The aim of volume replacement is to compensate a reduction in the intravascular volume e.g.
during surgery and to counteract hypovolemia in order to maintain hemodynamics and vital
functions. To achieve this, different plasma substitutes are available: Albumin, dextran,
hydroxyethylstarches and gelatine. The aim of this study is to demonstrate that acid-base
alterations during elective abdominal surgery can be reduced by the use of a new gelatine
solution.
