Reposição Volêmica Intraoperatória: Cristaloides versus Coloides em Revascularização Cirúrgica do Miocárdio sem Circulação Extracorpórea * Intraoperative Volume Replacement: Crystalloids versus Colloids in Surgical Myocardial Revascularization without Cardiopulmonary Bypass

SUMMARY Soares RR, Ferber L, Lorentz MN, Soldati MT – Intraoperative Volu-me Replacement: Crystalloids versus Colloids in Surgical MyocardialRevascularization without Cardiopulmonary Bypass. BACKGROUND AND OBJECTIVES: The use of crystalloids orcolloids for volume replacement in large size surgeries iscontroversial. The objective of this study was to compare the effectsof the intraoperative administration of crystalloids (normal saline –NS) with those of colloids (modified fluid gelatin) for surgicalmyocardial revascularization (SMR) without cardiopulmonarybypass (CPB). METHODS: Forty patients undergoing SMR without CPB wererandomly divided in two similar groups. The first group receivedmodified fluid gelatin and NS and the second group received onlyNS. Urine output, hemoglobin level, intra- and postoperative blee-ding, blood glucose levels, and intraoperative lactate in four distinctmeasurements were recorded. Postoperative morbidity and mortality,length of stay in the intensive care unit (ICU), and length of hos-pitalization were analyzed.
