BackgroundThe aim of the study was to evaluate the effect of hypertonic NaCl hydroxyethyl starch solution on haemodynamics and cardiovascular parameters in the early postoperative period in patients for correction of hypovolaemia after heart surgery.MethodsEighty patients undergoing myocardial revascularisation at the Clinic of Cardiac Surgery of the Heart Centre (Kaunas University of Medicine) were randomly divided into two groups. The HyperHaes group (n = 40) received 250ml 7.2% NaCl/6% HES solution and the control Ringer's acetate group (n = 40) received placebo (500 ml Ringer's acetate solution) for volume correction after the surgery.ResultsAfter infusion of HyperHaes solution, cardiac index increased from 2.69 (0.7) to 3.52 (0.8) l/min/m2, systemic vascular resistance index, pulmonary vascular resistance index and the gradient between central and peripheral temperature decreased, and oxygen transport parameters improved. Ringer's group patients needed more intensive infusion therapy (4050.0 (1102.2) ml in the Ringer's group, 3513.7(762.5) ml in the HyperHaes group). During the first 24 hours postoperatively, diuresis was significantly higher in the HyperHaes group (3640.0 (1122.9) ml and 2736.0 (900.7) ml), total fluid balance was lower in HyperHaes group (1405.6 (1519.0) ml and 2718.3 (1508.0)ml, respectively). After the infusion of HyperHaes solution, no adverse events were noted.ConclusionsHyperHaes solution had a positive effect on haemodynamic parameters and microcirculation. Oxygen transport was more effective after HyperHaes solution infusion. Higher diuresis, lower need for the infusion therapy for the first 24 hours and lower total fluid balance were determined in the HyperHaes group. No adverse effects were observed after HyperHaes solution infusion.
