Objectives: To investigate whether starch-based colloid may impact differently on blood glucose than a gelatin-based colloid in adult patients receiving open heart surgery.
Methods: 70 adult patients scheduled for elective first-time cardiac surgery were enrolled and randomized into two groups. The circuits were primed with either 6% HES 130/0.4 or 4% gelatin. The peak glucose level, incidence of hyperglycemia, glucose variation and glucose level at different time points during operation were compared between the two groups. A p-value ≤ 0.05 was accepted as significant.
Results: The peak glucose (150±30mg/dl vs 142±27, p=0.236) and glucose variation demonstrated by standard deviation (26±12mg/dl vs 23±11mg/dl, p=0.202) were comparable between the two groups. Repeated measurement ANOVA revealed that the main effect for artificial colloid was not significant (p=0.349).
Conclusions: With the data available, we could not prove that starch-based colloid (HES130) had a different impact on intra-operative blood glucose than a gelatin-based colloid in adult patients receiving open heart surgery.
