Background. In cardiac surgery, inotropic drugs are used frequently. It is important to anályze the effects of these drugs and the possibility to increase adverse outcomes when they are used incorrectly. The purpose of this study was to describe the inotropic requirement predictors. It pretends to reduce the use of these drugs in patients that do not need them.methods. We anályzed patient files who underwent surgery between September 2005 and January 2007 in the Calderón Guardia Hospital in San José, Costa Rica. They voere 119 patients. Results. There was no difference in the use of inotropes rélated to age, sex, concomitant diseases, surgicál diagnosis, surgery perform or anesthesiologist. The previous history of cardiac infarction, the number of them or the time between the surgery and the last one were not related to the inotropic requirement. There was no relation between the American Society of Anesthesilogists score and the need of inotropic support; but a higher New York Heart Association score had a positive relation with the use of inotropes. The duration of the aortic clamp and the surgery time were also related with the need of inotropic support. The time of extracorporeal circulation had no relation with the need of inotropic drugs. There was a higher need for inotropic support in patients with a positive liquid balance and in patients with intraaortic balloon pulsation. The ejection fraction was a predictor of the need of inotropic drugs. Conclusion. There are some variables related to a greater need of inotropics drugs.
