RESUMO
UNLABELLED: We prospectively compared, the glucose-insulin-potassium (GIK) solution 1,000 mL 10% glucose, 20 units of fast acting insulin and 60 mEq of potassium chloride, against a GIK solution with 1,000 mL of glucose, 40 units of fast acting insulin an 120 mEq of chloride, in the hyperglycemic control of non-diabetic patient subjected to cardiac surgery. We divided 40 patients in four groups ten patients each. Group A was the control they received 1,000 mL of 10% glucose in water, 20 units of fast acting insulin and 60 mEq of potassium chloride in a drops/ hour dose without an infusion pump. Group B received the same solution in a 50 mL/hour dose. Group C received 1,000 mL of 10% glucose in water, 40 units of fast acting insulin plus, 120 mEq of potassium chloride at the same infusion rate as Group A. Group D 2 1,000 mL of 10% of glucose in water, 40 units of fast acting insulin in the same rate as Group B. The GIK solution was started after anesthesia induction and maintained all along the extracorporeal circulation, the study continued until the patient was transferred to the intensive care unit. We measured blood glucose, circulating insulin and seric levels of potassium three times; basal before the anesthetic induction, during the extracorporeal circulation and at the intensive care unit arrival. The data were analyzed with measure of central tendency, dispersion and multivariate analysis. RESULTS: Among the four groups no statistically significant differences existed in demographic data. In Group A, glucose and potassium levels were higher as compared with the rest of the groups (p <0.05) in all measurements; Group D was less hyperglycaemic as compared with Groups A, B, and C. CONCLUSION: The solution with low insulin dose does useful plasmatic insulin levels in the hyperglycemia in non diabetic patients subjected to cardiac surgery.

UNLABELLED: The purpose of this work was to observe the hemodynamic stability on the first 24 hours in 4 patients with ventricular dysfunction (Ejected Fraction < 40 %), considered of high surgical risk, in which 24 at 48 hr before the surgery received an infusion of Levosimendan for 24 hours. This 4 patients was male, with age 55.5+/-7.9 years old, a left ventricle ejection of fraction (LVEF) of 31+/-5.47%; Two of them was underwent to valve replacement, another one to coronary artery bypass graft and the last one patient underwent combined procedure (coronary artery bypass graft surgery and valve replacement). The behavior of the hemodynamic parameters was stable, without necessity of uses high dose of the inotropios and classic vasopresores in the postoperative. CONCLUSION: the Levosimendan could be an inotropic of great application in this group of patient due to its novel action mechanism and to its sustained hemodynamic effects after having finished its infusion.
