Nitrous Oxide

In the United States, the most common pharmacological forms of pain analgesia for labor have been narcotics and local anesthetics through an epidural. Nonetheless, in recent years, there has been a growing awareness of the benefits of using nitrous oxide for pain during labor.

Benefits of Nitrous Oxide during labor:
  • According to the Journal of Midwifery & Women’s Health, “Nitrous oxide labor analgesia is safe for the mother, fetus, and neonate and can be made safe for caregivers. It is simple to administer, does not interfere with the release and function of endogenous oxytocin, and has no adverse effects on the normal physiology and progress of labor” (Rooks, 2011).
  • By not disrupting the release of oxytocin, nitrous oxide does not affect infant alertness during the early bonding period between a mother and her newborn.
  • It does not affect breastfeeding.
  • It does not increase the need for neonatal resuscitation.
  • In the doses given during labor, nitrous oxide is not a strong analgesic. Women who use nitrous oxide during labor may still have an awareness of labor pain. However, many women find it helps them relax and decreases their perception of labor pain.
  • Because it is self-administered, not only can a woman decide how much to use, but she can also decide if she wants to stop using it and try another method of pain relief instead. Nitrous oxide can be easily discontinued, and its effects disappear within five minutes after cessation.
While there are many benefits of using nitrous oxide during labor, there are some risks to be aware of. For example, side effects may include sedation, dizziness, nausea and vomiting.
