Randomized Controlled Trial
[The calcium sensitizer levosimendan gives superior results to dobutamine in postoperative low cardiac output syndrome].
The use of levosimendan to treat postoperative low cardiac output syndrome (LCOS) has been studied in only small patient series and in randomized trials focusing on hemodynamic variables. The objective of the present study was to assess the effectiveness of levosimendan, compared with dobutamine, as a treatment for postoperative LCOS. ⋯ In this randomized study, levosimendan proved more effective than dobutamine. Postoperative morbidity and mortality were lower, fewer patients required either an additional inotropic drug, a vasopressor or intra-aortic balloon counterpulsation, and the length of stay in intensive care was shorter.
