    Abstract:
    OBJECTIVES: To determine the efficacy and safety of intravascular volume augmentation with a hypertonic saline-hyperoncotic HES solution prior to CABG. DESIGN: Randomized, double-blind, clinical trial. PATIENTS: Consecutive sample of 37 patients scheduled for elective CABG; mean age 64.5 (41-80; range) years and weight 74 (51-111) kg. INTERVENTIONS: Continuous, central-venous infusion of either 250 ml (approx. 3.5 ml/kg) HES (0.9% NaCl/10% hydroxyethyl starch 200.000/0.5) or HT-HES (7.5% NaCl/10% hydroxyethyl starch 200.000/0.5) in 15 minutes, following induction of anesthesia. MEASUREMENTS AND MAIN RESULTS: Groups were similar with respect to age, weight, and sex. 15 min. after fluid loading, cardiac index, pulmonary artery pressure, and wedge pressure had increased from baseline in both groups (p < 0.05), with a greater increase in the HT-HES-group (p < 0.05). In eight out of 18 patients, who had received HT-HES, transient drops in arterial blood pressure (mean 20% from baseline, range 10-35%) were observed during the first 5 minutes of infusion. Seven of the HT-HES-group patients developed transient left ventricular failure, predominantly 5-20 min. after infusion. No incidence of initial hypotension or LVF was observed in the HES-group. CONCLUSIONS: In patients with coronary artery disease, volume augmentation with hypertonic-hyperoncotic solutions may induce transient hypotension and post-infusion hypervolemic left heart failure.
