Nitrous Oxide vs. Epidural For Pain Relief During Labor

Pregnancy and Postpartum Care for Everyone

Both nitrous oxide and epidural are pain relief options used during labor, but they work in different ways and have distinct advantages and disadvantages. Here's an overview of each:

1. Nitrous Oxide:

How it works:

  • Nitrous oxide, also known as "laughing gas," is a colorless and odorless gas.
  • It is self-administered by the laboring woman through a mask or mouthpiece.
  • It is a mild analgesic that helps to take the edge off the pain without eliminating it entirely.


  • Nitrous oxide provides a more moderate pain relief compared to epidurals, allowing women to remain mobile and change positions during labor.
  • It is a self-administered method, giving the laboring woman more control over her pain relief.
  • Nitrous oxide has a short half-life, so its effects wear off quickly, and there are no long-term impacts on the baby.


  • Nitrous oxide may not be as effective as epidurals in completely eliminating pain.
  • It might cause dizziness or nausea in some women.

2. Epidural:

How it works:

  • An epidural involves the injection of a local anesthetic and sometimes an opioid into the epidural space in the spine.
  • This numbs the lower half of the body, providing pain relief during labor.


  • Epidurals are highly effective in providing significant pain relief.
  • They allow the laboring woman to rest and conserve energy, which can be beneficial during a long labor.
  • Epidurals can be used for both vaginal and cesarean deliveries.


  • Epidurals may limit mobility and the ability to change positions during labor.
  • There are potential side effects, including a drop in blood pressure, itching, and headaches.
  • The process of administering an epidural involves a needle in the spine, and there are risks associated with this procedure.


  • The choice between nitrous oxide and an epidural depends on personal preferences, pain tolerance, and the specific circumstances of labor.
  • Some women may choose to start with nitrous oxide and then decide if they need more intense pain relief, possibly progressing to an epidural.
  • It's important to discuss pain relief options with your healthcare provider, who can provide personalized advice based on your medical history and the progress of your labor.

Ultimately, the decision between nitrous oxide and an epidural is a personal one, and it's beneficial to have open communication with your healthcare team to make an informed choice based on your individual needs and preferences.
