Hospital bosses have been accused of launching a witch hunt to find a whistleblower who told a widower about blunders in the treatment his wife received.
The row emerged as an inquest began into the death of Susan Warby who died five weeks after bowel surgery.
Her family received an anonymous letter after her death highlighting errors in her surgery, the inquest in Ipswich heard, and both Suffolk Police and the hospital launched investigations.
These investigations confirmed that there had been issues around an arterial line fitted to Ms Warby during surgery, Suffolk’s senior coroner Nigel Parsley said.
Doctors were reportedly asked for fingerprints as part of the hospital’s investigation, with an official from trade union Unison describing the investigation as a “witch hunt” designed to identify the whistleblower who revealed the blunders.
Thursday’s inquest was told that Ms Warby had complained of abdominal pain and diarrhoea for around a fortnight before she collapsed at home on 26 July 2018 and her husband Jon Warby called the NHS 111 number.
The mother, known as Sue, was taken to hospital by ambulance and underwent emergency open surgery for a perforated bowel the next day, on 27 July.
Mr Parsley said that Mrs Warby was too unwell for her surgical incisions to be stitched up after the surgery and this was eventually done on 29 July.
Mr Warby said, in a statement read by Mr Parsley: “Following the operation Sue’s stomach was left open and she was taken to the intensive care unit.”
He said he was told that his wife was also suffering from a “rampant infection” which was putting a strain on her kidneys.
Mr Warby said he was told that during his wife’s operation, an arterial line was fitted with an intravenous (IV) infusion to keep it clear.
Ms Warby was incorrectly given glucose instead of saline, Mr Warby said.
“I asked what the effect of this could be and the consultant told me brain damage or death,” he said, adding he was later told there was “no new irreversible brain damage”.
He said that his wife’s condition was “very up and down” in the following days and her arterial line was replaced with a line into a central vein on 7 August.
During this operation, Ms Warby suffered a punctured lung.
Mr Warby said he was told it “could be a very tricky procedure” but that it was carried out by a “junior” member of staff.
“I’m concerned that a consultant should have performed the procedure due to her being critically ill,” he said.
He said that a week later, Ms Warby contracted a fungal infection and the family agreed to withdraw active treatment.
Ms Warby’s medical cause of death was recorded as multi-organ failure, with contributory causes including septicaemia and pneumonia.
The inquest heard she had been diagnosed with the digestive condition diverticular disease in 1997.
Consultant surgeon Dr Amitabh Mishra, who operated on Ms Warby, said: “Given how unwell she was, it was decided to proceed directly to an open operation.”
He said she was assessed as having an 84.8% risk of mortality, taking into account her underlying factors including her hypertension and that she was a smoker.
The inquest, listed for two days, continues.
