[Intraoperative volume replacement: crystalloids versus colloids in surgical myocardial revascularization without cardiopulmonary bypass].

Background And Objectives: The use of crystalloids or colloids for volume replacement in large size surgeries is controversial. The objective of this study was to compare the effects of the intraoperative administration of crystalloids (normal saline - NS) with those of colloids (modified fluid gelatin) for surgical myocardial revascularization (SMR) without cardiopulmonary bypass (CPB).

Methods: Forty patients undergoing SMR without CPB were randomly divided in two similar groups.
