甲狀腺手術後暫時性低血鈣症

甲狀腺手術後引起暫時性的低血鈣症的原因尚未完全的明瞭。為了解不同的甲狀腺手術對血鈣濃度的影響，我們把甲狀腺手術的病例分成兩組，A組30例接受單側全葉切；B組30例接受全甲狀腺切除。在A組中術前術後血鈣離子都沒有顯著變化，但在B組卻有50％的病例發生暫時性的低血鈣症，發生的時間最短3天，最久49天，平均16.5天。低血鈣症大多發生在術後的第2天，有3例需要補充鈣離子緩解症狀。施行甲狀腺單側全葉切除或單側部份切的病人，不需要檢查血鈣離子，但對全甲狀腺切除的病人要特別留心，尤其已有低血鈣症的症狀時，必須經常評估血鈣離子的變化。

The causes of temporary hypocalcemia after thyroidectomy are still not well understood. We prospectively studied two groups of patients for evidence of free calcium change after two different modalities of thyroid surgery: group A consisted of 30 patients with unilateral total lobectomy; and group B, 30 patients with total thyroidectomy. Free calcium was unchanged in group A, but there were fifty percent of patients in group B had postoperative hypocalcemia. The duration of temporary hypocalcemial was from 3 days to 49 days (mean=16.5 days). Most of the postoperative hypocalcemia occurred on 2nd day after surgery. Only 3 patients required short-term of calcium therapy. There is no need to evaluate calcium level in the thyroid surgery less than unilateral total lobectomy, but we should keep an eye on the patients who are to receive total thyroidectomy. Frequent evaluation of the free calcium level is necessary when the symptoms and signs of hypocalcemia is noted.
