Investigation and inquest
On 5 October 2016 I commenced an investigation into the death of David Robert Griffiths. The investigation concluded at the end of the inquest on the 31 January 2017. The conclusion of the inquest was a narrative conclusion as follows:
David Robert Griffiths developed a pleural effusion after a coronary artery bypass grafting procedure. During the procedure to drain the pleural effusion the pleural drain penetrated his heart causing it to stop.
Circumstances of the death
on 29 September 2016 at the University Hospital of Wales David Robert Griffiths underwent a procedure to drain a pleural effusion. The procedure was undertaken without the use of real time ultrasound guidance as this was not available. In addition, the drain was not inserted at the location identified and marked by an earlier ultrasound, although it was inserted in the recognised "triangle of safety". During the procedure the pleural drain penetrated Mr Griffiths’ heart (which is a rare but recognised complication of the procedure). Despite treatment he sadly died.
Coroner’s concerns
(1) The evidence revealed that there were no local cardiothoracic department protocols that were available to guide the insertion of intercostal drains and no specific training given to new medical and nursing staff.
(2) The British Thoracic Society Guidelines strongly support the use of real time ultrasound guidance when inserting chest drains for fluid. Real time ultrasound guidance was not available in this case.
