個案出現黏液水腫昏迷（myxedema coma）徵兆。護理師應預期個案處於何種生理狀態？

黏液水腫昏迷是嚴重甲狀腺功能低下所致的致命急症。特徵為嚴重的代謝低下，表現為低體溫、心跳過慢、意識障礙及低通氣量（Hypoventilation）。因代謝減慢，二氧化碳堆積，若不及時插管與提供甲狀腺素，易導致呼吸衰竭。

Myxedema coma is a life-threatening complication of severe hypothyroidism characterized by profound metabolic depression. This state leads to hypoventilation due to decreased respiratory drive, resulting in carbon dioxide retention and potential respiratory failure.

此為重症護理範疇，兩地皆強調需在加護病房監測，並由醫師執行靜脈給予甲狀腺素的緊急處置。
