Maternity Units Must Only Remove Gas and Air as a 'Last Resort'

Hospital trusts must only remove gas and air on maternity wards as a "last resort", NHS England has said. Several hospitals temporarily suspended the use of gas (also known as nitrous oxide) and air following concerns that midwives and staff are being exposed to too-high levels of gas over prolonged periods of time.

Some pregnant women have posted on social media, saying the decisions have left them feeling anxious and worried about their pain relief options.

Some NHS trusts have also come under fire for the way they communicated the message that gas and air would be suspended.

The NHS maternity survey for 2022 shows 76% of women used gas and air during their labour.

There are no harmful side effects of using gas and air for a mother or baby.

Clear Communication Needed

In new guidance to trusts, NHS England said it had looked at the health impacts for staff of levels of nitrous oxide exceeding prescribed levels, "drawing upon relevant legislation and existing guidance on the safe management of gas and air in healthcare settings". It said trusts must ensure they are compliant with legislation and national guidance on the use of gas, but must only remove it for women as a last resort and must tell them about other pain relief.

"Where, following the meeting of the (medical gas) committee, there is concern that the trust is not compliant, then this should be formally reported by the trust to the NHS England regional operations centre for the attention of the regional chief midwife," the guidance said.

"This report should outline the issue(s) identified, the actions the trust is to undertake to resolve and the timeframe for such resolution.

"The removal of gas and air provision for patients should be a measure of last resort, only considered following appropriate risk assessment, clinical consultation, and mitigation.

"Where there is no other option but to remove this provision, there must be clear communication with all service users who may be affected, with alternative options explained to support informed patient choice."

North West Anglia NHS Foundation Trust has been criticised over its handling of an announcement that it would be suspending gas and air. It then said it had made the decision to "temporarily suspend" it with immediate effect to "protect our midwifery and medical teams".

It added: "We are extremely sorry for the anxiety and uncertainty this announcement will cause.

"It was not a decision made lightly and is based on expert external advice which we cannot ignore.

"Our teams are working hard behind the scenes, with external companies, to resolve this issue as quickly as possible and we hope to safely re-introduce gas and air soon.

"None of us want our women to be without the option for gas and air during labour. We promise to communicate with you again as soon as we have an update."
