees of mechanical support of the failing circulation (intraaortic balloon pump, abdominal left ventricular assist device, or both) after cardiopulmonary bypass. Analyses were performed using a TRS-80 microcomputer to categorize the postoperative course of all adult patients undergoing open heart surgery. It was assumed that any patient who died despite pharmacologic and intraaortic balloon support was a candidate for more profound mechanical circulatory support, that is, the left ventricular assist device, which is 6 to 10 times more hemodynamically effective; on this basis, the latter device was needed in 430 cases (3 percent). A total of 12,669 patients (89.4 percent) were weaned from bypass without difficulty, 1,499 patients (10.6 percent) required pharmacologic agents and volume loading during weaning, 326 patients (2.3 percent) demonstrated inadequate responses to conventional pharmacologic therapy and required intraaortic balloon support during weaning, 94 patients (0.7 percent) demonstrated an inadequate response to conventional pharmacologic and balloon support and 21 patients (0.1 percent) underwent profound mechanical circulatory support (abdominal implantation of a left ventricular assist device). |
