甲状旁腺机能减退可表现为程度不同的各种症状,轻则人物性格改变重则肌肉强直。在甲状腺部分或全部切除术后5—28％的患者发生甲状旁腺机能减退。 Osborn等(1968)提出诊断甲状旁腺机能减退的几种方法:(1)游离钙饮食试验:甲状旁腺机能减退者经服游离钙饮食后症状减轻或消失,化验数据也有所改变。(2)磷酸排洩系数(PEI)测定:用的是Nordin及Fraser法,其结果若低于0.9则有临床意义。(3)连续血清钙测定:取血时不用止血带,其结果若低于8.5mg％,则为甲状旁腺机能减退的一种标志。
Parathyroid hypothyroidism can be manifested as a variety of different degrees of symptoms, ranging from the characters to change the weight of muscle rigidity. Parathyroid hypoplasia occurs in 5-28% of patients after partial or total thyroidectomy. Osborn et al. (1968) proposed several methods for diagnosis of hypoparathyroidism: (1) Free calcium diet test: The symptoms of hypoparathyroidism relieved or disappeared after dietary calcium intake, and the experimental data also changed. (2) Determination of phosphate excretion coefficient (PEI): Nordin and Fraser method used, the results below 0.9 is of clinical significance. (3) Determination of continuous serum calcium: No blood tourniquet, the results below 8.5mg%, then a sign of hypoparathyroidism.
