Rapidly increasing in popularity in the US, nitrous oxide is a safe and affordable option for pain relief during labor in both hospitals and birth centers alike. With both anxiolytic (anxiety reducing) and analgesic (pain reducing) effects at low doses, nitrous oxide is becoming the choice of many women who want to forego or postpone more invasive options like an epidural yet wish to have some relief from pain intensity throughout labor and birth. Here are ten cool facts about the use of nitrous oxide during labor that you may not know!
- Nitrous oxide was commonly used for pain relief during labor in the US up until the 1960s and 1970s when the use of the epidural rapidly popularized. With the rise of epidurals, the use of nitrous oxide became virtually obsolete until around 2011 when midwives began bringing the practice back. You will now find nitrous oxide available for pain relief during labor in over 100 hospitals and over 50 birth centers in the United States.
- While the use of nitrous oxide for labor pain plummeted in the US with the inception of the epidural analgesic, the practice remained commonplace in other areas with sophisticated healthcare systems around the world such as Australia, Europe, New Zealand and Canada.
- While many believe that the nitrous oxide received during labor is the same as what you receive at the dentist, it’s actually less concentrated. When you utilize nitrous oxide during labor, the gas you are receiving is 50 percent N2O and 50 percent oxygen. Dentists use varying concentrations of nitrous oxide for their patients but can use up to 70 percent N2O and only 30 percent oxygen.
- Another way that nitrous oxide for labor is different than the nitrous oxide you receive at the dentist is that during labor it is controlled by the woman only. You will be given a handheld mask that contains a demand valve which opens to release the nitrous oxide when you inhale. When you exhale, the valve will close. This allows the woman in labor to use the nitrous oxide when she feels she needs it and to place it aside when she does not. This is much different than an epidural which is inserted into your spine and typically gives a continuous dose of analgesic throughout the rest of labor. Conversely, once you remove the nitrous oxide mask during labor, the effects will dissipate in about five minutes.
- While epidurals typically remove or greatly lessen the pain of labor, women who have used nitrous oxide report that they still feel the pain but their perception of it is altered. Because of the anxiety-reducing effects of the nitrous oxide, many women are better able to handle difficult contractions and other painful parts of the process with its use.
- You may begin using nitrous oxide for pain relief at any stage of labor or even post-delivery. There is no cut off in the process of labor when the treatment becomes unsafe making it a great option for moms who wish to try to make it as far as they can without any sort of medical intervention. Some mothers even decide not to use it until they are undergoing repairs following the birth for any tears occurred.
- If there was not an initial need for continuous fetal monitoring of your baby prior to your decision to use nitrous oxide, there will be no need for continuous monitoring after. You will still be free to move about, change positions, use a birthing ball or tub or any other position you wish to labor in after you have used the nitrous oxide. Your midwife or doctor will just want to ensure you are not experiencing any dizziness from the treatment before you go walking around but this is a quite uncommon side effect.
- There has been no evidence found that the use of nitrous oxide during labor slows the progression of labor at all. Particularly because you are able to move about freely in positions that are conducive to birthing, baby is able to further make his way into the birth canal. Nitrous oxide also does not impede the body’s natural production of oxytocin which is necessary for labor to progress.
- One of the most important factors to know when considering the use of nitrous oxide during labor is that it is safe for both mother and baby. Unlike certain narcotics that are often used during labor such as fentanyl, there is no risk of depressing baby’s breathing with nitrous oxide. It also should not negatively impact the infant’s alertness upon delivery and consequently, there should not be an effect on his ability to breastfeed and bond with the mother or father during the time period following delivery.
- Although unfortunately many insurance companies do not cover nitrous oxide treatment for labor at this time, the cost of nitrous oxide is significantly cheaper than having an epidural. And, unlike an epidural which requires a hospital birth and the presence (and a bill from) an anesthesiologist, nitrous oxide can often be offered at a birth center by a midwife.
