Review Randomized Controlled Trial
Immune and inflammatory role of hydroxyethyl starch 130/0.4 and fluid gelatin in patients undergoing coronary surgery.
Compare the effects on inflammatory (TNF-α, IL-6, IL-8 and IL-10) and immunologic (CD3(+), CD4(+), CD8(+), CD11b(+), CD16(+)/56(+) T cells and total lymphocyte concentration) variables of hydroxyethyl starch 130/0.4, 4% modified fluid gelatin, or crystalloid when used as volume replacement fluids for acute normovolemic hemodilution (a blood conservation technique) in coronary artery bypass graft patients. ⋯ Hydroxyethyl starch 130/0.4 reduced pro-inflammatory responses and increased anti-inflammatory responses to a greater degree than gelatin solution and isolyte S®. The use of hydroxyethyl starch, compared to gelatin solution and isolyte S®, resulted in less decrease in the CD4(+):CD8(+) ratio, suggesting less immunosuppression.
