What Is Gas and Air? Everything You Should Know
In this blog, we'll discuss an essential tool for pain relief during labour—gas and air, also known as EntonoxⓇ.
If you're curious about what it is, why it's used, how to use it, its effects, and its applicability during c-sections, you've come to the right place. We'll also explore alternative pain relief options for c-sections.
What is gas and air (EntonoxⓇ)?
Gas and air, or EntonoxⓇ, is a mixture of nitrous oxide and oxygen. It is a popular form of pain relief used during labour and childbirth.
This colourless and odourless gas is self-administered by the labouring person through a handheld mask or mouthpiece, allowing them to inhale it as needed.
Why is gas and air used in labour?
Gas and air are used during labour to provide pain relief. It helps to 'take the edge off' the contractions and allows you to manage your discomfort better. It is also a great tool to help you control the rhythm of your breathing, which will also help you to stay calm.
It is a safe and non-invasive option that offers immediate relief, allowing you to control your birthing experience.
How do I use gas and air during labour?
Using gas and air is quite simple once you get the hang of it. You hold the mask or mouthpiece to your face/mouth and take deep breaths in and out. The mixture enters your lungs as you inhale, relieving pain within thirty seconds.
It's important to remember to breathe deeply and slowly when using gas and air throughout contractions to maximise the benefits. Once each contraction is finished, relax and breathe normally in between.
What are the effects of gas and air (EntonoxⓇ) in labour?
EntonoxⓇ helps to reduce the intensity of contractions and provides a sense of relaxation and euphoria. It doesn't eliminate pain but can help take the edge off.
Some people may experience a dry mouth or mild dizziness as side effects, but these are generally temporary and subside once the inhalation stops.
Is gas and air used for C-sections?
Gas and air are generally not used during c-sections because it requires the individual to self-administer the gas. In a c-section, regional anaesthesia, such as an epidural or spinal block, is typically used to numb the lower body and relieve pain.
It may be used in the lead-up to an emergency c-section while you are being prepared for and transferred to the theatre.
How long can you use gas and air in labour?
There is no specific time limit for using gas and air during labour. Most maternity units have the supply plumbed into the wall, so it can be used if you find it helpful.
Some people find it helpful throughout labour, while others may use it intermittently. You should discuss your pain relief options with your healthcare provider, and see how you feel when using it.
It's not for everyone, but you don't know until you try, right?
Is gas and air the same as laughing gas?
Yes, gas and air are commonly known as laughing gas. However, it's important to note that the concentration of nitrous oxide used for pain relief during labour is significantly lower than what is used recreationally and is generally very safe for you and your baby.
What other pain relief options are available for C-sections?
During a c-section, alternative pain relief options are typically used. Regional anaesthesia, such as an epidural or spinal block, is commonly administered to numb the lower body and relieve pain or sensation.
These methods ensure that you remain comfortable and pain-free throughout the surgical procedure.
If you would prefer not to be awake during your surgery, there is an option to have a general anaesthetic (GA). It is good to discuss all of these options with your care provider.
In summary, gas and air, or EntonoxⓇ, is a valuable tool for pain relief during labour. It allows you to manage your pain while controlling your birthing experience.
Although it may not be suitable for c-sections, other more effective pain relief options are available. Discussing your preferences and options with your healthcare provider is crucial to ensure a positive birthing experience.
