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.

History

Developed in Freiburg, Germany, twilight sleep replaced chloroform, the previous treatment for childbirth pains popular during the 1800s. Developed by Carl Gauss, who began research on the treatment in 1903, it was also sometimes known as the "Freiburg method". However, Gauss was not the first to suggest the use of the combination of morphine and scopolamine as a surgical anesthesia; in 1899, a Dr. Schneiderlin "recommended the use of scopolamine, combined with morphia, for the production of surgical anaesthesia".
