新近文献报道一种改良的诊断腹水的方法。其依据是已观察到门脉压直接与内脏毛细血管和腹水之间的胶体渗透压梯差呈比例关系。体液白蛋白浓度是维持胶体渗透压的决定因素。经实验观察确定血清与腹水之间白蛋白的浓度梯差(Albs-a),在门脉高压时为≥1.1g/dl,无门脉高压时则为<1.1g/dl。
A recent literature reports an improved method of diagnosing ascites. It is based on the observation that portal pressure is directly proportional to the colloid osmotic pressure gradient between visceral capillaries and ascites. Body fluid albumin concentration is the determining factor for maintaining colloid osmotic pressure. The concentration of albumin in serum and ascites (Albs-a) was determined experimentally to be> 1.1 g / dl at portal hypertension and <1.1 g / dl at no portal hypertension.
