昏迷

A coma () is a prolonged state of deep unconsciousness in which a person cannot be awakened, fails to respond normally to stimuli (including pain, light, and sound), lacks a normal sleep-wake cycle and does not initiate voluntary actions. The person may experience respiratory and circulatory problems due to the body's inability to maintain normal bodily functions. People in a coma often require extensive medical care to maintain their health and prevent complications such as pneumonia or blood clots. Coma patients exhibit a complete absence of wakefulness and are unable to consciously feel, sp

AI overview

A coma is a prolonged state of deep unconsciousness where a person cannot be awakened and does not respond to stimuli like pain, light, or sound, while also losing their normal sleep-wake cycle and ability to take voluntary actions. Coma patients require extensive medical care because their bodies struggle to maintain basic functions like breathing and circulation, which puts them at risk for serious complications.

昏迷（拉丁語：coma）是指長時間的意识丧失（unconsciousness）狀態，無法被喚醒。在此狀態下無法正常感受到疼痛、光線及聲音，也無法對其作出反應，缺乏正常的甦醒-睡眠週期，而且不會啟動，無法自覺地有感覺、說話或行動。昏迷可以由自然原因或藥物所導致（請參考）。臨床上，昏迷可定義為無法持續遵循單一個步驟命令的狀態。也可用格拉斯哥昏迷指數量表（GCS）得分≤8，持續≥6小時，來定義。患者若維持在有意識狀態，他必然是清醒且有知覺的。清醒代表意識的定量程度，而有知覺則涉及大腦皮質所介導功能的品質方面，包括如注意力、感官知覺、外顯記憶、語言、完成指令的能力、時間和空間導向和現實判斷。從神經科學的角度來看，意識是通過激活大腦皮質（形成大腦外層的灰質）和網狀結構激活系統（RAS）（位於腦幹內的結構）來維持。
