我清楚地记得签了同意anesthesia 表格，不是sedation，看了你的贴我问了AI

Yes, deep sedation is considered a form of anesthesia, sitting on the spectrum between moderate sedation and general anesthesia, where patients are deeply relaxed, often have amnesia of the event, and require careful monitoring, though usually maintain their own breathing unlike general anesthesia. It's a drug-induced state to control pain and anxiety for procedures, sometimes called "monitored anesthesia care" (MAC) when a professional monitors it, but it's distinct from full unconsciousness. 

所以那张表上的anesthesia 可能是指 deep dedation。
