Supports longstanding nitrous oxide use in labor analgesia; extends historical context but leaves modern administration optimization open.
A historical review of the use of nitrous oxide and air for pain relief during childbirth.
Cole et al. (1962) conducted a review in Pain relief during childbirth. Nitrous oxide and air was evaluated. Nitrous oxide has been used for over 80 years as a quick-acting inhalation analgesic for pain relief during normal labor, though early administration methods were not always optimal.
