The effect of hydroxyethyl starch (HES) on different fibrinogen quantification methods in elective neurosurgery.
Background: Fibrinogen, a plasma protein essential for clot formation, can reach critically low levels during bleeding. The most commonly used method to determine fibrinogen is the photometric Clauss method. Intravenous colloid fluids can lead to falsely high values of fibrinogen when measured with the photometric Clauss method in comparison to an immunologic method. The main objective of this stu
