Nitrous oxide, commonly known as laughing gas, has strongly returned to U.S. labor and delivery units after decades of decline. While epidurals remain the dominant form of pain relief, certified nurse-midwives (CNMs) are helping reintroduce this low-intervention alternative for patients seeking mobility, control, and comfort during childbirth.
The Return of a Historical Pain Management Tool
Nitrous oxide has been used in childbirth since the 1800s in Europe, and it became more widespread with the development of self-administration technology in the 1930s. It remained common in the UK, Canada, Australia, and Scandinavia—where over 50% of birthing women use it—while declining in the U.S. due to the rise of epidurals. A turning point came in 2010 when the American College of Nurse-Midwives (ACNM) endorsed its use. By 2012, the FDA approved updated equipment, increasing adoption in U.S. birth centers and hospitals.
Why Nurse Midwives Champion Nitrous Oxide
Midwives center their care on informed choice, physiologic birth, and minimal intervention. Nitrous oxide supports all of these principles. It offers moderate pain and anxiety relief while preserving freedom of movement and bodily autonomy.
1. Preserves Mobility
Unlike epidurals, nitrous oxide does not impair motor function. Women can walk, squat, change positions, or use birthing balls—tools that enhance labor progress and maternal satisfaction.
2. Promote Autonomy
Nitrous oxide is self-administered through a handheld mask or mouthpiece. Women control when and how often they use it, and its effects subside within 30–60 seconds of removing the mask. Autonomy supports the core midwifery value of patient empowerment.
3. Versatile Across All Labor Stages
It can be used in the early stages of labor, during pushing, and even for post-delivery procedures like episiotomy repair or manual placenta removal. This makes it a flexible option throughout the birthing process.
How Does Nitrous Oxide Compare?
| Pain Relief Method | Patient-Controlled | Mobility | Monitoring | Effectiveness | Side Effects |
|---|---|---|---|---|---|
| Nitrous Oxide | Yes | Yes | Minimal | Moderate (anxiety relief) | Nausea, dizziness |
| Epidural | No | No | High (continuous) | High (pain block) | Low blood pressure, immobility |
| IV Narcotics | No | Limited | Moderate | Moderate | Drowsiness, nausea |
| Unmedicated | Yes | Yes | None | None | None |
Safety and Clinical Support
Nitrous oxide has an excellent safety record. It’s used globally and has been endorsed by ACOG and the ASA. It crosses the placenta but is quickly exhaled by the baby after birth. Studies show no evidence of adverse neonatal outcomes.
Fast Onset and Offset
Nitrous oxide takes effect within a few breaths and clears rapidly from the lungs and bloodstream. This fast clearance prevents patients from using it anytime with minimal residual effect.
Minimal Monitoring and Interventions
No IV, catheterization, or continuous fetal monitoring is needed. This allows for a more physiologic and natural labor environment, especially in midwifery-led care models.
Emotional Benefits: Reducing Anxiety and Fear
Nitrous oxide doesn’t block pain but helps women cope with contractions by reducing anxiety and creating a sense of calm. This emotional support can significantly improve the childbirth experience.
Limitations and Considerations
- Does not eliminate pain; it is best for moderate relief
- Can cause temporary nausea or lightheadedness
- Not suitable for women with B12 deficiency, sleep apnea, or certain metabolic disorders
What Real Patients Say
“I felt like I was in control the whole time. I could breathe through the contractions, and I didn’t feel confined to the bed,” said one new mother who chose nitrous oxide under CNM care.
“Nitrous gave me just enough to take the edge off without feeling like I missed out on the experience,” said another.
Insurance and Cost
Many hospitals use nitrous oxide in standard labor care, especially in midwifery settings. However, coverage varies. In rare cases, patients have reported out-of-pocket costs, so it’s worth checking with your provider and hospital in advance.
Professional Guidelines and Adoption
The American College of Nurse-Midwives (ACNM) and American College of Obstetricians and Gynecologists (ACOG) support nitrous oxide as part of a full range of labor pain options. Clinical guidelines emphasize proper equipment, staff training, and air-scavenging systems to protect workers.
Frequently Asked Questions (FAQs)
Is nitrous oxide safe for my baby?
Yes. Nitrous oxide crosses the placenta but is exhaled quickly by the newborn with their first breaths. No long-term neonatal complications have been linked to its use during labor.
Can I switch to an epidural after using nitrous oxide?
Absolutely. Nitrous oxide doesn’t prevent you from choosing additional or more substantial pain relief later. It’s commonly used early in labor or during transition.
Will I be able to move around while using it?
Yes. Unlike an epidural, nitrous oxide does not limit mobility. If available, you can walk, change positions, and use a birthing ball or tub.
Does insurance cover nitrous oxide during labor?
Yes, in many cases, especially when administered in hospitals or birth centers with CNM-led teams. However, coverage varies, so always check with your provider.
Can I eat or drink while using it?
Light eating or drinking is generally allowed before using nitrous oxide, but it’s best to follow your provider’s labor diet protocol to avoid nausea.
Is nitrous oxide effective for pain relief?
It doesn’t eliminate pain like an epidural, but it helps you manage it by reducing anxiety. Many people report feeling calmer, in control, and satisfied with their birth experience.
Conclusion
Nitrous oxide during labor aligns with the values of midwifery: low intervention, high autonomy, and holistic care. It allows women to move freely, control their experience, and remain present throughout labor. With growing access and formal medical support, it’s a powerful tool in expanding the spectrum of birth choices.
