Unconscious

From DwarfFortressWiki

When a Dwarf or other animal is caught by a dust cloud or sustains head damage in battle etc. it will fall unconscious. This means that the animal or Dwarf cannot move or enter combat. It is vulnerable to attacks. A dwarf knocked unconscious in combat it will need to be carried back to a bed by a conscious dwarf or by a trained animal. If the dwarf or animal was injured in combat, upon awakening it will require food and water. When unconscious you will not be able to make it do any jobs!
