甲狀腺全切除術後，若不慎移除或損傷副甲狀腺，會導致副甲狀腺素（PTH）分泌不足，進而引發「低血鈣」（Hypocalcemia）。臨床徵象包括口周圍麻感（Perioral paresthesia）、指尖麻木、特魯索氏徵象（Trousseau's sign）與手足抽搐（Carpopedal spasm）。護理師應監測鈣離子濃度並備妥鈣劑。
After total thyroidectomy, if the parathyroid glands are inadvertently removed or injured, parathyroid hormone (PTH) secretion will be insufficient, leading to hypocalcemia. Clinical signs include perioral paresthesia, numbness of the fingertips, Trousseau's sign, and carpopedal spasm. The nurse should monitor calcium levels and have calcium supplements available.
