More than 100 maternity workers sue Basildon Hospital over nitrous oxide exposure
Published on 07/12/2026 at 05:47 | Redaktion boerse-global.de
More than 100 midwives and healthcare assistants at Basildon Hospital have launched legal action against the Mid and South Essex NHS Foundation Trust, alleging they were exposed to toxic levels of nitrous oxide over a five-year period. The group claims the trust failed to protect them from gas concentrations that reached up to 30 times the legal limit — a failure that has left many with chronic health conditions and raises serious questions about workplace safety in NHS maternity units.
Exposure levels '30 times the legal limit'
The legal claims centre on exposure recorded between 2018 and 2023. Testing carried out during this period revealed that staff in the hospital's maternity department were working in environments where nitrous oxide levels far exceeded workplace safety standards.
Nitrous oxide, commonly used as a painkiller during childbirth, can cause serious health problems when inhaled over long periods. Staff involved in the lawsuit report a range of chronic symptoms, including persistent fatigue, anxiety, headaches and cognitive impairments described as "brain fog".
Trust admits 16-month delay in telling staff
Internal records show that although the trust carried out environmental testing, the results were not shared with affected employees for 16 months. The Mid and South Essex NHS Foundation Trust has since acknowledged that this delay in communication was unacceptable.
The legal action comes amid wider scrutiny of the trust's operations. While the maternity department faces these claims, the organisation is also managing major infrastructure changes, including a recently approved helipad upgrade at Basildon Hospital and a new £8.9 million emergency department extension at nearby Southend Hospital.
141 claims received, £89,000 paid in settlements
The scale of the litigation has grown to include 141 total claims received by the trust. To date, the Mid and South Essex NHS Foundation Trust has paid £89,000 in settlements related to the gas exposure.
The case is progressing through the legal system, with the next High Court hearing scheduled for July 2026. The litigation unfolds against a backdrop of wider staffing pressures in the health service: national reports from the Royal College of Anaesthetists highlight a shortage of 2,256 anaesthetists across the UK, contributing to surgery postponements and operational strain.
