住院病人发生重症低磷血症报道甚少,本文探讨住院病人发生重症低磷血症的发生率,诱因和临床意义。本文收集以色列一家大医院1980年～1982年住院病人全部血生化标本检测血磷浓度。55000份血标本中至少连续二次血磷偏低的120例作为研究对象。血磷浓度0.36～0.48 mmol/L(1.1—1.5 mg/dl)为A组(100例),≤0.32 mmol/L(≤1.0 mg/dl)为B组(20例)。 A组平均年龄52±5岁,B组58±3岁,无重症低磷血症者平均年龄为31±15岁(P<0.01A或B Hospitalized patients with severe hypophosphatemia rarely reported, this article discusses the incidence of hospitalized patients with severe hypophosphatemia, incentive and clinical significance. This article collected from a large hospital in Israel from 1980 to 1982 all in-patient blood biochemical samples for detecting serum phosphorus levels. In 55000 blood samples, at least 120 consecutive cases with low serum phosphorus were taken as the study subjects. Serum phosphorus concentrations ranged from 0.36 to 0.48 mmol / L (1.1-1.5 mg / dl) in group A (n = 100), and group B (n = 20) ≤0.32 mmol / L (≤1.0 mg / dl). In group A, the mean age was 52 ± 5 years, in group B 58 ± 3 years and in those without severe hypophosphatemia were 31 ± 15 years (P <0.01 A or B
