title: [Clinical monitoring of colloid osmotic pressure; a comparison of the performance of two oncometers].
abstract: The increasing importance of repeated measurements of colloid osmotic pressure, particularly in intensive care units and and anaesthesiology, is briefly outlined. The results of comparative measurements with two commercially available oncometers (Knauer Membran-Osmometer No. 1 and IL-186 Weil Oncometer No.2) are reviewed. In-vitro testing of the two apparatus with a 6.7 per cent albumin solution produced practically identical results. Measurements in the sera of patients after haemodilution differed slightly, the values being lower with No.2. Although this oncometer is faster and easier to operate certain draw-backs (related to calibration etc.) at present preclude its routine use by the untrained clinician.
