Callum Joe Guest v Nottingham University Hospitals NHS Trust
[2026] EWHC 704 (KB)·2026·Liability decided at trial
During long spinal surgery for scoliosis and chest wall deformity the claimant deteriorated, arrested while being turned over, and was left with severe sight loss. He alleged the anaesthetist negligently failed to treat a raised potassium reading, but the judge found that reading was spurious and the arrest was caused by a pulmonary embolism, so the claim failed.
Even after a devastating complication a claim fails if the court finds the true cause was a non-negligent event, so proving the mechanism of injury is often the decisive issue.
