    Study Notes

    Nitrous Oxide for Labour

    • Nitrous oxide (N₂O) is a colourless gas used for intrapartum pain relief.
    • It's fast-acting, safe, and effective for pain management.
    • Clients often report satisfaction when using N₂O, comparable to epidural analgesia.
    • Maintaining client mobility while administering N₂O is important.

    When Nitrous Oxide is Beneficial

    • Clients experiencing intrapartum pain, especially when dilated to >5cm.
    • Clients avoiding epidural, or waiting for epidural availability.
    • Clients experiencing anxiety during labour.

    How Nitrous Oxide Works

    • Analgesic effects: Increases endogenous endorphins, dopamine, and opioids in the brain.
    • It works in a similar mechanism to morphine.
    • Anxiolytic effects: Increases prolactin, decreases cortisol, and activates the GABA-A which is an inhibitory neurotransmitter, effectively reducing stress response.

    Benefits of Nitrous Oxide

    • Rapid onset (30-50 seconds) and quick offset (1-2 breaths of room air).
    • Maintains client mobility.
    • Does not affect uterine activity.
    • Non-invasive and cost-effective.

    Fetal Effects and Risks of N₂O

    • No effect on fetal heart rate, umbilical cord gases, or Apgar scores.
    • Crosses the placenta; however, the lack of lipid solubility prevents accumulation, and any remaining gas is eliminated when the baby starts to breathe.

    Adverse Effects of Nitrous Oxide

    • Nausea, dizziness, or vertigo.
    • In mixtures of 50% N₂O and 50% oxygen, respiratory depression or diffusion hypoxia might not occur.

    How to Administer Nitrous Oxide

    • Prepare equipment: Connect regulator, tubing, filter, mask/mouthpiece, and scavenging tube. Confirm sufficient gas in tank.
    • Inform client: Instruct client to inhale and exhale into the mask/mouthpiece during contractions and breathe room air between contractions.
    • Client to hold apparatus: Instruct client to hold the apparatus themselves. Avoid using straps to hold the mask.

    Supplies Needed

    • Nitrous oxide tank, regulator, filter, mask/mouthpiece, gas tubing, and scavenging tubing.
