血清中的钙大都与蛋白结合存在,而游离钙含量则很少,但后者在维持机体生理功能方面却具重要作用。血清总钙受血清蛋白浓度的影响,当血清白蛋白浓度低于4g/dl时,按下列公式予以修正。修正钙值=测定钙值+(4-白蛋白)。当修正后的血清钙超过13mg/dl,并伴有眩晕、嗜睡、精神错乱、昏迷等严重的中枢神经症状时,需要紧急处理。 治疗原则 1.原发疾病的治疗 引起高钙血症的三大主要疾病有:原发性甲状旁腺功能亢进;恶性肿瘤;结节病。前者可行手术切除甲状旁腺肿瘤,对恶性肿瘤也应积极治疗原发病。 2.一般治疗 去掉加重高钙血症的因素和处理并发症。如纠正同时伴有的其他电解质紊乱(低钾血症、低镁血症、低磷血症等);仃用升高血钙作 Most of the serum calcium binding protein exists, while the free calcium content is very small, but the latter in maintaining the physiological function of the body has an important role. Serum total calcium by the serum concentration of serum albumin concentration of less than 4g / dl, according to the following formula to be amended. Corrected calcium value = measured calcium value + (4-albumin). When the revised serum calcium over 13mg / dl, accompanied by dizziness, drowsiness, confusion, coma and other serious central nervous symptoms, the need for emergency treatment. Treatment principles 1. The treatment of primary disease caused by hypercalcemia of the three major diseases are: primary hyperparathyroidism; cancer; sarcoidosis. The former feasible surgical resection of parathyroid tumor, malignant tumors should also actively treat the primary disease. 2. General treatment to remove the factors that aggravate hypercalcaemia and treatment of complications. Such as correcting the same time accompanied by other electrolyte disorders (hypokalemia, hypomagnesemia, hypophosphatemia, etc.); Ding with elevated blood calcium
