A patient developed life-threatening pancreatitis after a gallstone-removal ERCP. The judge found the consultant never prescribed or instructed the standard preventive diclofenac suppository, so it was not given, and entered judgment for £550,000 against him.
Failing to give a recognised prophylactic drug before a procedure can be negligent even in private care. The prescribing doctor, not the hospital, carried the liability here.

A man with end-stage kidney failure was given a single 400mg gentamicin dose for a chest infection and suffered permanent balance and hearing damage. His sister's claim failed because the judge accepted that a high dose was a reasonable choice for a worsening infection with sepsis risk, despite his renal impairment.
A drug dose that causes known side-effects is not automatically negligent if it was a reasonable clinical judgement in the circumstances. Departing from a hospital guideline is not itself proof of negligence.

A 79-year-old with macular degeneration was persuaded to have an intraocular lens implant in her better eye without proper informed consent, then developed raised eye pressure that the surgeon left untreated for five weeks. Stacey J found the surgeon negligent both in consenting and in delaying laser treatment, causing total blindness in that eye.
Private eye surgeons must obtain genuinely informed consent and act promptly on post-operative complications. A delay that materially contributes to permanent damage is enough for liability even if some harm had already occurred.

A diabetic electrician's eye pressure rose to 40-56 mmHg in the days after retinal surgery and was managed with drugs rather than urgent further surgery. The judge held that continuing medical treatment was a logical clinical judgment supported by a responsible body of eye surgeons and dismissed the claim, including the late-raised consent argument.
Choosing medical management over urgent surgery is not negligent if a responsible body of specialists would have done the same. A Montgomery-style consent argument will fail if the patient would have followed the specialists' recommendation anyway.

[2015] UKSC 11·2015·Appeal decision
A diabetic mother of small stature was not told of the roughly 10 per cent risk of shoulder dystocia in a vaginal birth or offered a caesarean, and her son was born with cerebral palsy. The Supreme Court held doctors must tell patients about material risks and reasonable alternatives, replacing the old doctor-knows-best approach to consent.
Since Montgomery, a claim can succeed where a patient was not warned of a risk that a reasonable person in their position would consider significant, even if some doctors would not have mentioned it. It underpins most modern consent-based negligence claims.
