甲狀腺切除術（thyroidectomy）過程中，副甲狀腺（parathyroid glands）極可能因位置接近或血液供應受損，導致副甲狀腺素（PTH）分泌不足。PTH 的主要功能是維持血鈣濃度。當 PTH 分泌受阻，血鈣會迅速下降，引發低血鈣（hypocalcemia）。護理師術後需密切觀察病人的 Trousseau's sign 及 Chvostek's sign，這是評估術後安全性的關鍵指標。
During a thyroidectomy, the parathyroid glands may be damaged or removed due to their proximity to the thyroid, leading to decreased parathyroid hormone (PTH) secretion. Since PTH regulates calcium levels, its deficiency results in hypocalcemia, making this a critical postoperative complication to monitor for signs such as Trousseau’s and Chvostek’s signs.
