A doctor treating a woman for rheumatoid arthritis had no reason to believe she might suddenly die when she was sent to a Staffordshire hospital.
Dr Thomas Shearan said when he learnt of Patricia Leighton’s death he realised something “catastrophic” had happened.
It is alleged the 51-year-old’s death was caused after a doctor gave her a large injection of adrenaline after having ignored the warnings of other doctors and medical staff.
Dr Priya Ramnath, aged 40, has denied the manslaughter by gross negligence of Mrs Leighton from Burntwood, Staffordshire.
Dr Shearan told Birmingham Crown Court that there were problems treating Mrs Leighton’s condition and that in April 1998 she was enrolled in a controlled drug trial.
He said as a result she said she felt better but on July 20 she reported to be in a lot of pain and suffering from a wound on a bunion.
There was concern about her low blood count, he said, and it was arranged for her to be taken to the hospital the following morning to have the bunion cleaned out.
Asked about her condition, Dr Shearan said: “She was in quite a lot of pain, despite being on opiates. Otherwise she was not bad.”
Mr Michael Burrows QC, prosecuting, asked the doctor: “Did you have any cause to suppose she was so seriously ill she might die?”
The doctor said he did not and that Mrs Leighton was conscious, knew where she was and what her condition was.
Dr Shearan said when he learnt about her death two days later his immediate concern was the ten other patients who were on the drug trial.
Mr Burrows said after Mrs Leighton was taken to Stafford District General Hospital, Dr Ramnath administered the adrenaline despite the fact that two doctors present told her not to do it and without referring to the consultant in charge.
He said the doctor later resigned from her post at the hospital before moving to the United States.
The case continues.
