Twilight sleep

Twilight sleep (English translation of the German word Dämmerschlaf) is an amnesic condition characterized by insensitivity to pain without loss of consciousness, induced by an injection of morphine and scopolamine, especially to relieve the pain of childbirth. This combination induces a semi-narcotic state which produces the experience of childbirth without pain, or without the memory of pain. The term 'Twilight Sleep' is also sometimes used to refer to modern intravenous sedation.
