title: [The first labor analgesia with drug was already performed in late Meiji-Period (1868-1912): trace of opioid-scopolamine which was used in Akiko Yosano, back to its origins].
abstract: There have been some records of labor analgesia with intravenous or rectal anesthetics in early Showa-period (1926-1989). However, the author found that labor analgesia had been already attempted for some women in late Meiji-period (1868-1912). One of agents used was pantopon, a water-soluble opioid without serious respiratory depression as morphine. The drug was developed and produced in Germany. Some doctors applied this agent with scopolamine to labor analgesia in Europe. They also reported that this combination also conferred excellent analgesic effects without any serious complications in the mother and fetus. This combination was originally used for general surgery with inhaled anesthesia at that period. It remains uncertain how Japanese doctors got pantopon scopolamine from Germany.
