摘要
目的 通过测定甲状腺全切术后第1天甲状旁腺激素（parathyroid hormone,PTH）及血钙浓度,结合患者是否出现低钙血症及其伴随症状,判定PTH测定在甲状腺全切术后对于预测低钙血症的发生是否比血钙浓度的测定更具优势,从而为术后长期补充钙剂提供依据.方法 将104例甲状腺全切术后的患者,根据术后第1天PTH值进行分组,A组：PTH ＜5 pg/ml;B组：PTH介于5～10 pg/ml之间;C组：PTH介于10 ～ 20 pg/ml之间;D组：PTH＞ 20 pg/ml.同时测量每组患者的血钙浓度,记录每组发生低钙血症患者的数量,及钙剂支持治疗的持续时间.结果 PTH测定的准确率高于血钙浓度的测定,A组患者共26例,其中有7例存在暂时性低钙血症并出现低钙症状,5例出现长期低钙血症,需要长期钙剂支持治疗.A组的阳性预测值为28％,准确率为46％,均高于其他组,同时其阳性预测值及准确率亦高于血钙浓度的测定.结论 甲状腺全切术后PTH的测定比血钙浓度的测定在判断低钙血症的发生上更具优势,且术后PTH＜5 pg/ml是预测术后长期低钙血症发生的可靠指标.
Objective To determinate whether the first post-operative day serum parathyroid hormone （PTH） is more effective than serum calcium in predicting hypocalcemia after total thyroidectomy.Methods According to PTH level on the first post-operative day,104 patients after total thyroidectomy were divided into different groups.Patient＇s serum calcium was measured,the number of patients who developed hypocalcemia and the time for calcium supplement were recored.Results Serum PTH was more accurate in predicting hypocalcemia than serum calcium.There were 26 patients whose PTH value was ＜ 5 pg/ml,among whom 7 patients had transient hypocalcemia and symptoms,while 5 of them developed hypocalcemia for long time and needed long-term calcium supplement.The positive predictive value of group PTH value ＜ 5 pg/ml was 28％,and the accurate rate was 46％,higher than other groups.Besides,the positive predictive value and the accurate rate of PTH value ＜ 5 pg/ml was higher than serum calcium.Conclusion Serum PTH is more effective in determining hypocalcemia after total thyroidectomy than serum calcium,and PTH value ＜ 5 pg/ml on the first post-operative day is a reliable marker in predicting hypocalcemia after total thyroidectomy.
