The value of an albumin-based intravascular volume replacement strategy in elderly patients undergoing major abdominal surgery.
The value of human albumin (HA) for treating hypovolemia is controversial. Less expensive alternatives such as hydroxyethyl starch (HES) are sometimes refused because of unwanted side effects. We prospectively randomized 50 patients older than 70 years old undergoing major abdominal surgery to receive either 5% HA (n = 25) or a third generation HES preparation (6% HES 130/0.4; n = 25) when mean arterial blood pressure was <60 mm Hg and central venous pressure was <10 mm Hg. Hemodynamics, inflammation (interleukin-6), endothelial activation-integrity (adhesion molecules), coagulation (thrombelastography), and renal function (including kidney-specific proteins) were monitored after the induction of anesthesia, after surgery, 5 h in the intensive care unit, and on the first postoperative day. HA patients received 3960 +/- 590 mL of HA and 5070 +/- 1030 mL of Ringer's lactate solution, and HES patients received 3500 +/- 530 mL of HES and 4550 +/- 880 mL of Ringer's lactate solution. Total protein remained normal only in the HA-treated patients. No significant differences (P > 0.1) between the groups were seen with regard to hemodynamics, coagulation, and kidney function. Plasma levels of interleukin-6 and soluble adhesion molecules were significantly (P < 0.05) higher in the HA- than in the HES-treated patients. We conclude that HA in elderly patients undergoing major abdominal surgery can easily be replaced by a modern HES preparation. Because of the decreased inflammatory response and endothelial activation-injury, HES 130/0.4 seems to be the more appropriate fluid strategy for these patients.
