More than 120 maternity staff receive nearly £750,000 over nitrous oxide exposure
More than 120 midwives and other maternity staff at Basildon University Hospital have agreed a compensation settlement worth nearly £750,000.
They were exposed to high levels of nitrous oxide between 2021 and 2023.
The gas is used to relieve pain during labour, and the midwives’ union says it is safe for patients when used for that purpose.
Staff exposure was linked to poor ventilation and leaking gas lines on the maternity unit.
Workers reported fatigue, headaches, brain fog and anxiety.
An independent review found an unacceptable delay in addressing the risk, and said staff were exposed to unnecessary risk or potential harm.
The hospital trust apologised and said it should have acted faster.
It says it has since improved oversight of medical gas monitoring at the unit.

What people are saying
We're proud to have secured compensation for our clients, but they should never have been put at risk in the first place.
For years, midwives were breathing in nitrous oxide at dangerous levels while caring for women and babies. Even once the problem had been discovered, it was more than a year before staff were told.
We have acknowledged that we should have acted faster to address the issues and have apologised to staff.
